So How Does the Circadian Optics Lampu Work?

Circadian Optics are a relatively new company founded in 2016 by Amber Leong and her husband Kin Mun Chew.

Leong had moved to Minnesota to attend University, and she soon noticed that the long dark winters, which often start in October and can last through until April or even May, were taking a hold.

She bought a light therapy lamp to combat SAD but thought she could do a better job of making one.

And guess what?

From that Circadian Optics were born and since their inception in 2016 the company has doubled its revenue in each of its first three years and increased its range of products.

Pretty amazing right?

The Circadian Optics Lampu is a one touch SAD lamp. Once it is plugged in a touch sensitive button on the back of the Lampu turns it on and cycles through the light settings. 

The first touch turns it on at the brightest setting, the second touch dims it slightly, the third touch dims it again and then the fourth touch turns it off. Touch it again and it turns back on again.

Pretty simple.

The design is, according to the Circadian Optics website, inspired by the sun – with a minimalist look and ‘a focus on flowing curves and clean lines’.

It provides the recommended 10,000 Lux at 8 to 16 inches, and the light is pure white with a color temperature of 5,500k – designed to emulate the color of the noonday sun. The light is full spectrum and UV rays are filtered.

Digging a little deeper.

The lamp measures 8.8 by 8.8 by 4.75 inches, weighs 1.4 lbs and uses LED lights that last around 50,000 hours.

The lamp and the adapter are both covered by a two year warranty.

The Good

For me the first thing that I noticed when I unpackaged the Circadian Optics Lampu was the look of it – it is simple, but very sleek and stylish.

The circular design is great and it breaks the mould of SAD lamps looking like medical devices – it looks like a contemporary piece of lighting that will fit nicely in any living room (or bedroom for that matter).

And it gets better…

The initial favorable first impressions extend to the build quality of the Lampu. It is very well made. It is solid, the electrical attachments are good, the light is turned on by a sleek touch sensor and the base is sturdy.

For me the size is perfect as well. The light area is large enough to make it easy to get your dose of light therapy each day and sit comfortably in the field of light, but it is still compact and lightweight enough to be able to easily move it from place to place or take it away with you if you go on holiday.

So now the part you have all been waiting for…

The light quality! And again this is top quality. The LED lights inside the white surface produce a light that is very bright, but not at all glaring or jarring. 

The light is evenly spread across the 8-inch light area and as I mentioned earlier, with a temperature of 5,500k, it emulates the white light the sun emits at noon.

And of course as this uses LED lights, which are rated to last 50,000 hours, so you shouldn’t ever have to replace them.

In short the light is wonderfully clean and clear.

What’s more:

This has three light settings, so you can ease yourself into light therapy gently if you are new to it. 

They are easy to change, simply touch the sensor on the back of the light to turn it on and then touch it to cycle from the highest light setting to the medium setting to the lowest setting and then one last time to turn it off.

The light angle is fixed, but due to the large field of light this isn’t a problem, so the angle is ideal for reading, writing, eating breakfast, etc without straining to be in the right position so your eyes are in the field of light. It makes it so much easier.

Despite the fact it is pretty lightweight it is durable and, of course, as it has LED lights there are no bulbs to break.

On top of all that:

The price point is great, especially when you take into account the quality of the light and the fact there are no bulbs to replace. It should last you a long time, so it offers great value for money.

I have had great experiences with Circadian Optics customer service as well – they are knowledgeable and accommodating and committed to making a difference to people suffering from Seasonal Affective Disorder.

The Bad

Now whilst the Lampu does have a lot to love about it, it isn’t without its faults.

So let’s dig a little deeper:

I love the look and feel of the Lampu. It is so sleek and elegant, but this does come at a small price. 

The on/off/brightness adjust button is a touch sensor area rather than a switch. It barely needs to be brushed to be triggered. 

This does take a little getting used to and you might find yourself accidentally touching it, turning it on and momentarily looking straight into the light.

But you soon get used to it and learn not to do it again.

What else?

A timer would be handy, but again I think this was down to Circadian Optics not wanting to disturb the simple and smooth design.

Also the stand is not adjustable – it is in a set position you can’t change. The ability to tilt the lamp would be a nice addition just to make it slightly easier to angle the light exactly how you want it. Although due to the big field of light this isn’t a huge issue.


At 4 inches by 2 inches the plug on the cord is bulky and a bit of a receptacle hog, if you have limited space it might make it difficult to plug it in.

And if I was being really picky the power cable could possibly be a foot or so longer.

The Beautiful

I have made no secret that I love the simple but elegant design of the Lampu. Circadian Optics are making great strides in ensuring their SAD lights look like actual modern decor that would fit in any room in the house.

But much more than that – this doesn’t just ‘fit in’ with decor, it looks stylish – very pleasant to look at (in more ways than one!) indeed.

And Does It Work?

A resounding yes! With a top notch, and large, field of light it would be harder for it not to work.

Aside from my own confirmation that this will do wonders to regulate your sleeping pattern and make you feel more alert throughout the day, there are also those of many others who report dramatic changes in their circadian rhythm, sleep and mood and energy.

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!

My Verdict

My Rating - 95%


A terrific SAD lamp

Circadian Optics are pushing the boundaries of light therapy and evidently breaking the mould in attempting to make SAD lamps look like normal lighting and they are doing a great job!

The Lampu is a terrific SAD lamp. It is simply, but beautifully, designed - you wouldn't know it is a SAD lamp, the light field itself is strong, a wonderful pure quality and large so it is easy to find a comfortable position to sit in the light and it is still lightweight enough to be able to move from room to room or take on your travels with you.

This will be a vital tool in the fight against seasonal affective disorder - go out there and get it, you won't regret it!

Other Options

At the time of writing I think this is the best overall option on the market, although it is run close by the Carex Health Brands Day-Light Sky and the Verilux HappyLight Liberty 10k.

The Carex Health Brands Day-Light Sky has a huge field of light that enters your eyes from above and the Verilux Liberty has a flexible design and great light quality. Neither of them look remotely as stylish as the Lampu though!

But all in all Circadian Optics make lots of great SAD lights.
