Thanks to a built-in LED, this light is extremely energy-efficient in operation. LEDs (light-emitting diodes) have the advantage over conventional light sources that they do not generate heat, but convert most of the energy into light and thus consume only a fraction of the electricity. Because LEDs are flicker-free and have a high colour rendering index, their light is always pleasant to your eyes. Objects that you highlight with LED lighting appear in their true, natural colours. LEDs are also extremely robust and durable; the luminaire therefore requires hardly any maintenance despite its long service life.
