How much heat is generated by this bulb? I would like to seal the back side of the light can, any fire possibility?

It's not recommended that it be put somewhere that won't allow heat to escape. It does produce a small amount of heat. I don't think it would start a fire, but it's life would probably be shortened. I personally wouldn't do it.

I'd definitely consult the manufacturers of both the bulb and the can. The can manufacturer may recommend against sealing for any fixture that can still take an incandescent. This sounds like it might be used for new/gut work, so you might also want to consult your local inspectional authority ahead of time. If your goal is a super-tight or even just a tight house, please also be aware of HRV/ERV code requirements, whether or not there is any non-sealed combustion in the house.

After being on for several hours, the back of the bulb is too hot to hold and ambient air temp (by rapid response cooking thermometer) is >30 degrees hotter than room temperature. I would be concerned about sealing the canister.

Not much, they barely get warm. You can easily handle them bare handed even when on full for quite awhile.

This is the BR30 OUTDOOR version. This is NOT a replacement for R30 indoor recessed can lights. Very little heat produced. Anything designed for incandescent bulbs can use this without any worry. Feit makes the best quality LED bulbs I have been able to find in 10 years of trying them out. I have been an electrician and contractor for 35 years. All DIMMABLE LEDs are made better than Non-Dimmable. Look for that on the labeling.

I have not measured the temperature after the light being continuously on for a long time, but there is a plastic shroud over the electrical terminals. If the light gets too hot it will melt the shroud. I hope that will not happen.

The issue is not the amount of heat in the box but the power getting to it. I don't see a rating on the 4-way light socket. However, the bulbs that came with them are 30 watts (120 for 4) and the power cord is pretty skinny. I would be reluctant to go a whole lot higher (say 50%)without confirmation either from a rating somewhere or the mfg.'s suggestion.

I would just buy a cool tube light and call it good. Its a bit too narrow to let an HID light free hang in there with no cool tube it will get hot quick anyway you'll at least a 6" inline fan for proper venting even with a cooltube.

We have the Feits in new cans, and there is no issue. I checked and the surface glass is only warm to the touch, but the white back (ceramic?) is hot, about the temperature of a 75W incandescent bulb. Elsewhere in the house I am using CFLs in old 100W cans and there has been no issue.

It is never too hot to touch the metal desklamp shade I have above it. It gets very warm but not hot. I would say less than or about the same as a 40 watt bulb.

I have not measured the heat output between the two bulbs and I have not had any heat problems. My guess on the heat would be the same or less. They are way brighter than the 24W bulb and I am happy with the light output.

Any heat created from this bulb is very small. I have a second heat lamp to supply heat for my bearded dragon.

I don't think you should use heat emitters with this lamp fixture, cause of the heat output would be to great and definitely started a fire.

Sorry, but I'm traveling for the summer and don't have access to the bulb to measure it, but it is a big bulb. I am using it in a ceiling fixture and am not aware of the temperature.

I wouldn't suggest doing this as a 60w bulb can get quite hot. I'm sure there's another product that's designed to do what you're looking for, and this is not it.

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.

The bulb is effectively 3 parts. The top part (the glass section) is where the emitters are (1100 lumens is very achievable with one emitter, but this design probably uses multiple). If this gets too hot to touch, that's bad. The second section (with the fancy fluting, and which should be metal) is the heatsink. It is perfectly normal for this section to become too hot to touch during normal operation. The third, very bottom section (smooth plastic) should not be getting too warm to touch during normal use, as this is where all the fancy electronics sit.

It is not going to get any brighter and a larger watt bulb will generate too much heat. The lens is opaque and limits the brightness of the light. Replace the dark plastic lens with a cut piece from Home Depot that allows more light to pass through.

Very strange. The same thing happened to me. You can get a replacement bulb pretty cheap at the big box stores. Was easy to replace. However be careful. When I first set it up, the bulbs got so hot that it burned a hole in the side of the box.

I found on the internet that the +C may mean the bulb is coated to reduce heat to the fixture.. if that's the case then consider that these bulbs are only 3W, and produce very little heat.. make your own decision from there....

With LEDs you can't really translate lumens. I used the light with pretty good results. You want an open area, as to trap the heat released by the lights side exhaust. The light itself doesn't cause much heat, but the fan exhaust do!
