High luminous efficacy: LEDs themselves have a luminous efficacy exceeding 130 lm/W, so the overall luminous efficacy of LED crystal ceiling lights can reach 100 lm/W. Moreover, this efficiency is increasing annually; it is estimated that by 2020, the luminous efficacy of LEDs will reach 240 lm/W.
High luminous efficacy means energy saving. According to actual measurements, an 8W LED can replace a 32W crystal ceiling light, saving more than four times the power consumption. Long lifespan: LEDs have a lifespan of 100,000 hours. When made into lighting fixtures, the generally accepted lifespan is at least 30,000 hours, with high-quality fixtures reaching 50,000 hours. Therefore, the lifespan of LED ceiling lights is generally between 50,000 and 70,000 hours.
Mercury-free, no ultraviolet radiation, no light pollution: Can provide various color temperatures as needed, typically 2550-3700ºK and 4700-7000ºK. No glass components, impact and vibration resistant, easy to transport. No need for aluminum heat sinks, low cost, and lightweight.
