1. Optical efficiency: The same power lamp beads, luminous efficiency is higher, the higher the brightness, the same brightness, the smaller the power consumption, LED downlights more energy efficient.
2. Lamp beads Quality: LED downlight lamp beads quality is determined by the quality and chip packaging technology.
3. Whether the fine work: a good quality LED downlights, except for a few key aspects mentioned above, but also according to different environments, with different technical requirements, such as moisture, dust, magnetic, anti-lightning.
4. Lighting cooling conditions - materials, structures: 8 inch recessed led down light heat is also very important, the same quality of lamps and lamp beads with power factor, if the heat is not good condition, lamp work beads at high temperatures, the light fades will great, lamp life will be reduced.
5. Power efficiency: the higher the better power efficiency, higher efficiency, indicating power consumption LED downlights smaller, the greater the power output.
6. Lamps power factor: power factor is low, indicating that the use of drive power, the circuit design is not good, it will greatly reduce the service life of LED downlights, low power factor, no matter how good the quality of lamp beads, lamp life will not long.
7. Compliance with safety standards: our country LED Lamps safety standards have been promulgated, click to select the safety standards prescribed by the state LED downlight.
8. Drive power Lamps used: the rest of the life of the power LED downlight relatively speaking, much shorter life, the power of life affect the overall life of the lamp, lamp beads theoretical life of 5-10 million hours, but power of life in the 0.2-3 million hours. Power supply design and material selection will determine the life of the power LED downlights.
