I’m looking to get a friend an 18650-powered UV light as a gift within the next week. A Jaxman U1 would be ideal, but the only places I know to get one ship from China. A Convoy S2 UV would be good too. I also have a bunch of S3s, so an emitter on 16mm MCPCB would work fine, or a bare emitter I can flow on to an XP or XM compatible MCPCB. I’d like to get a 20mm filter if I get a bare emitter or a light without one too, if possible.
I know mtnelectronics has a UV emitter, but my impression is that unlike most products they carry, it isn’t a great value.
I just happened to be looking around at UV modules and noticed that they are indeed more expensive than XPL/XML modules. Simon charges about $10 more for an UV S2+ than a XM-L2 S2+. M.E.’s price might be inline with everything else.
