This 14 watt multipurpose blue & white LED light panel is extraordinarily bright and encompasses the absolute latest technology; its sixth-generation design is drastically more efficient, and produces the highest lumens of any competing LED panel of the same wattage. Each panel contains 225 genuine Bridgelux LEDs: 112 white, 113 blue (6 centiwatt, 5mm). These tight-tolerance LEDs feature a truly optimized spectrum for unrivaled chlorophyll, carotene, and xanthophyll light absorption. They are wide-angle bulbs to provide maximum coverage and output, and are mounted on a silver-reflective board to further increase efficiency. They run on built-in, ballast-free, power supply circuitry and run cool because they don\'t use filaments. The PC board has oversized, 1/4\" wide traces for minimum loss, and the composite frame has pre-drilled holes for easy mounting and hanging. Operates on 110-120 volts with a standard USA power cord. 10-year or more life expectancy. CE & ROHS compliant. Dimensions: 12.25\" square x 1.5\" thick. Blue wavelength: 455 nm. Kelvin Color Temperature: 12,000K. Recommended coverage: 4 square feet.
