With our partner Granitor, we modernised the Kv. MARS parking garage with a new generation of SROW LED luminaires. The previous LEDs had failed after just five years; the new system delivers high-quality light with full DALI-2 control.

THE CHALLENGE

The Challenge: Replacing Failing LEDs Without Sacrificing Output

The Kv. MARS garage was originally fitted with LED luminaires that began deteriorating after only five years of service — far short of expected LED lifespans. Granitor needed a replacement that would address three constraints simultaneously:

  • Maintain the existing target illumination of ~300 lux across the garage floor
  • Achieve a measurable energy reduction (~10%) on top of the like-for-like swap
  • Accommodate different optical requirements across aisles, parking bays, and connector zones using a single shared platform for simplified maintenance
THE SOLUTION

The Solution: SROW Linear Fixtures with Location-Specific Optics

We deployed Triton SROW Gen. 3 linear LEDs in two lengths (1.2 m and 1.7 m) sharing one base configuration but with location-specific optics. Combined with DALI-2 dimming, the system holds the target 300 lux and cuts connected load ~10%.

  • Unified Base Configuration: All fixtures share the same SROW Gen. 3 platform — 5000K CCT, Ra80 colour rendering, DALI-2 driver, IP53 cable-gland termination — keeping spares simple and installation predictable.
  • Location-Optimised Optics: 90° beam for main aisles and 145° wide-beam for parking bays and connector zones, selected per installation point to maximize uniformity at the target 300 lux.
  • 193 lm/W System Efficacy: SROW S17 (1.7 m, 33–99 W power-adjustable) and SROW S12 (1.2 m, 66 W) both deliver up to 193 lm/W — at the top of their class and the key enabler of the 10% energy reduction.
  • Full DALI-2 Smart Control: Dimming groups and scenes configured via DALI-2 bus enable fine-tuning per zone and leave the door open for occupancy-based control without rewiring.
  • Circular Design: ~80% of components are field-replaceable and 100% of the chassis is designed for reuse, dramatically reducing the lifetime environmental footprint compared to disposable LED fixtures.
PRODUCTS USED

Products Used

  • Triton SROW S17 Gen. 3: 1.7 m length, 33–99 W power-adjustable, 5000K, Ra80, 90°/145° optics, DALI-2 — main aisle and large-zone fixture.
  • Triton SROW S12 Gen. 3: 1.2 m length, 66 W, 5000K, Ra80, 90°/145° optics, DALI-2 — used in tighter parking bays and connector zones.

Vossloh-Schwabe Components::

  • DALI-2/B2L Driver 90W (187338)
  • DALI-2/B2L Driver 120W (187031)
  • Cable Gland connector — IP53 termination
RESULTS

Lighting holds the targeted ~300 lux across the entire garage while connected load drops ~10%. DALI-2 control lets the operator dim off-peak and add occupancy sensors later without rewiring. SROW's 80% replaceable parts keep it future-proof.
