Second, LED ceiling light power
LED ceiling light usually needs the drive power supply， the quality of which determines the life of the entire LED ceiling light , there is usually no problem that the lamp beads can be used for more than 20000 HS, but if the power supply is broken , the whole LED light will be not lit up . If we consumers do not understand the components of knowledge , we can know from the size of the power , weight, and electrolytic capacitors, consult the manufacturer for the initial judgment.
Third, understand the brand and packaging lamp beads :
The quality of light beads determines the lighting effects of LED Ceiling light, and the key factors affecting the packaging process is the lifespan and heat dissipation . The current chip lamp beads are from U.S. and Taiwan ,Japan and China. the lighting effects of US and Japanese lamp beads is much better than the lamp beads made in China in terms of skill , but the price is a little expensive . However, many of particularly cheap LED ceiling light are laid using chip production line to produce defective products ,which has inconsistent color temperature , brightness difference , short life , consumers need to pay attention.
