I build lights using the LG 365nm parts. Big problem during burn-in; ladybugs, stinkbugs, and any random moths just end up crawling around (I have dozens powered on at a time). Can’t open the door without some critter flying in.

I’ve tested these types of lights (not this seller, not necessarily this brand) and they put out a very floody beam at 365nm - cheap too, already built:
