How do you test a fluorescent light fixture?

Why do my fluorescent lights take a long time to turn on?
If you’re asking why a fluorescent light takes a long time to reach its full brightness, this comes from the ionization of the gas/plasma within the bulb. If it is particularly cold, it will take the gas longer to reach its full conductivity.
