Thanks to a built-in LED, this light is extremely energy-efficient in operation. LEDs (light-emitting diodes) have the advantage over traditional incandescent bulbs of not generating heat, instead converting most of the energy into light and thus consuming only a fraction of the electricity. Because LEDs are flicker-free and have a high color rendering index, their light is always pleasant for your eyes. Objects illuminated by LED lighting appear in their true, natural colors. Additionally, LEDs are extremely robust and long-lasting; therefore, the light requires very little maintenance despite its high lifespan.
