I just put together UV light (had to do something with that bootleg red Convoy S2+) with a 365nm International Outdoors/Mountain (Royalighting RY-3535P) LED. It puts out a lot of visible whitish green light just like this 365nm LED. That International Outdoors/Mountain LED cost more than what we paid for this BLF SE UV light.
I think we got a awesome deal having a dual light made for us like this. You have the 365nm for NDT and to look at currency. Then you have the 395/400nm for looking at biological stains (where the cat peed).
I expect this light to be popular.
