Don.....I have a 4 bulb t5 retro....needs a end cap or two. 36" length. New bulbs.
Also have a 250w halide in a parabolic fixture with electronic ballast.
Also have a small 150w halide with standard ballast and a spare ballast, not pretty but it's works good. Was a coralife clamp on that the arm broke, made a conversion to hang it.
I will be heading down to Dayton this afternoon, so I need to know in short order.
