Bought mine at Grainger. Their part number 1C225; $40.95; page 982 of
their 1996 catlogue (catalogue 387). Its a Motorola Ballast with GE
label.See <http://www.mot.com/AECG/MLI/> for a nice wiring diagram. Runs
fine. I made a wooden hood hung on pulleys from the ceiling with
counterweights. Easy up - easy down. Read here that lamps need to be
near metal so I stapled some screening to inside of hood and grounded
it. Wish I'd tried it without this first. My lampholders were from the
same catalogue - eight for a couple of bucks. Have fun and get your
black tape ready!
