Hey, were those on a 2 inch pipe or a smaller one?

The older Westinghouse cobraheads had a special adaptor in the slipfitter to allow it to fit in 1 1/4 inch pipe. I am looking for one of those adaptors for my OV-14B which uses same adapter as flat bottoms...I also believe the 2nd generation OV-25 had the same thing, not sure though.

Nice light, does it have the original 240 volt ballast or a metal halide one?

It could also have orginal 120 volt MV ballast......they did come with those.....my OV-14B ballast is a 120 x 240 volt so it can do 120 or 240 volt

This had the original ballast, I connected it to 240v. I gave this and another to Dave. These are the ones that were dropped and broke the glass.

Jace, the first and second generation OV25s used a bolt-on adapter for 1 1/4-1 1/2" pipe.

I know that, you ntold me that long ago, I am looking for the adaptor....that's kinda why I asked

Be mindful though that the two generations are not interchangeable. You have to get one off of a first generation Silverliner.
