Cree launches highest performance warm and neutral white lighting-class LEDs
DURHAM, USA: Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announced the commercial availability of XLamp® XM-L LEDs in neutral and warm white color temperatures (2600K – 5000K CCT). Cree once again leads the industry by extending the XM-L LED family’s unprecedented light output and efficacy to a wide range of mainstream indoor and outdoor lighting applications.
The XM-L LEDs deliver unmatched performance across a wide range of drive currents. Warm white (3000 K) XLamp XM-L LEDs provide up to 113 lumens and 117 lumens per watt and neutral white (4000K) XM-L LEDs provide up to 134 lumens and 138 lumens per watt, both at 350 mA. At 700 mA, warm white (3000 K) XLamp XM-L LEDs provide up to 220 lumens and 108 lumens per watt and neutral white (4000K) XM-L LEDs provide up to 260 lumens and 128 lumens per watt. Driven at 3.0 A, XM-L neutral white LEDs produce 850 lumens at 84 lumens per watt.
Unlike competing LED solutions that use large footprint packages and diffuse optical sources to deliver hundreds of lumens, XM-L LEDs provide breakthrough performance in a compact footprint and small optical source size. This high lumen-density can simplify designs and reduce costs for lighting manufacturers building products for directional lighting applications, such as high bay, parking, roadway, track, spot and LED replacement lamps. XLamp XM-L LEDs enable manufacturers to easily control the light output and place light exactly where it is required, minimizing wasted light and light trespass.
Cree expands broadest portfolio of lighting-class LEDs optimized for distributed illumination
DURHAM, USA: Cree Inc. has announced the commercial availability of the XLamp ML-B LED. Designed for quarter-watt operation, the XLamp ML-B LED brings lighting-class performance to distributed lighting applications where the light source is visible, such as panel lights and LED-based fluorescent tube replacements.
Lighting manufacturers have tried to achieve a uniform lighting appearance by placing many low-power LEDs in close proximity under a diffuser. This use of typical low-power LEDs will not enable manufacturers to meet rigorous ENERGY STAR requirements or customer's expectations. In contrast, Cree 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, uniform appearance that lighting manufacturers want for distributed lighting applications,” said Paul Thieken, Cree director of marketing, LED components. “The ML-B LED provides the right balance of lumen output, footprint, efficacy and value for direct-view lighting.”
Cree XLamp MT-G LED delivers unprecedented performance
DURHAM, USA: Cree Inc. announced a new lighting-class LED designed for high-output, small form-factor directional lighting applications.
The XLamp MT-G LEDs are optimized for 35-50 Watt halogen MR16 retrofit bulbs and other accent, track, display and down lighting used in retail stores, residential settings, museums, art galleries, hospitality and landscapes and are the first commercial LEDs to deliver sufficient light output for these applications.
The multi-die XLamp MT-G LED features Cree EasyWhite technology to deliver consistent color in a small, highly efficient package. This innovative LED is designed for the high-lumen, small-footprint requirements of 35 and 50 Watt halogen retrofit lamps. Cree engaged driver, thermal and optic providers to create an MR16 lamp reference design to further enable its LED customers to quickly address this market. The reference design is available for free at mtg.cree.com.
“To date, there are no energy-efficient alternatives for many high-lumen, small form-factor, directional lighting applications. Until now, LED-based MR16 lamps have been a tremendous challenge for the lighting design community in terms of both light output and color consistency due to their small size and limited capacity for thermal management,” said Paul Thieken, Cree, director of marketing, LED components. “Cree developed this LED from the ground-up with applications like these in mind, and its introduction signals the arrival of the LED lighting revolution in these high-profile markets.”
