New Dimmable Bulbs Could Save Gigawatts

Twenty-two percent of America's power is used to create light. But a well-kept secret is that over half of that light comes out of bulbs that you've likely never seen up close, and certainly haven't ever bought.

They're the high intensity discharge (HID) lights that give the world's supermarkets and click here buy real viagra Wal-Marts that brighter-than-sunlight feel.

While HID lights are pretty efficient, especially when compared with incandescents, they have a few pretty serious problems. They take about 10 minutes to warm up, and they can't be dimmed. And, of course, no one would complain if they were a bit more efficient.

Well a startup called HID Technologies has developed a new digital ballast for HID lights that fixes all of online levitra cheap those problems. The new technology could cut energy use by HID lights by 40%. Altogether this tremendously unsexy technology could save gigawatts of power.

The power would be saved by allowing stores to dim lights on sunny days (in concert skylights), allowing lights to turn on instantly (so they wouldn't have to stay on all the jesperoffice.com time), and simply because the new technology makes the lights more efficient, with a 320 watt new HID lamp being roughly as good as an old HID lamp.

Of course, it's a change that none of us will likely even notice, but in the end, that's the best kind of environmental innovation.

Similar practices already in use
written by shaun, August 28, 2008
The trick here is making the tech affordable.

I've already seen similar systems in use in WalMart with flourescents and skylights. The company will have to make the systems as cost effective as that.

I've also read about similar setups for the home coupled with Solatube type skylights and CFL's.

Now if they could make the lights efficient enough to use viagra run on solar alone ...

There's also the viagra no presciption other positive knock-on effects of this as well, such as because less energy is being used, less heat is being produced, so less cooling/AC will be needed.

Do mean "(in concert *with* skylights)"?

And how about giving us the wattage of the old HID lights? 320 watts vs. ~540 watts?

Gosh, go a big step further. If all HIDs were updated how many dirty coal plants could we close?

How quickly could a Wal-Mart recover the changeover cost?

This is an important development as businesses really understand the bottom line. Successful businesses know how to spend a buck to save two bucks unlike Joe Schmoe who's still burning incandescents.

I guess you don't live in Minnesota. We need all the heat that we can get. ;)

How is it's cool canada cialis no prescription he able to spam like that?!? I usually have trouble making one post, let alone the same one 6 times!

As for not living in Minnesota, I'd imagine it'd take more energy to actively cool an area with AC, than to passively keep somewhere warm with insulation.

Also, it seems to be 320 watts from the current 450 watt bulbs.

Although, with all the recent improvements in LEDs and such, they might soon replace HIDs, such as they have in some streetlights (although current HID's are more efficient than CFLs, so these new ones may already be better than LEDs for certain applications).

Try "efficacious" and "efficacy"
written by Spuffler, August 28, 2008
Lumens (of light) per watt (of electrical power) is a ratio of unrelated quantities. Because, with HID, you will always draw electrical power to cheap fast levitra create lumens of tramadol 120 light, you cannot properly call it "Efficiency". "Efficiency" would be appropriate to describe power converters, where watts come out after watts are consumed. My comment draws from industry terminology (IESNA); I've worked as a development engineering technician for HID electronic ballast development (re: Sylvania BA800SE and other HID lamps), and prior to that I had developed a family of DC to DC converters at an OEM.

The proper term for 'lumens per watt' would be "efficacy", you would want lamps that were more "efficacious", not more "efficient".

Regarding dimmability, it could be tricky in the real world; getting a row of dimmed HID lights to appear to be the www.artstlouis.org same intensity is already electrically unpredictable, but in the end, after they all stabilized at their 'new' temperatures (assuming the row of HID lights would all be commanded to run at the same watts AND assuming all the luminaires were at similar environmental conditions), they should be relatively similar in intensity... after a while. If there is no added cooling on one lamp or another. If the lamp manufacturer has engineered the lamp chemistry accurately enough so that from one lamp batch to the next lamp batch, the lamps responded with the same lumens for each wattage. That last point is forced on where to get viagra cheap the lamp maker: if batch to batch luminosity variations exist as they once existed in the past, imagine telling a WalMart facility engineer that a whole row of (PRICEY) HID lamps has to ALL be replaced (with lamps from the same production batch) when one has failed, because the other batch has different luminousity characteristics.

