“Dark-light” indirect reflector
Indirect (inter-reflection) aluminium reflector ρ≥ 98 % (ISO 7668 / DIN 5036-3, EN 10204 3.1 material certificate), recessed source not visible beyond 70°: optical efficiency ≥ 95 %, ULOR 0 %, class G*6, TI ≤ 10 %.
D-SLS-14 LOTUS
LOTUS — Street lighting
Street platform 20–250 W
LOTUS D-SLS-14 is D-SLS's flagship LED street light: three sizes (LOTUS 3, 2 and 1) cover 20 to 250 W with the same optic, the same driver and the same remote-management socket. Its indirect 'dark-light' reflector (≥ 98 % reflectance) lights the road without glare and with no upward light (ULOR 0 %). Fully serviceable on site and ENEC certified, it replaces a 250 W high-pressure sodium lamp with an 80 W LED.

Key features
Tool-free maintenance
Hook-opening cover in die-cast aluminium, removable gear tray, plug-in driver and LED module: all work is done from the aerial platform, without removal.
Zhaga Book 18 LED module
Removable, on-site replaceable module, under-driven LUSSO-5050AUX LEDs — 280 lm/W at source, ≥ 100 000 h L90B10 (TM-21).
NFC-programmable driver
Zhaga-certified DALI-2 and D4i: wireless adjustable output current (AOC), dim-to-off < 0.5 W, 3 timer modes, OLC compensation, 24 V DC auxiliary.
Remote management ready
Zhaga Book 18 · 20 socket fitted as standard: the LiDAR node and the LidarMesh CMS platform are added later, without opening or removing the luminaire.
Full protection
Type II SPD 10 kV / 10 kA with end-of-life indicator, IP67, IK09 overall, class II or I, IP68 stainless cable gland.
Three sizes, one platform
LOTUS 3 (20 – 50 W), LOTUS 2 (60 – 110 W) and LOTUS 1 (120 – 250 W) share optics, driver, Zhaga base and accessories — a single spare-parts stock for the entire fleet.
7-year warranty · ENEC certified
Extension to 10 years (W10 option). ENEC certificate HN 69290740 (TÜV Rheinland) and TÜV SÜD attestation — repairable luminaire, ecodesign compliant.
