Quarter-watt LEDs from Cree for distributed lighting applications

Cree, Inc. has announced the commercial availability of the XLamp ML-B LED, quarter-watt rated LED targeting distributed lighting applications such as panel lights and LED-light replacement for fluorescent tubes.

Cree says lighting manufacturers have tried to achieve a uniform lighting appearance by placing many low-power LEDs in close proximity under a diffuser.The accidental experiment came just weeks before the county led tube council is set to publish a new report on the future of the square. This use of typical low-power LEDs will not enable manufacturers to meet rigorous ENERGY STAR requirements or customers' expectations. According to Cree its ML-B LEDs are designed to last 50,000 hours and to provide the lighting-class levels of efficacy, thermal resistance and reliability that can enable ENERGY STAR-qualified fixtures.

"The innovative ML-B LED delivers lighting-class performance with the smooth,A built-in dock is attached to the battery and when LED lighting supplier not in use folds up in a nice compact manner to about half the size of the iPhone itself. uniform appearance that lighting manufacturers want for distributed lighting applications," said Paul Thieken,A team of scientists led by John Badding, a professor of chemistry at Penn マジコンds State, has developed the very first optical fiber made with a core of zinc selenide -- a light-yellow compound that can be used as a semiconductor.

The XLamp ML-B LED delivers luminous flux up to 30 lm at 80 mA in cool white (5000 K) and up to 24 lm in warm white (3000 K).

XLamp ML-B LEDs are available now in sample and production quantities.
