LED downlight point 1: the choose and buy radiator.

Cooling speed determines the LED downlight, the light failure degree and the length of life, the radiator is too 

small can make the heat accumulation within the light source, and the lamp bead work long time under high 

temperature condition, the light failure quickly, the service life is very short, so when choosing the LED tube 

light, suggest you had better choose made of aluminum shell, because of the aluminum heat dissipation 

coefficient is higher, heat dissipation is more fast, to ensure the normal order of the LED tube light illumination.

LED downlight points of choose and buy 2: drive power supply.

Drive power supply is also called the transformer, the life of the transformer quality also determines the whole 

lamp, lamp bead used 50000 hours no problem, but the transformer, if broken,can't afford the whole lamp also to shine.Transformer used in the design of electronic components,determines the efficiency of transformer, 

power factor,stability,temperature rise,the service life,so when buying LED tube light,it is recommended that 

youu'd better choose wide voltage driver, it can guarantee the stability of output current voltage, ensuring that  LED downlight in the security and stability in the process of use.

LED downlight points of choose and buy 3: light bead quality.

Buy the LED downlight in addition to the need to consider the material and driving power, emphasis must also consider its quality lamp bead, light bead lamp lighting effects depends on the quality,packaging process affects the quality of lamp bead, heat dissipation and other key factors.Sales on the market at presentLED lights,

Have domestic and imported chip, generally different brand, price difference is bigger, lighting effect difference 

also, you are advised to carefully enough to buy.
