LightSpeed 2046B-RT Rapid Start Ballast in my CH-30 Reptile Fixture
This is in the fixture I bought at a thrift store not knowing what it was for at the time (I thought it was a multi purpose shop light)
Anyway is the F20T12 lamp that it takes an easy to find lamp or is it a special purpose lamp?

Interesting how it can acceot such a wide range of lamp wattages. Is this some kind of electronic ballast? The F20T12 is a standard lamp, you should be able to find it easily.

Looks like the F20T12 and the F15T8 would burn at full brightness while the F40T12 and the F34T12 would be underdriven, and so are not suitable for this ballast.
The American fluorescent ballasts, tends to accept also lamps that won't work correctly on them. a F40T12 ballast for example isn't suitable for F20T12 and F15T8, and such is the opposite.

It also seems to me that the "HPF", "NPF" and "LPF", are essentially BS... HPF have high ballast factor, and NPF and LPS have low ballast factor. All of them have low power factor if the PFC capacitor isn't there, or high, if the PFC capacitor is there.

@dor123: HPF stands for high power factor. All HPF ballasts have a PFC capacitor. NPF stands normal power factor and LPF stands for low power factor. NPF and LPF ballasts do not have a PFC capacitor. Ballast factor is a seperate concept, it just so happens that a lot of NPF/LPF ballasts also have a low ballast factor.
