Pros And Cons Of MH Street Lights
Jun 11, 2018

The biggest advantage of the MH street light is its high luminous efficiency, its luminous efficiency of up to 80 to 90 lm/W, and its low calorific value during normal lighting, so it is a cold light source. Since the spectrum of the MH gas discharge light superimposes a dense linear spectrum on the basis of the continuous spectrum, the color rendering index is particularly high, that is, the color reproduction is particularly good and can be more than 90%. In addition, the color temperature of the MH street light is as high as 5000 ~ 6000K, and the special projection lamp can reach 7000 ~ 8000K. Under the same brightness conditions, the higher the color temperature, the brighter the human eye feels.


MH street light have high brightness, small volume, and short relative life. Due to the limitations of materials and technology, domestic MH street light have a life expectancy of less than 1,000 hours, and imported MH street light have a lifetime of thousands of hours.


Another disadvantage of MH street lights is that they are difficult to start and special triggers must be used. After starting, the brightness gradually increases. If the start-up energy is too high and the start-up speed is too fast, this will affect the life of the lamp and should be fully considered in the circuit design.
