One of the reviews "looks like it generates too much internal heat". But I thought LEDs do not generate heat?

I don't remember having an internal heat problem with them but I've swapped them all out for this LED bulb: Lighting EVER 10 Watt A19 LED Bulb, 60 Watt Incandescent Bulbs Replacement, 830lm, Samsung chip LED, Daylight White. This LED bulb offers the best trade off in price, wattage and amount of light in my opinion. But you have to be someone who likes Daylight White.

Too much heat? If it conducts electricity and its not a super conductor it generates heat. Way less heat than a light bulb. What's your idea of "too much heat"?

You shouldn't have any problems with it as long as you feed it 16 volts or over and use a proper heat sink on the led.

No generally LEDs do not produce heat anything like an incandescent, but I am using them in motion sensing outdoor fixtures that are enclosed in glass, they stay on for 5-10 minutes at a time generally but they will be fine in most applications and not get very hot, I have all sorts of LEDs installed besides these in use outdoors I have PAR 35 flood lights and several indoors that have not been a problem at all.

You only have to worry about heat if you are using an incandescent bulb. Fluorescent produces some heat, but nowhere nearly enough to damage what you are enlarging. LEDs produce such little heat that it isn't a concern. You just have to find one that fits right.

I've never had this problem. An LED should NEVER get any more than slightly warm unless something is wrong.

I would assume that the issue is total load on the device (the internal wires are very small) and perhaps a heat concentration issue for incandescent bulbs. I would also think that LEDs would be OK.

Bulb has an internal fan that (I'm guessing) is necessary to dissipate the heat generated by the very bright LED(s). If you put the bulb in a completely enclosed fixture there wouldn't be any place for the heat to go. I think it's a terrific bulb for all other uses and the 3000K color temperature is just the right amount of white light without being as "yellow" as a 2700K bulb. If you're sitting next to the bulb in a quiet room you can hear the whir of the fan, but it usually just blends into the room's usual background noise.

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

I haven't tryed heat emitters in it yet . So far I have only had a Exo Terra Repti Glo 10.0 UVB compact 26w in it and it's been working great ! . If you put a emitter in please let me know how it works :) .

I can only can give my opinion but, in any past experience I have had regarding LED displays like this is not good.Generally, you would have to replaceThe whole display module.... But I might be wrong. :0/

I am almost certain it will not last long. Cooling is still a big problem with LEDs, most of them quickly overheat in enclosed space and die.

The threaded area is made of plastic so temperature is their main concern. LED's should be fine.

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.

You may have a incandescent version. I bought 10 thinking they were all LEDS and took them apart and all NON LEDS running super hot with no load.

Haha, make sure the curiosity doesn't get the better of you and make you open it up for a tour. I am also wondering how its managing heat. My guess is the traditional copper piping with aluminum "fin" style heatsink attached behind the LED chips with the fans blowing across.

I don't notice any heat output from mine; however I put LED bulbs in the fixtures, and these don't produce much heat anyway. LEDs are much more expensive, but last about three times as long as halogen bulbs. It you use halogen bulbs, I think a lot would depend on your ceiling height.

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.
