75% of the energy consumed by an LED becomes heat.
25% of the operating expense is energy cost.
LEDs do not replicate the solar spectrum.
Track the sun to concentrate the sun's rays. Filter heat-generating radiation to deliver cool light.
Offset energy cost by at least 50%.
Funnel the sunlight into optical fibers and route it's energy indoors for plant use. This delivers full-spectrum sunlight for higher quantity and quality per yield.
