There is definitely a negligible amount of heat created by every LED bulb in my home. I have LEDs of all types inside and outside my home. If you put your hand to them you can certainly feel a small amount of heat but nothing compared to incandescent.

Sure wish SGL wouldve taken off 40% like they did with the coupon for the 6" ones, but still an awesome price. Bought & repped!

"NO lead,UV, mercury or thermal radiation"

Really? NO thermal radiation? These are so efficient they don't even radiate heat? Sorry, but I'm not a believer.

It's not negligible. It's a lot of thermal radiation for someone to be claiming there's none!! The degree to which you notice it is a whole different issue.

That's a bold lie by the seller. I am no thermal dynamics or physicist expert but don't all light give off heat signature with the exception of glow light using chemical like the ones you see in remote control buttons or glow sticks?

That's what I was thinking. I had LED bulbs all over my house and the brightest are too hot to remove while they are on.

Now, on the item page under technical details it states this: "Cooler running LED light bulb, with lower heat output so it won't cook your fixtures, which makes them safer as well". Sure, I believe its cooler but I have bulbs and LED flashlights that generate an immense amount of heat.

It is negligible. Go ahead....plug in 2 100W equivalent bulbs for 15 minutes. I'll unplug the LED. You unplug the incandescent. First to unplug bare handed wins.

A quick look at LED and thermal radiation (heat). Mostly to educate myself, but also if anyone else was inquisitive.

I realize this is an older article and the efficiency has greatly improved, but this gives a general understanding.

How about you unplug the "negligible" LED bulb in my kitchen ceiling and tell me its negligible? It's damn hot for something that gives out negligible (or NO) thermal radiation. Hahaha

5000k is too white for my tastes.. Wish this was for the warmer 3000k's...
