Powerful, agile and efficient. The twin heads on this flood light can each secure a 180-degree arc, saturating your property with 3000 lumens of 4000K bright white light using only 30-Watts. Installation is hands-free using the universal junction box mounting plate included with the fixture. You won't even need tools to customize the angle of heads to your space. The die-cast aluminum housing is impact- and weather-resistant, with dusk to dawn photocell sensors that automatically turn the light on at nightfall and off at first light. Expect 50,000 hours of maintenance-free use, while the LED bulbs save about $40 a year on utility bills, well beyond PROBRITE's 5-year warranty.
