First of all, it is necessary to disassemble the shell of the transformer to see the size of the circuit board and coil inside, and the arrangement of components should be thinner to enhance heat dissipation. Note that the size of the coil determines the brightness and life of the spotlight.

Lamp cup

High-quality lamp cup adopts vertical structure, ordinary lamp cup adopts horizontal structure, and the other is the spotlight of the lamp cup, because the spotlight is for directional lighting, so the spotlight is very important. It can be compared by two light cups.


The light efficiency of the spotlight is reflected in the power factor, the greater the power factor, the better the light efficiency, the ordinary spotlight power factor is about 0.5, the price is cheap, the power factor of the high-quality spotlight is 0.99, the price is slightly more expensive.
