NaturaLux™ Filters absorb a portion of the yellow and green light rays in order to provide a full spectrum of light from ordinary cool white fluorescent light bulbs.  By absorbing the high yellow/green content of fluorescent light and allowing more of the violet, blue, and red portions through, we are able to transform the color output of ordinary cool white light into virtually the same color output found in natural sunlight.

UV Absorption

All visible light and ultraviolet (UV) light is measured in nanometers (nm).  Fluorescent lighting requires the use of UV radiation to produce visible light.  UV is present in three wavelength ranges:  UVA (320 to 400nm); UVB (280-320nm); and UVC (100-280nm). NaturaLux Filters absorb 100% of UVB and UVA up to 380nm. From 380nm to 390nm, they absorb 80-99% of UVA. From 390nm to 400nm, they absorb 50-80% of UVA.

Clear Acrylic Prismatic Lens

As you can see in the above photos, the Clear Prismatic Lenses, found in any home improvement center, allow at least 40% of UV rays to pass through.

NaturaLux™ Parabolic Overlay Lens

The NaturaLux™ Parabolic Overlay Lens absorbs almost 98% of all UV rays.

NaturaLux™ Filters absorb twenty times (20X) more UV than ordinary clear prismatic panels, providing far more UV protection!
