The quality of LED lamps mainly depends on several parameters :
1. Luminous decay, better LED lamps have luminous decay <30% before 25000 hours; LED Street light housing ,led flood light housing ,100w led street light supplier and factory in china; 2. Luminous efficiency, which is the number of lumens per watt, in LM/W. It reflects the energy-saving performance of the lamp. The better the energy-saving lamp, the higher the luminous efficiency. With the improvement of LED luminous efficiency, CREE may produce 186lm/w light source this year. LED Streetlight , ip66 led street light empty casing factory in ningbo; 3. The light source is high-power LED, straw hat lamp or piranha-type LED; LED lighting fixtures use high-power LED as the light source, and the price is relatively high; while the price of straw hat lamp or piranha-type LED is very cheap and not suitable for lighting The light source of class lamps. led tunnel light ,200w led floodlight ,100w led road lighting. 4. Drive power. A good drive power can guarantee the life of the overall lamp. The theoretical life of LED is 100,000 hours while the life of general drive power is less than 100,000 hours; in order to ensure the life of the overall lamp, the drive power is also a key part; On the one hand, the LED must be driven by a constant current, if a low-cost constant voltage drive is used, the life of the LED will be shortened.
