The energy efficiency rating scale was revised in 2021 to make it clearer and more future-proof. The new classes range from A to G and replace the old A+, A++, and A+++ ratings.

LED lights rated F or G today were often rated A+++ in the past – their technology has not become less efficient. The scale simply became significantly stricter. At present, only highly specialized LED spotlights with cold, uninviting light achieve classes A to D.

Comfortable LED lights with warm light, dimming capability, and high color rendering almost always fall into classes E, F, or G. This is not due to poor efficiency, but to deliberately chosen light quality. The difference in electricity costs is often only €3–4 per year – even with daily use.
