Meet Loop. Your circadian light.

As seen in:

Bring the benefit of daylight to your desk

Loop is a new kind of lamp that mimics sunlight to support your circadian rhythm. Place one on your desk and just like that you’re getting the light you need to sleep and perform better.

Getting started

What to expect

Place Loop on your desk, or wherever you spend most of the day. During the initial set-up, Loop will calibrate its light-schedule to your time-zone. Setup is easy with our connected ap.

8:30 am - 4:30 pm

Brighter days with Loop

During the day Loop shines a bright blue-sky colour rich in the wavelengths that set the circadian rhythm. 





4:30 - 6:30 pm

Wind down naturally

Loop's spectrum gradually adjusts from blue-sky to a warm amber glow. This virtual sunset signals to the brain that it's time send that last email and call it a day.

Better light = better life

Improve sleep

Users report falling alseep faster and sleeping better. That's because light sets the circadian rhythm, which regulates your sleep cycle.

Mental Health

 Light massively influences our mental well-being. A healthy relationship with light reduces risk of depression and other mental illnesses.

Weight loss

Light regulates your appetite and metabolic rate, making it a vital—but often overlooked—part of maintaining a heathy weight.


Kiss that sluggish feeling goodbye. Studies demonstrate that improving your relationship with light improves energy levels.


A healthy relationship with light is a powerful predictor of your healthspan, reducing your risk of heart disease, cancer, and other diseases.


Have more light-bulb moments with better light. Supplementary light can improve cognitive performance, reaction time, and productivity.

Real people. Real results

My sleep improved and I found myself more focused during the days. It doesn't hurt that it's a beautiful product - I had the coolest looking desk in the lab!

One of the most effective sleep devices! I am pleased to report that my sleep length has improved from an average of 6.45 a night to an average of 8 hours.

I could not speak highly enough about Loop. I work in a studio without any windows and Loop has been a game changer. It's sexy, it doesn't take up a lot of room.

How it works

Loop's designed is based on the latest circadian science, in collaboration with experts.
Meets emerging circadian standards
Third-party lab tested

  • Exceeds Brown 2019's recommendation of ≥250 M-EDI during the day and ≤10 M-EDI in the evening in a real-world setting. 
  • Meets the WELL Building V3 recommendation of ≥275 EML in a real-world setting.

Independently testing by UL Solution's Circadian lab.  

Not just a colour
changing bulb

There's plenty of colour-changing bulbs on the market. But none can produce Loop's biologically optimised spectrum for circadian alignment.
Loop supplements your existing lighting—filling the blue-sky dip—to bring any office up to optimal light levels . At night, Loop dynamically transitions to a <10 m-EDI light, in line with evidence based recommendations.


Delivery and returns

How does the subscription work?

You pay a monthly fee for a Loop. You can cancel anytime, but if you do you'll have to return your device.

Osin retains ownership of your Loop, so if there's any hardware failure, we'll repair or replace it as long as you're subscribed.

Is the subscription rent to own?

No. It’s more like a gym membership. You can cancel anytime, but if you do you'll have to return your device. 

If you've been subscribed for 12-months or more and decide you want to buy your Loop, you can purchase for 50% off.

If subscriptions aren’t your thing, we still offer the option to purchase Osin Loop.

Why do we ask for ID verification?

Before we send a brand new product to someone trial, we'll ask for photo ID and a proof of address. This is a security measure to prevent any monkey business.

What happens if I cancel

If you decide to cancel, we’ll send you a return shipping ticket, and you’ll send the Osin Loop back to us.

Failure to return your Loop or returning a damaged Loop will result in a bill for the cost of the damages.

Does Loop have a warranty?

We offer a three-year warranty that covers any mechanical fault.

For subscribers, we'll cover any mechanical fault as long as you remain subscribed.

Where do you ship?

We’ve partnered with DHL to offer shipping almost everywhere in the world. Shipping is calculated at checkout, and you’ll receive a tracking number as soon as your order is fulfilled.

What payment methods do you accept?

We accept card payments (Visa, MasterCard, and American Express.) We also accept Shop Pay, Apple Pay, Google Pay and Paypal.

What about duties and taxes?

In New Zealand, Australia and The United States, you will not pay any import taxes on your order.

In other jurisdictions, you may be liable to pay taxes. Check the rules where you live for more details.

We know that might be frustrating, but Osin is not responsible for the import duties and taxes imposed by governments. If you return your Loop, we'll refund you for the value of your order but we won't cover any taxes you incurred.

What if Loop isn't what I expected

We offer 30-day free returns. Contact us at and we'll send you a shipping ticket.
