Maxspect Razor R420R 320 watt 15K Lighting System - 78 individual LED's, Perfect for 48" Tanks. Includes all original hardware and documentation in original box. Only used 1 year. Purchased in Dec of 2015 and started using in Jan of 2016. Everything works wonderfully. Awesome light! I took the tank down and I no longer have a use for this light so I might as well sell it to someone who can use it. - $600 shipped (Originally paid $900) (shipping to the continental U.S. only please)
