Benefit from longevity and energy efficiency: 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. Additionally, LED bulbs are extremely durable and do not need to be replaced often. Since 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.
