Wide Spread 6″ Cool Tube
The Coolshade Reflector.
The Coolshade 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; as far as we know it's the only fully sealed system on the market (other manufacturers claims that theirs are but in our experience they are definitely not).
