1.Check radiator used by the LED ceiling light :

How the lamp bead of LED ceiling light dispose the heat determines the life of the entire lamp and lumen. Lamp beads of LED ceiling light work for long hours under high temperature , the light fades quickly, resulting in that the life is very short , the dark LED ceiling would not achieve the effect of accent lighting .

The radiator schemed of LED ceiling light are the integral heat sink and a lamp beads with single column mode and additional fan cooling methods.

What way the costumers  accept is currently a heat lamp bead with single column mode . This way rapidly dissipate heat generated by single light -emitting beads through the column to ensure timely dissipate the heat . The overall heat radiator are conducting all of the heat generated by the lamp beads to aluminum plate , and then disseminate through the radiator , cooling at a slower pace .

Size of the radiator , the quality of the aluminum material affects the rate of cooling of LED ceiling light , but also affect the price of the whole lamp .

2.Make sure choose the correct power supply ( commonly known as the transformer ):

The quality of Transformers also determines the life of the whole LED ceiling light , there is no problem for the lamp beads used for more than 50,000 hours, but if the transformer is broken , the whole lamp will not light up. The electronic components used in the transformers and he design determine the efficiency of the transformer, power factor , stability, temperature rise , life.

Costumers do not understand the knowledge of components , it can be judged from the initial size of the transformer , weight, and consult the manufacturer what are the electrolytic and capacitors . The quality of the transformer undoubtedly determines the price differences of LED ceiling light.

3.Understanding lamp beads brand and packaging :

The lamp beads determines the lighting quality of LED ceiling light , the packaging technology affects the quality of lamp beads , there are U.S. chip, Taiwan chip , homemade chips and so on. Different brands, the price difference of LED ceiling light is large, the lighting effects are also great differences .

Users can learn by way of consultation with the manufacturer lamp beads programs , depending on the degree of integrity of manufacturers . Most of the particularly cheap LED ceiling light uses defective LED, inconsistent color temperature , the brightness of inferior LED ceiling light is different, the life is short，our users need to pay attention .Browsing http://www.lead-lighting.com/products/bid14-1.htm for more information about the LED ceiling light.
