THIS ITEM HAS BEEN DISCONTINUED This LED light system easily outperforms other LED lighting systems that require up to 150W. The Haight Solid State PPF-400 only conusmes a mere 90W while far outperforming other lights in its class. Some LED systems have a power consumption that can be misleading as they employ fans that may use up to 40W of additional power. Other poplular LED grow lights use upto three times more individual LED's lights and draw up to 120W of power and reqire a fan yet they produce 10% less light than the PPF-400. Another well know LED light draws 90W of power yet the output is less than half of the light of the PPF-400.
