These lightly used, LED grow lights are powerful and energy-efficient. They each cover a 3.75' x 3.75' footprint for vegetative growth and 3' x 3' for flowering.
They are the most effective and productive lights I've ever used with red & blue wavelengths for maximum plant growth. And you'll barely notice your electric bill.
I'm meticulous with my equipment, these are both in their original packaging. Used for just 7 months and still in excellent condition.
The other features I love:
-Ratcheting light hangers for easy adjustment as your plants take off
-Built in cooling fans (although the lights do not get warm like an HPS would)
