Lumileds boosts output of Luxeon round


Output and efficacy have increased by 14 percent to 693 lumens and 178 lumens per Watt at 4000K and 70CRI

Lumileds has increased the light output and efficacy of its Luxeon 5050 Round LED.

First introduced in October 2016, this LED's output and efficacy have increased by 14 percent to 693 lumens and 178 lumens per Watt at 4000K and 70CRI. Further, the portfolio has grown in breadth and is the only 5050 offering with a full array of CCT options at 70, 80, and 90 CRI, according to Lumileds.

“Sometimes the most obvious element is ignored even though it’s the most important factor for a system,” said Mei Yi, product manager. “A round light emitting surface is critically important if you want to achieve a symmetrical light distribution with pleasing uniformity and smooth transitions without jeopardizing optical efficiency, lens design complexity, and cost.”

The LM80 report for Luxeon 5050 covers 17,000 hours of testing, and Lumileds provides customers with a comprehensive and detailed analysis of 16 different test items including: High Temperature Operating Life, Hydrogen Sulfide Test (15ppm H2S, 40C, RH 80 percent), and Temperature Cycle. Lumileds also reports detailed flux, forward voltage, and color maintenance data. Lumileds extensive testing of Luxeon 5050 Round allows it to confidently claim L70 and L90 above 100,000 hours.

The performance, efficacy, and reliability of Luxeon 5050 Round (24V and 6V) and the fact that it’s available in the full range of CCTs and CRIs mean that this LED is equally at home in indoor and outdoor applications where the quality of light, sustainability, and cost-effectiveness are driving design factors.

Luxeon 5050 Round is available through Lumileds global distribution network.
