The light your screen forgot.
Screen light ages skin and tires eyes. SpectraFill™ For Monitor is the full-spectrum, app-synced light system that clips onto your monitor — adding back the healthy wavelengths your screen leaves out by day, and taking blue light out of the equation by night.

The Sun Comes First
One promise before anything else: SpectraFill works with sunlight — never to replace it. Real daylight, outdoors, is how your body keeps time and renews itself, and no device can match that. SpectraFill is here for the indoor hours when you can't get outside.
- Get outside in daylight every day, especially in the morning, ideally without sunglasses (don't look straight at the sun). This is your foundation.
- Use SpectraFill for your screen hours, on top of that.
Even at full power, SpectraFill adds only a few percent of the light you'd get standing in outdoor shade. It's a supplement, not a sun — and that honesty is exactly why it works.
Why it works
Daylight has a full spectrum. Your screen doesn't. Screens build every image from just blue, green and red, and skip the rest. The violet your eyes use to keep time, and the red and near-infrared your cells use for energy and repair, are almost completely missing — in the violet range, a screen gives you hundreds of thousands of times less than outdoor shade. SpectraFill doesn't block your screen's light. It completes it.
| What reaches your eyes | Screen alone | Screen + SpectraFill |
|---|---|---|
| Violet (daytime cue) | Almost none | Added |
| Red & near-infrared | Almost none | Added |
| Blue | On its own | Balanced |
A note on how this works. The studies in our research library used a range of doses — some high, some low. SpectraFill operates at low, continuous intensity. At these levels, we don't claim the high-dose outcomes (collagen, anti-aging protocols). What low-dose, sustained light can plausibly engage is signaling — the light-sensing pathways in your eyes and skin that respond to the presence of a wavelength, not to a large dose of it. That's the mechanism we design for.
Violet
A daytime signal that helps your eyes and body clock know it's daytime.
Deep red
Supports the energy centers (mitochondria) in your eyes and skin, where screen light strains them most.
Near-infrared
Invisible light in the wavelength range studied for cellular signaling and skin support — reaching a little deeper, passively, while you work.
We use exact wavelengths instead of a blurred mix, so the light is strong right where your body uses it. And there's no UVB — SpectraFill is made for your eyes, not as a tanning lamp.
And your skin
Screen light doesn't just tire your eyes — over the years it can age your skin, too. Screens and indoor LEDs are heavy on blue light but give off almost no infrared, and that missing infrared is part of what makes everyday screen light hard on skin. Outdoors, blue light always arrives paired with infrared; SpectraFill brings that pairing back to your desk. SpectraFill isn't a red-light panel or a face mask — those give an intense dose in one short session. It works the opposite way: a gentle, continuous dose of red and near-infrared while you work. Over a week of normal screen time that quietly adds up to a meaningful amount — enough to help support your skin's balance and resilience, with no extra routine.
Working with your body clock
Your body runs on a daily rhythm — your circadian rhythm — and it sets that rhythm mainly from the light your eyes take in. Bright, full-spectrum light says "daytime"; warm, dim light says "evening." Screens blur the signal: bright and blue-heavy late at night, missing the daytime wavelengths by day. SpectraFill helps put the rhythm back. By day, the bar adds the violet and full-spectrum light your body reads as a clear daytime cue. By evening and night, the Mitolux App eases blue out of your screen while the bar shifts to gentle red — a calmer signal as you wind down toward sleep. Used together with real daylight outdoors, your light finally matches the time of day, the way nature intended.
Setting up SpectraFill For Monitor
- 1. Mount. Rest the bar on top of your monitor so the counterbalance arm sits on the back edge. Slide it to center.
- 2. Connect. Plug in USB-C — any 5V/2A port or charger works. (Power only, no data.) The bar turns on automatically.
- 3. Power. Slide the button to turn on/off.
- 4. Select. Long-press the button to change mode; short-press to change brightness.
What's included
- SpectraFill bar (Model PM-01)
- USB-C cable (5V/2A)
- Double-sided mounting stickers
- Quick Start Guide and Owner's Manual
- Mitolux App for Windows & Mac, free — mitolux.com/pages/app
Does it fit my monitor?
It rests on most flat monitors 24" and up. For thicker frames, use the included stickers instead of the counterbalance arm.
A simple rule for brightness
Use the strongest setting your eyes are comfortable with for the light in your room. In a bright room that's usually a higher level; in a dim one, a lower one. A higher setting also gives a little more infrared — so when your eyes are happy with more, your skin gets a bit more, too.
Long-press the button to switch modes
380 · 405 · 670 · 760 · 810 · 830 nm — all six wavelengths
Your everyday setting for work and screen time. Designed for all-day use.
670 · 760 · 810 · 830 nm — red and near-infrared only
Violet turns off. Doesn't disrupt your sleep signal — use it in the evening.
760 · 810 · 830 nm — near-infrared only, no visible light
The bar looks off but keeps working — ideal for color-critical work or a dark room.
| Brightness level | Best for |
|---|---|
| 25% | Dark rooms / late evening |
| 50% | Most rooms |
| 75% | Bright offices |
| 100% | Very bright spaces |
Short-press the button to cycle through the 4 brightness levels (long press switches modes). The bar remembers your last setting.
One system: the bar plus the app
SpectraFill is a bar plus the free Mitolux App — together, one system. The bar adds the light your screen is missing. The Mitolux App calms your screen after dark, so you don't need blue-light glasses.
Day
Your screen looks normal.
Evening
The app lowers your screen's blue and green.
Night
The app warms your screen to red only.
Your day with SpectraFill
| Time of day | Bar mode / Mitolux App |
|---|---|
| Morning & workday | Day / Day |
| Late afternoon / evening | Night / Evening |
| Before bed | Night / Night |
| Dark room or color work | Invisible / As you like |
Set the bar with a long-press; set the matching mode in the Mitolux App. Prefer not to think about it? Let the Mitolux App follow your local sunrise and sunset automatically.
Everyday tips
- Sunlight first — get outside in daylight every day, ideally without sunglasses, so the full spectrum reaches your eyes.
- Day mode for work; Night mode from the evening onward — and set the Mitolux App to match.
- Skip blue-blockers by day — during daytime it's best not to wear blue-light or tinted glasses, since they also block the violet light (around 380nm) you want from both daylight and Day mode. If you prefer to wear glasses, choose UVA-passing lenses such as Vivarays.
- Keep the bar just above your screen, facing you.
- A little every day beats long, occasional sessions.
What to expect
First days
You'll likely notice your screen feels easier on the eyes, and your desk feels warmer and more comfortable.
First weeks
Using it feels natural — like opening a window you didn't realize was closed.
Over time
The benefits for your skin and cells build up slowly, the way sunlight does — from gentle, daily use.
Everyone is different, and light is just one part of a healthy day. The idea is simple: a little more of the right light, every day.
Built clean, on purpose
SpectraFill sits close to your eyes for hours, so we built it clean:
- Flicker-free — steady light, no flicker or strobing (no PWM).
- Low-EMF — designed to keep electrical emissions low at your desk.
- Power only — USB-C power, no data, no wireless.
- No UVB — and tested to the safest light-safety class (IEC 62471, Risk Group 0). Even its violet light stays far below international safety limits.
Care & maintenance
- Clean the lens with a dry, soft microfiber cloth only — no liquids or sprays.
- Keep away from moisture, steam, heat and direct sunlight.
- Unplug by holding the connector, never the cable.
- Store in a dry, padded place when not in use.
SpectraFill™ Mobile
The Spectrum Bar for your phone & tablet. You spend hours on smaller screens too, and they leave out exactly the same wavelengths your monitor does. SpectraFill Mobile clips onto your phone or tablet and restores the same six wavelengths — the same benefit, now in your hand.

