IC recessed lights getting hot?


Hi there,
I have been browsing the forum for a while and finally joined. Hopefully I can help others in the future because this forum has been a huge help to me!

I am remodeling my attic and I installed 3 can lights in the roof. The room will be finished off with drywall, knee walls, etc. My question is, I bought the IC can lights so they can be in contact with insulation. The attic space gets really hot in the summer (even with the proper ventilation). Anyways, the insulation and drywall are not up yet, but in the middle of the day, I put my hand on the metal light casing (its a metal box around the 4" can) and the metal box gets pretty hot! I can keep my hand on there, it doesnt burn, but still really hot.

This does not happen at night, when attic temps are cool. My question is, will this be a problem? I was planning on putting insulation right up to the can lights. There is ventilation from the soffit vents, all the way up to the ridge vent. I am assuming all the heat generated by these lights will go right out the ridge vent about 8" above it.

I have read online that they can get up to 90 deg. C before the shutoff feature kicks in, and that they run hot because they are radiating the heat through the aluminum enclosure. They are HALO brand if that makes a difference. Anyways, I am attaching some pictures to help clarify....Thanks!

Oh, and FWIW, I am using 50w equivalent CFL bulbs. So really, each one is using like 16 or 20 watts? I just dont want to start a fire!

You say they're IC cans...you should be fine. I have 13 of them in direct contact with the insulation in my house. No problems. Some have 65W & 75W incand, couple have 46W CFL (roughly...200W equivalent).

Yes as long as the are rated for contact with insulation it will be fine.

thanks for the replies! I figured as much. I try to do my homework ahead of time (even if it means completing projects slower).

On a side note, these were super easy to install and they have these quick connect connectors that you just push the wire into and it holds it in place...

Took all of 10 minutes to install!

Unrelated, but make sure you remember to install baffles underneath the insulation on the slanted part of the ceiling (so that air can flow from the soffit vents to the ridge vent). Otherwise all that attic venting will be for nothing!
