Dimmable, color temperature changeable LED ceiling light integrated 4 lighting modes into 1 lighting fixture. Use wall switch or remote control to select nature white, cool white, warm white, night light mode & patent anti-burglar function. Different from TRIAC dimming, the power consumption of this ceiling light decreases when dimming to darker, only 2W consumed when dims to 5%, it is really energy saving. The advantage is that it can automatically light up as an emergency light and provide 2 hours lighting time when power supply fails.
