Product description

The Cooltube 150 is a specially designed reflector, in which the lamp lights within a glass cylinder. The glass cy-linder is necessary, because it provides cooling and ventilation to the lamp, which in turn leads to a reduced heat development within the grow room.
Cooltubes have many benefits, just to name some, they allow you to position the lamp way closer to the plants than you could without a Cooltube, which results in a higher per square absorption of light.
