    First, if you are replacing recessed lights, you should just use the right replacements. For example, here's a page from Lowe's: recessed lighting. The important point is to make sure there is enough air flow that the heat doesn't build up. Generally, these fixtures have openings that dump the excess heat into the space above the fixture. (I'm not plugging Lowe's; it's simply the first website that came up in the search. I suspect you'd get the same results with any large company.)

    Since LEDs generate far less overall heat than incandescent bulbs, they should operate well in most places where you would put an incandescent. I have several, and I've used them for months. Most of mine are in lamps, where there is no enclosure.

    I have one in a globe enclosure (about a six-inch globe) and the globe itself doesn't get noticeably warm. I suppose if I left it on for a long time, it might heat up, but it has been in use for months and hasn't failed.

    There are LED "light engines" made for all different applications. Buyers simply need to look for the kind of replacement depending on the use. They should also check the packaging for limitations. For example, many LEDs are not designed to be used outdoors, where they would be exposed to moisture and extremes of temperature.

    So, yes, you could create a heat problem if you put an LED into a totally enclosed space that was too confined for it to radiate off the extra heat. The best advice to avoid this is to read the package before you buy and get what you actually need.
