THE SKY PORTAL
The candle was only half the answer.
One light that gets both your mornings and your evenings right. Bright sky wavelengths when you need to be sharp, warm and calming when you need to wind down but still see what you're doing.

YOU KNOW THE MOMENT
The overheads click off. A match strikes. And the whole room seems to breathe out, along with your Soul.
That exhale isn't just in your head. It's your body recognizing a signal it has read for thousands of years: warm, low, amber light means the day is ending. You've been giving it that signal on purpose, every evening, because you can feel the difference.
Here's what almost nobody tells candle lovers.
That same instinct, the one that's never once led you wrong at night, has been trying to tell you something about your mornings too.
Your body doesn't set its clock in the evening.
It sets it in the light of day.
Deep in your brain sits a master clock that decides when you feel awake, when you feel sleepy, when your energy rises and when it falls. It doesn't run on willpower or coffee. It runs on light and it's most powerfully set by the bright, sky-blue light of morning and midday.
Which is exactly the light modern life has quietly removed.
CLEAR DAY OUTSIDE
50,000–100,000
units of light
AT YOUR DESK INDOORS
100–300
units of light
Your eyes adjust, so it feels bright enough. It isn't. To the clock that runs your body, a normal indoor day reads like a long, dim, endless dusk.
You've been protecting your evenings beautifully. But you can't out-candle a daytime light deficit.
THE MECHANISM
Cells in your eyes that have nothing to do with seeing.
Their only job is to measure the light around you and report the time of day to your clock. They're tuned to the bright blue-cyan of a midday sky.
When they get that signal in the morning, your whole rhythm sharpens. You get a bigger swing between fully awake during the day and fully ready to rest at night, the exact rhythm your evening candles are trying to complete.
The research keeps pointing the same direction:
HARVARD STUDY
Ordinary evening room light delayed people's natural wind-down signal in 99% of cases and cut it short by around 90 minutes.
You already solved this one. It's why you light candles.
THE LARGEST LIGHT STUDY EVER DONE
Tens of thousands of people wearing sensors for years. A clear pattern: bright days and dim nights predicted better outcomes. Dim days and bright nights predicted worse ones.
MORNING LIGHT STUDIES
Better, steadier sleep that same night for the people who got brighter mornings.
Bright days. Dim nights. That duality is precisely what your body craves and precisely what indoor life inverts.
You've got the "dim nights" part handled.
THE SKY PORTAL
One light. Sunrise to lights-out.
The Sky Portal is built around a simple truth your body already knows: the right light in the morning looks nothing like the right light at night. That's why we built the two-in-one and it changes with your day instead of fighting it.
BY DAY
During the day the Sky Portal emits bright, energizing white and cyan light that mimics the wavelengths of a clear blue sky.
BY NIGHT
After the sun sets, the Sky Portal emits a calming amber with deep red wavelengths to support melatonin production and deeper sleep at night.
Because let's be honest: candlelight is beautiful, but you can't read by it. So when you need to see after dark, you reach for the harsh ceiling light and undo the whole mood in a second. The Sky Portal's amber mode is the light that was missing in between. Gentle on your clock. Warm on the eyes. Bright enough to get things done.
Candles for how the room feels.
The Sky Portal for everything you still need to do.
Fair questions.
"Isn't this just a bright lamp? I already have those."
A normal lamp is built to help you see. The Sky Portal is built to be read by the clock cells in your eyes. It's the spectrum and the timing that matter, not just the brightness. Most "warm white" bulbs still throw a strong daytime signal at the wrong hour. The Sky Portal gets both the signal and the timing right.
"I get outside sometimes isn't that enough?"
If you're getting real morning and midday light every day, you're ahead of almost everyone. But most of us spend our brightest, most clock-sensitive hours indoors, under light that reads as dusk. The Sky Portal is for those hours, the working, indoor middle of the day that's hardest to fix.
"I don't want more harsh tech in my calm home."
Neither do we. That's the whole reason candles feel the way they do and it's the standard we held the Sky Portal to. Bright and clean when the day needs it. Warm and quiet when it doesn't. It's on your side, not in your face.
"Is this really worth it?"
You already invest in how your evenings feel. The Sky Portal is the same instinct, pointed at the two-thirds of your waking life you haven't optimized yet. At $290 with a 100 day home trial and 5 year warranty, that's less than most people spend on the evening side in candles alone.
Imagine a day that reads correctly from start to finish.
MORNING
You sit down with your coffee beside the Sky Portal, and your body gets the bright, sky-like signal it's been starved of, the one that tells your clock, clearly, it's daytime, wake up.
WORKDAY
Instead of dim, dusk-like indoor light dragging on your energy, you've got a proper daytime signal at your desk.
EVENING
The Sky Portal fades to amber. The overheads stay off. You light your candles for the feel of the room and you still have a warm, easy light bright enough to finish your book, answer the last email, or read to your kid without a single harsh bulb undoing the calm. The room breathes. You along with it.
Bright days. Warm, usable nights. The exact rhythm your body evolved to expect. The Sky Portal has you from the first coffee to the last page, handled by one light.
You already trust your instinct after dark. This is what it looks like to trust it all day long.

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.
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.

"If you are a desk worker, you need this. I love this light. It made me dramatically more interested in sitting at my desk. I love the construction of the light and being able to change the color to match the time of day. It’s a boost to my well being and productivity."

“Before purchasing, I spent many hours researching and trying stimulating (white) and relaxing (amber) lights and can say there are very few lights on the market that can compete with the Sky Portal. The quality of light emitted is fantastic, the build quality feels great and there's a wide range of colour temperatures and intensities to dial in. I’ve now recommended the light to multiple other friends and would recommend it to anyone who is concerned with the health impact of their lighting (e. g. circadian rhythm)”

“I have had the Sky Portal now for around 4 weeks and love it. I have been using it every day when it is rainy or cloudy and when in front of my computer. I especially use it at night on the low brightness red to wind down before retiring for bed. I have been falling asleep faster and getting a much better night sleep since using it. Huge help in restoring circadian rhythm.”
