The solar cell pendant Solia illuminates with three choices of lumen mode (50, 200 and 500 lumens). The solar cell lamp is made of stainless steel on the bracket and chain, as well as ABS plastic on the lamp shade. It is easily placed on your patio or balcony. To start the solar cell lighting, you first turn on the switch that is under the lamp shade, then you control the strength of the lumen with the hanging switch. Place the solar lamp so that the panel receives direct sunlight during the day to best charge the included batteries.
