Here is some more information: The electronic ballast comes with the
fixture and is Mfg. or distributed by Tri Con Company. Model # 64009
and advertised as all season, 0 F. to 17.7 degrees C. Requires two F8
tubes @ 32 watts supposedly instant on, no hum, and no flicker. Yes,
all four fixtures are grounded properly.
