"Oh, say can you see by the dawn"s early light"... Or, better yet, by the bright light of theJumbl™ 20-LED solar flagpole floodlight. How proud an American are you? Keep yourfluttering flag illuminated all through the night, and show your true patriotic colors. Now just because you love your country doesn"t mean you have to work hard to honorit. On the contrary, as a red-blooded American, opt for our easy-to-install flagpole light,and show your respect with smarts, not sweat. A precision-cut circular shaft through thecenter of the light allows it to slide onto all standard 15- to 25-foot flagpoles and bepositioned between the edge of the pole and the ball top. Once the ball top istightened in place above the light, you can raise the flag and forget about the lighting. Embedded solar panels atop the device absorb sunlight and convert it to energy topower the LEDs at night. Battery charging may vary slightly based on the weather andthe sun"s intensity on a given day, but even on cloudy days, the solar panels usuallyabsorb enough sunlight for the Jumbl™ LED flagpole light to function just fine. Measures 7.9 inches in diameter, and 1.5 inches in thickness. Casing is made of highqualityflame-retardant ABS plastic, and may be left on flagpole year-round in allseasons.
