The HPS & MH 400 watt Air Cooled Tube Complete System contains all the components you need to start lighting your grow immediately. The cool tube is the most flexible and compact HID grow light reflector.

It can hang horizontally or vertically, so you can get a bulb anywhere you like. Plus, you can vent the heat out, ensuring none of it enters your grow room. Two versions are available: one with 6 inch flanges and one with 8 inch flanges. Please select the size you want above.
