Trouble With Blacklights

    I've tried multiple blacklight bulbs and they're all emitting a lot of blue -- are there any out there that only emit up to the violet range or better yet, emit no visible light at all? (Bulbs, not the fluorescent tube).

    I know that Jack has a few but I don't know which ones he's using.

    Which ones have you used? Did you measure the blue emitted?

    Hmm I use the Sunlite bulb and haven't had any issues. I'm not sure they emit blue in the range that would be disruptive to melatonin. I could be wrong though.

    Ya you guys gotta get a spectrometer. You can buy one that photographers use to find out for sure. Until I get one im not using mine after sunset. Jack is using a brand sold at battery and bulbs in the US. These are not avalable for Kris and I because were canucks.

    Thanks Kris, do you know which ones?

    I found these: https://www.batteriesplus.com/productdetails/cfl10858

    -- The other way to do it is with polyethylene filters for the purple range and use incandescents, theater lighting companies have these but I'd rather do the blacklight, though that may change.
