1. Look at the overall “power factor of the luminaire”: the power factor is low, indicating that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the luminaire. The power factor is low, and the life of the lamp using the lamp bead is not long. .

2, look at "lighting conditions - materials, structure": LED lighting is also very important, the same power factor lamps and the same quality of the lamp beads, if the heat dissipation conditions are not good, the lamp beads work at high temperatures, the light fade will be very Large, the life of the lamp will be reduced.

3, look at "light quality": the quality of the lamp is determined by the chip quality and packaging technology.

4. Look at the driving power supply used by the luminaire. The service life of the power supply is much shorter than that of other parts of the luminaire. The life of the power supply affects the overall life of the luminaire. The theoretical life of the lamp bead is 50,000-100,000 hours. The life span is 0.2-3 million hours, and the design and material selection of the power supply will determine the service life of the power supply.

5, look at the light effect: the same lamp power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the smaller the power consumption, the more energy efficient.

6, look at the power efficiency, the higher the power efficiency, the higher, the higher the power consumption of the power supply itself, the greater the output power.

7. Is it to see if it meets safety standards? China's LED lighting safety standards have been introduced, please select LED lamps according to the national safety standards.

8, is to see if the work is fine.
