Something like texie posted was what I had in mind, but not sure if they will hold up if in fixture with high temps. They probably are most popular one used in pole bases though.

Yes, those or similar. Being a novice at this one, what does 'breakaway' mean in context with these?

I believe the breakaway type is for light poles with breakaway pole bases.
A breakaway base is designed to breakaway from the pole and concrete base if a vehicle colides with it.
The breakaway fuse holder would safely disconnect from the load side without leaving a live wire exposed.

Bussman has a lot of options. Our pole bases are called "slip bases" if hit by a car the poles will slip out of the hold down bolts, the breakway fuse holders are intended to disconnect when that happens

More specifically, if the pole is hit, the fuse holder is designed such that the parts come apart and the line side is left electrically dead. It has an extra insulating sleeve inside that stays with the fuse and makes it come out with the load side. So when the pole is hit, the end of the fuse isn't sticking out there like a live "spark plug" waiting for someone to touch it.

Not in the fixture. More likely in the jbox directly above it. Not sure if that is even legal. in the thinking stage yet.

These could be mounted in a 1/2" KO when inserted from the outside the box and two holes drilled/ tapped and be used with spade terminals up to 20A. Rated to 600V

I have ordered fixtures in the past with these type units factory installed.

I had some issues with some 400w MH low bays in a dairy once. I was able to find some inline fuseholders similar to what MTW posted in either a Littelfuse or Bussman catalog.

I put them right in the wiring j-box at the top of the fixture, that was 2-3 years ago and I haven't had a call for them since.
