Handy talking point in the office

I have an Osin Loop and it is a real talking point in the office. I think you could add a QR code to the stand so people can quickly learn more about Osin. It's a great office solution and every desk should have one.

Things I started doing earlier: feel tired, sleep, wake up

I strongly credit the Loop for the consistent sleep I've been getting. For almost as long as I can remember, maintaining a sleep routine seemed impossible for me. Never could hack the early-to-bed-early-to-rise thing.

As a university student, my life revolves around a laptop. Pre-Loop, 1am looked like doing homework in front of a brightly-glowing screen inside an even brighter room. Deep sleep never came easy after that.

After a few weeks of using the Loop in the evenings instead of my normal bedroom lights, I actually started to feel tired when my flatmates did. Going to sleep earlier and waking up earlier has forced me, for the better, to live my life on a different schedule.

Truly had no idea how imperative proper light exposure is to sleeping at the appropriate times. Very excited for the upcoming school year. Sleeping at night makes everything easier--who knew?!

Looks Fabulous

The light looks fabulous and easy to set up. Still, too early to tell whether it work on the circadian clock but I do feel sleepier at night for the last couple of nights .

However, there is no way to setup a schedule for turning it on and off. I thought a workaround through smart plug would work but the power switch on the OSIN will not function with smart plug.

Just what I was looking for!

While completing my doctoral thesis (neuroscience of vision), my school gave me an office conveniently located close to my house, but with very little natural light! I worked long hours and found my circadian rhythm out of wack with day and night. I was thrilled to hear of an NZ-made product that understood the science of how visual pathways set the pace of alertness and sleep. Within days, Osin boosted my productivity and health, with a firm burst of blue light in the mornings that transitioned to orange in the evenings. 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!

Bright, but functions great

I think it's good for me in my dark little office, but I don't experience the advertised benefits. The light is very bright, and at times I feel like it's causing me eye strain - though normally it's fine. The light looks great and functions well.

Frequently asked questions

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 ­– The 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, the Osin 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.

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.
