CRAFT II.

CRAFT II Family

• Replication of a natural phenomenon – TIR (Total Internal Reflection)
• Transparent, laser-structured lenses with a micro-metrically 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

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

CRAFT II performance

The robust lightweight

• Sustainably produced
• Powerful in action
• Lightweight yet sturdy sheet steel housing
• Highly efficient high-bay luminaire
• Extremely versatile thanks to six different light distribution curves
• Housing “Made in Germany”, in a zero carbon production process

CRAFT II plus
The unbeatable power pack

• Protective shield made from a single mould
• Created while using the aluminium die-casting process
• Distinguished by its impressive resilience
• Revolutionary thermal management
• Made for challenging ambient temperatures and extreme mechanical or chemical stresses

CRAFT II: Revolutionary thermal management

Self-cleaning thanks to the Coanda effect, which 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.

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 Venturi effect cools the CRAFT II plus luminaire very efficiently and allows the powerhouse to be operated even at extremely high ambient temperatures.
