The Luxeon® K LED is a high power array style LED. Our stock includes the warm-white 2700K CCT with an emitter count of either 8 or 12, however the Luxeon offers emitter counts from 3 to 24. Note: we will special order upon request. The Luxeon K produces high flux at high efficacy in a small and easy-to-use package. This high lumen density enables lighting applications in thermally and space constrained systems. Like all Luxeon products, the Luxeon K ecosystem in extensive and is built with quality materials and components that give lighting designs the product they need to match a wide variety of lighting applications.

    Important Information

    Average Lumen Maintenance Characteristics Lumen maintenance for solid-state lighting devices (LEDs) is typically defined in terms of the percentage of initial light output remaining after a specified period of time. Lumileds projects that LUXEON K products will deliver, on average, 70% lumen maintenance (L70) at 50,000 hours of operation at a forward current of up to 700mA. This projection is based on constant current operation with junction temperature maintained at or below 125°C. This performance is based on independent test data, Lumileds historical data from tests run on similar material systems, and internal LUXEON reliability testing. Observation of design limits included in this data sheet is required in order to achieve this projected lumen maintenance.

    Incredibly Bright
    Wow! I can't believe how much light you can get out of such a small package. The Warm-White color is really nice, much better than the blueish tint of some other high powered LEDs. I wasn't sure if I could drive this LED with my 12v system. I called and talked to someone at LEDSupply and they suggested the 700mA FlexBlock driver becasue it can boost the output voltage. My setup works perfectly and the dimming option on the FlexBlock is really handy.
