What kind of light do I have?

JD, what tells you that this instrument is not watertight?

Well, "water resistant" would have been a better phrase to use

Vent holes
Open switch at top
Cable strain relief
No front or rear gaskets

To me, the big clue to what may have been it's intended use is that gap at the back on the handle, including what looks like a rubber protection foot inside it.

The light doesn't even look like it was designed to swivel. Why would you have a spotlight inside a pilot house with a switch on the outside of the actual fixture? Maybe the switch was actually installed later, as well as the stage-pin connector?

That space between the back end of the handle and the back of the housing is intriguing, and it certainly looks like one could use it to hang this light on the edge of a piece of 1x lumber or a steel plate or beam. But the possibility of portability doesn't jibe well with a yoke that looks like it's made for a semi-permanent installation.

Or they would have a stepdown transformer built into the fixture, for a single lamp.

Good MorningTom

I've mostly used PAR 64 ACL's so they were always on a 4bar
I forgot about the smaller ones.
