Our Modes

Each BioSync bulb has three precisely tuned light modes that guide your body through the natural rhythm of day and night — helping you stay energized when you should, and relaxed when it’s time to unwind.
Switch modes easily with a simple toggle of your wall switch.

Firelight Mode

End your day with a deep amber glow completely free from blue light — your body’s cue for rest.


It recreates the soothing warmth of firelight or candlelight, allowing your nervous system to relax while preparing your body for deep, restorative sleep.


Perfect for reading, meditating, or creating a peaceful nighttime atmosphere.

Relaxing • Restful • Sleep-Promoting

Sunset Mode

As the day winds down, switch to a gentle amber tone that transitions your body from daytime activity to evening calm.


This mode softly reduces blue and green wavelengths — helping your brain recognize that night is approaching and encouraging melatonin production naturally.


Ideal for dinner, relaxation, or screen-free wind-down time.

Warm • Gentle • Restorative

Daylight Mode

Start your day with bright, full-spectrum light that replicates the clarity and balance of natural sunlight.


This mode boosts alertness, enhances mood, and helps you feel more awake and productive — without the harsh glare or flicker of standard LEDs.


Perfect for work, morning routines, or any time you need focus and motivation.

Energizing • Clear • Focus-Enhancing
