theres a big difference in quality leds and cheaper ones. Drivers, diodes, materials used, and not to mention customer service. They get the “1200” watts by say this shitting diode is 3watts x115 or whatever. However they know they can’t drive those shitty diodes anymore then .3 to .5 watts per getting an actual watt of 45 watts or whatever. You need true watts and figure your space based on that. the upfront cost is higher however overall cost comes down In the form of power usage, ac requirements, ending product is better in every aspect. In one grow your ROI is already there IF you can grow. these companies are what gave leds a bad name. Claiming 4000 watt lights pull 150 watts and ppl wondering why they got dismal harvest.
