150 x 400mm Cool Tube

The latest version of the cool tube has an inner reflector. The total length of the reflector is approx. 50cm.The construction principle of the Cool Tube lies in the glass tube surrounding the light bulb, protecting it from moisture and allowing the connection to an exhaust fan or an activated charcoal filter. This prevents a possible heat build-up in the grow room, particularly in small rooms.Advantages of the Cool TubeThe plants need less distance from the lamp due to the decreased heat Ideal particularly for small and low rooms The exhaust fan can be smaller which saves energy and reduces noise Length approx. 49.5cm - sockets on the right and left side 160mm Cool Tube - Glass ?155mm
