Great program diversity
ALPHABET ZONO family offers high-output LED downlights both round and square designed to set new standards in the downlight segment.
High system efficiencies result in energy savings and short pay-back periods. Thanks to the highly efficient light chamber and the light-proof housing light is only directed where it is needed.
Thanks to numerous VERSIONS and SPECIAL DESIGNS, such as insect-proof designs or those with 49 mm recessed depth, this product line copes with just about any building challenge.
Perfect all-round Glare Control
With UGR < 19, a shielding angle of α > 30° and γ 65° < 1000 cd/m² these downlights comply with the highest grade of glare control in accordance with EN12464-1 and are therefore suitable for all VDU applications. This is ideal if the display screen quality can only be defined at a later stage.
Homogeneous light
Integrated diffusing disc with microbead technology
Visible light
CORONA OPTIC
PMMA with multiple surface prisms for EXACT GLARE LIMITATION in combination with DISCREET CEILING ILLUMINATION. Integrated in a highly specular reflector for tool-free use in the luminaire module, safety suspension included.
DECORATIVE LIGHT OPTICS make the light pleasantly visible. Depending on the version, the light is scattered softly into the room or onto the ceiling. Architecturally, they set accents.
By using a protective pane or diffuser, the protection class of the luminaire can be upgraded to IP44 from below in closed ceiling systems.

INSECT-PROOF DESIGNS
CLEAN OPTICS for Connecting Passages and Canopies
PROTECTION CLASS IP54 and INSECT-PROOF - Because of the reflector space is encapsulated and the housing is lightproof, there are no insects on the lower cover screen. This guarantees a CONSTANT LIGHT DISTRIBUTION, REDUCES MAINTENANCE and provides a CLEAR CEILING APPEARANCE.

PROBLEM SOLVER
with as little as 49 mm RECESSED DEPTH
Air conditioning ducts or sprinkler systems very often limit the recess depth in suspended ceiling systems. The special designs in the ALPHABET ZONO range with only 49 mm RECESSED DEPTH, are the ideal problem solver.
Different performance levels are available in round or square shape, incl. PMMA cover with microbead technology.
