LUMii ballasts do exactly what they say on the box.  Other makes may say they produce 400 or 600 watts but when tested produce far less.  Cutting costs and corners with cheap components and materials means they produce less power, less light and thus – smaller yields.

Rest assured, when you use LUMii the power stated is the one you get, no corners cut, just good growing time after time.
