Patio Umbrella Lights - 24 LED Lights To Really Brighten Your Outdoor Patio or Camping Area - 3 x AA Battery Operated - Adjustable to Fit Around Your Umbrella Pole NEW AND IMPROVED POLE CLIPS - After many comments about the pole clips breaking at times, we've made a HUGE UPGRADE by strengthening these with thicker inner clips for extra strength. 33 FOOT LIGHTING AREA - At its peak height, this Umbrella Light using 24 LEDs at 72 Lumens (a measurement of light output) can cover an area of 33 feet in diameter. RUNS ON 3 x AA BATTERIES - Commonly available batteries which can be purchased anywhere. This Umbrella Light was tested using standard batteries and lasted for approximately 6 hours, but further testing has shown that long lasting batteries allow for a much longer usage time. VERY LIGHT WEIGHT - Weighing only 11 ounces, this unit does not add any unnecessary weight to your Patio Umbrella. COOL WHITE TEMPERATURE (CCT) - This light color gives off a cooler perception than Warm White or Natural White which is perfect in summer months. This temperature light also reduces the likelihood of insect attraction (as compared to lanterns and torches).
