Energy efficiency indicates how efficiently a lamp or lighting fixture uses electricity in relation to the amount of light it produces. Highly efficient lamps use less power to produce the same amount of light, helping to reduce energy costs and protect the environment.

• Energy-efficient lamps: provide a lot of light with low energy consumption, such as LED lamps.

• Less efficient lamps: use relatively more energy to produce the same amount of light, such as older incandescent or halogen lamps.

Nowadays, many packaging labels display an energy rating on a scale from A+++ to E, where A+++ indicates the most efficient lamps and E the least efficient.

By choosing energy-efficient lamps, you can lower energy bills, extend lamp lifespan, and contribute to a more sustainable world.
