Options include interchangeable wall washer, round apertures, output from 500-2000 lumens, and choice of color temperatures.

Judges comments

The judges appreciated the Calculite's appealing square pattern, wide distribution and heat sink design, but have some concerns about color shifts at the edge of the beam pattern.
