Review by Jxxxe (US)
I purchased 3 100w pure white units. I tested these units for optical flux output and element consistency. Parts of all elements begin to emit at 22.2 volts. All emitters were fully emitting at 22.8 volts. This is a differential of only .6 volts. A 30w LED of the same running voltage from a different manufacturer started emitting at 24.6 volts and did not begin to fully emit from all emitters until 28.4 volts was applied. Now the interesting part. At full specified current the weak elements of 30 watt LED never caught up in brightness to the emitters that began to emit at the lowest voltage. The Chanzon LED emitter elements were all almost identical in output at full power just as at lower voltage. So it would seem that what you see at low voltage carries on to full power performance. The Chanzon emitters were brighter than any of the 30w emitters at full power. All three Chanzon LEDs performed identically.

what's the CRI of 100 watt led?

very powerfull and bright
