The MR-4000-105-20T has been discontinued. Our SR-03-4000-100 CoolBase LED assembly may be a suitable alternative.

Exclusive to Luxeon Star LEDs, three LXML-PW51 ANSI White Rebel LEDs are pre-soldered to our Saber 20mm Tri LED hex MCPCB base. The Saber base makes it easy to mount the LEDs to a suitable heat sink and to work with the LEDs using standard bench top soldering and hand tools. The LEDs can be powered in either parallel (single) or series (triple). The MR-4000-105-20T can be ordered in any quantity with quantity discounts available.

Need to be able to mount three different color LEDs to the same base? We also offer a customizable version of this LED assembly here.

LXML-PW51		LED Part Number
1. Values based on 350mA and a Thermal Pad temperature of 25C. 2. LEDs connected in series. 3. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value. 4. This is the maximum operating current that we recommend for this LED. Higher drive currents are possible, but requires careful design of a suitable cooling system. 5. Typical thermal resistance from the LED Junction to the bottom of the aluminum base.
