| CREE gets to 100 lumens/watt for warm white light |
| 2007-09-19 |
| DURHAM, N.C., Sept. 13, 2007 (PRIME NEWSWIRE) -- Cree, Inc. (NasdaqGS:CREE - News), a leader in LED lighting components, today announced it has achieved R&D results of 129 lumens per watt for a cool-white LED [cool-white is about as good as the sucky pre-T2 fluorescent bulbs)]and 99 lumens per watt for a warm-white LED [compared to 10-25 lumens/watt for incandescent]. These are the best results reported for packaged, high-power LEDs... The results have been verified by the National Institute of Standards and Technology (NIST). [- full disclosure: my family owns a good bit of stock in this company; rumors of a GE purchase of CREE bounce around every so often; unfortunately CREE's progress in technology isn't matched by their performance in sales - the past 3 or so quarters have been less than expected] |

| #4 problem for CREE has been production volume. THeir process apparently has had yeild issues in the past, meaning its hard to make those 100-lum/w LEDs in any quantity with quality (i.e. you run a batch of 1000, and you only get 17 successful LEDs out of it). |

| #3 3dc CREE has purchased a manufacturing company (COTCO in Hong Kong). Speculation is that they are reconfiguring for production of retail products but it is speculation at this point. CREE Stock is up 7% as of a few minutes ago. Maybe a bunch of brokers on Wall Street read Rantburg. |

| #2 CREE primarily sells to equipment manufacturers, not end consumers. At least they did when I used to track them. |

| #1 What do their bulbs sell for? Do Home Depot, Loews, Target and Walmart plan to stock them? |
