The Osin Loop supplements your workspace with the light needed to align your circadian rhythm. During the day this light has been shown to:
• Improve alertness and cognitive performance (see studies 🔎: 1, 2)
• Improve mood (see study 🔎: 3)
• Alleviate sub-clinical seasonal affective disorder (see study 🔎: 4)

In the night and evening, this light can also:
• Promote melatonin production (see studies 🔎: 5, 6)
• Help you fall asleep faster (see study 🔎: 7)
• Enhance sleep quality (see studies 🔎: 8, 9, 10)
• Help you stay asleep longer (see studies 🔎: 11, 12)

Additionally, an aligned circadian rhythm helps ensure you live a long and healthy life by:
• Reducing the risk of heart disease (see studies 🔎: 13, 14)
• Reducing the risk of cancer (see studies 🔎: 15, 16)
• Reduce the risk of obesity (see studies 🔎: 17, 18)
• Reduce the risk of diabetes (see studies 🔎: 19, 20)
• Reduce risk of neurodegenerative diseases (see studies 🔎: 21, 22)
• Reduce the risk of depression and other mental health conditions (see study 🔎: 23)

Good question. Here are a few reasons why the Osin Loop is truly a one-of-a-kind product.

Evidence-based design – The Osin Loop is the only supplementary light that meets the recommendations
based on expert scientific consensus. Loop delivers >250 EDI during the day and <10 EDI in the evening.

Spectrally optimised ­– Osin Loop’s array of LEDs are spectrally tuned to the peak sensitivity of
intrinsically photosensitive retinal ganglion cells (the photoreceptors that set the circadian rhythm). Because of this, Loop achieves the same biological effects as daylight while remaining incredibly energy-efficient and visually comfortable. 

Round-the-clock support – Most products focus on either day or nighttime use. The Osin Loop provides
the optimum light around the clock, avoiding the need for two products.

Set and forget – Once paired with our app, the Osin Loop syncs with your time zone and automatically transitions between day and night modes.

Great question!

The Osin Loop is designed to emit a specific band of blue light (peaking 480 nm) to reproduce the biological effects of sunlight.
Colour-changing LEDs offer a wide range of colours, making them great for décor. However, they cannot emit light peaking at 480 nm, meaning they are not equally effective for circadian rhythm alignment.

What are commonly known as RGB-LEDs, or colour-changing LEDs, are in fact a package containing three small individual LEDs, which emit at the following peak wavelengths: 450 (blue), 525 (green), and 625 nm (red). RGB-LEDs can produce a colour that appears visually similar to Loop by mixing the 460 (blue) and 525 nm (green) channels. But because it still lacks light at 480 nm, it does not have the same biological effect as using the Osin Loop.

While many technology products opt for an annual upgrade cycle, we built the Osin Loop to be with you for the long run. Every Loop comes with a three-year warranty from the original date of purchase, but it should last much longer (if you look after it). The Osin Loop has a rated life of 10 years. In other words, every component, from the LED array to the integrated board, is rated to withstand 10 years of normal use.

Instead of releasing new models each year, we plan to continue innovating through software. As a Loop owner, you will receive all subsequent software updates.

Yes, the longer you are exposed to it the better. The Osin Loop meets the recommended levels of light based on expert scientific consensus for optimum human health (see recommendations 🔎: 1)

Despite what you may have heard, not all blue light is harmful. Blue light can be divided into two bands: blue-violet light (415-455 nm) and blue-sky light (465-495 nm). The two bands mentioned above exhibit vastly effects effects on the eyes.

Several studies have been published in medical literature demonstrating that blue-violet light can induce retinal cell death at high intensities; however, scientists still disagree whether this is a risk at the lower intensities we are routinely exposed to from devices.

On the other hand, the Osin Loop only emits blue-sky light, which in addition to being widely regarded as safe, is critical for aligning our circadian rhythms, which in turn maintain and regulate our sleep, mood and many other biological functions.

You may experience an immediate lift in energy from Loop; however, it can take up to ten days for your circadian rhythm to realign.

Set-up and Use

This 90-second video will run you through the entire set-up process.

Place the Osin Loop wherever you spend the most time during the day. For most people, that is their desk.

Position your Osin Loop 45º from your main display, at roughly an arm's length from your eyes. If you need extra help, check out this video, or contact us via the live chat.

The Osin app is necessary for the initial set-up of the Osin Loop. It is used to synchronise your Loop to your time zone.

However, once the Osin Loop is set up, you do not need to connect regularly for normal day-to-day operation. You could delete the app, and the Osin Loop would continue to perform normally.

You would miss out on some functionality, such as being able to dim your Osin Loop when in amber mode, but otherwise, the Osin Loop will work as intended.

The Osin Loop syncs with your time zone so that it automatically turns blue in the morning and goes through a gradual sunset transition till amber light in the evenings.

If your work schedule and wake times conflict with this scheduling, you might want to consider switching the Osin Loop’s time zone via the Osin app. By switching the time zone via the app, you can find a time of light delivery that works better for you.

Contact us through live chat, and we can help you figure out if the Osin Loop is for you.

It depends. We designed the Osin Loop to work for day workers who do not get enough light during the day. Unfortunately, with night shift work, there are so many types of schedules and patterns. This can vary depending on the number of days per week that you work nights, the length of daylight you get and what your weekend wake times look like.

Not currently, we’ve designed the Osin Loop to live where you spend most of your day, for most people, that means their desk. The reason for this is research shows that blue-enriched light throughout the day has many health benefits.

With that being said, we’ve had a number of people ask about scheduled turn-off/on functionality, and it’s something we plan to roll out via a software update at a later date. Even if you buy the Osin Loop now, you will receive all future updates.
