I'm retrofitting the T8 fluorescent tube fixtures in my house with direct wire LED tubes. Essentially, the LED tubes come with drivers inside, so I have to remove the fluorescent lamp ballasts from the existing fixture. The LED tubes can be used with both shunted and non-shunted tombstones, as per the specs:
I have had no problem retrofitting my 4-tube fixture. However, my 2-tube fixture is confusing me. The way that it should be wired up is according to this diagram:
I cannot find the ballast for my 2-tube fixture. I removed the cover in the center, and the wiring that was exposed looks like this:
As you might be able to tell from the image above, there are only a few wires in the fixture. Here is one end of the fixture. The blue arrow points to the cord that goes to the wall socket. There is a green wire (which I presume is ground wire), 2 black wires, and a red wire.
So I was trying to find the ballast, and I thought maybe it might be the small white box in the middle, but I have never seen one so small and light. There are no markings on it either, so I could not search up any model numbers online. The white box is connected to one red wire and one black wire.
I tried eliminating the white box and connecting the two sides of the red wire together, and the same for the black, but it doesn't work. Same goes for trying to connect red to black, black to red.
I'm pretty confused at this point. Normally black and red indicate live wires, but seeing as there are no white or yellow wires, I'm guessing one of them has to be the neutral, but I don't know which one. I don't know what the white box does, and I don't know where the ballast is.
