The Sky Portal and the Red Portal work together to transform your indoor space into a biologically coherent environment. The Sky Portal delivers opsin-targeting white light to support daytime alertness and pure amber light in the evenings to not disrupt your circadian rhythm. The Red Portal fills in the missing piece, all-day exposure to deep red and near-infrared wavelengths that nourish your cells and allow you to effortlessly accumulate these benefical photonsthroughout the day. One sets the rhythm. The other delivers the fuel.

Precision Engineering
The Chroma Sky Portal 2.1 is a personal circadian lighting system built to anchor your biology from sunrise to sunset. Designed for desks, studios, and home workspaces, it delivers the most bio-active spectrum ever put in a stationary lamp, keeping your focus sharp, your mood lifted, and your sleep cycle intact year-round.
Its custom White channel removes the 430–460nm blue hazard that strains eyes and disrupts sleep, while boosting the beneficial 415nm and 480nm wavelengths that stimulate OPN3, OPN4, and OPN5 photoreceptors tied to alertness, mood regulation, and circadian rhythm.
The Deep Amber channel delivers a low-melanopic, 1300K warm glow with boosted 660nm Deep Red, helping you wind down at night without suppressing melatonin. Adjustable ratios let you fine-tune the spectrum from full-daytime white to pure evening amber.
With over 10,000 melanopic lux @ 10" when set to 100% white, the Sky Portal 2.1 outperforms typical SAD lamps and workspace lighting, flooding your environment with biologically potent light that supports focus, energy, and resilience through every season.
A true flicker-free driver ensures stable, comfortable illumination at any brightness. The included desk mount positions the light exactly where you need it, while the slim, durable build integrates seamlessly into your setup.
Whether you’re in the depths of winter or burning through a long creative sprint, the Sky Portal 2.1 ensures your workspace is always lit for peak biological performance.

Frequently Asked Questions
How do I use my Sky Portal?
For daytime use, set the Sky Portal 2.1 to maximum brightness and dial it all the way to daytime white while the sun is still up. This invigorating light is engineered to stimulate OPN3, OPN4, and OPN5 - non-visual photoreceptors that help boost alertness, focus, and mood.
As the sun begins to set, gradually shift the dial toward a deeper amber tone, ending with pure deep amber and boosted 660nm deep red. This transition mimics the sun’s natural progression, helping your body wind down, increase melatonin production, and prepare for restorative sleep.
After dark, DO NOT use the highly stimulating white channel, instead set the device to 100% Deep Amber and dim to a level that is comfortable.
How long will it take to see results?
Many people feel the effects of the Sky Portal immediately - especially in terms of energy, alertness, and mood. OPN4 (melanopsin) stimulation can begin shifting your circadian rhythm within the first few sessions, helping you feel more awake during the day and more naturally ready for sleep at night.
For those using it to combat seasonal dips in mood or focus, consistent daily use for 1–2 weeks is often enough to notice a significant lift. Longer-term benefits, like improved sleep quality and steadier daytime energy, build as your body adapts to a healthier light environment. The key is consistency - your biology responds best when it receives the right light cues every day.
Can I use the Sky Portal at night?
Yes, but ONLY use the device set to 100% deep amber as the white channel is highly stimulating and will disrupt sleep if used after dark.
How do I mount the Sky Portal?
For maximum optionality, the Sky Portal is designed to be able to mount on any standard photography light mount. We also include a clamp style desk mount as shown in the images.
Why would I choose the Chroma Sky Portal?
Scientifically Proven Benefits:
Our portal is designed based on the huge set of research showcasing the positive effects of Opsin stimulating light on productivity, mood, and sleep regulation. OPN4 or Melanopsin is the start of the main pathway that controls sleep wake response for a more effective Day Shift signal.
Seamless Integration:
Easily incorporate the Sky Portal into your daily routine. Whether you're waking up, working, or even playing games, it's a versatile addition to your personal light environment.
Invest in Your Well-Being:
Prioritize your mental and emotional health with the power of light. Elevate your mood, boost productivity, and improve your sleep quality with the Sky Portal.
Why does Opsin simulating light promote a natural circadian rhythm?
Cyan to Violet wavelengths of light stimulate opsin containing cells, which act as the main wakefulness/sleepiness controllers. These are the key wavelengths and photoreceptor pathways that when stimulated, promote alertness and circadian rhythm regularity. (Study)
The Sky Portal uniquely promotes circadian and mental health through opsin stimulation balanced with deep red light.
Is this just a high powered SAD lamp?
The Sky Portal is far more than a S.A.D. light. It 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 affects a small segment of the population is misleading. Nearly all people feel and perform worse in poor light environments where their circadian rhythm is disrupted, we only give it a special name when these normal reactions cross a somewhat arbitrary threshold. Better light leads to a better life. We've custom tuned the white LEDs in this device to have no cyan gap and offer excellent opsin stimulation, we then balanced that stimulating white with a powerful and relaxing Deep Amber channel.

Yes! The Sky Portal is compatible with both 110/120V and 220/240V (adapter not included).
Is the Sky Portal portable? Can I travel with it?
While technically you could it was designed for a more permanent setup. If you are looking portable for circadian-aligned lighting solutions we recommend the Sky Portal Mini.
The Sky Portal Mini is made for travel, flexibility, and tight spaces. It gives you the same powerful circadian-supporting light as the full-size Sky Portal 2.1, but in a compact, portable form you can take anywhere. Use it in hotel rooms, at your desk, in your kitchen - anywhere you need better light but can’t set up a full rig.
If you want full-room immersion at home, go with the 2.1, but if you need something to keep you aligned on the go, the Mini is the clear choice.
