EcoGeek Video:Incandescents vs. CFLs vs. LEDs

Lightbulbs featured include:
The EarthLED CL-3
The Zetalux
The Evolux S
The Decor LED Accent

Leave your comment below for a chance at a free Evolux S.

UPDATE: Amazingly geeky ecogeek, Michael Cordingly has created an extremely useful spreadsheet (xls) for figuring out what lighting option is best for you. You can find out how much it's going to cost you over the levitra from mexico lifetime of the bulb, how much carbon it's going to pump into the atmosphere per year, and how frequently you'll need to cheap cialis online prescription change it.

I you're curious, the LEDs do best for carbon output, but they'll cost you more over the life of tramadol from china the bulb than a CFL with equivalent light output, even with the decreased energy costs. Thanks Mike!

It's great to see LED's actually entering the market. They still strike me as a bit too painful to the cash-flow to beat CFL's (especially when recycling them is becoming much easier) just yet, but economies of scale and http://dependablehealthcareservices.com/pa/joycejacob/cheap-cialis innovation should help to fix that. Thanks for the head-to-head comparison!

Hi, Hank. Neat site!

Man! The prices of the LED replacement bulbs are staggering -- especially the EvoLux and the www.sinai.org.il ZetaLux. Good products indeed, but still not even close to competitive in the marketplace. I've been making my own LED room lighting for 4 yrs but have run it/them on 12v.

What I'm waiting for is direct replacement 1/4 watt (or even 1/10 watt) LED 'bulbs'. That's plenty of light to navigate through a room on a dark night.

Keep up the good work.

I am just finishing teaching two sections of an environmental science course. I will use your clip next term - you made the comparison a lot of fun! If you are still looking for a home for the most expensive light bulb every made - I could use it in classes as demonstration!

It is exciting to see the LED technology mature, hopefully more cities and companies will make volume purchases of them and their impact is more widely seen.

I have heard about Organic LEDs, but I know little about them. Are any of these organic LEDs?

Also, with the $10 LED 'cheap' bulb, it looks like it might be... 12 leds? You might be able to make one by hand cheaper than that, if you knew what you were doing.

LED are great
written by DJ, December 10, 2008
Hello Hank, I lived in Missoula for several years while attending school. How is Montana? I miss it.
Anyway I'm a fan of www.fashionunited.info LED and I have been testing a couple out to see the effect on my electric bill. The problem is that they are low lumen. One is a great warm 1 watt... it works great for closets areas where you just need some light. Got it for $12.00 The other is a 5 watt for $30.00 and its incredible... though it the cold color vs. and its a spot beam. I would love to test a warm 40 watt LED for actual incandescent comparison. Let contribute to this as well. I'm lucky enough to live in a town that has an LED only retail store. That's all they sell, and they are always looking for new products and davenportinstitute.com tech. I don't have any affiliation with then other than I bought my lights there. Maybe they can help you with further analysis. Here is a link to there web site.

Nice technology comparison, but you need to upgrade from your kill-a-watt meter to something more precise like the wattsup pro.net meter from EED at wattsupmeters.com (they're a Denver company)Give them a call I'll bet they'll send you a review copy. My only comment is I seriously doubt the processor cooling fan will last as long as the http://sfachc.org/viagra-australia led light bulb elements on your $70 bulb- so it's probably not the best marriage of tech there. I've had to send back a number of tramadol order $1 CFL bulbs that died way before their lifetime, so I'd be pretty unhappy with a $70 led going bad due to its 30 cent cooling fan pooping out.

A fan in a light bulb?
written by Joe Larson, December 10, 2008
EcoGeek virgin here.

Okay, so they have to put a fan in the bulb for heat reasons so the bulb will last until the sun goes cold. What happens when the fan goes out? Granted that a problem our great^5 grandchildren will have to deal with, but still. And can you hear that fan in the room? Could be distracting that.

Thanks for great overview. My problem is that all the purchase levitra in canada ceiling lights are halogens. If I were to replace just 5 of them with LEDs, it will cost me around $200 Canadian.

