HIGHBAY AND HIGH PROTECTION LUMINAIRES
CRAFT II
Revolutionary thermal management. The CRAFT II plus uses two fundamental principles of physics, the Venturi effect and the Coandă effect, to cool and clean itself. The result: the innovative high-bay luminaire is in a completely different class from its predecessor model and can withstand high ambient temperatures (up to 70°C) – throughout its entire lifetime of around 100 000 hours. To achieve this, CRAFT II plus relies on an intelligent interplay of air pressure, air speed and air temperature. And all in an aluminium housing with excellent thermal conductivity.

Efficiently cooled thanks to the Venturi effect. Specially designed nozzles in the body of CRAFT II plus generate negative pressure – and thus ensure that the air circulates at a high speed between the LED drivers and LED boards. The so-called Venturi effect cools the CRAFT II plus luminaire very efficiently and allows the power pack to be operated even at extremely high ambient temperatures.
Self-cleaning thanks to the Coandă effect. The Coandă effect is a principle of physics used in the aviation industry and applied to CRAFT II plus: a pressure imbalance presses the airflow against the curved surface of the luminaire. This efficiently cools the LED boards in particular. At the same time, the airflow also removes everyday dust from the surface of the luminaire.
