Can this be used in an enclosed (dome-style) ceiling fixture?

This depends on the dimensions of the fixture. I noticed that the bulbs are roughly the same size as a standard 60w incandescent bulb so if you used one of these previously you should be fine.

Yes as long the dome is big enough to hold the bulb. Do not use a dimmer switch on this type of bulb.

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

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.

Hi I think it would work the bulb gives off little heat. But check to make sure it would fit in the fixture your planning to use

Yes. The main thing to consider is how to attach the housing, and whether your ceiling can support the weight of the fixture, or if another piece of assembly is required to hold it right.

I'm not a electrician, but since this is a low voltage fixture, you dont need a lot of clearance between the fixture, just cut 4in diameter circle in the ceiling tile or sheet-rock and push the insulation away few inches with your hand and you should be fine. Hope this helps.

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.

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'm an engineer who designs buildings. Our lighting designers say that LEDs should not be used in enclosed fixtures, but that does not match my experience. I have 5 Besa Bobbi ( http://www.amazon.com/Besa-Lighting-911052C-Collection-2-Light/dp/B000TF9OTE ) ceiling fixtures (which I love) with two of these per fixture, and I have had no failures. I think it is a heat transfer issue. If the fixture were only rated for a 20 W incandescent there might be overheating, but I think that any fixture rated for 60 W lamps will not overheat with 9 W LEDs. I even have one marine light using these on a porch.

I do not believe this can be mounted as a ceiling fixture. It is impractical and it would hung sideways.

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'm not am expert, but I don't see why not. Especially if it will be enclosed. Led lights are not affected by temperature swings like CFL bulbs.

I don't see why not. If you can use a normal incandescent bulb in your fixture, you should be able to use this one as well.

I use them with enclosed fixtures so far without any issues. However the thing to remember is how they fit dimension wise. My ceiling lights are enclosed and are big enough to accomodate the extra length of the bulb. Also, I have noticed the heat factor is low compared to incandescent bulbs, so in my opinion these bulbs are just fine for enclosed fixtures. Hope this helps

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

I don't see why not, it's wired like any other ceiling light fixture. You will need a dimmer switch.
