Who told you that?

As long as they fit, it's fine to put them in enclosed fixtures.

They produce a lot less heat than similar sized

incandescent lamps.

Depending on the size of the bulb a certain amount of heat is produced.

Not being able to evaluate EVERY situation, the manufacturers put out a blanket statement such as "don't enclose".

I have hundreds in enclosed fixtures and no problems. Some of the lamps have it's own enclosed fixture. Good Luck.

I fairly have been employing the potential effectual bulbs interior the enclosed furniture, and that they artwork tremendous. one among them is in an enclosed fixture over the kitchen sink. The bulbs are lots cooler than the incandescent bulbs. subsequently, the kitchen would not get as warm.

Somebody is blowing smoke up your area. I use them for every application That I can. What they will not work with are dimmer switches (unless the fixture has a dimmable ballast). They do contain mercury, though, so you need to make sure that you dispose of them properly.

who says? i have 6 of them in enclosed fixtures that are hard to get to. they produce very little heat, so that cant be the reason. i was told by an electrician to use them and there is no reason not to.

As long as there is room for the globe or cover to properly fit over the CFL, it's not a problem.
