【 Solar street lamps factory 】 LED lights can both environmental protection and save electricity, why can't spread instead of high pressure sodium lamp?
In the current technology seems not correct. LED general lighting for 30 - currently on the market 100 lm/W, and high pressure sodium lamp light efficiency is 80 - 150lm/W。 In addition a master also mentioned the life span of the LED and other prices, this is the key factors restricting the popularization of the LED street lamp

LED has many advantages, of course. LED using dc, natural match, and photovoltaic panels are on the market can already see a lot of photovoltaic + LED street light. In theory, the LED street light, white LED luminous efficiency is highest can be 300 lm/W, technically still has a lot of room to improve, compared with sodium lamp is hard to improve. In addition to the LED compared with sodium lamp has higher color rendering index. Believe that as technology advances, the LED will gradually replace sodium lamp.
