The light from each LGM light bar is emitted in a cone shape as
pictured to the right.   Mounting the bars too close to plants (closer
than 18") will prevent the light from individual clusters from blending
properly before reaching the plant canopy.  If bars must be mounted
closer than 18in- use the "close mounting" recommendations to the
left.  While coverage area increases as you move LED grow lighting
further from the plant canopy, the light intensity decreases.  When
using multiple light bar arrays, increasing the distance from the plant
canopy allows clusters from multiple light bars to overlap.
