Most likely the lamps are t12 fluorescent bulbs. Which are still being sold at Lowes, Home Depot, Ace Hardware... And on the 'net...
But, know that they are not being made anymore...
The next question is; Are the lamps you are needing, single pin, nipple or dual pin? And also you are going to need a size...
I use Yahoo search, and typed in; t12 fluorescent bulbs and clicked on images and you will see the different "pin" configurations and should be able to tell which one you need...
Hope this helps...
