Our lighting systems should be thought of as projection units. Each lighting system unit, or section of “sky”, projects a precise rectangle of light using dual-way linear lenses. Never before used in grow lighting, these lenses are perfect for projecting light both “out” and “down” instead of all-down (spotlight) or all out (no lenses).
1) Light is spread “out” of the short ends of the unit
The 120 degree “wide” angle spreads light over a long distance, creating an even rectangle of light. The wide LED panel gives the plant a large section of sky where light is coming from. With light coming at the plant from multiple angles, more of it is covered with light. This lighting pattern assists in canopy penetration by reducing leaf shadows. In reflective grow areas, the spread-out light near the ends is reflected back into the grow area.
2) Light is focused “down” from the long sides of the unit
This 60 degree “narrow” angle focuses light downwards in a tight beam, intensifying the light output to a smaller area. This increases the density of light the plant receives without reflection. Light in this direction is also not scattered towards another surface, ensuring photons are going down and not lost towards a wall or the floor. This feature also makes it so light is not directed towards your eyes when tending to plants facing the aisle.
The combination of these two properties creates a “widescreen” projection. We can adjust the distance of the light or change the lens focusing power to create the desired size of the lighted area.
