Most people do not realize that they have a renewable light source right at their feet. And that is those solar powered lights along the walkway. If you do not have any solar powered sidewalk lights, take a look at a local hardware store, or big box mart – such as wal-mart, lowes and k-mart. They are usually in the garden section.
When shopping for a solar powered light, do not get the cheapest ones on the shelf. But then again, dont go overboard on the price either. There are usually 2 different colored lights – clear and amber. Do not get the amber colored lens, they do not put out as much light as the ones with the clear lens. Be sure to get the lights that use an LED and not a regular bulb.
The way those lights work, during the day the solar cell recharges 2 AA batteries. As the sun starts to go down, a light sensor tells the unit when to turn on. Depending on how much sun light the solar cell got, that defines how much light the unit can provide. The more sun light the cell is exposed to during the day, the longer the burn time at night.
