Lume is research-informed, not clinically validated. The idea is simple: night light should not feel like daylight.
Most lights help you see. Lume helps the room stay usable without feeling awake.
Blue-rich light at night can make the body feel more alert and may interfere with natural melatonin timing.
Many warm-looking lamps are still made for visibility, not bedtime.
Lume uses a tuned night spectrum to support natural melatonin and keep the room in night mode.
General Science Background
Research often links blue-cyan light with nighttime alertness.
This is background context, not Lume's exact spectrum.
These studies do not clinically validate Lume.
They explain why evening light, spectrum, and blue-rich light matter at night.
Spectrum
01Study: The effects of spectral tuning of evening ambient light on melatonin suppression, alertness and sleep
This sleep lab study compared normal fluorescent light with blue-depleted LED light before bed.
Why it matters for Lume
This supports Lume's direction: less blue-rich evening light without making the room unusable.

02Study: Evening home lighting adversely impacts the circadian system and sleep
This study measured real evening home lighting and found many homes stay brighter than expected before bed.
Why it matters for Lume
Most home lights help you see.
Lume keeps the room usable without bringing daytime back.

03Study: Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults
This expert paper recommends bright days, dimmer evenings, and very low light during sleep.
Why it matters for Lume
Lume is made for the 1–2 hours before bed, when lower-stimulation light matters most.

04Study: Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor
This foundational study showed that blue wavelengths can be especially important for the body's nighttime light response.
Why it matters for Lume
This is why Lume uses a tuned sleep spectrum instead of blue-rich nighttime light.

Lume is not a medical device.
It turns evening-light science into a simple lamp for night.
Made to help reduce blue-rich light during the hours before bed.
Lume is designed for the 1–2 hours before bed, not for daytime task lighting or bright room illumination.
A physical light that helps the room enter night mode, without another bedtime task.
These diagrams are simple educational illustrations.
They are not measurement data and do not show Owlnest Lume's exact spectrum.
Warm-looking light is not automatically sleep light.
At night, spectrum and brightness shape how awake the room feels.
Lume has one job: night-tuned light for rooms that still need a little light.

Use Lume when you need a little light without turning the room back into daytime.
Sleep efficiency compares time asleep with total time in bed.
It is a common way to think about sleep quality and restfulness.