Cheating on Watt-Equivalent
written by Carl, December 10, 2008
The video was nice, but it's kind of hard to tell the brightness. It seems like the main benefit of the LEDs are that they are directional. You can always get lower wattage by using a weaker bulb-- what matters is how much power to get the desired illumination. There seems to be a lot of cheating with "equivalent Watts"-- there is no standard (by law).

It would be interesting to see this video with measurements in a fixture, say for room illumination and for a reading lamp.

The LEDs may be half the wattage of the CFL, but the lux measurement is less/W except for the Evolux. Hard to tell lux out of a fixture, though.

The "30W Equivalend" CL3 says 200L/3W, or 67L/W. The Zetalux is 60W equivalent, but explicitly says directional, 350L/7W = 50L/W. The 100Weq Evolux is 1000L/12W or 83L/W. By comparison a 100Weq CFL says 1600L/23W = 70L/W, and another that claims 60Weq is 600L/11W = 55L/W.

If heat is the problem, why not make the fixture as well and spread the individual LEDs apart?

Seems like these LED lights are perfect for commercial displays, on all day with spot lights.

written by Darrin, December 10, 2008
First, I enjoy the site immensely and web prescription cialis find it very informative... but (you knew there was a "but" coming)

Second, you can't compare a 60-watt-equivalent CFL running at 15 watts to a 40-watt-equivalent LED running at 5 watts and the claim that the LED bulbs are 3 times more efficient. I've got an incandescent nightlight running at 5 watts, but I'm not claiming that it's 3 times as efficient as your CFL. Efficiency needs to be measured apples to apples, so the LED wattage needs to be scaled up by 50% to 7.5watts which makes it 2-times as efficient as the CFL.

Third - the LED with the fan will not last 50,000 hours unless the bearings in the fan can also last that long.

Wow! Who knew there were so many different lightbulbs out there... they're giving me a headache! But it's a bulb-tastic headache. I have the most energy efficient bulbs I could find. But there are a LOT more to choose from... There are awesome alternatives to those bulbs that people THINK are efficient when in fact they AREN'T as efficient as you'd think... *wow that was pretty confusing*

Only problem with the LED lightbulbs is.
written by David, December 11, 2008
80 dollars for a lightbulb is just too much, I'm all for the CFLs, I can pick up 4 of them for only 6 bucks at Walmart, cost vs. innovation, CFL's win. What happens if you have a power surge, a fire, or a flood. I'll tell you what happens, you lose everything because you spent all your money on LED bulbs so you had to cancel your home owners/renters insurance to pay for them.

Think "Cradle to Grave"...
written by Curtis, December 11, 2008
I read a lot of comments on the CFL vs LED dilemma, but in running a Science Camp Program in Northern Alberta, I usually like to teach the next generation to think about a "Cradle to Grave" perspective. Looking at things that way, LED's appear to have the greater advantage over CFL's purely based on the lack of a "grave" (and I am not sure how dangerous circuts are to dispose of after their 50,000 hours, i am assuming you can recycle them). Once you are done with CFL's the grave gets pretty nasty.
I like how this technology is making itself into the mainstream. I agree with some of the above posters that it is definitely not on a University student's budget.

Great Video!
written by Amy Thomson, December 11, 2008
It was really great to see the light bulbs in action. And it was cool to see our chief Eco Geek as well! I plan to run out and get those cheap deco LEDs for the lamp that takes them. About the only incandescents left in my house are dimmables. So, I'd love a link to a place that lays out which energy efficient lightbulbs can be dimmed.

What about...
written by OakMaster, December 11, 2008
Good video. I found it thru TreeHugger.com I think I saw you on walllofweird before, but maybe it was someone else.

What I didn't like about the video was the lack of depth in the comparison. I especially didn't like all the many many comments saying they were going to run out and buy one of the bulbs just because they saw a five minute video telling them it was 'more efficient'.

I am not claiming to be an expert by any means but what almost none of the comments took into consideration besides maybe Nathan, recyclemike and curtis, is the other factors included in the greeness of these lightbulbs.

Maybe I'm not ecogeek enuff and this is common sense but what are the different bulbs made out of? Are the companies making them supporting a green way of doing business?

My questions is... Aren't there other factors affecting how green a bulb is? Or is how many watts it uses the only thing we consumers should be concerned about?

