Why do light fixtures have insulation




















Now, I don't know much about codes and regulations, and I'm new to working on my own home, but this screams "fire hazard" to me, so I want more input before I install a bulb and continue to use this.

Is this okay to have insulation next to something that gets hot? Think about it, though. Those incandescent bulbs are inside a glass globe. You need to press it back into place somehow. Since then I've had a set of Cree bulbs in that look like new when I checked on them a few minutes ago. Show 1 more comment. Active Oldest Votes.

I'm actually a bit surprised to see the exposed fiberglass and the foil. Press the trim ring into the caulking. Reinstall the bulb in the recessed light fixture. Do LED recessed lights get hot? LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. If you have fully or semi-enclosed fixtures you need to light up, look for LEDs that are approved for recessed or enclosed spaces.

Can you lay insulation over electrical wires in attic? If there is not anyinsulation in your attic, fit the insulation between the joists. Don't compress the insulation to fit behind pipes or wires. Instead cut to the middle of the batt's thickness so you have a flap under the wire and one over the wire. Can junction boxes be covered with insulation?

Don't let any insulation touch bare wires, and keep insulation fibers out of electrical outlet boxes. Unless you are an expert DIYer, hire a pro for safe insulation installation.
