The Cool Tube is a tubular armature of glass with the function to regulate the temperature of the lamp. Warm air that is given off by the lamp is sucked out, resulting in less heat in the growing space. The socket in the Cool tube is a E40 model. Connects to 125 mm fan or tube. 49 cm long.
Attach a fan and it will blow the hot air from the lamp away. The temperature rise of the lamp will thus be reduced by 30-40%. The lamp can also be brought nearer the tips of the plants. Ideal for rooms where chains of lamps are needed.
