One Watt Light Bulbs!

ledisonLED lamps have been around for a while. But new products keep coming out that allow high-efficiency LEDs to replace more incandescent bulbs and drastically reduce energy use at the same time.

Mule Lighting now has their LEDison series of LED lamps which are meant to replace standard incandescent lights for decorative applications. Unlike most other LED lights, these fit into standard Edison-base sockets (hence the name LEDison.)  These can be used just like compact flourescents with no special fixtures required.  

LEDison lamps are being used to cheap levitra generic replace 10 to 60w incandescent bulbs in commercial applications (like shopping malls). The LED lamps have ten times the service life of the incandescents they replace, and use only 1 watt! An even greater cost savings is realized when the annual maintenance costs of replacing incandescent bulbs is considered.  Unfortunately, they're not yet being mass produced and are probably pretty expensive (since they wouldn't tell us how much they cost.) 

They don't quite produce the we choice levitra 20 mg amount of cheap tramadol overseas pharmacy light we usually expect from household lamps, so compact fluorescents are still probably a better choice, for now. But progress continues, and these are another neat little step along the way.

i have been asking myself one question for some time : what is the environmental cost of thos compact fluorescent bulbs ? they save energy, right... but don't they contain gas ? what happens to it when the bulb is destroyed ? can it be recycled ? is it ?
Flourescent Gas
written by a guest, September 03, 2006
Usually the gasses in flourescent lightbulbs are mostly innocuous (neon, for example, is completely inert.) But they do contain a small amount mercury vapour, which is bad for everybody. LED bulbs don't contain mercury, or any toxic substances at all. In that respect, they're definitely better.
great !
written by a guest, September 03, 2006
so that is definitely good news ! i came back to apologize for my question, as i saw later on your great site that the problem of recycling fluo lightbulb's mercury may soon be taken into account. smilies/smiley.gif

can you dim them?
written by a guest, September 04, 2006
I've got a lot of dimmers in my house and I know you can't use flourescents in them. Can you use LEDs?
Re: Dimmable
written by a guest, September 04, 2006
A single LED is not dimmeable, these "bulbs" contain multiple LEDs and if the base were smart the unit could be dimmable by disabling a portion of the LEDs when given less juice.

P.S. Your Bobdamn captcha is worse than most and does not work.

If you go to that site '' it states that using a dimmer might damage the LED 'bulb'.

Even though compact fluorescents contain a tiny amount of mercury, it's actually less mercury than is released by a power plant to generate the difference in power between a CF and an incandescent bulb. So even if you don't recycle it, you're still putting less Hg into the we use it womans cialis get cialis in canada environment.
True True...

But even the small amount of mercury in a CFL is more than is in an LED light :-)
Re: They Already Exist

dimming leds
written by a guest, September 04, 2006
you can dim leds if you pulse width modulate the signal. on that note, most people wouldn't bother, but if these bulbs become common enough someone will definitely make some modules...
written by a guest, September 04, 2006
Good point on the environmental strain. The process for producing LCD's is hardly a threat though. And there is no gas in LEDs. If anything, compact fluorescent bulbs are more environmentally unfriendly.

LEDs are toxic
written by Andrew Krause, September 04, 2006
The guy who claimed LEDs don't contain toxic substances is completely wrong. LED's use silicon doped with exotic heavy metals such as cadmium, cesium, arsenic, tin, and yes, mercury. Also, LED's are attached to circuits with electronic solder, which is 60^ lead, 39% tin, and 1% silver. Meanwhile, flourescent bulbs do contain mercury vapor.

In truth, it's six of wow)) buy canadian cialis online one, half a dozen of the other. A bad flourescent bulb doesn't contain enough mercury to even be noticed. (That's why they're bad - the mercury vapor leaked out.) You could eat a handful of LEDs, and your worst concern would be a perforated intestine - not poisoning.

led vs cfl vs regular bulb
written by JC, September 04, 2006
I think the mercury issue of cfl is offset by the electricity savings, remember in many places they burn bad stuff to make electricity which releases bad things into the air. I do not think LEDs are quite up to the benefits of cfl yet, but they are getting better all the time (plus they still cost quite a bit more.)

