  ANSI White (3985K) Rebel LED, Pre-Mounted On A 20mm Star Base - 85 lm @ 350mA
ANSI White (3985K) Rebel LED, Pre-Mounted On A 20mm Star Base - 85 lm @ 350mA
 
Exclusive to Luxeon Star LEDs, this is a singleLXM3-PW51ANSI White Rebel LED pre-soldered to ourSaber 20mm starMCPCB 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-4000-85-20S can be ordered in any quantity with quantity discounts available.

1.Values based on 350mA and a Thermal Pad temperature of 25C.
2.Viewing angle is the off axis angle from lamp centerline where the luminous intensity is 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 the recommended operating current.
5. Typical thermal resistance from the LED Junction to the bottom of the aluminum base.
6.This is the value we recommend you use for determining driver input voltage.

Depreciation Notice: This product has been depreciated (what does this mean?) as our new CoolBase series of FR-4 assemblies offers much improved thermal performance and a lower price. While the MR-4000-85-20S is still in full production and can be ordered in any quantity, we suggest that you consider using the SR-01-4000-85 for new designs.

Important Note About Stock We usually only keep a small number of this assembly in stock. However, we can produce virtually any quantity that you may require on demand. The lead time for larger quantities is typically 2 to 5 business days. Please contact us for lead times for orders above 1,000 pieces. There is no minimum order requirement for this assembly.

Binned LEDsDo you need LEDs with a specific flux, color or forward voltage? Order this LED assembly in 1,000 piece increments and we will build it using LEDs from the same bin. We can also provide specific bin numbers. Contact us for availability.

The MR-4000-85-20S Rebel Star offers:

  • Efficacy of 81 lumens per watt at 350mA
  • A complete selection of compatible 20mm optics & accessories
  • Very long life with 70% of light output after 50,000 hours of operation
  • Can be soldered with standard hand tools
  • No minimum order requirements
  • Lead and mercury free, RoHS and REACH compliancy

The MR-4000-85-20S emits a lambertian beam pattern with a typical viewing angle of 120°. You can further shape the light output of this LED using our selection of secondary optics & accessories.

We recommend that this LED not be powered at more than 350mA unless special precautions are taken to ensure that the LED is properly cooled at higher driver currents. We offer a complete selection of current regulating drivers.