SpectraFill™ For Monitor — frequently asked questions
Yes. Day mode is made for all-day use, and SpectraFill is tested to the safest light-safety class.
At night, no — the Mitolux App's Evening and Night modes calm your screen at the source. By day it's better to go without blue-blockers, since they also block the violet light you want; if you do wear glasses by day, choose UVA-passing lenses such as Vivarays.
No. Real daylight is the foundation; SpectraFill is for your indoor hours. Get outside in daylight every day.
It rests on most flat monitors 24" and up. For thicker frames, use the included stickers.
There's no UVB. The violet you see is mostly visible light, kept far below international safety limits.
Yes — turn the brightness down, or use Invisible mode for no visible light at all.
It doesn't need to be. The goal is the right wavelengths at a gentle, safe dose — not a bright lamp.
No. It's free for Windows and Mac at mitolux.com/pages/app.
Both share the same six wavelengths. For Monitor is for desk use, hands-free. See SpectraFill Mobile →
The same light, now in your hand.
SpectraFill™ Mobile is the Spectrum Bar™ for your phone and tablet. You spend hours on smaller screens too, and they leave out exactly the same wavelengths your monitor does. SpectraFill Mobile clips onto your device and restores them — battery-powered, portable, ready wherever you go.
Same 6 wavelengths as For Monitor · 3 modes · built-in battery · 24-month warranty
Before you clip it on: SpectraFill Mobile fits any phone or tablet. If your rear camera isn't in the top-left corner (similar to iPhone), the bar will sit over it while clipped on — see the compatibility check below for what to expect.
The Sun Comes First
One promise before anything else: SpectraFill Mobile works with sunlight — never to replace it. Real daylight, outdoors, is how your body keeps time and renews itself, and no device can match that. SpectraFill Mobile is here for the indoor hours when you can't get outside.

Even at full power, SpectraFill Mobile adds only a few percent of the light you'd get standing in outdoor shade. It's a supplement, not a sun — and that honesty is exactly why it works.
Is my phone compatible?
SpectraFill™ Mobile clips onto the back of your phone, right where the rear camera sits — and it fits securely on any phone or tablet. The only thing that changes is whether it covers your rear camera while it's clipped on. Camera placement varies by phone model and brand, and changes with almost every new release, so instead of checking by model name, check by looking.
Quick check
- 1. Look at the back of your phone.
- 2. Find the camera module — the cluster of lenses.
- 3. Camera on the left — it clips on without covering the camera. (iPhone is a good reference for what this looks like — it's consistently on the left side.)
- 4. Camera centered, full-width, or on the right — it clips on and works exactly the same, but it will sit over your rear camera while it's attached, so that camera won't be usable at the same time.
What about iPad?
iPad is different from the phone market. Instead of dozens of manufacturers and camera layouts, Apple has kept one consistent iPad design across generations — and that consistency is exactly what makes checking unnecessary. SpectraFill™ Mobile fits every iPad model without exception, so if you own any iPad, from any generation, you're good to go — no need to check camera placement the way you would on a phone.
Do I need to remove my case?
Yes. SpectraFill™ Mobile clips directly onto the frame of your phone or tablet, and needs direct contact to sit securely and stay aligned with the camera. With some phone and tablet cases, it won't fit properly — so remove the case before attaching it, every time.
Why it works
Daylight has a full spectrum. Your phone doesn't. Screens build every image from just blue, green and red, and skip the rest. The violet your eyes use to keep time, and the red and near-infrared your cells use for energy and repair, are almost completely missing — in the violet range, a screen gives you hundreds of thousands of times less than outdoor shade.