Not trying to be negative but I would hate to have all these people running out to buy a 'more efficient' light bulb if the companies making them are using a less than green way of production or if they contain toxic materials.

I have not done research on the different products or the different companies mentioned but I will before I buy. And that really is my point to all the above posters, DO RESEARCH BEFORE YOU BUY. Find out what you need and what product is best for YOU.

I have a mixture of different types of bulbs and am skeptical that there is one that is the BEST.

oh and I have enough light in my house so I am in no need of another.

useful, but..
written by steve, December 11, 2008
It is nice seeing a comparison, but it is still too early for LED lamps. The payback over a CFL for most home applications is so long that it is better to wait for the LEDs to drop in price and use the cost difference between the CFL you have just installed and the LED to do something that saves much more energy - $50 into more insulation or weatherstripping is much more effective for example.

What we find useful is to plot kg of carbon emissions avoided or $ of energy saved as a function of the steps we take. Conservation (for us) beats efficiency hands down and some efficiencies are much better than others.

CFLs are still a better bet, for now
written by Michael, December 11, 2008
Light is measured in lumens, not watts. This comparison is pointless without lumen information and planning how much light you need.

Incadescent = 850
ZetaLux = 350
CFL = 870
EarthLED CL3 = 200
EvoLux S = 1000
LED Accent = ?

So the only comparable LD is the EvoLux S, which uses the same wattage as the CFL. You need 4 EarthLED's ($120 outlay) or 2 ZetaLux LEDs ($100 outlay) to match the lumen output of a $3.45 CFL.

If you're worried about carbon and cost, go CFL. LEDS are great, and there are good reasons to use them, but they're not ready if you actually demand the lumen output of your current lights.

For me it has only recently become economically viable to get CFLs, so I think I'm going to have to wait a good while for LEDs. If they can reduce the mercury content as planned, I think CFLs are going to be our best option for some time.

Thanks for the Spreadsheet
written by Paul Cantrell, December 11, 2008
Hank,
I appreciate the spreadsheet and the video. Helpful info.

The only things I would add to the spreadsheet are the lumens and lumens per Watt by bulb.

I added it to mine and found all the LED's and CFL have lumens/Watt in the mid-60's but only one of these LED lamps has significantly higher light efficacy than the 13 Watt CFL. The EvoLux S achieves 82.7 lm/W, while the CFL I use (Longstar) produces 63.1 lm/W. The standard incandescent is about 13 lm/W by the way.

These LED's are really becoming the real deal and I am recommending them in select installations.

I liked the info provided in this vid. I may not be able to afford to get the bulb being given away to one lucky poster, but I will be thinking about the others. I already use CFL. I buy the 40w equivalent when Walgreens has specials for like $0.99 each, and may have gone overboard at one time as I used to have a bag full. But since then I have moved and forgot my bag of CFLs so some lucky new renter has about 5 years or so worth of lighting.

Dimming
written by Ian E, December 12, 2008
CFL's are tough to dim. Most modern dimmers use PWM - they turn the light on and off really fast, and as they dim they're on less often - which CFL's really hate. The "dimmable" CFL's require a minimum turn-on level, and can't be dimmed under a certain amount. LED's excel at PWM and work perfectly with modern dimmers.

written by Paul, December 12, 2008
Someone like GE making LED light bulbs in quantity should lower price significantly. I purchased many CFLs for almost nothing, because the purchase was heavily subsidized by utility companies here in California. They will last long enough for me to finally see LED prices drop.

Mercury
written by Ross, December 12, 2008
Have you ever addressed the mercury content in CFL's? I think you could argue that if one lived in a market where he gets a significant amount of his energy from renewable energy that the incandescent is a better option for the environment. It'd be nice if we could fix the energy supply upstream at the source, and then it wouldn't really matter how many Watts a light bulb is pulling.

I'm late to finding this video. If you haven't given the bulb away yet, add my e-mail to the "hat". I thought you would like to see what I posted on yahoo, where I found your video today.

