This unit comes with the LED light strip ($2,900.00 retail), 2 power packs that connect to one cable box to the light strip, V-Link USB controller ($60.00 retail) to easily set up the lighting to your liking and needs via a laptop computer. There are also 3 red LED auxiliary modules ($100.00 retail each) that were added to the strip and I also have the install tool for the individual LED light pads as well as a brand new set of hanging cables which are still in the packaging. Retail total on this light is $3,260.00. This unit is recommended for aquariums longer than 60” up to 72” long and up to 27” deep tanks. This light grows SPS like crazy, unfortunately I am breaking down my tank and selling some stuff off. I have had this unit for approximately 3 years and has been kept in pristine condition. Local pickup recommended on this in the tri-state area. Located in Northern NJ. Shipping also available and fully insured as well. Asking $1800.00 OBO. NOTE: Some pictures depict prior to red LED modules being installed. Light is fully operational and ready to go.
