A great way to hang your AcroOptics grow lights, the CamJam XT by Nite IzeTM is one of our favorites. A carabiner-style connector with a thumb-activated release allows you to raise or lower your fixture easily. Use two sets for a four-point anchor to hang, raise and lower your fixture as needed. Simply tie off the loose end to one fixture hanger and connect the biner to the opposite hanger, and you are good to go.
