The Second Best Light Of Your Life…

Obviously, the Sun is the best light we have available to us as humans, but the Blue/White Sky Portal is a close second when it comes to white lights!

Did you know it is ~100x brighter outside than it is inside? Now you have a way to tell your brain the sun is shining while you’re inside! Feel happy, alert, and more focused, then be ready to fall asleep naturally when the Day Shift™ signal turns off. The Sky Portal is similar to a high powered SAD light, able to deliver well over 60,000 melanopic lux, with 480nm sky blue, blend-able with our extended red HiFi White.

30 Day Satisfaction Guarantee:

We’re confident you’ll love your Sky Portal within the first few weeks, and if you don’t, you can send it back to us for a full refund.

Day Shift

Tell Your Brain To Wake Up!

The Blue/White Sky Portal is focused on circadian function with 480nm sky blue plus an ultra pure white light. The blue channel can be blended with our ultra high fidelity white for a more cloud like appearance, or use it set to 90% white, and 10% sky blue when you want an ultra-high fidelity non-harsh white light with no “cyan gap”.

Why does 480nm Sky Blue Promote a Natural Circadian Rhythm?

Light blue (sky blue) wavelengths stimulate melanopsin containing cells, which act as wakefulness/sleepiness controllers. These are the key wavelengths and photoreceptor pathways that when stimulated, promote alertness and circadian rhythm regularity.

Set to max brightness on the sky blue channel, melanopic lux is equivalent to ~60,000 lux without seeming as bright or harsh since there is no green or dark blue. This far exceeds the common minimum recommendation of 10,000 lux.  Our customers say the sky blue channel on 100% reminds them of the sky.

The Sky Portal uniquely promotes circadian and mental health through stimulation of light blue wavelengths by drowning out harsh short-wave dark blue light from your ambient lighting and screens, by causing your pupils to contract with natural long wavelength sky blue.

What is a “Cyan Gap” & Why Do I Care?

Great question. In short, because of how white LEDs are built, there is a harsh gap in the 480nm sky blue range.  This range is the exact tip of human melanopic sensitivity.  This means that on top of it already being 100x darker inside than out, there’s also a massive gap in the light that responsible for the regulation of circadian rhythm,  witch tells your brain that you’re awake.

Ultra High CRI Light With Extended Reds for Natural Color Rendering

Our white channel is tuned to exceed the performance you’ll find in photography lights! It has deep reds boosted for enhanced r9, meaning skin tones look more healthy and natural (e.g. on a Zoom call) vs most other indoor lighting with poor red reproduction.

With sunlight defined as a perfect light, the Sky Portal aims to be as close to perfect as possible, this means colors will render more accurately under the Sky Portal.  No more green/yellow tint in your skin, art, and food, and no more eye strain caused by the harsh light spectrum found in traditional LED & florescent lights.

The Sky Portal is Much More Than a S.A.D. Light:

This is more than a S.A.D. light. This is a portal connecting the interior of a building to a natural outdoor setting.

The idea that S.A.D. is a condition that only effects a small segment of the population is misleading.  Nearly all people feel and perform worse in poor light environments where their circadian rhythm is disrupt, we only give it a special name when these normal reactions cross a somewhat arbitrary threshold.  Better light leads to a better life.

What happens if your circadian rhythm is out of whack?

A healthy circadian rhythm is vital to maintaining long-term health.  A disrupted circadian rhythm leads to worse sleep, a foggy mind, and worse health outcomes. Strengthening circadian rhythm is one of the most effective wellness “biohacks”.

Circadian Rhythm and Sleep

Better light during the day means better sleep at night.  Regulated melatonin production is vital for deep and restorative sleep for optimal performance and productivity throughout the day.  Let your body know it’s daytime so you’re ready to fall asleep naturally when the sun goes down.


For max circadian rhythm and sleep benefits, your Sky Portal should ideally be paired with our Carbonshade glasses that block Blue AND Green light that disrupt sleep in the evening.  You want melanopic light during the day, and you want to avoid it in the evening before you go to sleep.

    I recently received my Sky Portal light and truly love it.

    I like it, and I feel like (struggling for a good way to collect data on this) it helps quite a bit. When I leave it on for the whole day, it definitely changes how I feel in the evening, and its effect is much “softer” than having a conventional bulb scorching my eyes all day.

    I love the Sky Portal, I use it every day now that I have to work in my home office and don’t have the large windows at normal work. I find it bright but not so much that I can’t use it essentially for most of the day. No flicker. So far working wonderfully! Reminds me of the sky.

    This was my first purchase from Chroma, I now own 2 white versions and one NIR, great lights and an amazing help in the winter when there’s not enough light.

    Great device, extremely bright. Since it has configurable brightness and blue/white color mix, I’ve been able to adjust it as the light outside changes through the seasons. It’s expensive but worth it.
