New “drum light”

[tom baker]

Installe led 12” round surface light, what I used to call a drum light. 1200 lumens, $20, consolidated electric, adjustable color temp. Light weight and easy to install.
But requires 90 deg c comductors, part of my wiring is 60 degrees c. That must be boiler labeling from UL as this luminaire operates very cool, not like the drum lights with60 watt incandescent that would bake the insulation

It's probably cooler than anything it's replacing. I have never once worried about this.

 

[tom baker]

Agree.

When you say "part of my wiring in 60C" do you mean at some of your luminaire locations you have 60C wire?

Or do you mean you have 90C wiring at the luminaire location, but 60C wire elsewhere in the branch circuit? I thought that was fine fine, the 90C requirement is only at the luminaire.

Isn't all NM cable 60⁰ ?

No, it has 90 deg insulation, but we have to use the 60 deg column.

Makes a lot of sense, somehow. Maybe why few worry about it.

This is something I don't get. Every fixture I have seen says 75C minimum conductors. So what are you supposed to do in an older house with TW insulation or worse?

Furthermore, don't LEDs give off less heat and run cooler and that is mostly what is being installed now so why the restriction?

Is it just the terminations they are worried about or the whole circuit.

Right. We know it has 90° insulation but it's not identified as such. At least I've never seen it
