The Dual Max Tube Expander is an updated version of the Dual Cool Tube that includes an adjustable wing reflector around the cool tube. Some added benefits of this reflector are the concentrated, directed lighting options for growing.


The reflector features independently adjustable wings that can alter the lighting footprint to better suit the users growing area. It also helps to further shield the surrounding area from the hot, high intensity discharge growing bulbs.


The entire system is designed to be connected to an air cooling system which keeps the heat that plants are exposed to very low. This allows for closer light positioning and improved growing efficiency. The Dual Tube utilizes 2 growing lights in a single tube, allowing the user to double the lighting power and coverage area for growing. It is great for covering a lighting area up to 4’ x 8’.
