WTV EMDR Light Bar Set – App-Controlled Visual Bilateral Stimulation
The WTV EMDR Light Bar is a visual bilateral stimulation device for EMDR therapy, controlled wirelessly from the free EmA mobile app over Bluetooth. There are no knobs or control units: your phone becomes the control panel.
Light Bar + Mobile App – That’s All You Need
The WTV set is simple: the LED light bar and the EmA app on your phone. Pair them once, set the stimulation, start the set and follow Sets, Beats and set time on screen. EmA keeps a session log and reconnects automatically if the Bluetooth connection drops.
Customizable Visual Stimulation for Effective EMDR Therapy
✅ 6 light colours
✅ Sweep or Blink animation
✅ Adjustable brightness
✅ 30 speed levels, fine-tuned while a set is running
✅ Auditory BLS through headphones connected to the phone, synchronised with the light bar
