What's the effect of turning on the light all night and forgetting to turn it off the next day?

It doesn't matter. At best, these lamps are of poor quality. Resulting in damage to the power supply or light source. At present, the light can be turned on for a long time, and the biggest damage to the light is the moment of switching. It's always fine.

Bulb life:

1, LED bulb life

The life of LED (single-finger light emitting diode) can theoretically reach 100000 hours.

But after being assembled into lamps, it is also related to the life of other electronic components. That is to say, if the service life of the LED lamp is less than 100000 hours, there may be failures, not necessarily the LED itself, but the power chip, electrolytic capacitor and other components may have problems first.

Then there are many LED manufacturers with mixed quality.

1, service life of energy-saving lamps

The most common ones are 2000 hours, 3000 hours, 5000 hours, 6000-8000 hours, 10000- 12000 hours.

2. Ordinary incandescent bulbs

The rated service life is about 5000 hours. However, ordinary incandescent lamps may not be turned off when they reach their service life. The life of ordinary incandescent bulbs is longer than the fixed 5000 hours ~
