Designed for the treatment of Seasonal Affective Disorder (SAD), this lamp will bring a little light into everyone’s life. The blue spectrum (cold cathode florescent tube) simulates the therapeutic effects of natural daylight wavelengths. Perfect for when the days get shorter and the nights get darker.

Remarkably, this light therapy is also helpful to combat the effects of jet lag as well as improving physical and mental wellbeing during dark, short winter days. A slider switch adjusts the light power from low to full brightness. The light colour temperature is rated at 6,300K and the brightness is 10,000 lux at 2 inches or 2,500 lux at 6 inches on full power.
