Benefit from longevity and energy efficiency: LEDs (light-emitting diodes) have the advantage over conventional light bulbs that they do not generate heat, but convert most of the energy into light and therefore only consume a fraction of the electricity. In addition, LED light sources are extremely robust and do not need to be replaced for a long time. Because LEDs are flicker-free and have a high colour rendering index, their light is always pleasant for your eyes. Objects that you highlight with LED lighting appear in their true, natural colours.
