Cool Tube Reflectors can lower temperatures in the growing environment by up to 10 degrees.

Simply join one or more cool tubes together with 150mm ducting and a fan, and you can blow most of the hot air created by lighting straight out of the growing environment. The heat from the lights doesn’t get a chance to warm anything up!!

The use of Cool tubes allows you to place your globes much closer to your plants without any burning. This in turn increases lumen exposure, resulting in much larger yields.

They are also suited for floor lighting. Growers can position them upside down with the light shining up underneath the plants. The globe is fully shielded within the glass tube and all heat can again be vented straight out of the room!

Setup
Cool Tubes are easy to setup, simply mount your shades above (or below) your plants and join together using 150mm ducting. Mount a fan at one end and blow air through the tubes and exhaust it out the other end – no hot air can escape into the growing area. It is important to blow the air along the tubes and to not suck the hot air through the fan. The extra heat forced through the fan could cause it to overheat and fail.
