The original Cooltube is an air-tight, fully sealed clear glass tube with a lamp mounting bracket in its centre. It's perfect for removing the excess heat generated by HID grow lights without leaking unpleasant odours.

Air is usually pulled (but can be pushed) over the lamp by adding an extractor fan to one side of the tube, the hot vented air is then expelled away from the growroom and plants. They're very effective, somewhere in the region of 70-80% of heat is removed, but due to the shape of the reflector the spread of light they give off is not the best. The Goldstar is also fully sealed and gives a much better spread of light, but is quite a bit more expensive.

Reflector Measurements (approx):

Length:  40cm
Width:   15cm
