G9 LED Bulbs - do they burn / melt?

[phinix]

I just had 2 G9 LED Bulbs burnt and melted - it happened pretty quickly, one after another, 2 of out 5 bulbs in ceiling light made loud pop noise, couple leds inside burnt to black and melted plastic cover. Scary, as I thought these are safer than any standard bulbs. These had around 5 years, in case its just a matter of time?
Is this normal, possible behaviour? I cannot find anything about those going up with smoke...

so.. the situation is, alot of these ledchips are actually defective, but they package them anyway because no one checks.

this happens in alot of the cheaper led products.   if you look at those led floodlights under the microscope not all the leds even light up, but  because it's  a flood light, you can't tell.

it could also be bad drivers, or errant surges on your house circuit, low cost drivers are more sensitive to that.

I never had issues with lights in a house. I swapped all lighting to G9 leds about 5 years ago and these two are first to be burnt. Few have stopped working in the past, but never burnt, or melted.

tp, do you ever sleep?

I get about two years out of an LED bulb.  I got two years out of a CFL bulb.  I got about two years out of an incandescent bulb.  I get about three years out of a flourescent, probably because they're not in places where they get a lot of use.

The Phoebus Cartel shut down in 1939.  Supposedly. https://en.wikipedia.org/wiki/Phoebus_cartel

The CFLs generally went with smoke, and a couple of times with enough heat to melt the styrofoam ceiling tiles above them.  The LEDs usually just smell bad and quit.  In both cases, the power supply is the apparent failure.  I've harvested a modest collection of mounted LEDs from dead bulbs, which will probably sit in my project box forever.

This is very interesting, never heard of that Phoebus cartel.
