If I may ask two simple (and hopefully not insulting) questions: 1)
are these fixtures properly grounded and 2) do you have the correct
tubes installed?
When you say "electronic fluorescent", I'm taking that to mean these
fixtures are equipped with standard electronic ballasts and not high
output (many "cold weather" fixtures are HO, but in this case they
would likely be fitted with magnetic-core ballasts as opposed to
electronic). If it is a standard electronic ballast, any 32-watt T8
(1 inch) lamp should work -- the older 34-watt or 40-watt T12 lamps
should never be used with this type of fixture.
Cheers,
Paul
