We have 3 fluorescent light fixtures in our office and each of them has 2 tubes. All 3 fixtures are battery backed up versions with a red light that you can press to test the light.
The strange thing is that none of the light fixtures is working, but the red light is ON. And if we press the red light, the lights will come on as long as we keep the finger on the red light. But as soon as we release the red light, the light fixture will go dark.
Any idea?
