Does the wattage of the street lamp have anything to do with the installation height of the lamp? And how can the utilization factor of high pressure sodium lamp be obtained?
There is no rigid height requirement, but the installation height of 250W is best over 8 meters, and the installation height of 400W is better than 10 meters, which is purely personal experience.The utilization coefficient of high pressure sodium lamp is generally between 0.3~0.5. Usually take 0.4
In fact, there is no height requirement, mainly the calculation of illuminance and uniformity! The coefficient of utilization is about 0.38 or 0.4.If you want to know more pictures, you can ask me again
Yes, of courseUnder normal circumstances, such as: 6 meters below the 150W sodium lamp8 meters with 250W8 meters or more with 400WThe sodium lamp is currently recognized as my utilization factor of 0. About 6, decrease with the guidance
