Red (627nm) LUXEON Rebel LED; Mounted on a 20mm Tri-Star CoolBase - 318 lm @ 700mA

Red (627nm) LUXEON Rebel LED; Mounted on a 20mm Tri-Star CoolBase - 318 lm @ 700mA

Not recommended for new designs.

The SR-03-D2050 LED assembly has 3 LXM2-PD01-0050 Red LUXEON Rebel LEDs soldered to our 20mm Tri-Star CoolBase. The FR4 CoolBase offers a high efficiency thermal design that matches or outperforms* standard aluminium MCPCB bases.

  1. Values based on 350mA and a Thermal Pad temperature of 25 °C.
  2. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
  3. This is the maximum operating current that we recommend for this LED. Higher drive currents may be possible, but will require careful design of a suitable cooling system.
  4. At 350mA.
  5. Typical thermal resistance from the LED Junction to the bottom of the FR4 board.
  6. This is the value we recommend you use for determining driver input voltage.
* Results will vary depending on the quality of the dielectric material used in the MCPCB base.
