## What is Sol?

Sol Spektrum is the companion app for the Sol Spektrum photonic stimulation device by GridLights — a portable, hexagonal light with 37 high-output LEDs that flicker at precise frequencies up to 50 Hz.

Pair the app with your device over Wi-Fi or Bluetooth, then shape the light:

• Journeys — guided light programs that move through frequencies over time, organized by intent: Waking Dreams, Focus, Relax, Sleep, Creativity, and High Cognition.

• Sequencer — build your own ordered sequences of scenes, each with its own color, brightness, speed, and duration.

• Live control — adjust frequency, brightness, and color in real time, with an on-screen preview of the device as it plays.

• Device & updates — manage your Sol Spektrum and install firmware updates over the air.

Sol Spektrum requires the Sol Spektrum hardware device to use.

Photosensitivity warning: this device produces flickering and strobing light. Do not use it if you have photosensitive epilepsy or a history of seizures, and consult a medical professional if you are unsure.
