EETimes.com – Cree white LED produces 131 lumens per watt — FYI
MANHASSET, N.Y. — Cree Inc. said it has produced a white LED with efficiency of 131 lumens per watt, confirmed by the National Institute of Standards and Technology.
“This is the highest level of efficacy that has been publicly reported for a white LED and raises the bar for the LED industry,” said Scott Schwab, Cree general manager, LED chips, in a statement.
Semiconductor suppliers have racing to produce higher efficiency white LEDs as the industry seeks energy-efficient alternatives to conventional lighting. In March, Japan-based Nichia Corp. reported it had developed a white LED rated 100 lumens per watt.
Last September, Cree (Durham, N.C.) said its white XLamp 7090 Power LED was capable of producing 86 lumens per watt.
Lumens-per-watt is the standard used by the lighting industry to measure the conversion of electrical energy to light. As a reference, conventional incandescent light bulbs are typically in the 10 to 20 lumens per watt range, while compact fluorescent lamps range from 50 to 60 lumens per watt.
Lower the cost of LED technolgy in the US and it will evolve over night.
Why is the mark up in the states so high compaired to the overseas prices of LED components?
Because its new to the U.S., GREED inflaits the price and slows the progress as usual!!!!
Doh! I was domain name shopping at namecheap.com and went to type in the domain name: http://www.dvorak.org/blog/2006/06/21/new-record-for-led-lumens-per-watt-the-end-is-near and guess who already acquired it? You did! lol j/k. I was about to shop for this domain name but realized it had been taken so I decided I’d come check it out. Good blog!