I'm excited to see that there are finally LED's on the market that can replace incandescents. I was at a physics conference recently and one of the scientists presented her research showing that the light quality of LED's had finally surpassed CFL's. I believe that LED's are where CFL's were several years ago on their cost curve. I'm sure the high cost of the 40 and 60 watt equivalency bulbs will come down. So if consumers can afford it now, or wait a little while until prices fall, we can have more efficient lighting than CFL's and without the mercury! Why is WFAA running adds for people to run out and buy CFL's?!!! People that see those ads, that don't mention the mercury content, will get bulbs that will help the environment from an energy stand point, but will have the potential for poisoning themselves that the environment due to the mercury content. Go LED!

Redesigning my house
written by Josh P, December 19, 2008
When I got this 1400 sq ft house about 18 months ago, one of my goals was to completely outfit the house with energy efficient LED lighting. I looked at several different options including LED rope lighting so that I could spread out the LED's so that they would not get to hot. Well, that was too expensive.
As I was watching this video and reading the comments, I had a NEW VISION!!! I would love to get a grid of LEDs that are all one inch apart that I could attach to the ceiling inside my house, and I would love to have heat or motion sensors set up to them so that as move throughout the house, the lights would fade in as I move into the area and fade out as I move out of it...in essence, creating a bubble of light around me. I would also love it if my illuminated ceiling could just have an even, dim setting that would give me the sense that there is no roof on my house; it would feel like the light is just flowing in from outside.
This all would be really cool, but it, too, might be a little expensive.

PS. It would even be sweeter if I could use the LEDs that could emit different variations of color...a completely rainbow ceiling!!!

LED lights
written by Matt, December 20, 2008
I have some LED night-lights in my garage, and no, they haven't lasted forever... they have a 50% failure rate (extreme dimming) over about a six month period. Luckily, I bought them at Lowe's and they exchanged them without a problem.
I look forward to LED lighting, as long as they try to match the warm color of incandescent, like the CFL's have tried to do.
I am a bit reluctant on using a light with a computer fan, as those tend to fail, too, and begin to squeal when their little fan bearing goes bad.

But, all moving in the right direction, and prices will come down to pennies on the dollar in the next 10 years.

Another option...CCFL
written by April, December 23, 2008
Great video! As an LED retailer, I am often discouraged by the lack of education available for LED lighting products. It seems like the industry has been content to just promote CFL’s as a way to be more energy efficient. This is what people need to hear about the advances in lighting technologies – thank you! I wanted to add a few comments:

First I want to answer the question about flickering (which could trigger migraines and has been known to aggravate children with autism) – LED’s do not flicker and good quality models, like those manufactured by CREE, emit a very soothing warm light.

Secondly, you left out a step in the incandescent to LED progression – cold cathode fluorescent lamps (CCFL’s). CCFL’s use a technology similar to neon. The bulbs are rated for 25,000 hours, can be turned off/on frequently without shortening life, are dimmable and contain 1/10 the mercury of CFL’s.

These bulbs are currently available in up to 40W equivalents (which use 8W of electricity) and retail for $20-$25. We have a wide selection available on our website: www.wattworks.com

It also messes around with my seasonal affective disorder and I bet an L.E.D. bulb would do just the trick.

I would love to get my hands on one of those LED lights, since the cost of electricity has gone up here, and though my usage has gone down considerably (thanks to power strips, and basically going to sleep earlier), the monthly bills are the same, if not more!

I like the Triten (sp?) CFL bulbs that I had purchased some time ago, maybe 10 years now, which have lasted me quite some time. The problem I have with CFL, no matter how compacted, is that some harps on floor or table lamps don't allow me to use them. It seems that these LEDs will fit the bill!

Please add my name to the giveaway. Thank you!

They worked great, very bright room and only 15 watts total, for about a week, then 'burned out'. BOOO What ever happened I do not know, they do not work on ac any longer, but I tore them apart and they work fine on dc if I rewire them to accept 12/24 volt dc.

written by arrogantb, January 23, 2009
computer fans fail - adding moving parts to a light bulb hits as a royally bad idea. with a price that high - I wouldn't be surprised if the fan failed before you made your money back (especially compared to a CFL).

even the zetalux didn't seem to light up the room as well as the 40 watt CFL. I think you'd need two of them to replace the light from a single 60 watt CFL ($160 vs $3).

thanks for the video - but it seems to me your over-selling the advantages of current day LEDs.

it would probably take a thousand+ dollars of LEDs to retro-fit an existing small house with reasonable light levels.

would seem to make far more economic sense to use CFL for now - then switch to LED when the prices come down (a lot).

