How do these bulbs function when put into "cans" in the ceiling? There is no ceramic covering around them like the Sylvania Bulbs. Overheat?

I've never put them in a large can, my fixtures are designed for these to fit snugly in them, I've never experienced any overheating issues with mine.

I am sure they get hot. I bought LED bulbs on amazon and they work well and stay cool and are dimmable.

I'll say yes, with this caveat: Like any halogen bulb these things get hot and they really should not be used in an enclosed fixture with no airflow or very bad airflow. I put these in a chandelier in my parent's house that really did not have good airflow, just a small opening at the top; and in that situation the lifetime of the bulbs is shortened.

Depending on the heat dissipated by the current bulb you're using. If these type bulbs don't cool off or are encased, they can melt. I tried using one of these for accent lights in a headlight harness and melted away.

I do operate (4) of these lights in my ceiling fan and have no issues. The room is a lot brighter than the Compact Flourescent bulbs they replaced. I have ordered over (30) bulbs, some do give a little buzz most don't. Im still pleased with the purchases.Randy

I haven't had that happen to me. My regular bulbs would run so hot they were burning my covers. These bulbs can stay on for a while and the cover isn't even warm.

I don't notice that they give off a lot of heat. We have them in our glass globe pendant lights over our kitchen island and another set in our sconces in our family room (up high.) Not sure I would notice the heat factor based on the location but I think they are actually more subdued than regular bulbs. They cast a really nice yellow/goldish hue.

I did not use mine with a dimmer. I used them in can lights in my kitchen. However the answer M. Thiel gave makes sense. The bulbs don't get hot at all and that's why I like them.

I am useing the flat lightbulb shaped LED bulbs in mine and have had no issues. They are cooler and brighter and it is noticable. The other bulbs were very hot, expensive and delicate.

A ceiling fan is what I purchased these bulbs for, but they will only work if your fan was designed to use this type of bulb. If your fan takes a standard bulb these will not work, the base will be way to small. Hope this answers your question.

I have about 40 of these in overhead cans. The former incandescent bulbs were very hot. Too hot to touch after being on for less than 30 seconds. These led bulbs are cool to the touch at any time. No heat problems even after hours of operation

You can just reach in and change the bulb. We have it in living room and bedroom and have not noticed any heat. They look great.

No, I have not used those Sylvania bulbs. I ordered the GE energy smart 60 watt replacement bulbs pack...13 watts each bulb. They are working fine.

I purchased Cree LED light bulbs at Home Depot which seemed to solve the problem. Apparently these bulbs are more efficient (lumens per watt), which implies to me less heat is being generated. These bulbs are also cast a more diffused light that other LED bulbs. Note that LED can lights are designed for the can enclosure, which is not true for LED light bulbs. Someone mentioned dimmers not working. I have found out that the dimmer needs to specify that it will work with LED lights to work properly.

CF bulbs will not provide heat like incandescent bulbs. If you are counting on heat from you overhead lighting then stay away from the CF.

Wow, I use them in my chandelier which has a "small" base, but it's been so long ago! Don't have any to look at. I get my chandelier bulbs at Lowe's now.

I second what the others said. The problem with an enclosed fixture is the heat build up shortens the life of the bulb. This bulb produces only minimal heat.
