Our factory specializes in engineering light sources, mainly targeting outdoor street lamp light sources. Our products are positioned in the mid-to-high end range, ensuring stable quality and avoiding the problem of difficult maintenance when outdoor light sources are damaged. This product is a solar system light source, suitable for direct use with lithium iron phosphate batteries. The input voltages are 3.2V/6.4V/9.6V respectively. The E27 screw installation method is adopted, which solves the problem of troublesome later maintenance of the integrated solar light source and street lamp pole.
