CRAFT II
Revolutionary thermal management
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 powerhouse to be operated even at extremely high ambient temperatures.

Self-cleaning thanks to
the Coanda effect.
the Coanda effect.
The Coanda 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.

Light quality from ZUMTOBEL
- Replication of a natural phenomenon – TIR (Total Internal Reflection)
- Transparent, laser-structured lenses with a micrometrically small, diagonal dome-like structure
- Reflection of the whole ray of light like a mirror
- Distribution of the light rays optimally in the room – precise and highly efficient
- High lumen output:
CRAFT II performance size M: 21.000 lm
CRAFT II plus size M: 25.000 lm - Unbeatable combination of lumen output and efficiency
- Up to 195 lm/W
CRAFT II
Controlled Glare Optic
The CRAFT II product family also offers a very elegant solution to a common problem in all high-bay luminaires:
- their glare or perceived glare. This occurs for example in a logistics setting or in sport – especially in any situations in which people look up and directly into the light from a high-bay luminaire
- Zumtobel has developed an innovative “controlled glare optic”
- An integrated louvre enhances the appearance
- Creates two additional light distribution options: “narrow beam controlled glare” and “wide beam controlled glare”
- Extremely effective in reducing glare to a minimum and enable a UGR < 19
