All reflectors are not created equal.
The Commercial Series comes with an assortment of interchangeable reflectors ranging from a narrow 108° to 155° wide-angle beam pattern. These include the open open-style and wing-type reflector pictured below.
Some are best for mother rooms, some are best for large commercial facilities and some work best in sea-of-green type cultivation methods.
They all are made with 97% German reflective material.
