Would you be able to help be debug a curious issue with a dual circline light fixture (12"/32W, 8"/22W) and a TLE54 ballast?
I needed to replace both bulbs. Once I did that, flipping the switch to on results in the lights briefly lighting up for a fraction of a second, and then going dark.
By experimentation I found out that if I connect only one of the two lights, then flipping the switch to ON position will turn the light on and the light will remain on. This is true for both the 12" and the 8" bulb: if I connect only one of them, no matter which one, the fixture works. But the two won't stay on if connected at the same time to TLE54.
The ballast used to be able to drive both bulbs. What is going on, and what do you think I can do to have a fixture in which both bulbs work?
