Hi, wondering how does this lamp dissipate heat; should one cut the recess hole large enough so that the heat can flow through the holes in its side?

I agree with the other 2 answers. This fixture also has very little rim space so you don't have allot of wiggle room. LED technology is so nice because you don't have to worry about heat buildup like you do with other light sources.

There's very little heat to dissipate due to the large size of the fixture.

Mainly to let heat out. With a perforated lid it still gets too hot without the bottom removed. You can get an LED bulb and leave the bottom attached if the lid is perforated properly, it puts out less light though.

You might have to cut it or wrap around sides. Depending on room it might put out too much light. You could always put a dimmer switch on it.

I've installed a dozen of these in 4" recessed Halo-brand fixtures with trim (H99 is the Halo Model number). There have been no overheating problems (the fixtures have a heat sensor and turn off if they overheat). I think the LED bulbs don't get nearly as hot as Halogen bulbs.

specifically the base does get hot to the touch but it seems very little if any heat is given off. There's nearly no discernible heat from the bulb/light and almost no heat given off in general. Should be completely safe for fully enclosed fixture.

On mine,the shade also gets hot as the bulb warms it. This may be due to the fact that there is metal surrounding the plastic. I do see that on mine that the entire base that plugs into the wall is NOT WAR OR HOT. I also see that there is no burning of the plastic sheathing under the metal shade. I leave mine on, day and night. Please call the manufacturer if you have a concern and let them know what you are or are not noticing. Best Wishes!

I have not noticed significant heat generated, the lamp is warm to the touch but I don't think it's terrible.

Although it fit my regular lamp, it also only lasted 5 weeks. There's a statement that it's not for enclosed light fixtures, and I now wonder if that is because of excess heat. The one I used is a spotlight style, with a cylinder about 6" across and long enough to enclose the bulb. (I didn't want the extra UV affecting my furniture or my skin.) Perhaps that was too small for the bulb to be able to dissipate the heat?

One last point. When you handle the lamp do not touch the bulb itself. The oil from your fingers can cause an uneven heat distribution on the glass which has been known to break the glass at temperature. Suggest you use surgical gloves.

Last winter I placed two old lamps toward the outside edges and hung a work light (attaching the hook to the roof rod with a zip tie to keep it away from the plastic). This allowed for plenty of heat during the night when temps dropped to the teens. I threaded the wires outside the upper window and took precautions to protect all electrical items from moisture, both inside and out. For watering, I removed all the lights. Also, we used tent stakes to secure the base, as we had some strong winds last winter. Never had problems and am expecting many years of service.

It does not get too hot as its only 10 watts. You should be fine putting it in an enclosed fixture.

I can't say with 100% certainty but the design suggests that it needs to be flat on the floor. Given that heat rises and there is no fan in this unit, a floor position is going to produce the optimal results. There are no heat vents on the sides and the bottom is aluminum.

If you have a mesh top. Cover your top with aluminum foil. It will help retain heat. If not get a bigger bulb and bigger fixture. I stopped buying these because they only last a month or two until they blow out. The element melts to the copper conductor inside the fixture. No problems with the outlet it was plugged into either, the house in only a year old.

Dear Michiganian,I tested the bulb and touched it while it was on. Didn't know or care before. You can touch the plastic part where the light shines through, no problem as it is only warm. The metal part in the middle of the bulb does get a little hotter though, I would say hotter than warm, but not really hot. I can still touch it. Hope that answers your question.

i dont really think it good to place it in a closed fixture. It may gets hotter & hotter and eventually shortens LED lifetime quite a lot.

Its not really a relevant concept I suspect. IC is a heat related issue, and IC recessed lights have a larger casing around the overall bulb housing that protrudes into the insulation space to dissipate the heat. These produce almost zero heat, as well as don't protrude into the insulation space as they're flat, not much thicker than the sheetrock.

I don't think it would heat as large an area as a regular bulb, but it is smaller and you can chain them 6 of them together to save outlet space. It also has a ceramic bulb which is much harder to break during transport.
