Factory lighting why use high-pressure sodium lamp, what are the advantages?
Low discharge voltage, high brightness, color temperature 3000K. (compared with a metal halide lamp)
The sodium lamp has higher light efficiency than the metal halide lamp, but its color rendering is poor. Look at the factory requirements, but now the trend is slowly replaced by high-power COB packaged LED lights.
You should be wrong, the factory lighting is generally metal halide lamp, OK?.Sodium light is generally used for street lighting and agricultural lighting.
