Product number: LK142
Available stock: 1

The LK142 Staircase Effect Controller allows the control of staircase lighting from 8 - 32 steps. It offers a total of 32 outputs, e.g. for LED strips or profiles in the range of 5-24VDC, 1A. For example, our standard LED strips as well as the new free-cut COB LED strips can be controlled flexibly. 

Controlled by pushbuttons or motion detectors above and below the stairs, the steps can be illuminated step by step with great effect. Depending on the activation, the effect runs from bottom to top or from top to bottom. 

In addition, digital pixel LEDs can be integrated for a running light, e.g. in the handrail. Various effect modes and speed settings allow for flexible adjustment of the staircase effect.

Benefits at a glance: 

  • Selective control of 8-32 steps with 5-24VDC, 1A 
  • Additional chaser effect, e.g. in the handrail, via pixel LED strips (12 color modes) 
  • 4 effect modes, 8 speeds 
  • Triggered by PIR motion sensors or push-buttons above and below the stairs 
  • Daylight sensor for twilight switching 
  • 2 controllers can be cascaded for large staircases with up to 64 steps
