PERFECT FOR: • Meditation: Use the red glow as a focal point to center your thoughts. • Nightly Routines: Replace harsh room lighting with SUNI while you prepare for bed. • Yoga & Stretching: Create a studio-like atmosphere anywhere you go. • Focus & Flow: Use the steady red light to reduce visual clutter and focus on the task at hand.
