MEGA LED Light Bar is designed for rear facing use to illuminate the entire bed and rear work area. The 40" all-aluminum crossbar is mounted to bolts between the bed and cab of your truck with aluminum brackets. Drilling may be required on some vehicles. The total weight is under 10 lbs. The MEGA Light Bar is powered by five LED Pods each generating 8,000 Raw Lumen or a total of 40,000 Raw Lumen. Increased by its prismatic reflective technology, the actual effective luminosity was further amplified by 20%, making this the most powerful rear facing light bar in existence. Makes a powerful statement not only in terms of raw Lumen, but also in a record low AMP draw of only 14.5 Amp at 175 Watt of energy.
