Electrical – wire this three wire fixture to the two wire junction box

electricallightingwiring

I have this three wire LED motion sensing outdoor fixture (labeled grnd, Neutral, Black) Outdoor light bracket

And I’d like to wire it to my current junction box which has only two wires, red (!!!) and white. Is this possible? It’s replacing my old fixture which actually was a three wire incandescent, which just used two:

Old fixture, black here actually feeds into red outside

Is this doable? The garage actually has three wire wiring, just this box doesn’t. I could do the old college try (it’s cheap enough that if i fry it i won’t cry) but i want to do the right thing.

EDIT the junction box. Notice there’s a bolt hole labeled GRD. I have no idea if it’s actually Ground junction box, with GRD Labeled bolt hole

What you show in pic 2 is the fixture. Looks like black and white are wired to the outlet box. (Red is the switched feed from detector to lights).

If there is a bare copper wire in your junction box, it should be connected to the green wired terminal.

Please include a picture of the junction box in your question. Then we'll know for sure.
