Universal Trigger Start Ballast in F20T12 Striplight
|
I'm in need of some education on these things: Is this HPF? Is it full-power? I'm thinking LPF since an EOL lamp rectifies. I'd say it's about the same size as a LPF F40T12 ballast.
How old is this? I also got the single-lamp version of the fixture and ballast at the same place at the same time.

BTW this above ballast starts fine ungrounded and without the reflector whereas another single lamp one I have hates starting without the reflector! It seems lamps with cathode guards (namely Philips) are more "stubborn" I guess. Anybody have any other theories why?
