Cool Tube
Other ManufacturersDescription
Cooltube is an hermetically sealed reflector that keeps hot air produced by the light bulb insulated, making it possible to have a stable temperature in grow tents as well as to make the most of the available light.
Making use of an extractor may be highly beneficial so that the tube remains cold. It can be attached to your usual lighting kit, taking advantage of the bulb and the ballast.
It comes in two sizes: 120cm and 150cm.
