Before we use 200w outdoor slim led floodlight, we must first choose 200w outdoor slim led floodlight, then what is the quality of 200w outdoor slim led floodlight?
1, light attenuation is good, 200w outdoor slim led floodlight has less than 30% attenuation before 25000 hours, the main factor affecting light attenuation is the difference between light source quality and heat dissipation structure.
2, the light effect, that is, lm / w per watt, he is the reflection of the power-saving performance of the lamp, the better the power-saving lamp, the higher the light effect. At present, the efficacy of LEDs and compact fluorescent lamps is almost the same.
3, light source, led200w outdoor slim led floodlight with high-power LED as a light source, expensive, and straw hat or piranha LED price is very cheap, and not suitable for lighting.
4, the drive power, a good drive power can guarantee the life of the entire lamp, led200w outdoor slim led floodlight has a theoretical life of 100,000 hours, while the general drive power life is less than 100,000 hours. To ensure the life of the entire lamp, the drive power is also a key link. On the other hand, the high power 200w outdoor slim led floodlight must be driven by a circulating fan constant current. If low-cost constant-voltage driving is used, the life will be shortened.
