Select the Weather

Select the Weather

For out-of-the-box Human Centric Lighting

With Select the Weather (StW) it is possible to simulate different scenes of the natural outdoor lighting environment by changing the colour temperature and intensity of the lighting.




Select the Weather is built to support the end-users' freedom to choose their desired lighting from a wall panel. With Helvar's new DALI colour control,  it is possible to simulate range of natural outdoor lighting scenes by changing the colour temperature and intensity of the indoor lighting.

Helvar's solution is easy and quick to install without any on site configuration, due to the intelligence embedded in the drivers. You only need to connect a panel, a DALI power supply, and iC Dynamic drivers in the luminaires to get it working.

For a fully functioning solution, you need only

  • Helvar Select the Weather panel
  • Helvar Dynamic LED Drivers in the luminaires
  • Helvar iDim Solo DALI power
  • Helvar Ceiling Motion Detector (optional)
