That's hard to measure since I use rubber end caps - it's hard to get to the 
bulb pins. But I use plain, old-fashioned tar ballasts made by Advance that 
produce loads of heat (i.e., energy loss).  It would be nice to go to energy 
efficient T-8 bulbs and electronic ballasts (and don't think I haven't thought 
about it) but there is all the work involved in getting parts and finding the 
right bulbs and constructing the whole thing. besides, what I have now is just 
enough <g>.
