Working at Night, Internal Clock is Off Track

We bought this Happy Light for my son. He works at night and his internal clock was getting messed up. We hoped it would help and it has! He takes about 15-20 minutes daily to sit in front of it and he says it is making a huge difference. He has more energy and is in a better mood and while he still works nights he is able to get good sleep. Each person who uses it will find their own results but this light has done its job for my family.

Severe SAD

I have suffered from severe seasonal affective disorder for years and this light makes an unbelievable difference! Every time I turn it on it feels like I have spent the day in the sunlight. I usually use it for 30-40 minutes each day and wow! I can feel the improvement it is making. I can honestly highly recommend this light to anyone who may even slightly suffer from seasonal or non-seasonal depression. Its really unbelievable the difference a little extra light can do for you. Thank you Verilux!!!!

It is hard to convince me to believe something

It is usually difficult to convince me to believe something, but I must say, I bought a happy light and it is absolutely awesome! I get up at 4:00 in the morning to get ready for work and usually begin feeling depressed pretty quickly. I got this light and began putting it in the place I would be most in the morning while getting ready. It just drew me in light a moth and I wanted to be near it. Funny, my cats are normally right by my feet in the morning but now I find them relaxing in front of the light. I really feel so much happier and full of energy now through the day. It is seriously a miracle for me. Can’t recommend these Happy Lights enough!

The Verilux HappyLight® Liberty Mid-Size Light Therapy Lamp works in 3 easy steps:


Find a suitable, convenient place for your HappyLight®, such as a table top or desk, and turn the lamp on.


Set the HappyLight at an angle and distance you find comfortable. Be sure the light box is facing your eyes but try not to look directly into it).


We suggest beginning with a 10 minute session, then increasing usage up to between 30 minutes and 1 hour daily until you identify an interval that is ideal and most effective for you.
