LED street lamps and sodium street lamps are different in color temperature, CRI, and illumination uniformity.
- Color temperature: The LED street lamp usually has a higher color temperature than the sodium street lamp. So they look white most of the time, while sodium street lamps look yellow.
- CRI: LED street lamps have a higher CRI than the sodium street lamp. So under LED light, you can see more clearly.
- Illumination uniformity: LED street lamps have a special light distribution design, making the light shine on the road uniformly. Some of the light from the sodium street lamp won’t shine on the road, causing energy waste.
