Ion Crystal coating transforms white light into amber light without diminishing the strength of the beam. Ion Crystal technology allows as much as 95% of the light produced by the bulb to pass through, compared to as little as 65% through dyed glass. The long wavelength Plasma Ion beam reduces refraction for dramatically increased visibility in snow, rain, and fog.
