Recessed downlight JILLY QUADRATISCH

recessed ceilingLEDsquare

Product description
Jilly recessed luminaires provide an efficient solution for norm‑compliant office workplace lighting. The concise design with a prominent anti‑glare louvre distinguishes Jilly from conventional office luminaires. The lighting system combines a highly efficient lens with an anti‑glare louvre to deliver high visual comfort and luminous efficacy.

Key features of Jilly square

• Suitable for office workstations: Designed for good glare control and high visual comfort; UGR values serve as orientation but must be applied with regard to the specific luminaire arrangement.
• Anti‑glare louvres: Limit the view into the luminaire and provide visual comfort with an emission angle of approx. 90°. Available in black or silver to match ceiling materials and colours.
• Shallow recess depth: Developed for compact mounting situations where installation depth is limited.

Applications
Jilly square is used for general lighting in office and communal interiors. Product imagery typically illustrates office and educational interiors.
