Cree Reveals Revolutionary 60W LED Bulb

Cree says “Thank You Mr. Edison, We’ll Take it From Here”.

Thomas Alva Edison, 131 years ago, was granted a U.S. patent for “Improvement in Electric Lamps and in the method of manufacturing.” Today’s LED lighting revolution heralds the demise of Edison’s 1880, horse-and-buggy era invention.

Cree says it has demonstrated the brightest, most efficient, LED-based A-lamp that can meet ENERGY STAR performance requirements for a 60 watt standard LED bulb. The replacement bulb uses Cree’s TrueWhite LED based remote phosphor technology.

“This is a significant milestone for the industry,” said Chuck Swoboda, Cree chairman and CEO. “In the race to commercialise low-cost, energy-efficient LED bulbs, the industry has forgotten that LED lighting is supposed to look as good as the technology it is replacing. This is the first no compromise replacement for a 60 watt incandescent bulb.”

The prototype bulb is dimmable and emits a, warm incandescent-like colour of 2700 K, with a CRI of at least 90. It delivers more than 800 lumens and consumes fewer than 10 watts. The bulb has been submitted for third party testing to validate the light distribution, lumen maintenance and performance.

“We are committed to leading the market and showing the industry what’s possible with recent innovations in our LED products and technology,” said Swoboda. “We are excited to show the world what it should expect in an LED light bulb and enable our customers’ products with these innovations.”

According to Cree, no commercially available LED A-lamps meet the ENERGY STAR performance requirements for 60 watt standard replacement bulbs at this level of efficiency and light quality.

“This is the first standard LED A-lamp that combines high output with very high efficiency, in a small form factor, without the additional cost and complexity of active cooling or other design compromises,” said Rob Glass, Cree, VP of technology. “We continue to advance our LED technologies to enable our customers’ success and to help accelerate the LED revolution.”
