SKU: Kit D-SLS-K4

LED retrofit kit

The D-SLS-K4 kit renews the technical core of existing lanterns and decorative luminaires while keeping their housing: a plate with 1 to 4 reflector LED modules, 20 to 120 W, with an adapter ring for diameters from 500 to 800 mm. The most economical way to switch to LED (up to 22,440 lm, 187 lm/W) without changing the look of heritage lighting.

Key features

Heritage preserved

The Ø 500 to 800 mm shell stays in place: only the technical core is new, the look is unchanged.

1 to 4 modules

Modular board 20 to 120 W to suit photometric needs — white-lacquered circular reflector.

“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.