Toxic LEDs
written by Hank, September 04, 2006
There are a lot of ways to make LEDs, and lots of ways to solder. You don't have to solder with lead, you can solder with aluminum. You don't have to use mercury or aresenic in an LED and, largely, people don't. Sure, they can be toxic, but CFL's need mercury and LEDs don't.

No Illumination
written by Brad, September 04, 2006
I haven't been very impressed by LED lights. I got a couple led light bulbs about a year ago. They light up, but they do not illuminate. The ones I got supposedly replace 60w incandescents. They are about as bright as a night-light. They were pretty worthless for me, as far as light sources go. But they sure are pretty. $50 of pretty...

Are the LEDison bulbs any brighter than night-lights?
written by Republitarian, September 05, 2006
You enviro-wackos are funny. Careful, don't fart too much, might cause greenhouse gases. Mercury vapor in lightbulbs? LOL. I'm all for saving on my light bill, but you guys raise this shit to a religion. Ridiculous.
Hank is right
written by Robespierre, September 05, 2006
LEDs do not necessarily contain anything nasty though it is certainly possible that they would. 2-Watt LEDs are out ther and visit web site sales cialis 3-Watt lamps are just around the corner. CFLs are certainly better than regular incandescent bulbs, but I for one urge anyone out there who is working on advancing LED technology to hurry up! We are waiting for you.
Harmful, but Less Waste?
written by Paul, September 05, 2006
Perhaps CFs and LEDs have harmful waste products, but this may also be temporarily offset by their increased longevity, i.e., we don't have to consume as many as traditional incandescents?
Not an option .. yet
written by Mark, September 06, 2006
I'll continue to use CFL until something better comes along, but right now CFL are the best option available to me. When a better option presents itself, I'll use it instead.
Annoying flicker?
written by Mike, September 06, 2006
I got some LED christmas lights last year for our christmas tree, they look neat, but they flicker at 60hz (or whatever our power here alternates). It's barely noticable, but every once in a while I'd see the flicker as I turned my head. Do these lights flicker?
written by Larzie, September 09, 2006
I have to educate people on compact flourescents all the time. CFLs are fairly harmless if recycled properly. They can be broken down in a way that hardly allows anything to levitra ed be placed in a landfill unless you just throw it away! We are our own worst enemy with that (just simply being too lazy). With all the current reserch going into enegy efficiency, CFLs have taken a long first step. LEDs for commercial purposes, like exit signs and lights in the bathroom, just make sense.

I actually have several of these LED bulbs and they are nice, but the light is very dim. I was wondering if anyone else has the only now get cialis cheap 57 LED light bulb. Compared to the 18 LED bulb, how much more light does it give off? Does it shoot out the light in a wide range like a CFL or is it like a direct spotlight thing again? These bulbs are pretty expensive, but I like the lighting; it doesn't hurt my eyes - Still too dim.
LED Bulbs

I've look into the Lead issue with LED's and learnt that most of cheap cialis online prescription the companies that make these products are in Asia and most of there exports are 2 Europe. That said, Europe has strict Lead laws in products and most of these companies have changed there LED products to Lead free.
Anyways, I got some great 120V LED bulbs that were very bright from cyberguys website. Over 150 LED's in one bulb...I've ordered a bunch for my cottage that runs on solar with an invertor and they work great. I've ordered many LED bulbs in the past and these ones have the best quality I've seen and purchasing cialis with next day delivery reasonable price. One thing I noticed, the cheaper the LED product...the cheaper the quality.
LED are cool
written by Al Toman, October 23, 2006
LED contain gases within acrylic casings. The gas is ignited by the cathode-anode when powered producing the color (wave length) associated with the gas. White, blue, and green LED can be InGaN and red, orange, and yellow can be InGaAIP. Check the manufacture's product specifications. The older gas types degraded when exposed to UV (such as for outdoor signs).

The small amount of mercury in CPLs becomes a concern when you multiple 1 bulb by billions comsumed and disposed of annually. States such as NY adopted Fluorescent bulb disposal laws (2005).

