400W high pressure sodium lamp can replace 150WLED lamp? Luminous flux?
LED lamps instead of high pressure sodium lamps.
The life of LED street lights is much higher than that of high pressure sodium lamps, which are generally replaced by LEDLuminous flux comparison, it must be high sodium light, but the light efficiency of sodium lamp utilization is not high, many light is invalid, but also poor color rendering, LED generally do white light, see clearly, bright
Yes, and under the current technical conditions, the life expectancy of HPS is much longer than that of LED street lamps
