They chose a residential area inside Denver, Colorado to conduct the study and compared the electromagnetic field (EMF) radiation effects on people living at various distances from high-voltage wires and

The brightness of solar lights is measured in lumens. The output of a bright solar light is about 200 to 400 lumens, while a small pathway light may only emit 10 to 15 lumens. If you're looking to light up an area of your yard so that you can sit outside or entertain at night, we recommend outdoor solar lights that emit at least 200 lumens.
