    Light bulb question

    I'm putting this in miscellaneous 'cause it's a darkroom related question, but a mod may move it if they think it fits better elsewhere.
    I have a regular light in my darkroom that just blew the other day. It was a 100W one and I don't have any more and can't get one. Of the brighter replacements out there, which ones turn off the fastest and how long do they take? The boxes only mention if they turn on instantly. I don't really want to stand around for 10 minutes to wait for the light to be completely off. I tried using a 60W, but it isn't really bright enough 'cause it has to cover the whole room.

    You talking about compact fluorescent (CF) bulbs not regular tungsten bulbs, right?

    Use two 60-watt bulbs

    You may be able to find some "special use" incandescents that are not prohibited under the new rules. Outdoor floods, "rough duty" lights for mechanics, etc.

    I had same problem. What was a 100-watt halogen before, I replaced with a 72-watt Halogen Reveal bulb.

    I would use two 60Ws, but there's only one socket.
    Yes, I can't buy incandescents in 100W, so looking at the halogens, LEDs, and whatever else they have at Lowes/Home Despot. I just can't tell which ones will turn off quickly and not expose my film if I'm loading holders, etc...

    The halogens and LEDs will be fine - they don't illuminate after they are turned off.

    Fluorescents are potentially the source of problems.

    Check out 100W "rough service" bulbs on that well known auction site. Same old incandescents, repackaged.

    If I can't find some "rough service" 100W ones, that might work. I may try some LEDs first.
    Thanks!

    Tom, are those non-smiley faces your opinion on the whole light bulb thing? Mine, too. But I think we're all preaching to the choir here on that one.
