As you may know, we often don't get enough sunlight or even daylight for that matter. Our hectic work and home lifestyles tend to keep us indoors and away from an essential element we can't live without - sunshine. A dose of full or natural spectrum light is a welcomed lift to mood, increased energy, improved sleep patterns, and enhanced health, happiness & well-being.


Our HappyLight Full-Size 10K Light Therapy Lamp is a tried-and-true product and a customer favorite. With a 4.6/5 star rating and almost 1,000 reviews, this product it dependable, reliable and will quickly become something you look forward to every day. We put our Verilux Guarantee to work for you, so if you find this light therapy lamp is not the one for you, we will take it back within 30 days and give you a full refund.

The Verilux HappyLight® Liberty Full Size Light Therapy Lamp features:

  • This full size model offers natural and safe full spectrum light therapy and is practical for easy use each day.
  • Ideal for late work shifts, office desk lighting, jetlag, sunlight deficiency and insomnia.
  • Improves energy, focus and mood and helps to reset your sleep cycle, or circadian rhythm.
  • Recommended by professionals, providing UV-free bright white light therapy and 10,000 lux.
  • Light surface area is broad and produces more light per sq. inch for the most efficient sessions.
  • Adjustable intensity controls, High to Low, to customize to your preferred level.
  • Includes 2 interchangeable lenses: High-Energy and Comfort Optix® Glare-Control Lenses that lessen eye fatigue and strain.
  • Comes with a 36 watt full spectrum light bulb that is cool-burning and energy efficient.
  • Turns on instantly and features no-buzz operation due to electronic ballast and Flicker Elimination Technology™.

This 10,000 lux light therapy lamp offers a UV-free supplement to natural sunlight and contributes to a healthy lifestyle. It features a simple high/low switch, so you can adjust it to the intensity level you feel is right for you. It can also be tilted up or down to adjust the angle of the light and to make sure it's comfortable on your eyes. And if that's not enough, it can be hung on the wall as well for added flexibility.

Because the intensity of this light therapy lamp is high, the amount of time you sit in front of it can generally be on the shorter side. You will get your daily dose of light quickly. However, we always recommend starting with 10 minutes and working up from there to find your ideal timeframe which is likely to be around 30 minutes, give or take.

But don't worry that you need to find another 30 minutes in your day because one of the great things about your HappyLight routine is that it can fit right into your existing schedule. Sit it at work next to your computer monitor, place it on your counter at home while you eat breakfast, have it next to you while you read the news or practice yoga, or keep it in the bathroom while you get ready for your day.

The Verilux HappyLight® Liberty Light Therapy Lamp works in 3 simple steps:


Set your HappyLight® in a suitable place, such as on a table top or your desk and turn it on.


Identify a comfortable distance and angle to your face (be sure the HappyLight is directed toward your eyes but try to avoid looking directly into the light)


Verilux recommends beginning with a 10 minute session and increasing from there to between 30 minutes and 1 hour until you find a timing that is ideal and most effective for your needs.

Small and mighty lamp

I love the size, and ease of use! I set it near me in my bedroom, living room, or at my desk, depending on the morning! There aren't a ton of buttons to mess with, which is great. The best part is that it provides a great light session! I highly recommend this device. The light timer is 15 minute increments, not 5 minutes as advertised, but that doesn't matter much.

Gift that Gives

My dear long time friend suffers from SAD. Last year I purchased the Happy Light for my daughter who lives in Idaho and she found it helped tremendously. I knew my friend had to have one, too. So for her birthday, I gifted her the light, and even though its still summer, she has used it several times already with excellent results !!!! LOVE it!!!

Happy Light Luxe VT43WW3

Our older larger Verilux Light after many years of service, decided to quit on us. There was no question as to what brand we would purchase, just what model. This one has three levels of light and a timer. It has a much slimmer design with a sturdy base which was a plus. We expect many years of a happy experience with our light. Also, the customer service is amazing and is local (Vermont).
