ANSI White (3985K) LUXEON Rebel LED, Mounted on a 23mm Round CoolBase - 400 lm @ 350mA
The SR-08-4000-100 has been discontinued. Our SR-08-4000-403 may be a suitable replacement. We will continue to offer the SR-08-4000-100 until we have no stock left.
Quantity
 
The LEDs on this module can be connected and powered in series or singly for full control of each LED making the SR-08-4000-100 ideally suited for:
  • Flashlights
  • Bicycle Lights
  • Diving Lights
  • Color Tuned Lighting
  • Lightsabers
  • Spot lighting
  • Task Lamps
  • Fiber Optic Illuminators
Need four different color LEDs mounted to this base? We offer a customizable version here.

  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.

Thermal Management

SR-08-4000-100 LED assemblies must be operated to ensure that the junction temperature of the LEDs are kept well below the maximum ratings as specified in the LXM7-PW40 datasheet. A heat sink must always be used when operating this module. The size of the heat sink will depend on the ambient temperature and the current that is used to power the LEDs. Bench testing that we have conducted with a SR-08-WN300 module powered at 700mA in an open air environment and an ambient temperature of 25°C has indicated that a heat sink with a thermal rating of 8 C°/W or lower should be adequate. However, you will need to perform your own testing and analysis to determine if this size of heat sink will be suitable for your application.

The SR-08-4000-100 must be fastened to the heat sink using a thermal interface material such as our pre-cut Bond-Ply 100 pressure sensitive, double sided thermal tape or Arctic Silver thermal adhesive. Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximize heat transfer to the sink. Be careful not to warp or distort the PC Board by over tightening the screws.
