Why 94% reflectance matters:
Every time a light ray (radiant energy) contacts a
surface, a portion of the energy is absorbed and a portion is reflected, but
there is no energy loss. Materials that reflect significantly more radiant
energy than they absorb are considered reflective. ORCA Grow Film® is
94% reflective across the full visible spectrum, or it only absorbs 6% of the
radiant energy. Reflective materials are used to increase the overall effective
coverage from the grow lights in a grow room. When you cover the walls,
ceiling, and floors with a quality reflective material you can increase the overall
efficiency of the grow room by 30 to 75 percent.
All grow room layouts and designs involve multiple reflections/light bounces
due to corners, angles, and static objects in the grow room. A high performance
reflector will minimize absorbance from multiple bounces and maximize the
usable exiting light. A small difference in reflectance can make big
difference for a grow room’s total lighting efficiency.
