Light Control

Lighting runs – even when nobody needs it.

In many companies, the greatest savings potential lies not in the lamp – but in the control system.

/ The Problem

What happens in most buildings

Lights are on even though nobody is in the room

Halls run at 100% – regardless of usage

Controls are only used as on/off switches

The result: Energy consumption without benefit.

/ Savings Potential

The biggest savings potential is being overlooked.

Many systems could operate far more efficiently – without replacing the lamps. Intelligent control creates savings that pure modernization often cannot achieve.

80%

energy savings possible through intelligent control.

/ Control

Control determines efficiency.

It's not the lamp that determines consumption – but how it is used. We develop control systems oriented to actual usage:

01

Demand-driven

Light only where it is needed.

02

Daylight-adaptive

Automatic adjustment to natural light.

03

Zone-based

Individual control instead of full-area lighting.

/ Sensors

Without sensors, control stays blind.

Only through sensors does lighting become truly intelligent. The result is a system that reacts automatically – instead of being manually controlled.

What sensors detect:

Presence
Daylight
Usage patterns

/ Reality

The technology is often already there.

Many buildings already have control systems in place.

They are not being used.

Or only minimally.

The real potential remains untapped.

/ Technology

Technology is not the problem.

DALI, KNX, ZigBee, Bluetooth Mesh or Matter – all systems can work.

What matters is not the technology – but how it is deployed.

/ Example

Warehouse: Before vs. After.

Without control

  • Lights run continuously
  • Large areas are rarely used
  • 100% power regardless of demand

With control

  • Light only in active zones
  • Automatic adjustment to usage
  • Significantly lower energy consumption

/ Result

More efficiency – without new lighting.

  • Up to 80% energy savings
  • Longer component lifespan
  • Lower operating costs

Without replacing lamps. Only through intelligent control.
