SleepGuard - Motion-Activated Amber Night Light for Sleep
Bevegelsesaktivert søvnvennlig nattlys uten blått lys - for trygg nattkvalitet
Soft 1800K amber. Activates when you move, off when you don't. No blue wavelengths. Plug in once, works every night without maintenance.
Why this amber sensor night light handles the 3am problem
Most people fix their evening light environment with circadian bulbs and blue light blocking glasses, then undo all of it at 3am when they get up for the bathroom and switch on a bright white overhead light. That single exposure is often enough to suppress melatonin, raise alertness and make falling back to sleep noticeably harder.
The SleepGuard is the fix for that last gap. It's a motion-activated amber nattlys (night light) that activates when you approach, stays on for 30 to 90 seconds, then goes off. The 1800K amber wavelength sits outside the melanopsin activation range, so even when the light is on, your sleep chemistry stays roughly where it should be.
- Motion activation - light appears only when you are moving, for 30 to 90 seconds, then off automatically
- 1800K amber - sits outside the blue wavelength range that drives melatonin suppression
- Dusk-to-dawn sensor - only arms itself in darkness, won't activate during the day
- Adjustable - brightness and auto-off timer match your actual nighttime routine
What it protects you from
Melatonin protection
1800K amber produces minimal melanopsin activation. You can navigate and return to bed with your melatonin profile essentially intact - unlike flipping on a standard white light.
Won't wake others
Localised soft glow. Enough for one person to move through a space without broadly lighting the room or waking a partner or child.
No charging or batteries
Permanent plug-in power. Works every night without maintenance - nothing to remember or recharge at exactly the moment you need it.
Safer nighttime movement
Automatic illumination when you approach. No fumbling for switches, no navigating obstacles in complete darkness.
Easy installation
Plug directly into any standard outlet. No wiring, no tools, no setup beyond plugging in and choosing your brightness and timer settings.
Circadian friendly
Amber wavelengths don't carry the daylight signal that blue-white LEDs do. Your circadian system reads 1800K as night, not as a signal to start waking up.
Who needs this
New parents and night feeds
The SleepGuard activates when you enter the room, gives you enough amber light to see safely during a feed, then turns off. No switch to find in the dark, no blue light blast that makes returning to sleep harder for you or the baby.
Anyone managing sleep quality
If you've sorted your evening light environment but still struggle after nighttime waking, this is usually the missing piece. The one exposure event you can't fix with glasses or bulbs alone.
Elderly and mobility-limited households
Automatic amber light with no switch to operate is a practical safety upgrade for older residents. Reduces fall risk without requiring any action in the dark. CE certified, cool-touch surface, child and elderly safe.
Shift workers and irregular schedules
When your sleep windows don't align with normal daylight hours, protecting those windows matters even more. The amber sensor night light makes nighttime movement possible without disrupting whatever sleep you can get.

The science behind 1800K amber
Melanopsin, the photopigment in intrinsically photosensitive retinal ganglion cells (ipRGCs) responsible for circadian melatonin regulation, has peak sensitivity around 480nm (blue-cyan). Standard white and cool-white LEDs emit strongly in this range, which is why even brief nighttime blue light exposure is associated in research with melatonin suppression and delayed sleep recovery.
Amber at 1800K has a spectral distribution centred well into the warm orange-red range. Melanopsin activation at these wavelengths is substantially lower than at blue-enriched wavelengths. Combined with motion activation, which limits total exposure duration to seconds, this is the practical minimum-disruption approach to nighttime navigation. The full underlying research is covered on my photobiomodulation and light research page.
The underlying science is well-established; individual responses vary. Not a clinical device.
Where to place it
Bathroom corridor
The most common nighttime trip. Guides you there and back without requiring any light switch to be found or operated in the dark.
Bedroom door outlet
Near the exit point, activates as you step out, gives you path visibility immediately from the moment you leave the bed area.
Stairs
One of the higher-risk locations for nighttime movement. Automatic amber illumination without any switch operation.
Baby's room - night feeds
Activates when you enter for a feed, stays on as long as you need it, then goes off. Amber wavelength keeps both parent and baby in sleep mode.

From Dominic
The SleepGuard is the easiest possible intervention. Plug it in, walk away. People who've done all the right things with their evening light environment and still struggle to fall back to sleep after getting up at night often find this closes the gap. It costs almost nothing to run and handles the one exposure event you can't control with glasses or bulbs alone. If you're building a full circadian setup, I'd add this alongside the circadian lighting collection.

Frequently asked questions
What is the best night light for sleep that won't disrupt melatonin?
A melatonin-safe night light uses amber or red wavelengths (1800K or lower) rather than white or blue-white LEDs. The SleepGuard uses 1800K amber, which sits outside the melanopsin activation range concentrated around 480nm blue-cyan. Motion activation then limits total exposure to seconds at a time - so even the brief light on period causes minimal disruption to your sleep chemistry.
Is a motion-activated amber night light better than always-on?
Yes. Always-on night lights produce continuous low-level light exposure throughout the night. Even amber light has a cumulative effect when present for hours. Motion activation limits exposure to seconds at a time, so your circadian system registers darkness for most of the night. The combination of amber wavelength and motion activation is the minimum-disruption approach.
Will this wake my sleeping partner?
The soft amber glow is localised and low-output. It illuminates your path without broadly lighting the room or disrupting a sleeping partner.
Is it good for night feeds and new parents?
Genuinely useful here. It activates when you enter the room, gives you enough amber light to see during the feed, then turns off. The 1800K amber wavelength won't trigger the melanopsin pathway in you or the baby, which makes returning to sleep much easier than if you'd switched on a standard white light.
How far does the sensor detect?
3 to 5 metres with adjustable sensitivity. Activates within seconds of motion in the detection zone.
Can I adjust brightness and timer?
Yes. Low, medium and high brightness settings, and a programmable auto-off timer of 30, 60 or 90 seconds.
Does it work during daylight?
No. The dusk-to-dawn sensor only enables motion detection in darkness. No energy wasted, no accidental activations during the day.
Is 1800K amber really better than white light at night?
Yes. Melanopsin activation, the mechanism behind nighttime melatonin suppression, peaks around 480nm (blue-cyan). White LEDs emit strongly in this range. Amber at 1800K sits well outside it, producing far less melanopsin activation. The science here is well-established across multiple independent studies.
Hva er det beste nattlyset for søvn uten å forstyrre melatonin?
Et melatonin-vennlig nattlys bruker amber eller røde bølgelengder (1800K eller lavere) i stedet for hvite LED-er. SleepGuard bruker 1800K amber, som ligger utenfor melanopsin-aktiveringsområdet rundt 480nm blå-cyan. Bevegelsesaktivering begrenser deretter total eksponering til noen sekunder om gangen - minimalt forstyrrende for søvnkjemien din.
Hjelper amber nattlys under mørketid i Norge?
Ja. Under norsk mørketid fra oktober til mars navigerer mange i total morke flere ganger per natt. SleepGuard gir deg amberlys i 30 til 90 sekunder nar du trenger det, uten a tilbakestille melatoninprofilen din. Det er det beste nattlyset for søvn i norske vintermaner - sett det inn en gang og glem det.
Er det trygt for barn og eldre?
Ja. Kul berøringsflate, ingen skarpe kanter, stikkkontakt uten batterier. Bevegelsesutloser betyr at ingen trenger a betjene en bryter i morket. CE-sertifisert og barnesikker.
