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!
