enlarger light bulb

so i recently acquired a omega c700 enlarger. it has been working for about 4 days but the light bulb went out. i can order a replacement bulb from b&h but it wont ship for a week or two. i dont have that kind of time. i tried using a 20 watt fluorescent bulb, which is equal to a 75 watt bulb, but it through off my timing. i guess it would brighten up as it stayed on longer and cool down as it was off giving in consistent results. i could manage but it is kinda of annoying. my question is, before i head out to lowes or home depot, do local hardware stores offer a light bulb i could use or do you have any other recommendations.

thanks
jorge

The fluorescent bulbs are not a good solution because they are slow to come to full luminance. They also continue to glow after they are turned off. A tungsten incandescent is the better bet. The lamp for your enlarger may be a special "teardrop" shape designed to provide even illumination with the condenser. So the short story is to get the appropriate replacement from Adorama, B&H, or Omega and use a regular 75w bulb in the interim.

BTW...If it takes the PH140 bulb, Adorama has it in stock and will ship for for free. Buy two as insurance...

I have an Omega C700. It's a terrific compact enlarger.
Here's the replacement bulb you're looking for: PH140 lamp

It's a good idea to have a spare. A burned out bulb can ruin a printing session.
You could try a standard 75W soft white incandescent bulb until you get the original.
