Get Back to Being You™

The HappyLight Just for You!

Five years in the making, the HappyLight Liberty incorporates the most power and flexibility available in an energy lamp – in a discreet, compact size you can use at home or away – the office, dorm, or even the gym.

Beat the Winter Blues & the Effects of Seasonal Change

The Verilux Liberty Energy Lamp provides up to 10,000 LUX of full spectrum light (scotopic light measured at 10 inches), the highest recommended output for addressing seasonal change, the "Winter Blues" (a subclinical form of Seasonal Affective Disorder [SAD]) or the effects of shift work, jet lag, malaise or fatigue.

Improve Mood, Energy, Focus & Productivity

Balanced Natural Spectrum Daylight taps the potency of light to gently cue your body to recalibrate and stabilize, naturally reducing fatigue and lethargy while improving focus.

Customize a Program that Fits Your Goals, Body & Lifestyle

No two people view and react to light in the same way, so this energy lamp provides the flexibility to customize the light to meet your needs. High-Low intensity controls, interchangeable lenses and a tilt feature give you the maximum flexibility to design the program that works best for you.

A broad field of up to 10,000 LUX* of light provides a more flexible program, allowing you to be farther from the lamp and to move around more freely during use.
