FAQ

1. How to choose a street lamp？

In addition to thermal management, make sure that the street light you choose has:

Recyclable, tested materials.
Wide enough power range.
Wide optical spectrum.
Replaceable components.
High IP & IK rating.
Long-term guarantee.
Smart City Compatibility.

2. What is intelligent or smart street lighting?

Smart street lights refer to public street lights that adapt to the movement of pedestrians, cyclists, and cars in smart cities. Also known as adaptive street lighting, it lights up when it senses activity and dims when it doesn't. This is different from traditional fixed lighting, as well as dimmed lighting on a timer.

3. I heard that color temperature affects the efficiency of street lighting. What are the differences between CCTs?

Color temperature is a crucial component of color appearance that determines how "warm" (yellowish) or "cool" (bluish) white light looks on paper. A warm light is approximately 2,700 degrees Kelvin (K), neutral white is approximately 4,000 K, and cold white is approximately 5,000 K or greater. Correlated Color Temperature, or CCT, is specified in degrees Kelvin. When compared to the enormous efficiency benefits made by switching from conventional incandescent to LED lights, the energy efficiency variations between colder and warmer color temperatures are very insignificant.
