How can you tell if a light bulb is energy saving?

With traditional bulbs, we used watts to determine the brightness of a bulb, but watts measure power consumption rather than brightness. Energy-efficient bulbs use fewer watts, so it is best to look at lumen output.



Select the right lumen value.

How does an energy efficient light bulb help conserve electricity?

LEDs use diodes to produce light. Other light bulbs create light using heat, which takes a lot more energy than the use of diodes. The lifespan of a LED lasts over 60,000 hours compared to the 1,000 hours of a traditional incandescent bulb, this saves a lot of energy used to produce and dispose of the bulbs.

Are LED lights energy saving?





LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting.

What does B stand for in light bulbs?
