Circadian aligned lighting for sleep and productivity anywhere... anytime.
“Been following the company for a while and bought this utterly game changing device
before a 13 hour international trip. I couldn’t be more impressed with how much having this device helped with the total reversal of my circadian rhythm with ease. No hotel lighting is going to help with that internal clock changeover. Highly recommend.”

and night companion”
KATIE L. | Verified Buyer
“I love using it during the day while I work on my laptop to feel alert and productive. Then at night, warming down with the amber light to prepare my eyes for sleep. The warm light is like a candle light, so soothing, Highly recommend for anyone looking to incorporate a little light therapy.”
“This little device is designed like an iPhone Max, but with healing light frequencies instead of a screen (can also charge your actual phone). This thing is fantastic, and boosts my mood within minutes when set to white light mode.”

“A device for the weekly road warrior at a price point for someone who wants to stack as many sats as possible. Truly exactly what I was hoping for. Helps wake me up to start the day and gives a healthier alternative with the amber light to end the day. Hotel fluorescents be damned!”

Jet lag isn't really about lost sleep.
It's about your body clock being on the wrong schedule. And when this clock controls if you feel awake, alert, hungry, or tired, the fallout of getting it wrong can be brutal.
It can take days to calibrate to a new city.
Days you're supposed to be on vacation, going on adventures, building core life memories.
Or days when you're traveling for work and need to be on your game to make sh*t happen.
How do we destroy Jet Lag for good?
The answer is Circadian Aligned Light.
The Sky Portal Mini gives your body the light it’s craving to align your circadian rhythm whenever and where ever you need them.
Its bright white light is tuned to the wavelengths of a blue sky, unlike the toxic light emitted from screens and hotel lighting.
The first morning after you land, sit passively in front of the Mini for 10 minutes and watch it do more to reset your energy levels than coffee, a cold shower or any medication you can buy.
At night, switch it to amber mode for a warm and comforting light with zero blue that supports melatonin production.
So even if you're working on a laptop in a hotel room, in the middle of the night, halfway around the world, your sleep remains optimized.
It’s ultra-portable, fits in your carry on and even doubles as a power bank.
Your Sky Portal Mini is waiting.
Don't Take Our Word For It.
“Powerful compact light”
DIANE P. | Verified Buyer
“Easy to use, portable and very powerful light. I use it every morning on my commute and will be packing it in my suitcase every time I travel.”
“Purchased this device hoping it would help with my seasonal blues. I look forward to my morning coffee and skylight mini time. My wife thinks I’m insane but it works and she married me so… luckily for me she really enjoys the amber setting at night. We no longer use the lights in our house and just turn this on while we wind down at night. It’s a vibe.”

Frequently Asked Questions
How do I use my Sky Portal Mini?
For daytime use, set the Sky Portal Mini 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 settings 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.
It also doubles as a portable power bank to keep your other devices charged on the go.
How long will it take to see results?
Many people feel the effects of the Sky Portal Mini 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 Mini 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.
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 Mini 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.

Can I use my Sky Portal Mini worldwide?
Yes! The Sky Portal Mini is compatible with both 110/120V and 220/240V (adapter not included).
Can I take the Sky Portal Mini on a plane?
Yes. The Sky Portal Mini is safe to bring on a plane, but make sure to pack it in your carry-on, not your checked luggage. Since it contains a built-in battery (and doubles as a power bank), it needs to stay with you during the flight. Just toss it in your bag and enjoy better light wherever you land.
It is fantastic for jet lag so you'll want access to it at all times either way.
