When purchasing a downlight, first look at which material the surface layer belongs to. Common materials used in the market are: iron, die-cast aluminum, aluminum, stainless steel, etc. Among them, the manufacturing price of stainless steel and aluminum is relatively high, but the quality will be relatively good. Different materials and lighting will be different, which can be selected according to the home atmosphere.
2, the lamp beads
The quality of the internal lamp beads is also critical. At present, the LED lamp beads sold in the market are divided into domestic and imported, and only need to be suitable for their own. Different brands of lamp beads, the price difference is large, the lighting effect is also significantly different, it is recommended that you carefully purchase.
3, look at the radiator
It is well known that when the lighting of the luminaire is used for a certain period of time, heat dissipation will begin and the surface temperature of the bulb will also increase. Therefore, when buying a LED downlight, check the quality of the heat sink. The heat dissipation determines the light decay and service life of the downlight. If the radiator is too small, it will cause high temperature to accumulate inside after a long time of work, resulting in a phenomenon of rapid light decay and short life. It is recommended that you buy the aluminum casing, because the aluminum heat dissipation is faster, safer and more efficient.
