I have purchased LEDs in the past which have gotten very hot as the step down transformer produced a lot of heat. 120 V in and low V out requires some sort of in line transformer. .

me thinks you are not very experienced with electrical engineering

That might explain having to replace the tiny light on the underside of our NEW microwave TWICE in one year. If you haven't had to do that, it's a real trick getting it in without ruining the prongs!

I as well had issues with LED bulbs flickering and not lasting. But fortunately I found out that the bulbs I had were warrantied for 5 years. Westinghouse replaced my bulbs for free. I needed to show proof of purchase which I did because I ordered them originally from Amazon so producing the receipt was not a problem. Additional if the bulbs are on a dimmer a special dimmer for LEDS is required.

Hope this helps,

Thanks for all the replies. I have my answer, I'm not the only one with this experience. I didn't start this thread to get educated in electronics. I'm just a 78 yr old guy that has owned five new homes. By the way, number 6 bulb just went out. Lets close this thread, no need for further replies.

Coach,
I have done various engineering for 50+ years and believe in real life experience.

LED bulbs that I have purchased do not get very hot. The Led bulb uses very low electric power probably less than 10% compared to an equivalent light output incandescent bulb. My guess is that the integral transformer in the bulb creates a loss of less than 10% of the LED bulb power consumed.

The desk lamp I purchased can use a 40w incandescent bulb. When turned on you can not touch it without getting burned. I replaced the incandescent bulb with a 40w equivalent light LED bulb. I can touch the bulb when lit and it is very close to body temperature. The metal shade feels close to room temp.

Incandescent bulbs makes light by transforming power into light by heating the filament hence the large heat out....call 40 w...you can not touch a powered on 40w incandescent bulb.

The equivalent light LED bulb consumes less than 5w. Call 4w
The heat generated in the transformer creates probably 10% of the LED power consumed or 0.4 w

In round numbers, the incandescent bulb produces about 100 times more heat in the bulb.
(40/.4 )=100

I agree with the previous poster that LED bulbs should not burn out from excessive heat.

Well we don’t live in TV anymore but I had 2 bathroom LED fixtures changed, the first they did because our house was less than a yr. old. They said if it wasn’t under warranty it would of cost us $180. The 2nd LED I did myself in about 10 mins. & cost me $27. total. No way am I going to pay anybody $180. & probably more now. Your right when we lived in Ohio we had things done for FREE when we lived there for 8 to 10 yrs. Seriously LED lights only have a neutral wire (white wire) & a hot wire (red or black) then snap light in & turn it on. Hope this helps!

Incandescent bulbs are designed to produce light with heat, LEDs are not. My LED lamp bulbs are fairly hot, especially at the base. If the LED bulb is enclosed inside a fixture, excessive heat can build up, and cause some of the LED bulb components to fail. So, an LED bulb in an open air fixture is likely to last longer than those in an enclosed fixture.

After my sixth bulb went out I checked the temp of the others on that circuit. Three lamps above my island. After 30 minutes of being on the bulb was 104 deg. I could easily hold my hand on it indefinitely. The problem is not heat.

On my living room lamp LED bulbs, I can touch the glass part of the bulb, but the base is way too hot to touch. I don't know what caused your bulbs to fail, but, if you Google LED failures, there are many studies that say overheating due to inadequate ventilation is a major cause for failure.

I’m inclined to agree with whoever said bad batch of bulbs.

They did not to that for me.

During the villages early warranty inspection, that's what the light bulb guy said to me. There was a bad batch and they had to go around checking. Told me to test my lights, leave them on for a few hours. If they start flickering then they are part of the bad batch. So far I've had none do that.

Pretty sure they would replace them if yours failed. But gotta check with that one guy. Can't remember his company off hand, drove a big truck with his logo on the side. Not only deals with bulbs, he also checks the fuse boxes.

was told by the gentleman at Ace Hardware that the led bulbs don’t work in the overhead can lights that work off a dimmer switch. They blame it on the type the Villages uses
