Energy saving: LED lamps with the same power consumption is only 10% of the incandescent lamps, which is more energy-saving than the sky lamps. Long service life: LED lamp beads can work for 50000 hours, which is longer than the sky lamp and incandescent lamp. Dimmable: the previous dimmer has always been aimed at incandescent lamps, and the light line of incandescent lamps turns red when dimming; It is difficult to see the dimmer of the sky light, which is the main reason why the dimming technology has not developed for many years; LED can be dimmed again, and both light and dark light are the same color (color temperature basically unchanged), which is obviously better than the dimming of incandescent lamps.
