What makes a light bulb exploded

Excess heat will cause the sealant to melt around the base of the bulb which allows the gas to leak out and causes an explosion. LED bulbs emit light through a semiconductor, instead, LEDs would explode in extremely rare cases due to electrical and thermal stress. On average, an LED bulb only required 2 to 4 volts of electricity to function. This can be pretty problematic since the average household wall outlet is about volts.

In order to counteract this, LEDs require a capacitor that drops the mains voltage down. This is a huge task which means that capacitors get stressed. If there is an electrical surge then the capacitor may accidentally let the full current through to the LED, and in this scenario, regardless of how long this exposure is present, the LED bulb will then explode.

If a bulb explodes in your home, you need to first of all make sure the power is turned off. You do not need any power going into a shattered bulb. You should also clean up.

Some bulbs are more prone to shattering than others, incandescent bulbs are big culprits of shattering into a million pieces when they explode, whereas LEDs are more likely to break into a few easier to clean pieces. You need to turn off the power and wait for it to cool down, while you wait to clean up, you do not want to be stepping on bits of a broken bulb especially if you have kids or pets in your home.
