OWLNEST
Owlnest Lume starts from a simple idea: the light you use before bed matters. Research suggests that evening light, color, timing, and brightness can affect how alert the body feels at night.
These studies are about light in general. They are not a clinical test of Owlnest Lume.
Blue-rich light at night can make the body feel more alert.
Many white or warm-looking lamps are still made mainly for visibility. They may not be the best fit for the hours before sleep.
Owlnest Lume is built around a sleep-supporting spectrum: deep amber, low-blue light designed for the hours before bed.
General Science Background
The blue-cyan range around 480-495nm is often discussed in research about nighttime alertness and light sensitivity. This is background context, not a disclosure of Owlnest Lume's exact spectrum.
These four studies do not clinically validate Owlnest Lume. They explain the lighting ideas behind it: evening light matters, home lighting can be too stimulating, lower light before sleep is recommended, and blue-rich light is important 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 bedtime, at the same room-level brightness.
Why it matters for Lume
This supports Lume's design direction: less blue-rich evening light, and a calmer spectrum for the hours before bed.

02Study: Evening home lighting adversely impacts the circadian system and sleep
This Scientific Reports study measured real evening home lighting. It found that many homes may expose people to enough light to affect the body before bed.
Why it matters for Lume
Most home lights are made to help you see. Lume is made for the pre-sleep environment.

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 light during the day, much lower light before sleep, 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 deep amber, low-blue spectrum instead of blue-rich nighttime light.

Read the studyUse the science to look at your own room. Take a quick check to see whether your evening light still feels too stimulating.
Lume is not a medical device, and your bedroom should not feel like a lab. It takes the basic science of evening light, color, timing, and lower stimulation, then turns it into a simple lamp for the hours before bed.
Made to avoid 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 for making the room feel more ready for night, 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-supporting. Color, brightness, timing, and blue-rich light all matter before sleep.
Lume has one narrow job: a sleep-supporting spectrum lamp for the hours before bed. It is not a bright task lamp or a medical device.

Use Lume as part of a calmer pre-sleep environment, before the room goes fully dark.
Sleep efficiency compares time asleep with total time in bed. It is a common way to think about sleep quality and restfulness.
Educational information only. This does not claim that Owlnest Lume changes sleep efficiency.
People often change their nighttime routine before sleep. Owlnest focuses on one part of that environment: the light your room uses before bed.

Owlnest Lume is not a medical device. It does not diagnose, treat, cure, or prevent insomnia or any sleep disorder. These studies are about light in general. They do not prove product-specific clinical results for Owlnest Lume. Individual experiences may vary.
