Key features
Replaceable ogival bowl
UV-stabilised polycarbonate or blown glass, clear or opal — the wear part is replaced on its own.
“Dark-light” indirect reflector
Indirect (inter-reflection) aluminium reflector ρ≥ 98 % (ISO 7668 / DIN 5036-3): the LED is never seen directly — optical efficiency ≥ 95 %, glare-free, no PMMA lens.
LUSSO-5050AUX LED module
Source 280 lm/W, luminaire 187 lm/W (4000 K · CRI 70 · Tq 25 °C), L90B10 ≥ 100 000 h (TM-21) — module replaceable on site.
NFC-programmable driver
DALI-2 and D4i + DT8: wirelessly adjustable output current, dim-to-off < 0.5 W, stand-alone dimming profiles, OLC compensation.
Remote management ready
Zhaga Book 18 socket: the LiDAR-ATMANI-AI node and the LidarMesh CMS platform can be added at any time, without opening the luminaire.
Full protection
Type II SPD 10 kV / 10 kA with end-of-life indicator, IP66, IK08, stainless steel pressure-equalising valve.
7-year warranty
Extension to 10 years (W10 option) — electronics from ENEC-certified series, product-specific EU declaration of conformity.
