They have more to gain than a pot grower, Brillioins of $ would be saved IF they were usable. Yes there are a few desk lights that have leds, but, does industry use them. GE,Siemens,AG,Silvainia(sp) have some of the best engeers going. I can only hope pot growers can prove them wrong. Wind power, solar cells (subsidies pay 14-25 cents per kwh to cover cost rich get richer poor get poorer:wtf,bio fuels (consumes more power than they net rich get richer poor get poorer:wtf:, battery power (1919 2007 80 miles to a charge almost 90 years later net gain 0,, ZERO net:wtf , Someday they will make,leds output to cost ratio:thumbsup:.
Believe me I am all for new things, my system is automated, remote control.
This thread is how old and not yet has one person come up with watts/grams/month
NOTE if you do make it work, you will make more from GE, Seimans than you will ever make from growing pot.

OK its not grow lights but industry is using LEDs and and it will explode this year. The innovations needed have arrived.

Lighting Industry Survey Confirms LED Lighting Market Growth

By the end of 2008, LEDs are expected to be commonly used in offices, parking garages and residential outdoor applications

DURHAM, N.C., JANUARY 28, 2008 ?? Cree, Inc. (Nasdaq: CREE), a market leader in LED solid-state lighting components, announces the results of an independent survey on the adoption, deployment and benefits of LED lighting. The survey, taken at the recent 2007 Hong Kong International Lighting Fair, validates strong global growth for LED lighting applications, confirms awareness of the energy-efficiency benefits of LEDs and indicates that the adoption trend should continue through the end of the decade.

Key survey findings include:
* Nearly three-quarters (72 percent) of respondents have witnessed a growth rate in excess of 20 percent for LED lighting applications in their businesses over the past six months.

* Almost two-thirds of respondents (63 percent) believe LED lighting will comprise more than 50 percent of their sales or installations by 2009.

* Future growth in the LED lighting market is expected to come from a mix of applications ?? with street/parking (20 percent), residential indoor (17 percent), retail/display (17 percent) and office (15 percent) cited as the leading opportunities.

Survey respondents represent top decision-makers at lighting manufacturers who attended the 2007 Hong Kong International Lighting Fair ?? the largest lighting show in Asia and the second largest in the world. Nearly half the respondents to this survey were from outside of Asia, reflecting the survey??s global reach.

??The survey results present us with a clear and positive picture of growth patterns and expectations from leaders in fixture design and manufacturing,? said Greg Merritt, director of corporate marketing, Cree. ??The survey shows an increasing demand for the high-quality, energy-efficient LEDs that Cree currently provides and is continuing to develop.?

??The general illumination market is at a tipping point,? Merritt said. ??Cree??s industry-leading XLamp? family of high-performance cool- and warm-white LEDs is uniquely positioned to serve the needs of lighting manufacturers who are ready to capitalize on this growth.?
