This 45 inch by 42 inch fixture will fit in a 4×4 foot grow space, but it’s really meant for a minimum of 5×5 feet.

It consumes a true 720 watts, placing it in direct competition with some of the other top LED grow lights available, like the ones you’ll read about below. But we believe the GJ720 is probably the best deal right now for 4×4 to 5×5 feet.

This LED grow light utilizes the 4000K SanAn LEDs as well as red 660nm diodes. The diodes are slightly more efficient than the previous generation ones.

In total, the GJ720 uses electricity at a highly efficient rate of 2.8 micromoles per joule.
