LEDs for white light now at 57 lumens per watt
Full disclosure - I own stock in the company that makes this stuffThursday February 16, 9:00 am ET DURHAM, N.C., Feb. 16 /PRNewswire-FirstCall/ -- Cree, Inc. (Nasdaq: CREE - News), a leader in LED solid-state lighting components, today announced general availability of the industry's highest efficacy white power LEDs at 350 mA. Cree's white XLamp® 7090 power LED package achieves a typical efficacy of 47 lumens per watt at a drive current of 350 mA, and 57 lumens [per watt] of typical light output. Florescents are about 40-70 lumens per watt but they are ugly and it is hard to do decorator stuff. Also, LEDs could potentially reach 120 lumens/watt. The newest product will probably be installed in new homes in California (where regs mandate energy efficiency). LEDs are already used in autos and on computers and phones. If the 120 figure is reached, it will justify massive replacement of ordinary bulbs and save oodles and oodles of kw capacity. Posted by: mhw 2006-02-17 |
