Liberty 10,000 Review

So How Does It Work?

The novel factor about the HappyLight Liberty 10,000 is that not only does it have two intensity settings, it also has two easily interchangeable lenses that each provide a different light range and energy. This means you get four light intensity options to suit your needs.

This Verilux comes with a Comfort Lens (this is the lens that is installed) and a High-Energy Lens. Basically the combinations of lens and intensity work as follows:

  • Comfort Lens – Low Intensity Setting = 3,500lux
  • Comfort Lens – High Intensity Setting = 5,000lux
  • High Energy Lens – Low Intensity Setting = 7,500lux
  • High Energy Lens – High Intensity Setting = 10,000lux

So as you can see depending upon the combination, you can get between 3,500 and 10,000 lux of light.

The Comfort Lens cuts down on the glare of the light – it provides a gentler and warmer light, whereas the High Energy Lens is brighter and harsher but provides more lux.

If you are new to light therapy the best thing to do would be to start on the Comfort Lens at low intensity and gradually work your way up until you feel comfortable enough to use the 10,000 lux.

As always with SAD lights, the light should be positioned off to the side so you aren’t staring directly at it. It is meant to be no closer than 6 inches and no further way than 24 inches for your face for best effect.

For most people 30 to 60 minutes, in the morning, is a productive light therapy session. But try it out and see how you get on.

All you need to do is plug it in, turn it on and off you go!

The Good

As alluded to above the variation of light the Verilux HappyLight Liberty provides is quite unique. It emits the highest concentrated amount of light recommended (10,000lux) whilst also giving you the choice of a lower setting as well as a filter to soften the light. So there really is the perfect fit for everyone.

The light is white and natural and the four light settings mean it can be used for light therapy in the winter and as a general lamp to read by in the summer.

Changing the lens is surprisingly easy. Simply get a fingernail or small coin under the surface, snap it out and put the new one in. Once you’ve done it a couple of times you can change the lens in about 15 seconds.

The HappyLight Liberty is also compact, lightweight and portable. The base is around six inches wide so doesn’t take up a lot of room and won’t overcrowd a desk or bed side table. It is easy to carry from room or to take away with you (as long as there is a power source to plug it into).

Another nice little feature is that it can be wall mounted. It has two slots in the back that you can use to hang the light if you so wish. It can also be tilted backwards or forwards for optimal angle. Again this is a quite unique factor among SAD lights as most other lamps can only be titled away from you.

The optimal position for SAD therapy is slightly above eye level and tilted down, so taking into account the fact the light can be wall mounted and tilted backwards and forwards, it really is easy to get this light set up in a great position to receive your light therapy.

The fluorescent bulb contains no UV rays and is rated to last for 10,000 hours. The light also gives off no ozone/ions or smell, is easy to use and has clear and specific instructions.

The Bad

There really isn’t a huge amount to feature here although if this is the first SAD lamp you have bought it might take some adjusting to the light as it can be a bit overwhelming especially when on its full setting of 10,000lux.

One of the possible side effects of light therapy is headaches and some users have reported suffering them after first using the Verilux HappyLight Liberty 10,000.

If you are anyway unsure about this, the best thing to do is to easy yourself in gently. Start with the Comfort Lens and low intensity setting and the light placed out of your direct eye line around 24 inches away.

Then gradually bring the light closer making sure you are still comfortable with it and, when you are happy, increase the intensity and/or lens.

There is no timer on the light – not a big issue – but many SAD lights do come with timers and it does need power from an outlet as there is no option for batteries.

Replacement bulbs are pricey too. They are only manufactured by Verilux, so you have to by from them and they cost around $24.

The Beautiful

The light is tall and narrow and the base is very stable. Not much to complain about in the looks department. It is well made and very durable and will survive the occasional drop or topple.

A really nice looking light whether it be on your desk or wall mounted, it fits in to the setting naturally and inconspicuously.

And Does It Work?

It has a huge amount of positive feedback from users and is one of the most popular SAD lamps on the market. It helps with sleep and energy levels and generally lifting the mood during winter months.

If you do a bit of research on the internet you will find it is not just me who is giving this light the thumbs up. At least nine out of ten reviews do the same.

SAD charity SADA have released figures showing that light therapy is effective in up to 85% of diagnosed cases of Seasonal Affective Disorder. This is backed up by study after study that show light therapy makes a difference to those suffering with SAD:

In short – the chances are it will make a difference for you!

The Verdict



Variation of light to meet all needs
Light may be overwhelming at first
Provides 10,000 lux light intensity
No timer
Very easy to use
No battery option
Great design
Replacement bulbs are pricey
Lightweight and portable
Can be wall mounted
Can be tilted 15 degrees backwards and forwards


Verilux has a great reputation when it comes to SAD lamps and they have again excelled themselves with this product. The flexibility and variation of the lighting means it is suitable for everyone. It is well designed, easy to move around, solid and durable and provides up to 10,000 lux of light. All at a reasonable price.

No product is ever perfect, so as ever there are a couple of little niggles, but these really are minor.

It is very highly recommended by me indeed.
