how to tell if a cree cxb3590 is genuine or not.

I purchased a 5000k cxb3590 from rapidleds and its here. I’ll take a close up photo of the front and back and lets hear if its a good one or not :slight_smile: going to replace the cheap chinese 100 watt led in my flashlight build I have.

sorry I cant get it to show up in the post…

I guess since no one replied, no one knows if this might be a genuine cree led module. I can take a better photo of the led with my dslr if its needed. the heatsink I was going to use might not be suitable for this, so I cant test it as of yet.

Power it up and see the output. According to VOB real Cree vs Chinese cob isn’t even a comparison, you shouldn’t have any problems knowing if it’s genuine after the first moment you power it up!

thanks for the reply, like I said the heatsink I have might not be suitable. I might need a small copper plate to use it, trying to find another one, but they seem to be rare in the size I need for this project.
