The Night-Feed Light That Lets the Whole House Sleep

A mother carrying her sleeping newborn and a glowing LYSA red lamp through a dark nursery

Swap the big overhead light and your phone screen for a dim red glow. A 670nm red lamp gives you just enough light to see your baby through feeds and nappy changes, without switching on the “wide awake” response in either of you. Red is the usual choice for night-time because it feels far calmer than bright white light.

Why the Big Light Makes Night Feeds So Much Harder

Your baby stirs at 2am and you need to see. So you hit the light switch or grab your phone. Both flood you and your baby with blue-heavy light, and both brains get the same message: it’s morning.

Now you’re wide awake. So is the baby. And the next hour and a half is gone.

Ordinary LED bulbs, even the “warm white” kind, still put out roughly a third of their light as blue wavelengths. A phone in night mode, held close to your face, still sends a strong wake-up signal. Both hold back melatonin, the hormone that keeps you and your baby drowsy.

It’s why parents who’ve been through it call those first months “the newborn trenches.” It isn’t only how often you’re up. It’s the light you switch on every time you’re up that wrecks the rest of the night.

What Changes When the Light Is Red

Deep red light at 670nm doesn’t set off the melanopsin receptors in your eyes. Melatonin keeps flowing. You can see the baby, change the nappy, make up the bottle and feed, all without tipping your body into “alert” mode.

The feed still happens. The nappy still gets changed. But how long it takes everyone to drift off again gets much shorter.

With the overhead light or a phone

  • Bright light wakes the baby fully
  • You end up alert and wired
  • Melatonin held back for 60–90 min
  • Baby fusses and won’t settle
  • You scroll while you wait
  • Everyone awake for an hour or more

With a 670nm red lamp

  • Just enough light to see and do it
  • Baby stays drowsy
  • The room feels softer and calmer
  • Change, feed, back down
  • No phone needed
  • Partner and siblings sleep on
  • Lots of parents find settling again easier

How Parents Use It

On the changing table

Turned right down. Stands flat and steady. Enough light for the nappy, the wipes and your baby’s face.

For feeds

On the bedside table or next to the nursing chair. Pick the brightness that works without lighting up the whole room.

From room to room

200g, lighter than your phone. An 8+ hour battery, so nothing needs plugging in at night.

With the timer

Nod off mid-feed? Set the 30-minute timer and it switches itself off.

“Couldn’t I just use a normal lamp turned down low?”

Even dimmed, a warm white LED still gives off blue and green wavelengths that hold back melatonin. A 670nm LED gives off deep red only, well away from the wavelengths that tell your body to wake up.

The Science, Without the Jargon

670nm is a particular wavelength that sits outside the range your brain uses to decide “it’s daytime.” Studies published in the Journal of Athletic Training, along with work from Harvard and the China Institute of Sport Science, found that red light at this wavelength goes along with your melatonin production instead of holding it back. Dr Andrew Huberman suggests dim, red-spectrum light for evenings and night-time.

LYSA isn’t a therapy panel and it isn’t a medical device. It’s a portable bedside lamp with 670nm LEDs, made for everyday use: night feeds, nappy changes, bathroom trips and winding down before bed.

Common Questions

Is red light safe for newborns?

Red light doesn’t hold back melatonin and is widely used in nurseries. LYSA’s brightness slider lets you turn it right down. Always follow your paediatrician’s advice.

Will my baby be scared of the red light?

Most parents tell us the opposite: babies find the soft red glow soothing.

How bright is LYSA on its lowest setting?

Bright enough to see the baby, the nappy and the bottle. Dim enough that your baby stays drowsy.

Does it have to be plugged in?

No. It recharges over USB-C and runs 8+ hours on a charge. Charge it in the day, use it cordless all night.

What if it doesn’t work for us?

You’re covered by the 30-Night Sleep Promise. Use it every evening, and if you notice no difference you get a full refund.

My new evening routine

Since this lamp arrived my phone goes down at nine. Red light, a book, sleep. That's my routine now.
MMikkel S.Verified

★★★★★

Really pleased

The baby doesn't fully wake up any more and I get back to sleep much faster. Wish I'd had it from day one.
EEmilia L.Verified

★★★★★

It genuinely works

With only a few hours of daylight here in winter, this lamp has been a lifesaver. My sleep is noticeably better.
AAgnieszka W.Verified

A nice surprise

I ordered from Poland without expecting much, but this lamp surprised me. After two weeks I'm sleeping better and more deeply. The build quality is very good too.

Perfect for the nursery

Sits on the changing table every night. Enough light to see what I'm doing and my daughter barely stirs.
TTom R.Verified

Partner no longer wakes

I do the late bottle. Before, the bedside light woke my wife every time. Now she sleeps straight through it.
JJulia M.Verified

★★★★★

Small, light, lasts all night
