Read late. Sleep well. - Leselys uten blatt lys
Standard reading lights are working against your sleep. The same light letting you finish one more chapter is telling your brain it is 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 sovn
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 is 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 sovnkvalitet
- 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 does not 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.

Why this matters more during morketid
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 blatt lys-fri leselys is one of the simplest fixes available. For a deeper look at why the light environment matters so much during morketid, Dominic's guide to indoor lighting in Norway covers the full picture.
This leselys is part of a complete sovnvennlig 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 is daytime while you are trying to wind down - is so simple to fix that it surprises people. I reach for a red light every evening. Not because it is 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 have 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 have not already.

Vanlige sporsmal / Common questions
What is the best reading light for sleep in Norway?
The best leselys for sleep emits pure 630nm red with zero blue or green (380-550nm blocked). Melatonin builds uninterrupted while you read - unlike all standard reading lights and e-reader backlights. The red-only variant offers maximum circadian protection; red-amber gives a warmer tone for extended sessions. 40-hour battery on low, USB-C fast charge. Ships from Drammen with no import fees.
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 blatt lys og hvorfor trenger jeg det?
Et leselys uten blatt lys sender kun rode eller amber bolgelengder - fritt for blatt lys (400-500nm) som ville undertrykt melatonin. Standard leselys inneholder blatt lys som forteller hjernen din at det er dag, selv sent pa kvelden. Et blafritt leselys lar melatoninet bygge seg opp naturlig helt til du lukker boka.
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 a bruke rundt barn?
Yes. Flicker-free 630nm red light does not 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. 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 sovnen 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 sovnrutine intact in hotel rooms and on long-haul flights.

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