Light electronics question



I've experienced a variety of problems with florescent lights in the past
few months and would like to know the cause and ways to correct the problem.
These problems refer to rapid start lamps. Types of problems:

1. Turn on the switch, lamps glow faint orange at the ends but do not come
on. They come on after a few minutes (times vary and unpredictable) by
themselves.

2. Turn on the switch, nothing happens. Twist the bulb slightly and it comes
on and lights fine.

3. Turn on the switch, nothing happens. Touch or tap the metal hood and the
lamp comes on and lights fine. This only happens with a T-8 Triton bulb.
Regular T-12 bulb works fine.

Thanks for your attention.
