Although solar street lights are very common, it is almost a customary thing for solar street lights to be equipped with Led street lamp heads, but many customers still do not understand the difference between LED street lamp heads and traditional sodium lamps. Today, the street lamp manufacturer Sanhao Lighting will tell you.
Last week, a customer inquired about the price of our solar street light, saying that it was a 100-watt LED street light head. Our salesperson asked him how many meters the light pole was, and the customer said it was 6 meters. Generally speaking, the brightness of 6 meters, 30 watts and 40 watts is already very bright. How can customers ask for a 6 meters 100 watt led street lamp head? After understanding, the original customer thought that the LED street light was not much brighter than the sodium light, so it should be bigger.
So how much brighter is the LED street lamp head than the sodium lamp? Generally speaking, the brightness of LED street lamp head is 2.5 times that of ordinary sodium lamp. The light efficiency utilization rate of sodium lamp is very low, only about 65%, because its general light needs to use reflector to emit light. Therefore, the energy saving of LED is about 60-70% than that of ordinary sodium lamp.
If the requirements for solar street lights are not particularly high, the configuration of 6 meters 25 watts and 5 meters 20 watts can meet the lighting needs.
