Will these bulbs fit in an enclosed ceiling light?

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 have had one of the philips LED bulbs inside a fully enclosed fixture for about six months now (I believe it is 429258). It will surely shorten the life, but it remains to be seen if it just shortens it from 7 years to 3.5 years, or if it is about to give up the ghost any day now.

It's not a question of total watts of heat. It's more an issue of how much heat in how small an area, the area being the bulb base with the electronics inside. There are flammable items in there if overheated. However, high heat will, as others have pointed out, cause the electronics to passively fail (i.e., fail before fire). It would be best not to use bulbs in a full enclosed fixture if the manufacture warns against such use. Btw, LEDs are more like about 35% energy efficient. You need a Mercury Quartz lamp (one of those awful looking parking lot types) to get up around 80% efficiency. A recessed fixture would be fine, but enclosed, not so good.

These bulbs maybe used in table and floor lamps, open pendant fixtures and ceiling fixtures including surface mounts but not usually in a recessed fixture. If a standard size incandescent A-shape lamps fit this should as well. Hope this was of some help.

yes, probably, they are around the same size as a normal full sized lightbulb, possibly a hair longer

LEDs are 80-90% efficient (80-90% of the input energy is converted to light, the rest is heat). 20% of 10w is only 2w, which would not get an enclosed area very warm, so I question the worries over heating, but the manufacturer knows more than me. If you have 3+ light sin ana enclosure, I suppose the 3-6w or more of heat could warm up the air a bit. You coudl always give it a try and do a test. Run the lights for an hour and then quickly take apart the fixture/globe, turn the lights off, and finally feel how warm they are. Compare that test/temperature with another bulb running for an hour but not in an enclosed fixture.

These will no doubt physically fit and work well. What remains to be seen is if the excess heat inside an unventilated fixture will reduce their lifetime.

I don't think there is an LED bulb on the market that is safe for use in fully enclosed fixtures. They don't generate much heat at all, but they do generate enough to significantly shorten their lifespan.

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.

Yes they will fit. Anything that takes a nightlight bulb. Just dont know what your nightlights look like. If there open yes if the bulb has to fit inside the design then may be too long

Two of six that we placed in a single bulb outdoor enclosed fixture burned out in less than a week. The packaging does not say you can't use them in enclosed fixtures unless you are using them with other types of bulbs in the same fixture. YMMV

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.

Probably as they are LED. However, the dimmer will have to be inserted between the PE cell and the lamps and I am not sure there is enough room inside.

Not that I am aware of, I purchased two bulbs for my Hinkley landscape lighting and the bulbs are completely enclosed in a watertight enclosure. Sorry I couldn't be more help.

No. I don't think they will as they are pretty tiny shades. You would have to use a large base chandelier bulb in your lamps.

I'd suppose so. It fits a standard bulb fixture. Mine is a vintage style pendant light with a wire cage shade... very beautiful effect but I'd suggest putting it on a dimmer. At dim light it's beautiful to look at and can be in an exposed fixture otherwise they are very bright.

I found them at my local hardware store (Orchard). The 'candelabra' type of bulb will fit. However I tried a larger wattage (slightly - their manual says 25w max - I found that 40 would work without it getting too hot). The light is still not bright enough to be very useful.

Not usually. These are the two pin type bulbs so you would need that type of recepticle to fit the bulb.

Would these fit inside recessed fixtures?, I currently use Sylvania MR16 halogen bulbs

They will fit into a standard wedge socket, so I do not see why not. Remember though, if the bulb is used in a reflector type socket, unlike a regular bulb, these radiate much less light "backwards" toward the reflector. In a standard lamp, I agree with other, best used in a reflected or diffused lamp, as in a direct view, you will see the "spots" of this lamp.

Yes. I have several cree bulbs in enclosed fixtures and have had no problems with them.

The bulbs should work fine if not totally enclosed in a fixture. If the are completely enclosed, the will get hot and die. The color of daylight is bright white which should work well for art.

Yes, I believe they can. These have the same screw size as regular light bulbs. However, they are curly light bulbs and as such, will be slightly longer than regular light bulbs. I was going to use these in the overhead fan in my dining room but my family freaked out at the bright light, LOL. So yes, they would fit, but they will be super bright up there.

Yes, regular incandescent light bulbs will fit, but anything over 40 watts will be very hot. The recommended fluorescent bulb will run much cooler and last way longer.
