About the video “Better light with less energy”

This page will guide you through the issues presented in the video.


The lamps available on the market can have very different energy efficiency, which is expressed by the European lamp energy label on an A to G scale. If you choose an A-grade lamp, you will make important savings on your electricity bill. This is true even if you take the higher purchase price into account. More information on the available lamp types.

A-class lamps bring electricity cost savings


It is the light output (in lumens), not the watts, that describes lamp performance

The same amount of light can be produced by light bulbs using very different amounts of electricity. It is better to describe and compare bulbs by the quantity of light they produce (expressed in lumens) than by the power they need (watts). You will find this advice explained in more detail alongside a lot more in the Frequently Asked Questions.


The lower the colour temperature, the warmer the light colour

Energy saving bulbs provide not only cost savings but also a wider choice in terms of light colour than conventional incandescent bulbs. When you select them, you should keep in mind the circumstances where they are going to be used (such as a dimming luminaire), so that they work best. We provide you with detailed advice on how to choose energy saving bulbs.

The packaging of lamps provides information on dimmability


Shops selling the bulbs will usually have recycling containers

When they reach their end of life, energy saving bulbs such as compact fluorescent lamps and LED lamps need special attention.
