Halide Bulb/ Ballast information

[RobbAdams]

Ballast bulb information.

Is there somewhere I could find a list of ballast types with explanations?

Eg- m58 a xxxwatt ballast Magnetinc/Electronic Pulse/probe start designed to fire Blah blah type bulb?

My wife said they have a bunch of extra ballasts from electrical contracting jobs that are baisically taking up room in their workshop. The purchaser said I could get what ever I wanted at a steal, so I need something to sort through all this with!
