This solar pathway light has a sturdy copper housing and turns on automatically at night, but doesn't need costly underground wiring. The lamp incorporates a crystal column lens whose beveled glass enhances brightness, and a copper canopy that directs a narrow curtain of light low over the ground without blinding passersby. A high efficiency monocrystal solar panel (the same technology powering many NASA satellites) recharges two NiCad batteries (included) that illuminate two bright white LEDs. After a day's exposure to sun, the light operates 8 to 10 hours. Battery is rechargeable up to 500 times (about a year and a half). The copper will achieve an attractive patina over time. Stakes easily into ground. 15 1/2" H x 6" Diam. (2 lbs.)
