Along with its emotional aspects, KOI also sets new standards in office lighting with its use of efficient lighting technology. This is due to modern lighting technology and the light head. The four powerful 42W fluorescent lamps with a total output of 13 000 lumens are so positioned to ensure 20% less light loss compared to conventional office standing lights. KOI reflects up to 70% of light from the ceiling resulting in abundant and fatigue-free lighting. The remaining 30% is directed glare-free onto work surfaces using pyramidal lenses. The rounded form ensures rotational symmetry and equal light distribution over a wide area. Despite the high output, KOI is certified to Minergie standards.
