Plasma Ion coating transforms white light into amber light without diminishing the strength of the beam. Plasma Ion technology allows more than 97% of the light produced by the bulb to pass through, compared to as little as 65% through dyed glass. The long wavelength solar yellow beam reduces reflective glare for dramatically increased visibility in snow, rain, and fog. Stock Wattage 60/55w produces equivalent of 130/120w conventional bulb using Xtra technology.
