Misunderstanding of solar LED street light power
Many solar LED street light customers (even some sales staff in the industry) often
use watt as parameters to measure the street light and generally believe that the
higher the street solar light power, the better/ brighter the lamp performs. In fact, this is a huge misunderstanding.
this is a huge misunderstanding.
As we all know, the function of a led solar street light is to emit light. Measuring a led street light should be how much lighting value it has, such as light efficiency, luminous flux, color rendering index, color temperature, and other parameters. The wattage is only the power of the street light, and it is the energy consumption data. If the performance parameters of street lights are the same, the lower the power consumption, the entire street lamp will be more energy-saving, therefore it will last much longer with the same configuration. Otherwise simply buying a street light based on watt will only provide a great opportunity for some inferior products.
In order to avoid this situation, the price per thousand lumens is generally used to measure the cost-effectiveness of LEDs in international. This parameter indicates that the end customer is buying brightness, which is the number of lumens, not power consumption. And this parameter is reduced with the improvement of LED light efficiency, which is also a more scientific parameter.
