are these bulbs designed for fully enclosed light fixtures?

It will work in a fully enclosed fixture but does not have to be fully enclosed

It depends on the light fixture. My bathroom one has a little pyramid of metal in it that prevents light bulbs that are too long from being used so this one doesn't fit in that. I would suggest buying one and checking it throughout the house where you plan to use it before getting more. It works in all of our other light fixtures so hopefully it will work in all of yours.

I believe these bulbs need to be in an open fixture...They can be placed in a dome fixture if it's not full enclosed.

yes, they are fairly small and fit in (if you mean something like this http://www.amazon.com/Yosemite-Home-Decor-JK101-11SN-2-Light/dp/B003ARSZWU/ref=sr_1_1?ie=UTF8&qid=1396141276&sr=8-1&keywords=ceiling+fixture), however enclosed fixture might diminish the output.

I have used them in all the fixtures in my house for months now, dropped my energy bill by 20%. I have several dome type ceiling fixture that are enclosed, i have also used them outside, exposed to the weather and as of yet, they all work great. I have had one bulb out of the 20+ that I purchased go bad. If by totally enclosed luminary you mean a sealed outside light fixture, I have not.

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.

I haven't seen anything regarding this but I would not hesitate to use them in an enclosed fixture. If memory serves they only draw about 1/2 watt so any heat buildup should be minimal.

Yes. I have my Cree bulb in 2 outdoor fully enclosed lighting fixtures. These Cree bulbs are ideal for that application.

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.

Sure. Mine are in recessed ceiling fixtures and work fine. Keep in mind this type of light produces like one-tenth the heat of an old-fashioned incandescent bulb. That's why it is so energy-efficient- minimal energy lost as heat.

Not in my estimation. But that being said, there is no such thing as "too bright" in a garage like work place. I'm not 20 anymore. YMMV. I did have a 50% instantaneous failure rate (the fan quit working) on the two I ordered. In free standing, downward facing open fixtures I'd think that'd be the BEST application for these lamps. Anything enclosed, not so much. They appear to be a first attempt and as such, I think they'll get the kinks out.

I ordered this lightbulb over 6 months ago, and it's in an enclosed fixture. So, yes it works in an enclosed fixture. At least it has for me.

yes.These bulbs are well protected when they arrive be careful when you open package they pop out easy.I been using my every night still working.

If you read the VERY fine print on the box, it says "This lamp is not suitable for totally enclosed fixtures". Unfortunately, you cannot find this information anywhere on the Phillips site (or on Amazon). You first have to buy the bulb, take delivery, and read the fine print (on the bottom of the box, no less) before deciding whether to return for a refund or, like we did, repurpose the bulb(s) for use in lamps or other open fixtures. There are other manufacturers out there that DO have LED bulbs that are suitable for enclosed fixtures and damp environments like bathrooms.

I don't think so, because it would need to be protected from direct moisture I'm sure and one of the provisions for use states it cannot be used in enclosed fixtures.

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.

The ones I got were 6" deep with no cover. So you could put in longer bulbs but they would stick out.

I'm using them as vanity light, but there's no reason they couldn't be mounted in any orientation or even in an enclosure. On the contrary, I would actually say these bulbs are preferable for enclosures since they are only 6 watts and generate much less heat than a standard bulb...
