Industrial lighting system converts blue light to green, yellow

Companies that produce milk, beer, pharmaceuticals, and semiconductors have been wary to adopt LED technology because the blue-light wavelength causes photochemical degradation and photo-oxidation damage to the products being made.

These industries have had to use colored packing and UV coating solutions, which can increase power consumption and energy costs, to protect against the harmful blue light. New lighting technology from Hubbell Lighting looks to solve the problem. The SpectraLoc LED blue-spectrum high-bay fixture converts harmful blue light under 500 nanometers to benign green and yellow light. The light applies what is called the Stokes Shift effect, where wavelengths of light below 500 nanometers are absorbed by a unique optic found in SpectraLoc and are then retransmitted at longer, nondestructive wavelengths.

SpectraLoc can exceed 19,000 lumens while only consuming 112-175 watts, averaging 108 to 110 lumens per watt.
