Ø125mm Cool Tube - length 49cm

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 which can suck out the hot air from the light bulb. This prevents a possible heat build-up in the grow room, particularly in small rooms.
Advantages of the Cool Tube

• The 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 ca. 49cm - sockets on the right and left side 125mm
• including E40 lamp socket
