Bests & Worsts Reviews from Amazon

This light is very bright if you face the LEDs toward the table. And it gently illuminates the underside of a patio umbrella if the LEDs are faced up and at its highest power. Holds well to a wooden umbrella pole and is very easy to operate the latch that allows you to remove or install the light onto the pole. Batteries last a good long time in this light. Highly recommended. Update: July 23 2017 another customer asked if these would fit his umbrella pole with a diameter of 2.5 inches. I measured it with my calipers and the maximum pole diameter would be an inch and a half.
