Is this bulb suitable for a completely enclosed fixture? My ceiling fan uses 4 of this type.

A single bulb works fine in an outdoor enclosed fixture and the vibration of a fan should not be a problem. Whether the heat buildup would be a consideration would depend on the configuration of your fan. If all 4 bulbs are in the same enclosure and it is recessed or against the ceiling, it could be a problem. If they are in separate enclosures and well away from the ceiling, it should not be a problem.

I used this for an enclosed outside light fixture which required a bulb roughly the size of an incandescent light bulb. I had no issues with this bulb. However, I have a couple of ceiling fans that require bulbs with similar bases, but the prongs are closer together and they are more like little flood lights, so i would recommend verifying that this truly is the appropriate size bulb you need.

We put a regular incandescent bulb in it. To be honest, I don't remember if it said NOT to use CFL. It is an open fixture, so I would think it is OK unless you don't want the screwy design of CFL to show...and not sure if it would. If you like the design, read the enclosures more carefully that we did.We have CFL wherever possible, so we are not anti-CFL, anti-halogen or anti-LED.

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.

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 the package it says: "Not suitable for totally enclosed fixtures". The keyword here is "totally". I won't get too worried about using it in my enclosed ceiling lights. As long as the fixture is not air-tight, it should be fine.

The led bulbs work well in enclosed locations. Just make sure the size of the bulb will fit.They are good for stove hoods and ceiling fans because they generate much less heat.

The packaging indicates you should not use these bulbs in a completely enclosed fixture. It doesn't say if there are safety concerns, or if the primary concern is decreased bulb life due to heat generation (which is minimal anyway).

Most led bulbs are not designed for enclosed fixtures. Try Home Depot they have a display showing what look like a led ceiling conversion. I have 12 volt ceiling fixtures and I replaced 50 watt halogen bulbs with Philips EnduraLed 10 Watt MR16 and they work great.

I am using mine in a ceiling fan (the fixtures are not fully enclosed, they are the bell-shaped type that are open on one end) and they are fine. I also am using one in an open in-ceiling can fixture, for downlighting. They are great and very bright. The only annoyance I have noticed is that sometimes one of the bulbs emits a high pitched buzz. It doesn't happen all the time and I've not diagnosed the cause. Overall, I'm thrilled with these bulbs, though. They are VERY bright for 9 watts.I have had no problems with ghosting at all.

Phillips says the fixture should not be enclosed. However all parts of this bulb measure temperatures far lower than a comparable 60 watt incandescent. If the alternative is using a 60 watt incandesent bulb in an enclosed fixture or this bulb, the temperatures will be much less with this bulb.

These bulbs have the small E12 threaded base. I think most ceiling fan light fixtures require the larger E26 base. However, if your fan uses the E12 base these may fit and the description says they withstand vibration, so they should hold up in a ceiling fan. But, I don't have any experience using them in a ceiling fan.

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.

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 just called CREE and the customer service rep told me that the 40, 60, and 70W replacement bulbs are ok for an enclosed fixture. The 100W bulb is not.

when i read the manufactures directions on the package it did not say it could not be used in fully enclosed fixtures it just stats not to mix different bulb types such as cfl in the same fixture

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.

My fixture uses four bulbs and there has not been any problem. Wish I could be more informative.
