Would heat be OK in overhead can enclosures? (3/4 sides enclosed)
370744
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

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.

should be ok in any overhead recessed fixture as the 8w will not produce much heat, so no heat senors on any recessed lights would ever trip.

Yes, it needs to put in a junction box and keep away from insulation 3-4 inches.

It says right on the neck of the fixture NOT FOR USE IN ENCLOSED LUMINARY. Many commentators stress how little heat comes from these bulbs. That is true on the lighted side. The backside or the side in the enclosed can is another matter. If you feel the backside cooling fins you'll soon realize that plenty of heat is generated, so much so that inside an enclosed can they'd be too hot to touch. That is undoubtedly the reason for the disclosure stated in the first sentence. What is at issue is the build up of heat. Will it trip the cutout? Will it affect the electronics that make the LED function? I have these same lights in enclosed cans in my house. For years I had halogen in the same cans. The cans are rated for insulation coverage. At the very least I'd expect a drop in life expectancy. It'd be nice to have a little vent in the can to vent the heat.

It gets hot to the touch, but unless your partial roof is RIGHT on top of the heater, I'd think it would be ok.

MANUFACTURER RESPONSE: Thanks for asking! Sorry, but no. We would be concerned about heat buildup issues in this scenario, and would not recommend it. Most of the multi-bay NAS and USB multi-drive enclosures have a cooling solution for this reason. Sorry we can't offer a more helpful response, hope the details help!Best wishes-Jeff EverettTechnical Support EngineerPlugable Technologieshttp://plugable.com/supportLinkedIn: www.linkedin.com/in/jeffleverett

These get very hot and blocking the vents on the top would not be a good idea. You would need space above it for air flow.

It is a matter of heat; to be as water tight as possible, this case pretty much encloses the head unit so there is not much free air circulation. If you stuff a more powerful head unit in there and crank it up, the heat may build to where it toasts the unit... big bucks literally "up in smoke"! I do not know at what point the plastic of the enclosure will melt, but that is always a possibility also. I suppose if you are mechanically inclined you might mount a 12 volt box fan (like from a computer) to try and move more air through the enclosure. Anyway, heat is the reason, and the more Watts you stuff in there, the more heat you will produce.

Yes, it can be easily installed (retrofitted) into an existing recessed can. It will fit nicely into a 4" can with open trim. There is no heat problem in this application because the open trim provides adequate air circulation even when using an IC can. Even if it was a closed trim such as a shower fixture, the chip of the LED bulb wouldn't produce enough heat to cause a problem.

I don't believe the plastic insulation could sustain that kind of heat. The insulation is very similar to bubble wrap used in shipping packages. Even if you were fortunate enough to not have smoke and a fire from using it with so much heat, I suspect it would quickly melt the plastic and lose most of it's insulation value. Just my opinion. I only use it on conventional heating ducts.

Heat comes out the back. (which would be the bottom if you are trying to put the image on the celing) As long as you can keep the vent free of obstructions you should be good, but if you can't do that then you may have a problem.

recommended only if the space behind the cabinet vents to some open space. otherwise, the cooler will overheat.

I used it on Level 3 and the sides were warm but not too hot to touch. That being said, I wouldn't let kids around it or put it close to anything.

I built a pine box with inside dimensions of 3"x4"x60" and got it up to 210 degrees. It would work better with an insulated box.

I think it would depend on the height of the ceiling/roof. It puts off a good amount of heat but because of the diameter it dissipates about 5 to 6 feet up. So if your roof was hi enough I think youd be fine.

Henry - it might, but it will depend on the rate of heat loss - so how cold the surrounding air is, whether there is any insulation, whether the top is open for heat to rise out of your desired warm area. Mine are in an insulated wooden box that is ~3x3x3" out doors where the temperature gets down to freezing but no lower, and indoors in a terrarium that is ~1.5x1.5x4 . The temperature inside is 50-75 and the only way I can keep the terrarium cool enough (below 83) is to avoid covering the top. Best of luck.

This is a link to the installation instructions . http://king-electric.com/pdfs/PAW-installation.pdf . There is no mention of insulation proximity to the outside surface of the can . Since the can is attached to a wooden stud it is logical there would be no restriction regarding the outside surface . Personally I would give the outside of the can some space as I would a recessed lighting fixture can .
