Does the base get warm in use? Other candelabra LEDs do. Need for fully enclosed fixture.

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.

The base is metal and serves as a heat sink, which does get hot to the touch. The plastic cover stays relatively cool. Otherwise it does not radiate heat the way a conventional incandescent or halogen does. They won't likely heat up your room.

haven't had any problems with this. I have them in enclosed globes both ceiling and wall and they do just fine. I think the key is that it not be a sealed fixture. In other words, if air/dust can get into the globe it's probably going to be fine. If the light has a seal / gasket of some sort around it to make it airtight/dust proof, then I wouldn't recommend it. Best LED lights I've purchased so far!

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 light it self (led) will not create heat at all. You will not feel any energy heat come from the light at all.

If I needed a light to always be on I would get one with an LED bulb. I have never noticed this light getting hot. I use a 20 watt bulb in mine, so its on the low side of energy usage, compared to incandescent bulbs.

Yes, LED do not get hot. When you touch the bulb, it cool feeling. Incandescent do get very hot! Highly recommend LED!

You want a shade that allows air flow to the bulb. This light doesn't get as hot as an incandescent bulb, but it does generate heat and that heat can damage the electronics if it's in a completely closed fixture.

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 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.

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.

I called manufacturer with same question. LED lights (and CFL's) have built in ballast which do generate some heat, but not enough to be dangerously hot. However, enclosed LED life is reduced due to the heat that cannot be dissipated. For maximum life results, it is not recommended for enclosed appications. In my application even if life is reduced by 1/2, it is still cost effective vs incandescent bulbs due to change out cost. I have had these bulbs enclosed for over a year in bathroom application with great success so far. The instant full bright feature is hands down better than CFL's. Even at 0 Degrees F on patio in winter, it is full bright instantly. I'm very happy. I called manufacturer with same question.

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.

Hello Patricia. I have an overhead kitchen light fixture that used to eat regular incandescent bulbs in a matter of a few months, then compact fluorescent bulbs also in a matter on a few months. I have two of these LED bulbs and they run much cooler. Be aware that they are not as bright but the glass enclosure does not get hot. I barely even gets warm. My answer is Yes.

The bulb is effectively 3 parts. The top part (the glass section) is where the emitters are (1100 lumens is very achievable with one emitter, but this design probably uses multiple). If this gets too hot to touch, that's bad. The second section (with the fancy fluting, and which should be metal) is the heatsink. It is perfectly normal for this section to become too hot to touch during normal operation. The third, very bottom section (smooth plastic) should not be getting too warm to touch during normal use, as this is where all the fancy electronics sit.

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 believe it could be used in an enclosed fixture. I have my 18 watt Cree bulb in a table lamp, and there is no heat generated as would be typical with a 100 watt incandescent light bulb.
