Read late. Sleep well. — Leselys uten blått lys
Standard reading lights are working against your sleep. The same light letting you finish one more chapter is telling your brain it's noon. This clip-on peaks at 630nm red — sitting completely outside the wavelengths that suppress melatonin. Clip it to your book, your e-reader, or stand it on the nightstand. Read as late as you want without paying for it the next morning.
💡 Why your current reading light is sabotaging your søvn
Regular reading lights — including built-in e-reader backlights — emit blue wavelengths between 400–500nm. Even at low brightness, these signals tell your sirkadisk system it's still daytime. The research is consistent:
- Delayed sleep onset — melatonin suppressed, often by an hour or more, from a single evening reading session
- Up to 85% melatonin reduction — even brief blue light exposure makes a measurable difference to your søvnkvalitet
- Poorer sleep architecture — less deep sleep through the night, even if you fall asleep at the usual time
- Partner disruption — traditional bedside reading lights affect whoever is sleeping beside you
This light peaks at 630nm — a wavelength your sirkadisk system doesn't register as a wake signal. Melatonin builds uninterrupted. For a deeper look at why the light environment matters so much, Dominic's guide to indoor lighting in Norway is worth reading before you buy.
Two variants — both 100% blue-light-free
Both protect your melatonin completely. The choice is about colour tone and how much brightness you need.
Both are melatonin-safe. The choice is purely about colour preference.

Zero blue light — melatonin builds uninterrupted right to the moment you close the book
Safe for barn

Full charge in 1 hour
USB-C fast charge — plug in during the day, ready by evening
Three brightness levels
Low, medium, high — set it to match your room, from total darkness to low ambient light
Clips or stands
Strong clip handles books and e-readers up to 5cm thick, or stands independently as a nattbord light

🇳🇴 Why this matters more during mørketid
Norwegian vintere mean more waking hours under artificial light than almost anywhere else in Europe. When daylight disappears in November, most Norwegians read more — which means more evening light exposure. If that light contains blue wavelengths, it compounds the sirkadisk disruption that limited winter daylight already creates. A blått lys-fri leselys is one of the simplest fixes available. For a deeper look at why the light environment matters so much during the mørketid, Dominic's guide to indoor lighting in Norway covers the full picture.
This leselys is part of a complete søvnvennlig light environment. It pairs naturally with the Family Sleep Pack which includes matching amber and red bulbs, a motion sensor, and a second clip-on for shared spaces. Or explore the full circadian lighting collection.

From Dominic
This is the product I recommend first to anyone who reads in bed. The underlying problem — blue light from your leselys telling your brain it's daytime while you're trying to wind down — is so simple to fix that it surprises people. I reach for a red light every evening. Not because it's a major lifestyle change, but because it requires almost no effort and the difference to how quickly I fall asleep is real and consistent. I've had customers in Norway tell me this was the smallest purchase they made from us and one of the most noticeable in everyday terms. Start here if you haven't already.

❓ Vanlige spørsmål / Common questions
What is the difference between the two variants?
Both are 100% blue-light-free and melatonin-safe. Red-only (630nm, 7 LEDs) blocks everything from 380–550nm for maximum circadian protection. Red + amber (630nm + 1200K, 8 LEDs) blocks 380–500nm and gives a warmer, slightly brighter output — better for longer sessions or small print. The choice is purely about tone preference.
Hva er leselys uten blått lys og hvorfor trenger jeg det?
A leselys uten blått lys emits only red or amber wavelengths — free of the blue light (400–500nm) that suppresses melatonin. Standard reading lights contain blue wavelengths that tell your brain it's daytime, even late at night. A blått lys-fri leselys lets your melatonin build naturally right up to the moment you stop reading.
How long does the battery last?
Up to 40 hours on the lowest setting, 10 hours on the highest. Most people charge it once a week or less. USB-C fast charge takes 1 hour for a full charge.
Er det trygt å bruke rundt barn?
Yes. Flicker-free 630nm red light doesn't affect melatonin and is safe for children's rooms. Children are actually more sensitive to blue light than adults, so the benefit is even greater for them. It's suited to bedtime stories without the activated response that standard lights cause.
Does it work on a Kindle or e-reader?
Yes. The clip handles surfaces up to 5cm and grips e-readers, paperbacks, and hardcovers without damaging the binding. It also stands independently if you prefer that.
Vil dette faktisk forbedre søvnen min?
Blue light in the evening suppresses melatonin and delays sleep onset — this is consistently demonstrated in research. Removing blue light from your evening reading eliminates one of the most common sources of sirkadisk disruption. Most people notice they feel sleepier at a more natural time within the first few nights.
Is it suitable for travel?
Yes — lightweight and compact, it fits in any carry-on. Many customers use it specifically to keep their søvnrutine intact in hotel rooms and on long-haul flights.

Les sent. Sov godt. — Read late. Sleep well.
You shouldn't have to choose between the book and the sleep. This clip-on leselys gives you both — comfortable illumination that protects your døgnrytme right up to the moment you turn it off.
Note: Eliminating blue light is one important part of good søvnhygiene. For best results, combine this light with consistent sleep timing and reducing screen use in the hour before bed. Individual responses to light vary.
