2. Looking at the light effect, if the led high bay light uses the same lamp beads, the higher the light efficiency, the higher the brightness; if the lighting brightness is the same, the less power consumption, it means the led high bay light more energy efficient;
3. Looking at the heat dissipation, if the lamp bead is at high temperature, the light decay will become very large, which will shorten the life of the led high bay lamp, and will also affect its lighting effect;
4. Look at the quality of the lamp beads used, because the quality of the lamp beads directly determines the quality of the LED high bay light, and the quality of the lamp beads also determines the quality of the chip and packaging technology;
5. The observed power factor, the lower the power factor, the better the driving power and circuit design settings used by the led high bay light, which will greatly reduce the service life of the led high bay light.
