Your bedroom light is keeping you awake. Here is exactly why.

You have tried the usual sleep fixes.
The supplements. The apps. The blackout curtains. Maybe even the pills.

But there is one thing most people still ignore: the light they use before bed.

At night, most people are still under bright lamps, bathroom lights, and phone screens right up until they try to sleep. That keeps the brain in a more alert state when it should be slowing down.

Lampiero uses deep 670nm red light so you can light your evening with a softer, less stimulating glow instead of the harsh light most homes use at night.

The result is simple: a calmer wind-down, less overstimulation before bed, and an easier transition into sleep.

The discovery that changed sleep science

In 2002, scientists confirmed that part of the eye is specifically built to tell the brain what time of day it is.

This system is highly sensitive to blue light, around 480nm.

That is why the wrong light at night can make you feel alert even when you are tired.

That is the real mechanism behind the blue-light problem.

What most people still miss is this: the issue is not only your phone. Even many “warm” lights in the home still emit enough short-wavelength light to keep sending the wrong signal at the wrong time.

Lampiero is built around 670nm deep red light, where that melanopsin response drops to almost nothing.

Why melatonin supplements are often fighting a losing battle

Melatonin is the hormone your body produces to signal sleep. It begins rising in the evening as light fades, peaks during the night, and falls again toward morning.

But here is the problem: if you take melatonin while still exposing yourself to the wrong light at night, you are pressing the accelerator and the brake at the same time.

The supplement is trying to raise melatonin.
Your light is telling your brain to suppress it.

That is one reason melatonin often feels inconsistent.

As Dr. Andrew Huberman has noted, many melatonin supplements also contain doses far higher than what the body naturally produces, and actual content can vary widely across brands.

A simpler first step is often to stop blocking your own natural melatonin rhythm with the wrong light.

Why 670nm specifically?

Not all red light is the same. Wavelength matters enormously.

Melanopsin sensitivity peaks at 480nm and drops sharply as wavelengths increase. By the time you reach 600nm, activation is minimal. At 670nm, it is effectively zero.

That means 670nm light can illuminate a room enough to read by, change a nappy, or walk to the bathroom without triggering the biological alarm that suppresses melatonin.

In 2012, researchers found that 30 minutes of 670nm red light before bed significantly increased melatonin levels and improved sleep quality over 14 days. A 2024 comparison showed that after two hours of evening exposure, blue light kept melatonin suppressed while red light allowed melatonin to recover to more than three times the level.

670nm is not a guess. It is a specific, researched wavelength and it is what Lampiero is built around.

What this means in real life

Ordinary evening light

Good for visibility. Bad for winding down. It can make your brain feel like the day is still going.

670nm red light

Still useful at night, but softer and less stimulating for wind-down, bathroom trips, and night feeds.

Where this matters most

Questions

How to get the best results?

  1. Turn Lampiero on 1-2 hours before you want to sleep
  2. Turn off all other lights in the room, Lampiero should be the only light
  3. Read, talk, or wind down in the red glow
  4. Set the timer (30 min / 1 hr / 2 hr), it turns off on its own
  5. Give your body 1-2 weeks to adjust, your circadian rhythm resets gradually

What is blue light and why does it affect my sleep?

Blue light is the wavelength emitted by phone screens, overhead lights, and even "warm" bulbs. It signals your brain to stop producing melatonin, the hormone that makes you sleepy. Lampiero emits 670nm red light, which your brain reads as sunset. Melatonin keeps flowing.

How big is it? Will it fit on my nightstand?

Lampiero is 9.5cm wide × 12.5cm tall

Roughly the size of a coffee mug. It fits on any nightstand, bathroom shelf, or nursery table. Small enough to carry from room to room.

Is it safe for babies and children?

Yes. 670nm red light is gentle, non-UV, and produces no heat. Parents use Lampiero for night feeds, nappy changes, and bedtime routines. It is the safest colour of light for little eyes at night.

Do you ship to my country?

We ship to all EU countries with free standard delivery. Orders are dispatched within 1 to 3 business days. Delivery takes 10 to 15 business days depending on your location. You will receive a tracking number by email.

International shipping is also available in the checkout.

