the luminaire has reached the end of its service life

In the fourth quarter 2009 VPEC placed its order for multiple additional epitaxial growth reactors making it the single largest purchase of its kind for the company this year. The systems will be commissioned at the LED high bay lighting modern facility in Ping-Jen City, Taoyuan, Taiwan during the second and third quarters of 2010.

Vice President Neil Chen of VPEC said they have been using several AIX 2600 mass production MOCVD reactor systems for some years now. These have contributed greatly to their strong market share for optoelectronic and microwave epiwafers in Taiwan and worldwide.Lithonia says that the luminaire adjusts itself to eliminate the waste of over lighting. Also, the RTLED tracks its own operating hours and provides a visual indicator when the luminaire has reached the end of its service life.

Sunpu-Opto Semiconductor Ltd., a chinese LED fixture maker, is said to be a Cleveland's exclusive supplier of LED streetlights, traffic lights, and fluorescent tube replacements for nearly $10 million. In exchange the company agreed to relocate its North American headquarters to Cleveland, bringing 350 jobs. The City Council had to vote on the deal before the plan was approved. The Cleveland city council voted to delay the vote.

Many of members of the city council expressed concerns that the contract would not be given to a U.S.-based company. At the led high bay light city council meeting, some competitors noted that the lighting contract does not include competitive bidding, which is illegal under the current city charter.
