Which two green wires do I connect?

[douirc]

Hi. My old Hayward LED had only two wires and my new J&J has three.

My J box has three green wires inside, one that comes from the pool niche, one that comes from the 120v -> 12v transformer and one that comes from the lamp itself.

Which of the two wires do I connect the lamp green wire to? Niche or transformer?

Thank you!

The blue/white/green are coming from my transformer. I connected the blue to black and white to white. maybe I just connect green to green and leave the niche green alone. that would probably make sense. that correct?

now that I look at this more, I'm not sure what the left hole is. the right is clearly the wires from the transformer (blue/white/green) and the center is the lamp cord (black) and niche ground (green). there is a bare wire in the left hole and not sure where it's going lol

All of the green wires and the junction box need to be tied together electrically. Looks like the separate green from the central conduit was originally tied to the screw below? If so i would put that back. strip the end off the "pig tail" coming off the screw on the upper right and wire-nut the green in the new light cord to that.

I would guess that the conduit on the left either goes another, no longer used, light niche, or maybe someone planned to add garden lighting?

perfect, thank you! that's what made most sense to me.
