Enjoy growing with no more heat problems and the extra lumen output that you get by being able to place your lights far closer to your plants.
Cool Tube reflectors can be linked together with 3, 4 or 5 way splitters into the ducting to allow venting to multiple rows of shades using only one 250mm centrifugal fan.
Not only do you vent out all the heat generated by the globes but you can now place your globes much closer to your plants.
They are also perfectly suited for "under 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!
