I recently bought some Triton 36inch 30W bulbs that are 1 inch in diameter because they were on sale. I read in a posting that not all 1 inch diameter bulbs are really T8 bulbs, they might be T12's. So the question is: what type of ballast should I use on these Triton's? - 30W T12 with T8 endcaps - 30W T8 with T8 endcaps Thanks S. Wong Irvine, CA wong at dt_wdc.com
