Zest SAD & wake-up light photo

Working as both a SAD light and wake-up light, Zest mimics a sunrise to wake you gently in the morning, while providing bright light therapy throughout the day.

Compact two-in-one device.
Its blue-enriched white LEDs gradually brighten to fully wake you in the morning, while its five light levels provide bright light therapy during the day to lift mood, boost concentration, restore natural energy and treat the symptoms of Seasonal Affective Disorder (SAD).

15–30 minsunrise duration

Get the best of both worlds with Zest! The two-in-one device is a handy size for home, work or travel, making it ideal for use as part of a jet lag plan.
