We bought some "off brand" PAR lamps. Very short lived and with some catastrophic failure modes. Just pushed us into replacing with proper theatre grade LED.I have been buying theatre lamps from China, they are cheap and so far reliable, with millions of halogen luminaires in the world and the cost of LEDs prohibitive for infrequent users like schools, there is a vacuum in the market which China seems happy to fill. Plus the fact that a halogen is so much better quality light than cheap LEDs and much more reliable and cheap to fix.
When GE stopped production, I bought every last PAR56 NSP I could find in any quantity. I must have around three dozen of them. Grainger was the last place to sell them, and they are mine, ALL MINE.
Our LED swap came down to economics and infrequent lamping. Something about a 14' lamp changer pole OR needing to walk on the 100-year-old plaster ceiling makes it not so fun. (I also set off the fire alarm changing a lamp...)Unfortunately true (currently, anyway), which means they'll be struck trying to use "domestic" LED eventually, which they'll be unhappy with, but them's the breaks.
We had been using E27 PAR38 screw in lamps in our houselights. They are currently still available while stocks last, but the price is much higher than we used to pay (around 4x). Economics can force your hand. How much are you prepared to pay to continue using the the same lamps?

And here's where that gets complicated, @DELO72:
That second block appears to be largely the same as the first block (a list of things not General Service Lamps, and hence not restricted from manufacture)... but because of that, it becomes unclear what the "this definition" at the head of the second block applies to.
It really feels like that second block should be exceptions-to-the-exceptions--things which *are* (again) subject to manufacture restriction. Was this somehow just an infelicity of copy-pasta? Am I misreading it?
Or did they miswrite it?
Well, I'm assuming you quoted all the relevant parts; I was hoping for professional interpretation.Here's the entire law- enjoy the read. https://www.regulations.gov/document/EERE-2013-BT-STD-0051-0097
