I see heat being mentioned as an issue. How does the heat of these bulbs compare to a traditional bulb? I assumed these would be cooler, am I wrong?

They run cool, i haven't had any issues with heat. I've purchased 6 so far.

I think its cooler than an incandescent bulb. But the fins part gets too hot to touch.

Gets a bit warm but not as hot as traditional bulb.... It works well.... Nice light

Hi J....I measured the temp at the base of the bulb where the heat synches are and it was consistent at about 135 degrees. The bulb itself was warm to the touch. A typical Edison bulb would burn your hand if the bulb was touched. If you are using the bulb in a lamp it will not effect the bulb in the least. However the back of the package states that you should not use the bulb in a totally enclosed fixture. Hope this helps.

Most of the heat from a candescent bulb is dissipated via radiant energy. Most of the heat from LED bulbs is dissipated via conduction, either through sockets/fixtures not designed for such a purpose, or to the air, which is why the bulbs are typically surround by finned heatsinks. The problem is fineed heatsinks do not work effectively with stagnant air surround them.

I would have to say the light coverage would be every bit as good as any other type of bulb in a recessed light fixture. The lights are only warm to the touch, so there would not be any heating issue.

Its not really a relevant concept I suspect. IC is a heat related issue, and IC recessed lights have a larger casing around the overall bulb housing that protrudes into the insulation space to dissipate the heat. These produce almost zero heat, as well as don't protrude into the insulation space as they're flat, not much thicker than the sheetrock.

probably not.. depends upon the design of the bulb and the fixture they are being used in. I am using them in the bathroom in an overhead fixture, where they are seldom on for more than 30 &gt; 60 minutes, and would not know how warm they get as they are out of my normal reach. However, the heat sink on most LED bulbs I have dealt with does become quite warm (to the point where you can not unscrew them without a glove or something) after being on for a while. So, i would say any "120 vac house lighting" bulb would not be cold after 2 hrs, as they are pushing a lot of power thru the LED's (to get the maximum brightness) and need to dump the excess heat into the heat sink (which is why they have the big heat sinks and say do not use them in totally enclosed fixtures where the heat can't get out).

Depending on the heat dissipated by the current bulb you're using. If these type bulbs don't cool off or are encased, they can melt. I tried using one of these for accent lights in a headlight harness and melted away.

The bulb is normal color, but it gets very hot....hotter that I want or felt was safe for plants.

This bulb is a spot lamp bulb not like other bulbs. the fouces a beam or channle of heat to one area were normal bulbs scatter heat. so they will help heat a the basking area, theses do over heat very eay. do not use mimi dome lamps were theres isnt wide enough. my beared dragon would only bask around this hot zone never dirrectly under it wich did lead to him stay at temps around 85 or 82 degrees. even rising the lamp dome up higher didnt help. be care full of theses bulbs.

You can just reach in and change the bulb. We have it in living room and bedroom and have not noticed any heat. They look great.

Should be OK as long as it is not exposed to rain and there is no accumulation of water in the fixture. These bulbs do not create a lot of heat but it is best for them to have decent ventilation.

While still "warm white," they are slightly cooler than the traditional incandescent bulbs. I would estimate about 3000K vs. the usual 2700K. However they are not in the "daylight" category (6000K). You might notice a slight difference if you mixed bulb types.

I have about 40 of these in overhead cans. The former incandescent bulbs were very hot. Too hot to touch after being on for less than 30 seconds. These led bulbs are cool to the touch at any time. No heat problems even after hours of operation

I did not see a "color temperature" rating, but the bulbs are fairly close to the "white light" from older incandescent bulbs. I think you wouldhave to check with the manufacturer for more detail than that. Sorry.

I don't notice that they give off a lot of heat. We have them in our glass globe pendant lights over our kitchen island and another set in our sconces in our family room (up high.) Not sure I would notice the heat factor based on the location but I think they are actually more subdued than regular bulbs. They cast a really nice yellow/goldish hue.

I found on the internet that the +C may mean the bulb is coated to reduce heat to the fixture.. if that's the case then consider that these bulbs are only 3W, and produce very little heat.. make your own decision from there....

Like all halogen bulbs, the bulb itself gets very hot. You won't feel it heating the room, but it would burn your fingers nicely if you touched it. They work well with a dimmer switch, which is always easy to put in place of a regular switch...

We are using an energy efc. bulb that does not get hot. An old stile bulb might be a problem if too high wattage. We are very well pleased with our lamp.

I would say yes; they run cooler than standard blubs. Heat build-up is the only problem with this type of reflector housing. These are rated for a 150 watt incandescent; which get very hot. I use 100 watt florescent bulbs in the two I have with no problem.
