Hi Dan

You didn't mention the wattage and pin arrangement that you are looking for. What is it?

If it is for a 65w straight pin bulb? AHSupply.com sells a 55w 7800K straight pin bulb that will work.

All-Glass makes a 55w/65w 8000K straight pin bulb. All-Glass 8000K Full Spectrum PC Lamp 55 Watt at Big Al's Online

You may be able to find some Custom Sealife 8800K 65w and 96w bulbs. These are square pin bulbs.

ADA makes a 36w 8000K bulb that is a square pin bulb.
