I’ve been looking for this link for a while but just found it… It’s a test Djozz did a couple of years ago, with UV transmission through different materials…
…The PC Carclo optic seems to be opaque to UV…
I was able to build a fairly floody UV light using a junk triple host that had individual reflectors for each 3535 emitter, with glass lenses, but having the 7070 emitter would be more difficult on a budget…
Not sure about the emitters you are using, but if we could find something like the G36 triple to use as a host:
…with some OP reflectors, it might make a nice floody light… A triple 7070 UV flood-monster. With some UV-pass filter lenses. Do NOT take into the hotel with you… :zipper_mouth_face:
