The Cool Tube reflector measures 6" Diameter x 19" long. Cool Tubes offer the most compact and effective way to get bright light over, or in, your growing area. Due to their streamlined design, cooling airflow can move unimpeded, keeping growing area temperatures lower and allowing you to position your lamp very close to your plants. These lamps are also excellent hanging vertically down into the plant canopy or for enclosed growth chambers. This reflector includes a 14" socket cord and 15' extension cord that attaches the socket to the ballast.
