Need a remote
"It's a good light and I use it as my primary desk lamp all day long, but I really hope that it comes with a remote because I constantly have to stand up, walk behind the monitor, and adjust the hue and intensity. 4 stars from me."

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 white light spectrum ever put in a stationary lamp, keeping your focus sharp, your mood lifted, and your sleep cycle intact year-round.
Our custom White channel removes the 430–460nm blue hazard that strains eyes and disrupts sleep, while boosting the beneficial 415nm violet and 480nm cyan bands 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.
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 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?
The Chroma Sky Portal is designed based on the large 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.
Prioritize your mental and emotional health with the power of light. Elevate your mood, boost productivity, and improve your sleep quality by shifting your light environment.
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.
The Sky Portal uniquely promotes circadian and mental health through opsin stimulation, balanced with NIR and 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.
What is the guarantee on the Sky Portal?
We are confident that your experience with the Sky Portal will be nothing short of extraordinary. However, we understand that personal preferences may vary, and we want you to have complete peace of mind when you choose us to assist with your circadian rhythm.
With our 100-day Satisfaction Guarantee, you can embark on your journey to enhanced well-being without hesitation. If, within the first few weeks of using your Sky Portal, you find that it doesn't align with your expectations or preferences, you have the option to return it to us.
How long will it take to get my order?
It depends on where you are. Orders processed here will take 3-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.
Can I use my Sky Portal worldwide?
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 our Sky Portal Mini battery powered device.
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, our Skylight floor standing lamp is an ideal solution for larger rooms.

Positive effects on focus
"Sitting at a desk all day for work and not getting adequate sunlight in my apartment, the portal has been a game changer. Maybe placebo or not, but i feel more focused and have less eye strain staring at my multi monitor setup. It also helps with lighting me up on zoom calls. My gripe is similar to others where the controls are on the light itself. It would be so much more convenient to have a small remote that can lay on my table to adjust color temp and intensity. Overall though, im very happy with the product."
All day focus and evening wind down
"First the color fidelity is great, but most important is the consistent focus this gives all day. The manual adjustment is important too as you can vary the spectrum to wind down at the end of the day with a relaxing amber light as well. It's the slilent coworker that help you get things done!"
Love the light and energy
"Love the light and energy /focus"
Bringing the sunshine inside
"Living in rainy Oregon, I was genuinely surprised by how much brighter and more energized I felt after setting up the Sky Portal 2. 1. It's become one of those small changes that has made a noticeable difference in how my workspace feels each day."
Circadian Office Boost
"I love my Portal. It’s made working at a computer a total change and I’m finding myself actually falling asleep earlier and easier because the exposure to the bright light during the day. My only feedback is that the device gets hot after several hours of use, and I’m concerned it won’t last super long because of wear and tear on the circuit board."
Instant impact
"I got the sky portal 2. 1 a couple days ago and it has had an instant impact. I set it up and worked from home yesterday. Normally my job will make me angry a few times a day at least. Lazy people just wear me out. All of a sudden yesterday I noticed about 2pm that not only had I been working continuously since around 9am, but I didnt remember getting mad and telling myself to quit yet. Had to think about it for a minute, but I didnt get mad all day. Rarely can I work on that computer for 5 hours straight either. Only thing different was the sky portal 2. 1. Im at it again today and its my off day. Chroma might have made too good of a light here. Be warned, your productivity will go up in a meaningful way. Im thinking about purchasing the battery powered sky portal to take to work. The red portal I ordered will be delivered today. Im excited to run both lights for a full day tomorrow. The thing is they seem to render immediate results. Im impatient and immediate results is exactly what im looking for. P. s. when you make an order with Chroma you get a handful of cool stickers also. Im a sticker guy. I think Chroma is trying to get on permanent with me!!!"
If you spend a significant
"If you spend a significant amount of time working from home, this is a must-own item. I bought two for my wife, for her home work desk and we love them. The light is strong but pleasant and can be adjusted. The adddd amber is rich and calming. Would strongly recommend these."
Great product
"Getting used to the bright light in your eyes from the corner takes a few days to get used to but it's not extremely bothersome even in that time. Have noticed better recovery from sports fatigue and general better alertness during the day."
Essential for everybody
"We live in Estonia, with total darkness during the winter. Sun sets at 3. 30 pm. We just can´t survive here without additional help with light. But even without this, the indoor lighting is NOT made for human biology! I think everybody needs at least the Sky Portal - its affordable, and it makes a big difference!"