What a great product!
written by Ash A, January 25, 2009
I have moved the whole of my house to CFL's from incadescents and saved a shed load of cash on my energy bills!

Now the LED bulbs are going to shave even more off the bill.?

Granted the outlay is a bit steep to start off with; however if they don't need replacing for 50,000 hours+ compared to the 15,000 hours of a CFL, then surely its better.?

Not that great.
written by Eric, February 01, 2009
These expensive evolux are not that great. The light was not even close to what a cfl produced as well as the cost was like 100 bucks when I bought one. In fact I had had to return it because I tried using it in my office fan light that had a metal circular casing and the light would turn off after certain time to protect against overheating. So now you can only use them in a regular lightning unit which in the end lights up the ceiling more than the room. Kinda pointless.

Ebay is cheaper!!!
written by joey Mantera, February 03, 2009
These led light bulbs are great i have about 6 of them from mr-16s (track) to standard e27(the regular bulbs) to par 38 ranging from 2.5 -4.5 watts. If you want to spend a boat load of money buy them off of earth led. If you wanna pay half or so you might want to browse on the wonderful world of ebay. I think for all six bulbs I must of paid about $100. Each bulb was anywhere from $15-25 bucks each, that's like buying a brand new music cd when cds where running $15 and up, remember those days, thank god for digital. Just buy one every now and then and you will see. One word of advise pay close attention to the lumens. A 200 lumens bulb is equivalent to 35-45 watt bulb which is ok on room fixtures with the glass shade, and works really great on reading lamps.
Now send me a free led light bulb.

i love LEDs and CFL lights.
written by Rick, March 17, 2009
I have 4 LED flashlights, and their batteries have lasted well over a year. Awesome! We are slowly replacing all our incandescents with CFL for now. I would love to see LED technology improve to the point where I could replace the light bulb on our church's LCD projector, so light wouldn't dim after 9 months. Anyway, thanks for your energetic and articulate presentation - who knew lightbulbs could be so exciting...and yet every time I go to WalMart, i gravitate towards that section! :-)

CREE LEDs: WE'VE GOT THEM AND LOVE THEM
written by Shira, May 11, 2009
We bought the cree recessed lights for our first floor of the house when we renovated. What a fantastic product!!! Very bright and beautiful colour. The light quality is WAY better than CFL's. People can debate the cost of CFL's and LEDs - but Cree's LED products kick CFL's ass when it comes to the beauty of the light quality. And, they're cheap to operate. And, you'll never have to change a lightbulb for decades!

It great to see someone make a video showing ppl the difference in the various bulbs out there and in my line of work I also show ppl the different color options and how to use the many color spectrums for the different applications through thier home or business. When I first switched to CFL lighting my electric bill dropped nearly $30 a month and I am now looking to slowly change my parents house to LED.

I sure could use that 100 watt LED bulb. Been out of work for a year. Employers tell me I'm too senior. Guess that means too old. Have been using CFLs to go green and save some green on the electric bill. Found some CFLs for $1.99 each and got em. That LED is cool but no way can I afford one. If you have some LEDs to share I got a home for them. Very Nice site. I enjoy your reviews. Regards, Mr. Out of Work.

EcoGeek forgot to look at POWER FACTOR
written by noneyet, May 23, 2009
Looking at watts is not enough. Many CFL and many LED bulbs have very LOW POWER FACTORS, which means they are burning anywhere from 1.5X to 5X more electricity back at the power plant than your home watt-meter says. This is because both LED and CFL bulbs designed to run on AC must have power conditioning/modification in order to work.

A 15W CFL with power factor 0.5 actually burns 30W worth of fuel and emits 30W worth of greenhouse gas back at the power plant. Some of the cheap LED bulbs (like Lights Of America's 5W floodlamp at Costco) have power factor as low as 0.3, which means that 5W LOA LED bulb is actually burning 15W of elecrical power back at the plant. Your electric meter is only showing the 5W, just like your portable power meter (like maybe the Kill-A-Watt® power meter), but the truth is that with a power factor of just 0.3, that 5 W bulb is a 15 W bulb in terms of actual energy consumed and pollution released. But it doesn't ahve to be that way.