LED can be dimmed by their very nature (D=diodes). The spec sheet for the lumidrive VariLED16 states "The MicroDriver 16 VariLED has two dimming options using either 0-10V dimming or dimming with a remote potentiometer." LED require constant current or voltage drivers since (household) or typical wall pack's fluctuate in output, taking chances in frying the LED. Try to use regulated output wall packs when working with/using LED.

LED require a ballast resistor, of sorts because they require very little energy to glow. Use E=IR to calculate the resistor needed when working with LED, depending on the voltage of your power source. Discrete white LED are typcially rated 3.6vdc at 30mA. Drive them at 20-24mA instead. This assures their longevity of about 11.4 years even though 30mA yields brighter light. Keep in mind that a 12v car battery yields more than 12 volts. LED degrade to 70% after about 5 years, typically, though not dramatically noticable to overnight tramadol the human eye.

You can use the LED calculator at to design your LED circuits.

The industry is shooting for 2010-2011 to market home-use LED light bulbs that are more acceptable in brightness, color, and price ;-)~

LED are cool. Not really. Your 60watt lightbulb yields 5% light and 95% heat energy whereas LED yield 90% light and 10% heat. High flux LED require heat sinking, else, they will eventually fry.
The efficiency of LED make them highly adaptable for solar energy (currently only 14-15% efficient). Shortly, I'll have a SOLAR-LED calculator posted so that you can calculate the size of your solar panel and battery to power your LED garden-pathway lights.

My small office is entirely illuminated with LED, only 6watts. And I won't be changing lightbulbs for the next 11 years, if I live that long~! 4watts of cool-white for background and 2watts of warm-white over my desktop keyboard. Cool-white reflecting off of buy tramadol cheap medication buy a white painted wall makes plenty enough of light.

Yup. LED are cool~!

Lead in LEDs
written by Parj Sangha, January 10, 2007

I have read some comments on here and i would just like to clarify that most LEDs such as Luxeon contain no lead or other hazardous products such as cadium as required by European law.

The soldering process has also been changed so that solder is now lead free. This is a more expensive process now but it is entirely lead free and meets EU laws

Before you spend a lot more of your money on those Wal-Mart garden light variety of LED solar lamps, let me get back to you in a week (when I'm out of the hospital).
I think that we can come up with solid solutions for you. SOLAR and LED applications are PURE MATH. We'll do the math and see what will work.

2-3-5watt illuminators will require some hefty solar, that is, if you really want them to work properly. There are other things, however, that we can do in your application.

It's a gas...
written by spam with everything, March 26, 2007
LEDs do not contain any gas as stated above. LEDs are constructed of two layers of semiconductor material doped (impregnated) with different impurites such as gallium, arsenide, aluminium etc. It is the different impurities that allow LEDs to be made in a range of colour outputs from infra-red right through the visable range and into ultraviolet.

I tried an LED, it broke on me within a few months of usage.

Its important to remember that even if they have a much longer lifetime, their electronics can still break.

Apparently CFL bulbs can die the same way.

Melbourne apparently has fairly dirty power which is probally the cialis tablets cause of the LED dying, the site where I brought the bulb from where selling another type cheaply because the electronics where susceptible to breaking when the power was dirty but only for one of the colours in the bulb. I assume the bulb I had was also to some extent susceptible, but since it was only one colour it died completely.

Quality of emitted light
written by LED Light Bulbs, August 31, 2007
As Marion Meyer has stated the quality of the light is still an issue for some specific applications where colour reproduction etc is an issue. Things have improved greatly recently though and for most the benefits (especially the long term economic and environmental) now make LED Light Bulbs such as these an increasingly viable alternative.

The summary is these new LEDs look great, quality-wise. They don't have that awful dead look that CFs can have. This is architectural usage, of course. If you're trying to do color proofing, that's a whole different ball game. Note that the new luxeon k2 is available in three distinct color tempratures.

I bought a 40W equivalent LED lightbulb at Wal-Mart this past weekend (Mar 22, 2009) for $5-6. It had a clear bulb covering several tiers of up-facing LEDs. Brand name started w/ an "F".

They also had an LED Party light for a little more, that allows you to pick a color or to let it cycle through the colors (abrupt or fade). I think it was $6.50 or so. It isn't very bright but it is very appropriate for parties or dim movie lighting. Cool!
