Ugh, thats just sloppy.
Now, there are manufactured varieties of this from Kliegl, Altman and Century. (I know because a few were still hanging around in the shop at college). There are also ellipsoidal varieties as well. These all date from the most early days of halogen-incandescent lamps.
Not sure who ever even allowed them into manufacture, as a linear lamp in a reflector designed for a point source sucks. I guess they just wanted to print "halogen" on their advertisements and give a **** all to performance.
One must first know and understand the rules of theatre before one can break them.
Love the wire-nuts!

But its UL listed!





Well, that's just disgusting.
I like Derek's repurposing better.

That's my guess as well. Or possibly the reflector or socket was damaged, so they retrofitted it with what they had on hand. Also possible that they wanted more light from the fixture, so they figured that three lamps would be brighter than one.
This is an item I found for sale on eBay. The price isn't bad for an Altman 75, if it was in original condition. I was thinking about buying it until I saw the insides! It isn't worth it if I have to buy a new reflector and socket.

I think it would then take the designation of "assembled from UL Listed components". Whether or not these components play well together... ehhh. Actually, aside from probably getting INSANELY HOT, I doubt there's much about it in the way of being unsafe (aside from the wire nuts). Janky, yes.
It looks like someone probably found an old 75Q shell and wanted to convert it in to a location fixture or something. At least, I hope they didn't destroy a good fresnel for this.
Yeah, you can find whole 75Q's on eBay for way cheaper than it would take to repair this one. Seems like I was shopping around on Production Advantage for fresnel socket/reflector assemblies and it was something like $65 for the 65Q and $110 for the 75Q.
