Cooltube 150mm Grow Light
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.

The Cooltube 150mm Grow Light is available with 5 different types of ballast, please make your selection from the dropdown above. You can click the links below for more info on each ballast:
Parbright Ballasts (600W analog): Parbright ballasts are plastic cased and silent running and are a quality entry level ballast option.
Maxibright Compact (magnetic): Maxi Compact ballasts are superior to all other resin cased ballasts that we have come across. Wall mounting is advisable. Available with this kit in 250W, 400W and 600W (Pro).
Maxibright Digilight: If you prefer a digital ballast that is not dimmable (i.e. less things to wrong) then the Digilight is a good option, the 250W version is especially good value for money.
Varidrive: Dimmable to 250W, 400W and boostable to 660W, the Varidrive is a good digital ballast at a great price.
Warranty: 1 year. (this is the new version of the the Digidrive ballast).
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.
