6" x 40cm Long Protube Cool Tube (150L)

A cool tube is effectively a heat resistant glass tube containing a lamp holder and reflector panel. Air is then blown down the cool shade tube by an extractor fan connected by ducting. The air passing through the tube directly cools the lamp and removes hot air. The glass of the cool tube will only get warm not hot due to the air passing through it. 

This type of reflector is a very cost effective way of helping to reduce temperatures in your grow space. This is especially important during hot summer month when plants can suffer with hot temperatures. There is also the added bonus of being able to position the reflector closer to your plants as this type of reflector will not get hot.
