An advanced ‘Optic DriveTM’ technology captures and focuses more of the light generated to produce an extra-penetrating light output and eliminate waste. The result is 30% brighter light output than compared to a conventional LED light bar of the same length. Light bar contains Osram high power LEDs in a one-piece die-cast aluminum housing with 580mm pre-wired lead, genuine Nitto breather vent and weatherproof DT connector.
