Wavelength ~ HPS A human's visual function has developed over hundreds of thousands of years to operate under the sun, which produces what we refer to as BWL (balanced white light). HPS lamps look yellow to our eyes, being of higher intensity in the 550nm - 625nm wavelengths within our visual spectrum, while being very low in the blues end of our visual spectra, what is referred to as the scotopic range ( 450nm - 500nm). Unfortunately the human eye requires a certain ratio of blue to yellow light waves in order to function properly. The effect of this improper balance is poor visual acuity which is evident in deplorable color balance, a reduced ability to define shapes, increased difficulty in the ability to sense motion, greater eyestrain, headaches, muscular tension etc. Test results comparing our products to the competition with a bare HPS bulb baseline as control clearly show that our lenses outperform the competition across the spectrum in terms of eye protection, even within the UV band where most permanent eye damage occurs. Our HPS ~ Wavelength series offer safety, comfort, style and higher visual acuity at a more affordable price than any of our viable competitors.
