Led Chip 10W-100W. Radiator required for this type of LEDs.

Attention!

Power LEDs is overheating and overvoltage sensitive devices.

Use good radiator,( S=wattage*20cm2) LEDs produce a lot of warm energy.

Recommended power voltage for 50W is 35V, for 100W is 32V, In this condition lifetime is long.

Also thermal resistance between LED and radiator have to be so possible low.

We are don't respond if LED broken in reason  overheating or overvoltage!

10W: Vf=10-11V, If=1A.

20w: Vf= 32-37V, If=0.5-0.6A

30W: Vf=32-37V, If=0.7-0.9A

50W: Vf=32-37V, If=1.2-1.5A
