can this bulb be used in an enclosed fixture ?

I can't imagine why they would not work in an enclosed fixture... They are slightly larger in diameter than a traditional bulb, but they fit into my glass shades OK.

No. The packaging that is with the bulb states "Do not use in enclosed fixtures", under "CAUTIONS & WARNINGS". LED lights fail if they become too hot, that's why it has cooling fins at the base of the bulb. An enclosed fixture would trap the heat.

I believe it could be used in an enclosed fixture. I have my 18 watt Cree bulb in a table lamp, and there is no heat generated as would be typical with a 100 watt incandescent light bulb.

I bought hs bulb a couple of monts ago and am using it in an enclosed ceiling fixture. I'm totally satisfied with it thus far.

What do you mean by an enclosed fixture? Though i don't see why not. I've been replacing the bulbs in my house and others because of the lower power use/heat generation. Low energy bulbs are saving me tons of money. Since there is far less heat generation I don't see why this would be an issue.

While they will work in an enclosed fixture, be aware that their life may be shortened. The electronics in an LED bulb are sensitive to heat. Even a modest rise in ambient heat (such as trapped in an enclosed fixture) will cause the electronics to age more quickly than when there is air circulation to keep them at room temperature.

This fixture is at my customers sink so I can't look at it. However since there is an LED bulb made for every base that I know of, I would be certain that there is some form of LED bulb you can use in this. It is open at the top so it is not considered an enclosed fixture. If you will find out the base required once you receive this you can Google or eBay that base and the word LED and you will find your bulb. It is truly an incredibly beautiful fixture.

yes it can and it works well except in tight fixtures!!!! The bulbs wont last as long as you think....

It can be used in an enclosed case as it generates very little heat. The bulb I bought on Amazon from one of their sellers lasted only 6 weeks and I could not get a response from the seller. I have had 3 of the Phillips LED bulbs that I have in enclosed outdoor fixtures that have performed flawlessly for 3 years and counting so I would stick with them rather than the cheap LEDS. It seems you get what you pay for.

We use ours indoors. Most bulbs for indoor use are not rated to withstand outdoor temps. Why don't you contact the distributer

The Cree 18-Watt (100 Watt equivalent) bulbs will NOT work in ANY fully-enclosed fixture. They will overheat & burn out very quickly. They generate more heat than they can withstand when enclosed. I have spoken with Cree, & they said that their 75-Watt equivalent bulb (and below) CAN be used in fully-enclosed fixtures, but the 100-Watt cannot.

Hello. If there is some ventilation there should be no problem. But using a complete sealed fixture (like IP65), this could overheat the bulb. Your technolamp Team.

I'll say yes, with this caveat: Like any halogen bulb these things get hot and they really should not be used in an enclosed fixture with no airflow or very bad airflow. I put these in a chandelier in my parent's house that really did not have good airflow, just a small opening at the top; and in that situation the lifetime of the bulbs is shortened.

As long as that your lighting fixture is water proof and the bulb is away from rain or water, then it should be fine. However, completely shielded lighting fixture might shorten the lifespan of a led bulb.

I second what the others said. The problem with an enclosed fixture is the heat build up shortens the life of the bulb. This bulb produces only minimal heat.

I don't have any experience with these lights in outdoors fixtures, but they look pretty well sealed and I wouldn't expect a problem in an enclosed fixture.

It's a totally enclosed fixture. Not an issue. There is a 12volt set of leads on the bottom. These can be buried directly because it's low voltage.

No. Printed on the bulb itself is the text: "Caution not for use in totally enclosed luminaries suitable for damp locations"(two separate lines split between luminaries & suitable. It is not clear to me if this means it can be used in damp locations or not, but definitely not in enclosed lamps.)

I know from my own use that the "bulb" doesn't get too hot to touch, but the ceramic base of it does get hot. Personally, I wouldn't put one in a fully enclosed lighting fixture for that reason. It IS a great light bulb, however. Wonderful lighting in my desk lamp.

I would think so, I've used them in enclosed and non-enclosed fixtures with no problems.

That question is a tricky one. It depends how the manufacturer and what the manufacturer uses to dissipate heat generated at the junction between the circuit board and the LED. In sealed industrial LED applications, the heat sinks are enormous and can tolerate the junction inefficiency. I seriously doubt that residential LED bulbs are designed for that purpose, so I would not recommend using these in a sealed fixture.

Can this be used outdoors in a mostly enclosed (bottom is slightly open) post fixture?
