After fully charged during the day, the 5500mAh battery provides illumination from dusk to dawn.Due to light sensing, the outdoor solar light charges during the day and automatically lights up at night.This wall mount solar light is suitable for any outdoor location, such as front door, back yard, porch, patio, pathway, driveway, etc.With IP65 rating, the solar porch light can withstand most outdoor weather conditions.This solar wall light comes with a 3m (9.8ft) extension cord. The solar security light is available in two mounting modes, integrated and seperated, which can better meet your lighting needs. The seperated installation makes it possible to install the LED lamp panel in a sunless place where you need to light, and the solar panel can be installed where can absorb more sunlight.The Solar Panel and LED Lamp Panel are Adjustable. The solar panel can be rotated vertically to a proper angle so that it can absorb sunlight as much as possible; the LED lamp panel can be rotated horizontally to suit your lighting needs from different angles.Please connect the solar panel to the LED lamp panel, then turn on the switch on the back of the solar panel before testing or installation.The actual working efficiency of solar powered lights is affected by the intensity of the sunlight. Thats mean the weather, seasons, and installation locations will affect the working time and the required charging time of the lights. This is normal for solar lights.The working hours of the solar lights are subject to sunlight intensity and charging time. If you find the solar light works shorter at night or suddenly stops working after a short period of use, a possible cause is insufficient sunlight exposure, especially in September to February when sunlight intensity and daytime decrease. Solution: Relocate the solar panel to face the south for maximum sunlight exposure.
