What it Can DoThe solar lantern lights are designed mainly for outdoor lighting and decoration such as backyard gazebo deck and courtyard, but you can also charge the lights outdoors then use as indoor lamp because you will get a very pretty accent lighting. How it WorksWhen you receive the garden solar lights, you need to TURN the switch into the "ON" position and place the solar panel in direct sunlight to charge for 6 ~ 8 hours in the daytime, then the illumination time will be up to 8 hours at night time. Note for ChargingPlease make sure that the solar panel is located in an outdoor area where it can get at least 6 hours of sunshine each day. Shady locations or bad weather will influence the battery's charge and shorten the working time. Stay away from other light sourcesThe solar panel of the solar yard lights should NOT be placed near other light sources as the LED may be very dim or not work at all.
