LED Direct Replacement Tubes

[jmellc]

I've installed a lot of LED bypass tubes but never worked with direct replacement type that use the original fixture ballast. Would they work in emergency lights with battery backup? Has anyone used these?

LED tubes powered by a flourescent ballast?
They make such a thing?

I can't recall ever installing the LED tubes that used the fluorescent ballasts (Type A) -- just the bypass ones (Type B).
They do make hybrid LED tubes (A+B) that will work with the ballast or bypassed (don't ask me how). They also make LED tubes that have their own integral backup. I have a feeling you'd have to consult a manufacturer to know whether a certain LED would work with an emergency ballast.

The Type A replacement tubes I have seen only work with electronic ballast. I don't remember any other restrictions in the instruction sheets.

Yes, but they don’t last as long as the direct wire.

Someone asked about that earlier this year, but I don’t remember the response.

I have the same question as I have been asked if the emergency tubes could be LED.
