I recently took an old ballast I had lying around and installed it as a shop light over my desk. I took an extension cord and stripped the wires and connected all the whites, all the blacks, and attached the ground to the metal fixture itself. I then wired in a switch and plugged it into an outlet.
When I turn the fixture on, the CFL tubes glow a dull orange at each end and will only fully illuminate when I physically touch the fixture and essentially ground it. What did I do wrong?
Note, this doesn't happen all the time. If the fixture has been on for a while and I turn it off and turn it back on, it does so fine w/o me needing to touch it.