How bright is it?

Lampiero has 5 levels of touch-adjustable dimming, from a glow you can barely see to bright enough to read by. Most customers use level 1-2 for sleeping and level 3-4 for night feeds or reading. Plus the auto-off timer (30 min / 1 hr / 2 hr) means it turns itself off once you are asleep.

How is this different from a regular night light?

Most night lights use warm white LEDs that still emit blue wavelengths. Even "warm" light suppresses melatonin. Lampiero uses a specific 670nm wavelength: pure red, zero blue. The same wavelength as sunset. Your brain reads it as sunset, not daytime.

I have tried everything for my sleep. Why would this be different?

Most sleep solutions treat symptoms. Melatonin adds hormones. Apps distract your brain. Lampiero addresses the root cause: the light in your home is telling your body to stay awake. Remove that signal, and your body does what it already knows how to do.

When will I notice a difference?

Most customers notice a change within the first week. Some feel it the first night. The biggest shift happens when you use it consistently for 2-3 weeks, as your body's natural melatonin rhythm resets.

Can I return it if it doesn't work for me?

Absolutely. Our 30-Night Sleep Promise means you can use Lampiero every night for a full month. If you don't notice a difference, email us and we will refund you completely.

670nm Red Light and Sleep: What the Research Shows

The relationship between light wavelength and sleep quality has been studied extensively over the past two decades. The core finding is consistent: light in the blue and green spectrum (400 to 550nm) suppresses melatonin production and disrupts circadian rhythm, while light in the deep red spectrum (620 to 700nm) does not.

Key Research Findings on Red Light and Melatonin

A study published in the Journal of Athletic Training examined the effect of 30 minutes of red light exposure on sleep quality in female basketball players. The group exposed to red light showed significantly improved sleep quality and serum melatonin levels compared to the control group. Research published in PNAS by Harvard Medical School investigators demonstrated that evening exposure to blue-enriched light suppresses melatonin onset and shifts circadian timing, while red-shifted light has minimal impact on melatonin production.

Research from Rensselaer Polytechnic Institute's Lighting Research Center has shown that even light marketed as "warm white" contains enough blue-spectrum energy to suppress melatonin by approximately 50 percent. This is why switching from a standard warm night light to a 670nm red light source produces a measurable difference in sleep onset and sleep quality.

Why 670nm Specifically

The 670nm wavelength sits in the deep red portion of the visible spectrum, very close to the boundary with near-infrared light. At this wavelength, the light is visible enough to navigate a room, read, feed a baby, and perform basic tasks, but it contains absolutely zero blue or green wavelength energy. This makes 670nm an ideal wavelength for a bedside or nursery lamp: it is functional without being disruptive to sleep biology.

For comparison, a standard "warm" LED bulb at 2700K still peaks in the blue range around 450nm. A candle flame emits primarily in the 1800 to 1900K range with very little blue, but is an impractical and unsafe light source for nurseries and bedrooms. A 670nm LED lamp provides the safety and convenience of electric light with the melatonin-preserving properties of firelight.

Red Light for Night Feeds: The Parental Sleep Connection

One of the most common applications of 670nm red light is during nighttime feeds for newborns and infants. Parents need light to breastfeed safely, prepare bottles, and change nappies, but turning on standard lights in the nursery or bedroom creates a cascade of wakefulness: melatonin production stops, the parent becomes alert, and the baby is exposed to stimulating light. The feed that should take 20 minutes leads to an hour or more of wakefulness.

By using 670nm red light during night feeds, parents maintain enough visibility to care for their baby while preserving the hormonal environment that supports returning to sleep. This is why red light lamps have become increasingly popular in nurseries across Europe and why paediatricians and sleep consultants increasingly recommend deep red night lights over standard warm white alternatives.

How to Apply This Science

The practical application is straightforward. In the 1 to 2 hours before your intended bedtime, switch from standard lighting to a 670nm red light source like Lampiero. Turn off overhead lights, put away screens, and use only the red light for reading, conversation, or quiet activities. During nighttime wake-ups, whether for bathroom trips, baby feeds, or any other reason, use only the red light. This preserves your melatonin levels and makes it significantly easier to fall back asleep.
