🌙 SleepGuard — Motion-Activated Amber Night Light
(Norsk: Bevegelsesaktivert nattlys — amber lys for trygg nattkvalitet)
Soft 2000K amber. Activates when you approach, off when you don't. No blue wavelengths. Never needs charging. Set it once, forget about it.
Why Motion-Activated Amber Handles the 3am Problem
Standard night lights have two problems: they're always on (continuous low-level light exposure throughout the night) and they use white LEDs with a blue peak. Getting up for the bathroom and turning on a bright white overhead light is even worse — it reliably activates the melanopsin pathway and makes falling back to sleep significantly harder.
- Motion activation — light appears only when you're actually moving, for 30–90 seconds, then off
- 2000K amber — sits well outside the blue peak wavelength range that drives melatonin suppression
- Dusk-to-dawn sensor — won't activate during the day; only arms itself in darkness
- Adjustable — brightness level and auto-off timer set to match how long your nighttime trips take
Sleep-Protecting Benefits
😴 Melatonin Protection
2000K amber produces minimal melanopsin activation. You can navigate and return to bed with your melatonin profile essentially intact.
👶 Won't Wake Others
Localised soft glow. Enough for one person to move through a space without lighting the room broadly.
🔋 No Charging
Permanent plug-in power. Works every night without maintenance — nothing to remember or recharge.
🚶 Fall Prevention
Automatic illumination when you approach. No fumbling for switches in the dark.
🔌 Easy Installation
Plug directly into any standard outlet — no wiring, no tools, no setup beyond plugging in.
🌙 Circadian Friendly
Amber wavelengths don't carry the daytime signal that blue-white LEDs do. Your circadian system reads it as night.
Technical Features
- 2000K warm amber — soft colour temperature well outside the blue-sensitive range
- Motion sensor: 3–5m range — adjustable sensitivity
- Dusk-to-dawn sensor — arms only in darkness, off during daylight
- Adjustable brightness — low, medium, high
- Programmable auto-off — 30, 60, or 90 seconds
- Low-profile design — compact plug-in form doesn't block adjacent sockets
- Cool-touch surface — safe around children and elderly
- Under 1W power consumption — negligible running cost
- 50,000+ hour LED lifespan — effectively maintenance-free
The Science Behind 2000K Amber
Melanopsin — the photopigment in 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 2000K 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 — limiting total exposure duration — this is the practical minimum-disruption approach to nighttime navigation.
The underlying science is well-established; individual responses vary. Not a clinical device.
Where to Place It
🚽 Bathroom Corridor
The highest-traffic nighttime location. Guides you and back without requiring any light to be switched on.
🛏️ Bedroom Door
Near the exit — activates as you step out, gives you path visibility immediately.
🪜 Stairs
Fall prevention at one of the higher-risk locations for nighttime movement.
👴 Elderly Households
For older residents, automatic ambient light without switch operation is a meaningful safety upgrade.
🇳🇴 Norwegian Winters — Months of Nightly Dark Navigation
Long Nordic nights mean navigating in complete darkness multiple times a night from October to March. The SleepGuard handles it automatically — light for 30–90 seconds when needed, amber wavelengths that don't reset your melatonin, then off again. Set it once at the start of winter and forget about it.

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 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.

❓ Frequently Asked Questions
Why motion-activated amber instead of always-on?
Always-on means continuous light exposure throughout the night. Motion activation limits it to the seconds you're actually moving. Amber at 2000K produces minimal melanopsin activation — so even when the light is on, melatonin suppression is minimal.
Will this wake my sleeping partner?
The soft amber glow is localised and low-output. It illuminates your path without broadly lighting the room.
How far does the sensor detect?
3–5 metres with adjustable sensitivity. Activates within seconds of motion in the detection zone.
Can I adjust brightness and timer?
Yes. Low / medium / high brightness and 30, 60, or 90 second auto-off timer.
Does it work during daylight?
No. Dusk-to-dawn sensor only enables motion detection in darkness — no energy wasted or accidental activations during the day.
Is 2000K 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 2000K sits well outside it, producing far less melanopsin activation.
Is it safe for elderly and children?
Yes. Cool-touch surface, no sharp edges, motion-triggered so no switch operation needed in the dark. CE certified.
