It is matter of time before they will come to 5$. I cannot see how flourescent can compete with this - Peter Calka Sat, 23 May 2009 00:42:29 +0100 http://www.ecogeek.org/efficiency/2576#comment-25339 sorry, 1200mm-20W :2000lumen - Rocky Mon, 23 Mar 2009 10:18:48 +0100 http://www.ecogeek.org/efficiency/2576#comment-25338 www.worldportables.com provide new technology SMD 5050 LED fluorescent tubes .. surprising price :$37 MSN: huangyan32@hotmail.com skype: huangyan32 Length 1200mm-50W 2000lumen - Rocky Mon, 23 Mar 2009 09:37:29 +0100 http://www.ecogeek.org/efficiency/2576#comment-24850 I am neoseikan, the producer of Neofab Legion II, the brightest single LED flashlight. It has 742~748 real torch lumens. Would you like to write an article about these kind of strong light LED flashlights? If you are interested, here is the link: http://www.cpfmarketplace.com/mp/showthread.php?t=191371 Thank you! - neoseikan Fri, 06 Mar 2009 11:47:52 +0100 http://www.ecogeek.org/efficiency/2576#comment-24702 There has always been some smoke and mirrors to LED marketing. In terms of the smoke in the Bikei copy, Bieki has claimed that a conventional fluorescent lamp has a 5,000 hour life. Bikei is comparing apples and oranges here. Small, old fluorescent tubes used on magnetic ballasts such as an F4T5, have a 5,000 hour life. IMO, Bikei needs to benchmark its product against a modern T8 or T5 fluorescent lamp used with a high frequency electronic ballast. Current T8 systems reliably deliver 36,000+ hours @ ~2700 mean lumens and thus would force Bikei to restate it's ROI. If you look at induction sources (RF excitation of mercury and phosphors), the life pushes to 100,000 hours. - Jeffrey Augustine Mon, 02 Mar 2009 19:31:47 +0100 http://www.ecogeek.org/efficiency/2576#comment-24431 My company develops LED street lights, which save up to 40% energy compared to gas discharge lamps and also live three to four times longer. LEDs hold an enourmous potential in reducing energy costs for all kinds of lighting purposes. I my best estimate, LED technology is currently at a breakthrough point: In four to five years, we'll see much more LEDs being used for interior as well as exterior lighting purposes. - Chris Sat, 21 Feb 2009 05:54:20 +0100 http://www.ecogeek.org/efficiency/2576#comment-24423 It's not an equivalent "drop-in" replacement-- you have to consider the light output. This LED light gets 370 lumens, but the normal T-12 bulb is >2800. So as Chris writes, this LED light is >4X less efficient than a normal bulb. If you simply take out one of a pair of bulbs, you get the same savings in energy, but 4X more light. This LED light is so dim that you can get almost the same effect as just turning off the light. - Carl Fri, 20 Feb 2009 18:18:03 +0100 http://www.ecogeek.org/efficiency/2576#comment-24407 Ok, why are they trying to make it look like a fluorescent tube? The whole benifit of the fluorescent tube is that you get a full 360 degree output and can therefore design the accompaning reflector system to suit. This LED cuts out some of that spectrum. Am I missing something? Also, superior colour quality to fluorescent? C'mon, you can get high CRI fluorescent lamps in a variety of Tk color temperature ranges. The colour argument over fluorescent has been dead for years. - ugottawonder Fri, 20 Feb 2009 05:13:07 +0100 http://www.ecogeek.org/efficiency/2576#comment-24401 Labor costs for install need to also be included in the cost/benefit analysis. These reduced labor costs may affect the timing? How many MTA employees does it take to change a lightbulb? How much does that cost? :) - Shawn Lancaster Thu, 19 Feb 2009 20:44:55 +0100 http://www.ecogeek.org/efficiency/2576#comment-24397 Better price, $149, from Company in VT [url]http://www.leddynamics.com/[/url]. [url]http://www.everled.com/everled-tr/[/url] was the first commercially available fluorescent tube replacement utilizing clean, safe, and long lasting LED technology back in 2007. They won Popular Science's Best of What's New and EC&M's Product of the Year 2008. Their company rocks. - Heather Thu, 19 Feb 2009 19:11:26 +0100 http://www.ecogeek.org/efficiency/2576#comment-24391 I'm assuming that someone checked to see if there is a long term savings to having these drop in lights which are still connected to a ballast. Would it be better/more efficient/save money to simply make fixtures that could easily be swapped out for flourescent fixtures (so that they fill the same typical area in a ceiling tile grid). - shek Thu, 19 Feb 2009 16:26:45 +0100 http://www.ecogeek.org/efficiency/2576#comment-24390 bioleds have the future... - jvr Thu, 19 Feb 2009 16:11:28 +0100 http://www.ecogeek.org/efficiency/2576#comment-24388 Something has got to be wrong, because that's only 18 lumens/watt. My electronically ballasted T-8 bulbs get 92 lumens/watt. (That is, at 32W they produce 2950 lumens.) And these are sunshine bulbs, i.e. they have a balance of phosphors which give variety in the output spectrum. - Chris Thu, 19 Feb 2009 15:32:38 +0100
