ANSI White (3985K) Rebel LED, Pre-Mounted On A 20mm Star Base - 105 lm @ 350mA
The MR-4000-105-20S has been discontinued. Our
CoolBase LED assembly may be a suitable alternative.
Exclusive to Luxeon Star LEDs, this is a single
ANSI White Rebel LED pre-soldered to our
Saber 20mm hex
MCPCB base. The Saber base makes it easy to mount the LED to a suitable heat sink and to work with the LED using standard bench top soldering and hand tools. The MR-4000-105-20S can be ordered in any quantity with quantity discounts available.

LED Part Number
Values based on 350mA and a Thermal Pad temperature of 25C.
Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
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.
Typical thermal resistance from the LED Junction to the bottom of the aluminum base.

Product Videos & Renderings
The Saber 20mm hex base used in this assembly is designed to precisely mount and position a single Carclo 20mm optic over the LED using RTV or optical adhesive. We offer a complete selection of
Carclo lenses here
To fasten this LED assembly to a heat sink we recommend our
pre-cut Bond-Ply 100
pressure sensitive, double sided thermal tape. Pads are cut into a matching 20mm hexagonal shape, making mounting the LED to a heat sink fast and easy.
