Hey William,
Nice to see you on the boards. I hardly check up on the FMBB, so I haven't "seen" you in a while.
There's a couple of other manufacturers that make UV cured finishes. The brand that we use has a line of products, but they don't carry them locally. The salesman would have to go to a special training class somewhere on the mainland, so he said they don't plan on carrying them any time soon. There were also a couple of other brands, but I can't remember what they were. I don't know about the bulb makers. I do know that the wavelength is specific, but no one would tell me what it is. I'm sure they keep it secret on purpose, to discourage people from buying elsewhere. As for the wavelength between brands, I would assume they're close.
