Stop Losing 90 Minutes of Sleep to Every Bathroom Trip
Use a portable red light instead of the bathroom light. Turning on a standard light at 3am suppresses your melatonin for up to 90 minutes. A 670nm red lamp lets you see clearly without triggering the hormonal wake-up response — you fall back asleep in minutes instead of hours.

You fall asleep fine. Then your bladder wakes you at 2 or 3am. You get up, flip on the bathroom light, and within 30 seconds your brain decides it is morning. Now you are lying in bed, wide awake, staring at the ceiling for 60 to 90 minutes.
The problem is not your bladder. The problem is the light.
Standard bathroom lights are bright, blue-rich LEDs. Even a few seconds of exposure activates the melanopsin receptors in your eyes and suppresses melatonin. Your brain interprets this as: the sun is up, time to be alert.
This is not an insomnia problem. It is a light-exposure problem with a simple fix.
Bathroom Light vs Red Light
- Bright white/blue LEDs hit your eyes
- Melatonin suppressed for 60–90 min
- You feel alert and wired
- Lie awake thinking about tomorrow
- Reach for your phone
- Partner wakes up too
- Finally drift off 90 minutes later
- Deep red light does not trigger wakefulness
- The light feels less harsh and less stimulating
- You see clearly but stay drowsy
- Back in bed, still sleepy
- No phone needed
- Partner stays asleep
- Asleep again within minutes
How It Works in Practice
Tap it on. Touch control works in the dark — no fumbling.
200g. Lighter than a glass of water. Bathroom, hallway, anywhere.
Even on a low setting, bright enough to navigate safely.
The light feels less harsh and less stimulating No hallway light blast. It can feel easier to settle back down afterwards
The whole trip takes the same time it always did. The difference is what happens after. Instead of lying awake for an hour, you are asleep in minutes.
A red-tinted bulb may look red but still emits blue and green wavelengths. Most motion-sensor lights use warm white LEDs — same problem. A 670nm LED emits only deep red, designed for softer night-time use
"I use it when I get up in the middle of the night. It became my torch. Helps not to have blue light interfere with my melatonin."
"Great for late night bathroom trips. It will not have you squinting!"
"Purchased it for the bathroom so I do not have to turn on the main light for late night visits. Works a dream."
"I can see clearly, and more importantly I can get back to sleep with no issues."
Use it every evening for 30 nights. Full refund if no difference. No questions.

Why 670nm Works for Night Wake-ups
670nm is a deep red wavelength that sits outside the range detected by melanopsin cells, the light-sensitive receptors that tell your brain whether it is day or night. Research from Harvard and the China Institute of Sport Science confirmed that light at this wavelength does not suppress melatonin. Dr Andrew Huberman recommends dim red-spectrum light for any nighttime activity.

Common Questions
Why does the bathroom light wake me up so much?
Standard bathroom lights use bright, blue-rich LEDs. Even a few seconds activates melanopsin receptors, suppressing melatonin for 60 to 90 minutes.
Can I use my phone as a torch?
Your phone still emits blue light, even with night mode. It also introduces the temptation to scroll.
Is the red light bright enough?
Yes. Even on a medium setting, Lampiero provides enough light to navigate safely.
I get up 2 to 3 times per night.
Since 670nm does not suppress melatonin, each trip stays low-impact. The 8+ hour battery is ready.
Will the red light wake my partner?
No. On a low setting, most partners sleep through it.
