Flag etiquette specifies that a U.S. flag flying after sundown should be lit. The Valley Forge Flag Freedom Light requires no wiring and has two bright LED lights to illuminate your flag—rated 40-lux output. The solar panel is effective even on cloudy days. The solar light goes on/off automatically at dusk/dawn but also has a manual switch. The light has a gooseneck design which allows for tremendous flexibility in pin-pointing the light on the flag. It can be easily adjusted up or down, side-to-side, and also back and forth. This light is ideal to mount onto an off the house flagpole, porch or deck. It can also be used on any in-ground flagpole up to 3" in diameter. The light can also be utilized to illuminate any area around your home such as an architectural feature or even your entrance. Lamp housing is made of weatherproof, durable die-cast aluminum; the gooseneck arm is made of durable stainless steel. Light measures 13.5”x5.5 x 5”, the solar panel measures 5.5”x4”x.25” sq. inches. 90 day manufacturer warranty. Made in China.
