    500 Watt enlarger bulb?

    Does anyone know if this would work for a condenser enlarger? (For Saltzman 8x10). Mogul base converter available.

    It is so reasonably priced I can buy and try, but I thought I'd ask the net wisdom.

    The bulb here: https://www.1000bulbs.com/product/284/IN-0500PS35F.html

    I don't know, but I ordered 1 with Satco adapter. It may be useful in several ways here.

    Also notice the CFL equivalent is almost as powerful.

    Do you think it is a typo?

    As long as its frosted enough, I don't see why not. The mogul adapter will change the position of the bulb slightly but not much.

    No, it's a 130 volt bulb for USA 120 volt, so 2000 life hours may be possible and it seems users are large rooms with high ceilings like a Church. They want long life bulbs.

    However it does need venting, or it's going to be an electric heater. Venting on an Elwood is minimal and I may add an exhaust fan.

    I will try it. Focus fast, turn it off, let it all cool down and of course use double glass neg carrier.

    I had a line on 2 big Durst condensers at Central Camera but the shop meddled the middle and they disappeared.

    If it doesn't work for me, it will be great for lighting effects.

    I have a few long neck 250 and 500 watt enlarger bulbs, they don't last long.

    This bulb is long but the neck looks kinda short for the Saltzman adjusting system, which is a collar around the bulb's neck.

    Gotta buy it and try it.

    Gotta see how bad the writing is on the bulb top. Sometimes it can be scraped or sanded off.

    Seems like a few options, found this one.

    So do you think a certain version of the adapter would be necessary because of the high wattage bulb? Or should they all work just fine?

    The adapter shouldn't interfere with the bulb position since the connector is floating anyway.

    Re: 500 Watt enlarger bulb?

    At 2000hr life, it is probably going to be less bright than a 250W enlarger bulb, but much hotter - this could be a danger for your negatives. I don't know by how much the bulb can be moved in that enlarger, but the difference in filament position between the original and replacement bulb (including all adapters needed and any size difference) MUST be small enough that the filament can be repositioned into the condenser focus, or it will not do.

    I use standard-base 500W ECT bulbs in my hot-lights. The frosting gets black after a while, even though the filament still works fine for many hours.
