This document summarizes the specifications of 60W and 90W solar street lights. The 60W light produces 6600 lumens with a 1200 beam angle and operates for 12 hours. The 90W light produces 10800 lumens with the same beam angle and operation time. Both lights illuminate different surface areas and lux levels depending on the height, from 4 to 10 meters. The 60W light uses a 250Wp solar module, 85Ah batteries, and a 10A charge controller. The 90W light uses a 180Wp module, 120Ah batteries, and a 20A charge controller.
