3x LUXEON V 4000K – 5700K 70CRI LED on 20mm 3xV mosX MCPCB with MOSFET+NTC+wires (wires not soldered) – clearance sale

14.50 7.25


  • First 4mm^2 die LED from Lumileds
  • Extremely low forward voltage: long run-times on high currents with stable brightness when used with CC linear drivers, easy to achieve high drive currents
  • Highest “factory” max. drive current among 4mm^2 LEDs: 5,0 Amps
  • Record-low thermal resistance of 0.8C/W : ~3 times lower compared to other 4mm^2 die leds ( XP-L 2.2C/W, SST-40 2.5C/W) – lower chip temperature, better efficiency and lumen output at high drive currents
  • Superior tint quality and beam uniformity compared to CREE LEDs
  • Part number(CCT 5700K): L1V1-577003V500000
  • Part number(CCT 4000K): L1V1-407003V500000
  • CRI: 70min.
  • Flux bin (5700K) : W (570 – 600lm)
  • Flux bin (4000K) : V (540 – 570lm)
  • Vf bin :                   F (2.65V-2.85V)
  • Soldered ( Pb-free SnAgCu solder) on L4P 3xV 20mm mosX MCPCB
  • Compatible with Carclo triple 105xx optics (tight fit)

Note 1: this PCB has all components required for use with LD-B4 driver.

Note 2: Due to very high thermal conductivity on whole board area, soldering wires is more challenging; one simple solution is to preheat PCB with hot air or with soldering iron (by holding iron tip on + or – pad) and then solder wires. During soldering, PCB must be thermally insulated(piece of thick paper is good enough) from any thermally conductive objects.
