So... If anyone on the list has a favorite source for VHO bulbs, would you pass along the information? The best I can do at my local electrical supply is to order a case of 30, which is just a bit drastic for me at this time. The price they are quoting me for 50/50 sylvania bulbs is $21.95 each. That sounded high for case price. But the ballast price is only $91.00, which I did like the sound of. Marci