FWIW, the software running this website did not refresh the bestellen levitra online new page after I submitted my comment, hence I wouldn't have seen the web page change AT ALL, and I might have submitted several times. Hence, try to cheap viagra without prescription be forgiving of Mr. Wallace, he probably thought nothing was happening, just as I felt moments ago.

Hey Hank Green: try asking around in the support forums of this software: is this problem (e.g., failure to refresh after submission) just a FireFox issue, or does the software fail to refresh for other browsers? Me, I'm not about to change web browsers for the benefit of any website software.

efficacy?!?
written by Clinch, August 29, 2008
@Spuffler

It could still be efficiency though, as you're converting electrical energy on to light energy, and as they're both energies, they are related quantities.

As for the web page refreshing and such, it does happen, it just takes a while (sometimes over a minute).
But the comment submission has something on it so you can't post twice within two minutes, so I still think he's purposely spamming.

And the blog hosting software used seems to be bad on all browsers (and by 'all' I mean both IE and FF), but it sees that there's something in the works to update this site to something that runs better (or I think there was).

Dimming HID is not new, but we should us
written by Corey B, August 29, 2008
Dimming for an HID lamp is nothing new; this technology has been around for years. It requires the purchase of special ballasts which is non-standard in most manufacturers’ standard luminaires. These ballasts are often much heavier and bulkier than today’s electronic ballast technologies and often cannot fit into the off-the-shelf luminaires. I had this installed on a lighting design project about 7 years ago. Don't get me wrong, I am all for it, just don't call it new.

Spuffler is correct on the efficacy argument but because the ballast is overight delivery viagra essentially regulating the generic viagra with paypal voltage output to http://www.blickueberdenzaun.de/canadian-viagra-50mg each lamp the intensity of tramadol for cats each lamp should be very similar.

It is difficult to get a client to buy into this technology when they are too often confronted with rising upfront building costs. I applaud those who see beyond the initial investment years and realize the longevity of energy savings turning into profitability in the long term.

Buggy software here. As I've emailed Hank multiple times.

I hit "Add" and nothing happens (except for a little pinwheel spinning). Sometimes my posts adds, sometimes not.

Yesterday I just left the page tab open and http://www.jubileecampaign.nl/levitra-for-sale-online hit "Add" periodically through the day.

I'd say about half or less times the post added.

Way past time to fix this problem. Perhaps someone could donate a few minutes and take care of this. It's got to be a minor problem.

HID Tech
written by Sean Kidd CEM, September 02, 2008
Hi-low systems have been around for about a decade, warehouses would use them to "dim" aisles with no activity via a motion sensor, once sensor tripped, his would go to full brightness, however this was a fixed level of dimming not a variable one. Daylight harvisting is a requitement of Epact 2008, therefore this technology would be ideal for new construction.

BTW a standard 400W MH draws 460 Watts with magnetic ballast.

How about dimmable LED high bays?
written by tracy, September 05, 2008
(Warning: shameless, but relevant, plug coming)

My company, Albeo Technologies (http://www.albeotech.com), makes a high bay LED fixture, with comparable lumen output and efficacy to cheapest viagra in uk metal halide. One significant difference, however, is the dimmability. Albeo's high bay LED fixtures are fully dimmable from 0 to 100%. However, LED becomes significantly more efficacious when dimmed, while HID or fluorescent becomes less. In addition, LED fixtures last many times longer than either of those technologies.

Efficiency != efficacy
written by Nate, September 25, 2008
@Clinch

Under that definition, incandescent lights are 100% efficient, since we're also counting "light energy" in the infrared!

Check out what lumens really are. Basically it's a weighting based on official canadian pharmacy how well our eye can see different frequencies of light. So infrared gets no points (even if there's lots of drug generic cialis energy there), blue a little, green a lot, red not so much, and so on.

They're really not compatible, so efficacy is the correct word (how *effective* it is).
