SUCCESS STORY: 336 LUMINAIRES WITH BUILT-IN CONTROL – FULLY AUTONOMOUS LIGHTING FOR A SWEDISH FACTORY

A pioneering installation in Sweden that changed the way lighting control is sold.

Three years ago, when talking about Bluetooth sensors still felt like science fiction in the Swedish industrial market, Exaktor decided to take the leap. They started adding control to their lighting projects using Hytronik sensors and the Koolmesh app.

The project: a large-scale factory with over 330 luminaires, where the challenge wasn’t just about saving energy – it was about doing so without compromising functionality or operational safety.

What seemed like just another technical installation quickly became a commercial tool. Because thanks to the data generated by Koolmesh – and the expertise of the Exaktor team – this project didn’t just satisfy the client: it brought many more on board.

A wireless network. Flexible programming. And a system that, thanks to its architecture, costs the same as a traditional solution… but offers so much more.

THE CHALLENGE

• Reducing energy consumption without compromising lighting quality: The client needed a solution that would significantly lower energy usage while maintaining lighting standards.

• Adaptable control across multiple zones: The system had to cater to different areas with specific lighting needs, including forklift traffic routes.

• Autonomous, reliable, and programmable: Each luminaire had to operate independently and adapt in real time to presence and daylight conditions.

• A robust and adaptable logic system for demanding industrial environments.

• Live data and a powerful sales argument: The solution needed to provide real data – not just for system monitoring, but as a compelling sales tool for future clients.

• Scalability: The system had to support future expansions without compromising the existing setup.

THE SOLUTION

1. 336 Tage DALI industrial luminaires from Exaktor (IP23, 15.000 lumens), equipped with Hytronik HCD049BT sensors

• The HCD049BT sensors feature Bluetooth connectivity, DALI power supply and IP65 protection.

• Direct integration via side-entry batten-mount.

• Ideal performance for mounting heights between 3 and 15 metres.

2. Smart zoning with autonomous and stairwell functions

• Most luminaires were programmed as standalone units with daylight compensation.

• In logistics aisles, the stairwell function was activated to pre-light adjacent luminaires, ensuring visibility for vehicle movement.

3. Koolmesh + Gateway for monitoring and future scalability

• Koolmesh enabled flexible programming, scene control, scheduling and consumption monitoring – all from a mobile app.

• The addition of a gateway allowed real-time data capture, report generation and lighting behaviour monitoring by zone.

"2 + 2 = 4, but 3 + 1 is also 4. In a traditional installation, luminaires and sensors cost 2, and installation costs another 2. With Koolmesh, control is built directly into the luminaire – so installation becomes simpler. Same result. Less hassle. And endless flexibility. " Anders Schultz.

RESULTS

• Energy savings without compromising visibility: Lighting responds automatically to presence and daylight, optimising each luminaire's operation.

• Safe, logical and customised zone control The stairwell function improved safety in circulation areas by pre-lighting key paths – no more forklifts navigating in the dark.

• Real data that wins over clients: Thanks to the gateway, Exaktor accessed clear, actionable energy data that validated performance claims. These reports became key in attracting new customers and helping them meet compliance standards.

• Scalable, flexible and economically smart: This project proved you don’t need a complex setup or inflated budgets to implement a smart, future-ready lighting system. Koolmesh offers growth, reconfiguration and maintenance – without building work or disruption.
