Lumenate experiences are designed to take you into a deeply meditative state, so creating an environment that can foster this state this is very important. The key factors for a great environment for Lumenate experiences are:
A dark space - Lumenate uses the torch on your phone, strobing at specifically designed frequencies onto your closed eyes. Doing Lumenate in a bright space would dilute the light from your phone's torch and lead to a weak experiences. For the most immersive experiences, find or create an environment that is as dark as possible.
A quiet space, away from distractions - Distractions can very easily take you out of deep states of meditation. If possible, find an environment that is quiet and away from people or things that could interrupt your experience.
