LED lighting that will pass the test of time. ETERNALUX LED light bars are the most advanced LED light bars on the market for any application. Built with an industrial grade aluminum housing with Zero Line dlffusion™ lenses for anti-glare and undlstorted light emissions, these light bars are engineered with the latest generation of LED light engines capable of lasting 50 years– an industry first! The secret to the LED light engines’ generational life expectancy is the remote phosphor built into the Zero Line dlffusion lenses, unlike tradltional LEDs when the phosphor is baked into the dlodes. This unique patented design around heat management eliminates the number one reason for premature failure of LEDs - heat, all while providlng consistent true to life color rendering and a lifetime of performance.
