The OV-25 sure has a very neat shape!

I will pretty much need a refractor for this. Since it came without one. Any idea where I could get one?

And the refractor on this in this picture is the OVM one.

Cooper... They still make the OV-25 refractor.

That would be expensive. I guess I will have to wait until someone has an extra refractor laying around.

Hmm. You may be able to find one on ebay or such.

Nice light Ian.

I can't figure out how to take the door off the hinge on this either. It won't come off just like the OV-15.

Nice catch Ian!

What is the secret to taking these doors off? I can't figure it out... It seems mine is stuck on the hinge.

Hmm. I know on mine, you open the door and slide the door to the side to get it off the fixture. These hinges look different though...

The doors on cobraheads are usually easier to get off when they are facing down. On my OV-25, the door has to be swung almost all the way back (toward the pole and parallel to the ground, with the lens facing toward the sky, if it were mounted,) to allow it to be removed from the hinge. I presume this was to keep the heavy door & lens from falling to the ground should it become unlatched and swing open. These are BIG, heavy luminaires compared to what's installed nowadays.

Yeah I know, much heavier than my M-400's.

I am glad this OV-25 is in good shape, was surprised to find one. Well two actually.

I am going to trade the other OV-25 for a fixture I want and I still need a refractor for this one...

I wonder how much this weighs compared to a Powerlite B2255, since they're roughly the same size as each other.

I bet the B2255 weighs more since it is much bigger. How heavy is your B2255?

Did you open the door all the way first before taking it off, they don't come off if they are halfway open to prevent door flying off.....

This fixture probably weighs the same as my OV-14B from 1957

Yeah, the door still won't come off. A part of it wants to go out, but the other is stuck in there, so it's hard.

@Ian I weighed my B2255 it's around 40 lbs with a replacement 250w MV/MH ballast, and I think the original ballast was roughly the same. They also came with 400w and 1kW ballasts so I imagine those would be a lot heavier.

This OV-25 might be around the same...

The only person who has BOTH in his collection is Niall. xD He can compare.

My American Electric 125 Series weighs about as much as this light.

I somehow doubt that, the 125s that I have weigh nowhere near as much as my OV-25. As for the OV-25 vs B2255 I would say they weigh close to the same, though the B2255 does weigh a bit more, it also depends greatly on the ballast and since my 250 B2255 has a replacement ballast it weighs less than it would of with the original ballast, the OV-25 still has its original ballast.
