Incredible PAR Footprint For Only 510 Watts

The HGL 550 only consumes 510 watts, but gives you the output of a 1000 watt HID system or LED lights that consume 600 to 700 watts.

This is the PAR footprint hanging in a grow tent at 22 inches, over a 4 by 4 foot coverage area.

And these are the PAR footprints in an open space, first at 18 inches, then at 24 inches.
