Lumii Black 720w/960w LED

This LED grow light fixture has a stunning operating efficacy of around 2.9 µmol/J, and is built using LED chips with individual efficacies of 3.4 - 3.7 µmol/J. It’s maximum PPF output is an impressive  2596 µmol/s when powered at 960 W (by two ballasts each drawing 480 W). 

The flexibility of this LED unit is unrivalled, it can be run as one complete unit with one ballast making it run at 720w or 2 x ballast set at 400w to achieve a total output of 960w. You can even split the unit and run it separate as 2 x 480w units units powered by one ballast each making it easier to fit into smaller spaces and fill gaps in rooms where you couldn't fit a full sized unit in.
