Lighting Brief: Cree, FZLED, Philips Wins DOE Prize
FZLED has unveiled a range of 22-watt spotlights featuring Cree LEDs. The PAR38-03 series is a simple money-saving plug-and-play replacement for inefficient traditional lights in E27/E26 sockets, FZLED says.
Options include both switch dimmable and non-dimmable versions, with a clear or frosted lens, and with a choice of both a warm white (FZL-PAR38-03-WW-22) and a cool white (FZL-PAR38-03-CW-22) version. The WW-22’s warm 3000K illumination provides 1300 lm with a Color Rendering Index (CRI) of more than 80, while the CW-22 achieves 1500 lm with its bright 6000K beam.
Users of switch dimmable models can cycle the lights through four options: 12%, 25%, 50%, or 100% of full light intensity. All models offer selectable beam angles of 120°, 60°, 40° and 25°.
Meanwhile, Cree has announced commercial availability of its XLamp XT-E Royal Blue LED, optimized for use in remote phosphor lighting and similar applications. The company says the XLamp XT-E LED delivers the industry’s tightest wavelength bins combined with category-leading brightness to simplify remote phosphor designs and lower system costs.
Built using Cree’s Direct Attach LED technology that delivers higher flux, lower forward voltage and lower thermal resistance than other technologies, the XLamp XT-E Royal Blue LED delivers up to 525 mW at 350 mA and 85 C, the company says. The XT-E Royal Blue LED is also available in 2.5 nm wavelength bins to allow customers to achieve desired color consistency.
Cree has also announced a remote phosphor component patent licensing program to enabling lighting fixture companies to develop and introduce products using LEDs such as the XLamp XT-E Royal Blue.
Finally, Philips Lighting has won the 60-watt replacement bulb category of the U.S. Department of Energy’s Bright Tomorrow Lighting Prize (L Prize) competition, which challenged the lighting industry to develop high performance, energy-saving replacements for conventional light bulbs.
The DOE says the Philips LED bulb successfully completed 18 months of intensive field, lab, and product testing to meet the rigorous requirements of the L Prize competition – ensuring that performance, quality, lifetime, cost, and availability meet expectations for widespread adoption and mass manufacturing.
If every 60-watt incandescent bulb in the U.S. was replaced with this 10-watt winner, the nation would save about 35 terawatt-hours of electricity, or $3.9 billion in one year, and avoid 20 million metric tons of carbon emissions, the department says.
The bulb could arrive in stores as soon as early 2012, the department adds.
Last month, Philips’ LED equivalent to the 75-watt incandescent bulb entered the market. The bulb produces 1,100 lumens at 17 watts and is designed to use 80 percent less electricity than traditional bulbs, with a lifespan 25 times longer. It works with traditional fixtures and dimmers.
Cree unveiled its own 60 watt-equivalent, which it described “the first no compromise replacement for a 60 watt incandescent bulb,” in January.
