Sry I'm late. What influenced you to go with the name brand LED when 3W 365nm LED's go for 10X less on ebay?
The 3 watt LED engine -------Luminous Flux/Radiant Flux: 800 mW
Chinese ebay 3 watt ------------- Luminous Intensity: 50~55mW
And I even tracked down the led manufacturer via Alibaba and the specs are the same
watch the second video in OP it shows the difference.
I needed this light to cure CRL UV 702 and the Chinese one took to long.
