Can an LED light bulb explode if you leave it on too long?

I bought a standard LED light bulb and it gets hot after being on for 12 hours. If I leave it on too long, will it explode?

    Bought one guaranteed for 7 years and left it on for about 4 years, no problem.

    It's not the "LED", it's the electronics that can be the issue.

    Can the electronics go bad and catch fire or explode, yes.

    LEDs run on a tiny amount of DC (battery) voltage. We would be better off, in the future, to have 12-48vdc in our light circuits so that it could power LED bulbs directly and not have all this special circuitry to change 120vac to battery voltage in every single device!!!.

    Just so you know; a lot of early LEDs were made for 12V, especially if you are getting them overseas.

    They WILL explode if you plug them into a 110/120 volt appliance.

    Be sure the voltage is correct.

    Otherwise, no, they shouldn't explode.

    Highly unlikely.

    Well, for the wattage they do get hot, but not as hot as incandescent light that uses heat to produce light.

    No, they won't explode, I have two in the house that go 24/7/365, and two years now.

    Hoping they will go another couple or few years.

    Update if you need more, and please choose 

    a best answer from among those you get.

    LEDs in the 20 - 60 Watt range designed for illumination 

    generate quite a bit of heat (this is not true of the 

    20 - 60 milliwatt variety).

    Assuming an Edison base fixture, you must examine 

    the fixture for labeling which shows Wattage limits.

    Most ceiling fixtures are marked with a limit of 40,

    60, or more total Watts. Exceeding the limit will

    over heat the bulbs and damage the fixture.

    Hmm. you might not have an LED bulb.  I have one in a reading lamp and I leave it on for HOURS at a time, yet I can touch it after all the time.

    I've had an LED light bulb explode on me once. Turned out it was counterfeit. The risk is much smaller if you have a real one from a reputable brand.

    Are you sure its an LED? As they generate minuscule heat as its not a filament. I have LEDS on 24/7 as do many businesses, they do not explode.

    No. It's not under pressure, and it doesn't contain vapor, so there's no way for it to explode. It could theoretically melt, but so could any electrical device.
