How to judge the quality of heat dissipation?

- Sep 19, 2018-

Many people use the most “easy” method when choosing lamps. Turn this light on for a while, then touch it with your hand.

 

Some people say ,”my lamp is very good, the surface temperature is only 27 degrees.” Is this reall true? In fact, when the LED light works normally, the temperature of the radiator will be low. But it will not reach a temperature of 27 degrees. In addition, you feel this temperature is only the temperature of the outer heat sink. So even if the surface temperature is low, it is definitely good.
