It's simple. High yields， low heat and less electricity . Supplement sunlight， especially in winter months when daylight hours are short. . increase the length of the "day" in order to trigger specific growth and flowering and help plants grow quicker ， decrease growth circle . Warm to touch -- won't burn plant . No high wattage cooling systems needed ， 50%-70% savings in energy costs . 2016.1.7
