Cool Tube 150 mm. Double & Stuko Reflector

150 mm diameter Cooltube with reflector, 890 mm long, with lampholders at both ends. Tubular reflector made of special high-temperature resistant glass. Its use in combination with an extractor prevents heat emitted by discharge lamps from spreading into the greenhouse. It also allows the light to be closer to the plants as it does not emit as much heat.
