Insides of the cooper OVZ 100w MV

Here you see the OV-15 ballast, and the lamp and stuff.

As you see here I used the terminal board FROM the OV-15, which fit on the terminal block holder very nicely.

I also used the photocell socket from the OV-15, mostly because the other one made it impossible to plug in different wires.

But everything fit in nicely. As you see here.

Sorry for the foul quality grainy picture, it's like that because my mom's camera, which I use to take all my pictures, is missing, so I used my iPod camera.