Don't just buy any old LED bulb if you truly care about the environment and saving energy GLOBALLY. Insist on bulbs with the highest power factor you can get, and force all LED and CFL manufacturers to produce bulbs with high power factor. Don't buy their low-power-factor products! Insist on high power factors for true, global efficiency.

FOr example, the Cree LR4 and LR6 LED can lights have power factor > 0.95, which is excellent, and for that Cree should be awarded. But just because a bulb uses a Cree LED chip does not mean that the driver is also made by Cree, and it is the driver that determines the bulb's power factor.

If you don't have a power meter that can read out thepower factor directly, record the AC volts (usually 115-120 VAC or so) and the AC amps (for LED bulbs should be down in the 0.05-0.12 amp range), then multiply the AC volts by the AC current to get "VA" or volt*amps, and compare that value to the bulb's rated wattage. For example, the LOA 5W floodlight LED bulb from Costco I measured at 118 VAC and 0.15A, which when multiplied together results in 17 VA, which is another way to say 17 W. If the V*A measurements for your bulb don't closely match the rated W, then the bulb has a low power factor and you should not support that kind of behind-the-scenes trickery, you should trade it in for a truly "honest" bulb like Cree or Albeo Technologies with power factors greater than 0.95.

Do your research, people, don't be duped by the low watts of LED bulbs! Learn about power factor, and look at actual volts and amps and do the math yourself to check it. Only buy the ones with high power factors, IF you really care about the global impact.

LED's vs CFL's
written by Charly, June 21, 2009
LED's are definitely the greenest way to go. I would not allow a CFL in my home because of the mercury. People are not going to dispose of their CFL bulbs properly, and pretty soon all the fresh water fish will be contaminated with mercury, along with all the people who live in this country. You can't vacuum up a broken CFL, so what do parents do with a crawling baby in their house? Or pets? Or people who like to go barefoot, like me? Am I really going to get on my knees (after I've left the house for 1/2 an hour) to pick up the glass shards with masking tape? Am I really? No, I'm not. Am I really going to drive to the recycling station five miles from my home every time I have to replace a CFL bulb? No, I'm not. Is my elderly neighbor going to know what to do if she accidently breaks a CFL bulb? No, she's not. How about all the other million or so elderly people (or young, or blind, or handicapped?) Are they really going to be able to dispose of their bulbs? Those who object to my views bring up the point that mercury is in thermometers. Let me ask you -- how many thermometers do you have in your home? How many light bulbs do you use in your home? Multiply that number by a couple million. That's a lot of mercury. That is why CFL's are stupid. Stupid, stupid, stupid. It doesn't matter that they use less energy. The trade-off of massive pollution isn't worth it. Entire schools are evacuated when someone spilled a minute amount of mercury. And you want to replace all the incandescents in this country with CFL's? What we need, is a cool, efficient LED equivalent to 75-100 watt incandescent bulbs. Cool bulbs don't heat up their environment, so the need for air conditioning in the summer months will be less, even if it's just a small amount -- it will save energy in the long run more efficiently than CFL bulbs. And they contain NO MERCURY.

Error in spreadsheet
written by eric, July 05, 2009
There is an error in CO2 computation of the Lightbulb Costs spreadsheet. The raw CO2 figures are in units of lb/kWh. However they are applied to numbers that are in Wh.This corresponds to an overstatement of the CO2 generated by the various lights by a factor of 1000.

There's good news on that EvoLux bulb. It is rated as a 100 watt equivalent (not 60 or 70 as Hank Green said) and it is no longer $79.99 but can now be bought for $49.89.

However, there's bad news as well. I've read that the fan noise can be a bit distracting. Furthermore, although the stated 50,000 hours lifetime is equivalent to nearly six years of continuous usage, the warranty is only for two years smilies/angry.gif

I think I will wait a bit longer before buying any LED bulbs.

My Experience with Lights of America (LoA) Bulbs
written by Lar, October 08, 2009
I have been experimenting with bulbs from Lights of America. I can get a 5W (which kill-a-watts at 4W) for $13 at costco. Two or three would be ideal. I own at least one of every LoA LED bulbs available. I work every day under a 4.5 (Kill-a-Watt@2watts) bulb (2004LEDDL) I purchased for $10 at Wal-Mart.

