16 inch radius installed
Included: 
 
3 full spectrum lights, (54w, 6400k, 48 inch) from Sun Blaster.
Our custom designed, 3D printed Light Ring Kit made of pla filaments.
 
Designed and printed in house.
 
This simple little element fits over the top of your tower insert allowing you to attach and suspend your lights.   Eliminates the need to wall hang and allows even/adjustable light exposure.  The additional spaces in the suspension bar mean you can keep the lights closer while your plants are small, and move them out to accomodate growth.  SO simple - yet SO helpful.
