Thanks for the link Hoovercat. The bulb that I would need from there looks to be this one
Couple more questions though.
1. The bulbs that are currently in the fixture are only 9" long while the one at the LightBulbDepot is 10.8" long. I've measured and I think that I could squeeze this bulb into the fixture, but I'm concerned that it would be too close to the wiring and plastic enclosure ends. Should I be concerned?
2. Has anyone ordered from LightBulbDepot, and how was the experience?
