DEXAM SAVED £12,000 PER YEAR BY INTEGRATING HYTRONIK SAM7 SENSORS IN ITS WAREHOUSES.

A plug-and-play upgrade that dramatically improved visibility and reliability, complied with the fluorescent ban, and delivered ROI in just 1.7 years.

Dexam, a leading UK cookware supplier, faced the imminent ban on fluorescent tubes in September 2023 and sought to cut ongoing maintenance costs. Low Energy Designs replaced 125 fluorescent tubes with 112 LumiROD 414 and 416 LED luminaires, each equipped with our Hytronik SAM7 HF Low-bay sensor. Fewer fittings delivered greater light output, while intelligent control made this project truly outstanding.

THE CHALLENGE

• Achieve optimal lighting levels: Existing fluorescent tubes failed to meet the lux requirements for safe operations.

• Minimise operational disruptions: Frequent tube failures and maintenance shut-downs were costly and time-consuming.

• Ensure regulatory compliance: All fluorescent tubes needed replacing with LumiROD 414/416 fittings featuring Hytronik control before the September 2023 ban.

• Implement smart occupancy control: Prevent low-activity areas remaining lit unnecessarily.

• Secure rapid ROI: Obtain payback within two years without major building works or extra infrastructure.

THE SOLUTION

On-Demand, Precise Lighting

By integrating a SAM7 sensor into every LumiROD, Dexam shifted from constant 24/7 illumination to a presence-activated system that switches on when staff enter an area and dims or turns off when it’s vacated—eliminating wasted energy.

Daylight Harvesting

Thanks to the SAM7’s daylight-harvesting feature, each luminaire automatically adjusts to maintain 800–1,200 lux based on natural light levels, with no manual intervention.

Fewer Failure Points

Reducing from 125 tubes to 112 LumiROD units minimised wiring and maintenance points, concentrating light output in more reliable equipment.

Instant, Plug-and-Play

Commissioning RJ12 connectors and IR remote control enabled threshold and scene settings to be configured in minutes—no expensive programming or lengthy installation required.

Wireless Scalability

With no central controllers needed, each fitting operates independently, making it simple to add or relocate units without extra cabling or network reconfiguration.

THE RESULTS

• 60% increase in lighting levels, ensuring perfect visibility.

• £12,000 saved per year on energy and maintenance costs.

• ROI in 1.7 years, demonstrating rapid investment recovery.

• 5-year warranty, guaranteeing peace of mind and minimal upkeep.

• 57.3% annual CO₂ reduction, lowering environmental impact.

• Regulatory compliance achieved well before the fluorescent ban deadline.
