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

All of our grow light systems are supplied with Sunmaster Dual Spectrum lamps and your choice of three ballasts, please make your selction from the dropdown above:

Compact Ballasts (analog) - These have been our go to ballasts for over 10 years, and are still one of the most reliable ballasts on the market, they just work really well and come with a 5 year guarantee on the 600W version, 3 years on the other 250W, 400W and 1000W versions.

Sunmaster FX 600w Dimmable Ballast. Dimmable to 250W, 400W and boostable to 660W, the Sunmaster FX is a great digital ballast at a good price.

Maxibright Promax 600W/400v. If you want the best money can buy then choose this ballast. It uses 400 volt technology and will give you about 5-10% more plant usable light, as well as a whole host of other features. It can also run standard 240v lamps, it's the most advanced ballast on the market at the moment.
