Incandescent light bulbs are not energy-efficient because they produce light by heating a filament until it glows, which wastes a lot of energy.

LEDs have the longest lifespan of all types of lighting, lasting up to 50,000 hours.

LEDs are the most energy-efficient type of lighting, using up to 85% less energy than incandescent bulbs.

LEDs are the most expensive type of energy-efficient lighting to purchase, but they also have the longest lifespan and are the most energy-efficient.

LEDs are the most environmentally friendly type of lighting because they do not contain mercury, which is a hazardous material.

Energy-efficient lighting has a longer lifespan than traditional lighting, so it is not a benefit.

Energy-efficient lighting can have a higher initial cost than traditional lighting.

The most important factor to consider when choosing energy-efficient lighting is the energy efficiency of the bulb.

Leaving lights on all the time is not a way to save energy with lighting.

All of the above are good ways to reduce energy consumption from lighting.

Lumens measure the amount of light emitted by a light source, while watts measure the amount of energy consumed by a light source.
