Hi Debbie, The power may need to be turned off to the fixture, then back on again (please see the wiring diagram at: http://www.aleddra.com/spec/CutSheet-Emergency-T8-Tube.pdf). If the bulb still isn't working correctly, please reach out to us at 888-455-2800, option 4 and one of our reps can assist you further.
The lamp says Before installation turn power off. What happens if power is on?
This can cause the bulb to malfunction, become defective and can create a safety issue.
I could use a wiring diagram.
Would the battery turn on the light every time you turn of the switch to the fixture? OR is it like the Sengled bulbs which sense if it is a switch you've turned off or the power itself has gone out?
The battery back up will only work when full power has been cut. This bulb will not light just because the switch was turned off.
