Cree demos 60W-equivalent LED replacement bulb

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has demonstrated what it claims is the brightest, most-efficient, LED-based A-lamp that can meet ENERGY STAR performance requirements for a 60-watt standard LED replacement bulb.

The dimmable prototype bulb emits a warm, incandescent-like color of 2700K, with a color rendering index (CRI) of at least 90. “In the race to commercialize 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,” says chairman & CEO says Chuck Swoboda. “This is the first no-compromise replacement for a 60-watt incandescent bulb.”

The bulb outputs more than 800 lumens while consuming less than 10 watts. No commercially available LED A-lamps yet meet the ENERGY STAR performance requirements for 60-watt standard replacement bulbs at this level of efficiency and light quality, says Cree. Cree attributes the performance to its lighting-class XLamp LEDs, the firm’s TrueWhite Technology, and patented remote-phosphor technology. The bulb has been submitted for third-party testing to validate the light distribution, lumen maintenance and performance.

“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,” says VP of technology Rob Glass.

“We are committed to leading the market and showing the industry what’s possible with recent innovations in our LED products and technology,” says 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.”
