第一，看看该灯具是否采用国外进口的芯片，光谱会比较好。第二，看看灯罩是否结实，光滑，防止摔坏漏电。第三，看看散热效果是否好，现在市面上散热效果比较好的是采用陶瓷外壳，绝缘导热，比普通的铝基板散热效果好十倍。第四，看看是否含有电解电容，电解电容会影响灯具的寿命的。第五，看看是否频闪，在这里教一家一种鉴别是否频闪的方法，可以拿自己的手机进行拍照鉴定。

First, to see if the lamp is imported from abroad, the spectrum will be better. Second, let's see if the lampshade is strong and smooth, and prevent leakage. Third, look at the heat effect is good, now the market on the better heat dissipation is the use of ceramic shell, insulation heat conduction, compared with the ordinary aluminum substrate heat dissipation ten times better. Fourth, to see whether there is electrolytic capacitors, electrolytic capacitors will affect the life of lamps and lanterns. Fifth, let's see if it is flicker. Here we teach a family how to identify flicker.
