The Gen 2 Slimline Designer Bracket is the latest mounting system, designed and manufactured by D-D The Aquarium Solution for the new AI Hydra 32HD & Hydra 64HD LEDs. The Gen 2 Slimline Designer Bracket has been modified to allow it to fasten directly to the top of the lights. The Gen 2 Slimline Designer Bracket now allows you to slide the light back and forwards to cope with different widths of tank and also rotate so that the lights can be positioned along the length or across the width of the aquarium.
