1. To see the use of the lamp drive power, power supply life relative to other parts of the lamp, the life is much shorter, the life of the power supply affect the overall life of the lamp, lamp beads of the theoretical life of 5-10 million hours, and power Life expectancy of 0.2-3 million hours, power supply design and material selection will determine the power supply life.

2. See the light effect. The same lamp bead power, the higher the luminous efficiency, the higher the brightness, the same brightness, power consumption, the more energy-efficient.

3. See power efficiency, power efficiency, the higher the better, the higher the power itself, the smaller the power consumption, the greater the output power.
