BEWARE! These lights are NOT "battery powered." The "battery" MUST be charged by the sun -- 6 to 7 hours of direct summer sun, or 8 to 9 hours of direct winter sun -- in order to work. I bought these lights because the description misled me to think these could be powered by either insertable batteries or the sun. They cannot. If you are looking for a spot that does not get direct sunlight, these lights will not work.
