LED strip light with battery back-up failure

[LarryFine]

I was sent to trouble-shoot a flickering light in a stock room. It looks like a typical 4' fluorescent strip light, except with LEDs inside a milk-white lens. There is also a red light in the side of the housing, apparently for a battery back-up for egress-lighting purposes. It flashes every three seconds.

My questions are whether the power supply/driver and the battery back-up are a single item, is it replaceable, or are they two separate items, each replaceable, or is the repair to replace the entire light? I don't know whether battery back-up LED drivers and the LEDs are universally compatible.

If it is done the way I do it now the LEDs would be direct drive and the battery backup would be a second item. Keystone makes a good one.

It sounds like someone left the old fluorescent battery backup in place and tried to install LED tubes.

 

[LarryFine]

No, this is not a retrofit. There are no keystones or tubes. The light was LED from the factory.

Sounds like a bad driver then. Prolly end up replacing the fixture.

That's the question: I need to price correcting the issue, and don't know where to start.

LED fixtures are supposed to last 40 years and if they don't you swap them out.

Usually separate units, I take it this is high enough you would need a lift to further troubleshoot it. (I hate trying to troubleshoot from the ground) With the cost of the lift rental, and if you guess wrong.......I just quote the entire assembly, because a second trip and rental would be more costly if you get it wrong. Even then, you have to guess what’s already up there, unless there is a similar fixture down low in a hallway or something.
