While LED lighting is all the rage across a number of industries, for years some industries have been “singing the blues” when it comes to LEDs.

That’s because almost all existing LED lighting creates harmful blue-spectrum light that can result in photochemical degradation and photo-oxidization. Pharmaceutical and semiconductors manufacturers, for example, cannot expose many of their products during manufacture to harmful blue-spectrum light. Dairies have seen blue light degrade critical proteins and vitamins and produce undesirable flavors in milk, and for years breweries have known that blue light can contribute to the production of compounds that can make beer taste and smell “skunky.”

Production facilities have traditionally used colored packaging and UV coating solutions on lamps to block the harmful blue light, but now Hubbell has introduced the first LED highbay luminaire specifically designed to suppress blue spectrum light. Called the SpectraLoc, the new lamp does so by converting harmful blue light under 500 nanometers to green and yellow light.

Joe Engle, product manager for Hubbell Industrial Lighting, says the new fixture opens the door for these industries to the cost savings and associated benefits of LEDs that others have been reaping for years.

Engle says the SpectraLoc can exceed 19,000 lumens while only consuming 112-175 watts, decreasing the amount of energy required to power the lights, offering cost savings. Next, LEDs famously outlast many other types of lighting, lowering maintenance and lamp change-out costs. Finally, Engle notes that it is common in many industrial settings to find traditional light sources — high pressure sodium, metal halide and fluorescents — working harder than they should to ensure a safe working area.

“What is the point of covering up a new LED highbay with a UV coating if it’s going to add to the power consumption of the fixture itself?” Engle asks. “Not only will the SpectraLoc cost less to operate, its performance will be more efficient than the previous luminaire.”

And though Engle didn’t exactly say it in so many words, perhaps also reduce instances of vitamin-deficient milk and skunky beer. Nice.
