led lights

[goofin]

The thing is, you don't know if it's the LED component itself that failed or some supporting component without actually tearing it apart and testing the junction of the LED. Even those little CREE flashlights have some supporting circuitry. I can guarandamntee you that any LED bulb that's plugged into 120vac has some circuitry in there to convert AC to DC to the voltage that's needed for the bulb. If it's dimmer capable, then there's even a few more components in there.

my rope lghts start out as 120 volt 0.15 amp ac and is stepped down and converted to 12vdc 1.6 amp.
I bout 2 strings last christmas at Ollies for 10 bucks each.

ollies have the replacement power cord but no rope lights.

I can't wait to see how long they last.

If you've ever been behind a tractor trailer with LED lights, you've seen one with LEDs burned out. Yeah, the ones that supposedly "never need replacing".

The LED third brake light on my truck cap is down to one, or two remaining functional bulbs out of about twelve. My incandescent tail/brake lights have never been replaced in 11 years.

"Quit Emitting Diode"???

"Quit Emitting Diode"???

Exactly. We find it to be a more elegant term than the more colloquial Dark Emitting Diode, or DED.

Yup. That's when they're working. When they fail the process reverses and they no longer suck, they emit. When this happens most folks say "The bulb/lamp must be dead". Little do these rustics know how close their spelling is to the physics of the thing.

I'll bet it is the wiring or a bad manufacturer. The overheating people are talking about is how LEDs are amp hungry. They will suck as much amps as they can get and overheat until the basically melt. This shouldn't happen over a long period (days) of time but more like hours or seconds even. I'd check the application and if there is a broken wire in the string of leds before anything else. That is the more likely culprit. Check the other thread for further thoughts.

+ rep for this one.

Don't dismiss this idea folks. I've seen this done before It's very effective, since the light distribution is ideal. And it requires lot less light, since shadows are almost non-existent. With LED Christmas lights, you're looking at serious MTBF numbers. And it works outdoors too (think extended picnic hours).

LED Christmas lights are an abomination.
The colors are all wrong and they are harsh to look at.

Whoever chose "blue" as the "power on" indicator for electronics should be kicked in the groin repeatedly. That is such a painful thing to look at.


I'll think of more later.

I cannot tell you how much I agree with this. The TV in our bedroom has a blue LED to indicate when the power is OFF. I have a piece of black tape over it and you can still see it glowing. My apnea machine has blue LED's under the buttons, I have tape over them and they still light up the room. Fortunately, since I have sleep apnea, I can easily cocoon myself under the blankets and be happily in pitch black.