I have a three fixture floor standing lamp that uses 3 LoA 2025LED-30k ($5.98 ea @ wal-mart). Each bulb is rated at 1.5 watts but the whole lamp with all three lights turned on consumes only 3 watts as measured by my (Kill-a-Watt). The only downside is there is a sort of hexagonal pattern that emtis from the bulbs, but they do broadcast light in a wider pattern than any other LoA bulb that I own. Much more like a dim standard bulb would work.

Most of the other LoA bulbs are very directional and require the addition of some form of reflection panel. In my basement I just use aluminum foil but a well placed mirror would work in an environment that requires a more elegant look. Ideally a larger version of the light casting cones found in the Soalr-LED used in gardens would provide the most "incandescent" broadcasting of light based on these designs.

I'm very interested in these bulbs you are giving away, they look alot like CFL light but without the mercury. I looked at some bulbs at Wal-Mart that run around $40 but I'm not quite ready to drop that kind of coin on a lightbulb.

I find that most CFLs rated at 13 watts take about 16 watts to operate. While LEDs often operate below their rated watts. That said a LED is usually about half as "bright" as advertised.

LEDs - a love/hate relationship
written by Green Consumer, October 27, 2009
I have purchased 45 LED bulbs and have had mixed reliability.
The good news - some are very reliable. I have five LED bulbs outside that have run dusk to dawn for two years with no problems.
The bad news - some bulbs are VERY unreliable. VERY high failure rates.
I purchased 12 of one type LED bulb and 7 have failed (8.5W product 47856 from LEDLight.com). To make matters worse they are refusing to replace them now.
Beware of LEDLight.com. This company is selling products that they know are defective. No support for failed LED bulbs. These bulbs are very expensive ($20 - $105) and in some cases last only two or three weeks. They refuse to replace defective bulbs. LEDLight.com is selling known defective products and has bad customer service.

Lovely. Watch out for sleep disturbance, have some _amber_ LEDs too
written by Hank Roberts, November 03, 2009
Found you via candlepowerforums.com reference. Recommending you everywhere.

Great film.

One note -- babies and old people in particular have fragile sleep cycles. The blue-green (475-500 nanometer) light range controls the human sleep cycle.

Best amber lights I know now are from Axxiom -- look up "turtle safe" LED light.

You'll see why this matters if you Google for it a bit.

You young adults have the most robust sleep cycles, but anyone with an infant, or anyone approaching 60, is susceptible to losing a lot of sleep from having any blue-white light during the sleep hours.

You can look this stuff up. Try Google Scholar (the filter here thinks it's spam, but you know how to use it)

(Color of blue sky through green leaves, duh, when that's gone from the environment, the primate most likely to have grandchildren will be the one that will find a safe place and fall asleep til sunrise)

Hi Hank,
While searching Google for warm white LED replacement units, I saw you're "You Tube" video. The Evolux S, warm white LED, looks like an ideal replacement for an incandescent bulb EXCEPT for the initial cost. Worldwide market competition will drop the price. Perhaps a peltier thermoelectric cooler might be used to help with the heating problem.

Thanks for the video and if you should still have a warm white Evolux S around I would put it to good use!

I personally wouldn't suggest jumping onto the CFL/LED bandwagon everywhere, especially in Canada. We used to have adverts saying how wonderful they were for the environment, but they stopped when studies showed the claims were wrong. In Canada's colder weather, the heat from incandescent is put to use, not wasted. And in areas where heating otherwise comes from fossil fuels/wood, it is actually more environmentally friendly to use the incandescent bulbs and not rely on 'bad fuels'.

EcoGeek Compares CFL Incandescents and LED lightbulbs
written by Susan Binkley, March 19, 2013
Thanks for the information! So far, I've only changed to CFLs, but feel encouraged now to try some others. I bought a new home almost 7 years ago and changed all bulbs to CFLs upon moving in. I am just now having to replace the heaviest used ones. I'm amazed at the lifespan when comparing to how many I would have changed by now if I hadn't updated.
