30w To 300w Waterproof led light led Street Light 3000K 140lm/W assorted with 8m 10m 12m light pole CE certificate

advantages

1. Its own characteristics -- unidirectivity of light, no diffuse light, to ensure lighting efficiency.

2, LED street lamps have a unique secondary optical design, the LED street light to the required lighting area, further improve the lighting efficiency, in order to achieve the purpose of energy saving.

3, LED has reached 110-130lm/W, and there is a lot of room for development, the theoretical value of 360lm/W. However, the luminous efficiency of high pressure sodium lamp increases with the increase of power. Therefore, the overall luminous efficiency of LED street lamp is stronger than that of high pressure sodium lamp. (This overall light efficiency is theoretical; in fact, the light efficiency of high-pressure sodium lamps above 250W is higher than that of LED lamps).

4, LED street light color rendering is much higher than high pressure sodium lamp, high pressure sodium lamp color index is only about 23, and LED street light color index reached more than 75, from the perspective of visual psychology, to achieve the same brightness, LED street light illumination can be reduced by more than 20% than high pressure sodium lamp on average.
