The bulb says it is suitable for totally enclosed luminaries. Has anyone used this bulb in such a fixture for an extended period?

Where did you see they were suitable for totally enclosed luminaries? I don't see that anywhere. The heatsinks on them get too hot to touch. These are my first LED bulbs, and from what I've read some get hot and some don't. So I don't know if that is going to affect them; being on all the time, or being totally enclosed. I don't see how the plastic globe part of them doesn't melt unless it's some kind of high-temp plastic.

I purchased 10 3-packs for my home about 6-months ago. The majority of mine are located in enclosed fixtures. 6 have already failed. Finding LEDs that truly work in enclosed fixtures at the brightness you want, and the color you want can be quite challenging! I have other brands/models in my house as well, but none with a failure rate close to these.

I don't know what you mean by luminaries, but I ordered this very same item on October 9, 2013. I bought them for my hallway light fixtures which specified 40-watt bulbs. They arrived on October 11. Because I live in Alaska, I let them warm up for 3 days. I installed them October 17. By November 11, one had already stopped working. The others do get hot. I am much happier with the ones I got from Miyatsu U.S.A. They are much cooler. Good Luck

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.

The box indicates it shouldn't be used in totally enclosed fixtures or "insulated air tight recessed down lights." I'm not sure what insulated air tight means in this case but if your fixture is open and ventilated if think you were good. The light itself should be great illumination wise.

I guess it would work too. I am impressed how well it goes on every time I enter. It took a few attempts for the bulb to start working but now it works like clockwork. The light is good but it is not a big spotlight.

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.

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.

The manufacturer indicates that their bulbs only be used in non-enclosed fixtures (as they need air to cool the LED junction, or they will burn out quicker, how much is hard to say). This marking is typical of every LED bulb I have used though. The bulb will still operate, you just will not get the life that it is rated for. You may want to call Philips customer service and ask your question also and ensure there is no safety risk besides the shorter life.

The bulb is suitable for damp locations. Do not use it if directly exposed to rain.

Be careful. I have seen some specifications on these types of bulbs that state they should not be used in a fully enclosed fixture. For your safety, I would double check that this one could.

This fixture is only designed for fixed installations. It is a halogen bulb and consequently runs very hot. I have put it on an occupancy switch to insure it turns off when not in use. If you use a separate power cord, I would recommend insulation rated at at least 140 degrees C.

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.

i am currently using these in almost that exact fixture without any problems. you might find however (unless you set the motion timer to stay on a reasonable time when it is tripped) that the bulbs will not last as long as they would in a fixture that is turned on for a reasonable period of lighting time and then off. in my case the lamp is lit from approximately dusk to dawn continuously and they have lasted an extremely long period of time.

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.

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.

I haven't. But You can use any bulb that you prefer as long as it fits with the base, the fixture's dimension and the maximum wattage allowed. What I use for this one is actually a globe bulb. I love it because the lighting is very pleasing in the eyes. Bright yet cozy. Plus, it's really durable and high quality. Hope it helps!

This depends on the bulb, not on the fixture. This Sunlite fixture is a "fully enclosed fixture," so theoretically you should only use bulbs in it that do not say "not for use in fully enclosed fixtures." I don't know much about CFLs, but with LED lamps the problem is that the the bulb itself cannot handle the heat generated and trapped within the globe. There are plenty of LED lamps that are appropriate for use in enclosed fixtures like this, but they tend to be significantly more expensive than standard LEDs. That said, I am currently using some colored LED bulbs in these fixtures that are NOT rated for fully enclosed fixtures, and so far I have not had a problem. Only time will tell if their life will be diminished, but as I understand it, in the case of LEDs, the danger is to the bulb, not to you or your environment, so you could just try standard LEDs.

Yes. The bulb is safe to use in any standard socket/holder as a spotlight. It gives heat and some ventilation is necessary to prevent overheating.

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.
