By interchanging different diffusion optics you can adjust the angle of light on the ‘X’ axis from 20° to 90°, and the same on the ‘Y’ axis. This gives a range of diffusion optics from 90°x20° to 20° x 90° and everything in-between. By increasing or reducing the height of the grow light above the plants you can alter the size and intensity (but not shape) of the light field
Examples
The 60°x60° diffusion optic is perfect if you wish to focus the LED light into a narrow intense light beam at a low height to finish blooming a mature plant.
A 40°x40° optic is ideal for commercial greenhouse growers who want to hang the light from a high ceiling but still retain high light intensity at plant canopy level.
An 80°x50° provides great coverage for rectangular shape grow rooms. Using two units each equipped with the 80°x50° optic will create superb canopy coverage flowering in a 1.2x1.2m indoor grow tent. Each light will illuminate half of the grow area, and if angled inwards slightly it will maximize light penetration.
