The Economy Cool Tube system comes complete with the 19 inch Cool Tube. 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. The tube measures 19 inches long and has a 6 inch diameter. The Xtrasun ballast is extremely efficient and reliable. It boast a 5 year warrant, the best in it's class. The standard HPS bulb comes with a 1 year warranty. We also include a 15 foot cord that connects the 14 inch socket cord to the ballast.
