The Cooltube reflectors have been developed to dissipate the hot air produced by the high pressure lamps more efficiently. This is achieved by blowing colder air through the reflector or extracting the warm air from the reflector. Which way one chooses depends on the setup and personal preference. As long as the right conditions are adhered to, both ways are more efficient to remove warm air than an average reflector. One of the conditions is that the maximum number of reflectors that can be connected to each other, as well as the minimum and maximum distance to the plants, are adhered to. This is the only way to enjoy the Cooltubes in the end. A big advantage of the Cooltube reflector is that the reflector can be hung lower, allowing the plants to receive more light without burning through the heat.
