Change the Light, Re-evaluate Bedtime — With Insights from Monitor Surveys | lipro's Full-Scale Launch in Japan

Premium lighting brand "lipro" will officially launch in the Japanese market in 2026. lipro proposes a new lifestyle that transforms lighting from being merely a "tool to brighten" into "light that nurtures people's circadian rhythms, eyes, and minds." This release unveils the technological background of "lipro" sunlight-replicating LED lighting and the results of a monitor survey conducted in Japan.

Why lipro Designs a "Health Infrastructure" of Light ― Technological Philosophy and Achievements

In modern society, improving the light environment is an urgent task. lipro, equipped with next-generation LEDs based on its unique sunlight replication technology, provides a foundation—a "health infrastructure"—to maintain people's physical and mental well-being.

Conventional LEDs have a sharp peak in the blue light region, which can disrupt circadian rhythms and irritate the eyes. Sunlight replication technology overturns this convention by suppressing excessive blue light peaks and reproducing a natural light wavelength balance indoors.

lipro's light suppresses excessive blue light peaks through a combination of purple LEDs and special phosphors. It complies with the "TÜV RG0" certification standard, the highest safety level, minimizing eye irritation. Additionally, it reproduces light levels almost identical to sunlight (Ra97 or higher) indoors. In the more stringent IEC tests, it boasts nearly perfect figures of Rf97 and Rg102, not only making food and skin tones appear naturally beautiful but also faithfully reproducing their texture and three-dimensionality. Furthermore, it completely suppresses imperceptible fine flickering, creating an environment that is less tiring even after prolonged use.

In the Chinese market, lipro has garnered support as a solution to the clear problem of "protecting children's eyesight." The rising rate of myopia is a serious global social issue, and the quality of lighting in learning environments is highly valued. In this context, lipro's sunlight replication technology and thorough eye-care design have been highly praised as a "health infrastructure" that protects the next generation. Building on this achievement, lipro will expand into the Japanese market with the theme of improving broader quality of life (QOL), focusing on "sleep," "circadian rhythms," and "eye health."

Meticulous Engineering Beyond the Lighting Industry

lipro has gained support as a solution for "protecting children's eyesight." The development of this innovative "health infrastructure" is led by a team of top-tier engineers with extensive experience in highly precise fields such as smartphones and automobiles. Their technical expertise in achieving both precise optical design and ease of use is challenging a new domain: making light an option for health infrastructure.

Challenges in Japan - Sleep, Circadian Rhythms, and Light Environment

In Japan, according to a survey by the Ministry of Health, Labour and Welfare (*1), approximately one in three people report being "dissatisfied with their sleep." This is not merely due to individual lifestyle habits but also to the challenge of a lack of awareness regarding the "light environment," which should be a foundation of life.

Modern lifestyles present challenges such as the normalization of smartphone and computer use at night, the impact of LED lighting on circadian rhythms, insufficient relaxation time before sleep, and reduced quality of morning awakenings.

Exposure to strong blue light at night is believed to cause the brain to mistakenly perceive it as daytime, hindering the onset of sleep. Therefore, choosing lighting that considers blue light risks (RG0) is crucial for creating an optimal light environment before bedtime. lipro aims to help address this light environment challenge by utilizing sunlight replication technology.

lipro's Proposal for "Light Rhythm Design" as a Health Infrastructure

lipro is equipped with dimming and color temperature adjustment functions that adapt to different times of day and uses. It creates a light environment that aligns with natural human rhythms. From morning to daytime, refreshing daylight white (5000K) supports activity and concentration. From evening to night, it gradually shifts to warm colors, transitioning the mind and body into relaxation mode. Before bedtime, soft warm light (3000K) provides a gentle atmosphere.

This "light rhythm design" aims to effortlessly enhance the quality of life (QOL).

Voices of Early Adopters - Signs of Change Felt by Users

Prior to its full-scale launch in Japan, lipro conducted an early adopter program for general monitors. Participants used the product in their actual living environments and freely shared their experiences of its impact.

Survey subjects: General monitors (males and females in their 20s-50s), number of responses: 17, usage period: 88.2% used for 6 days or more, main usage hours: night (6:00 PM-10:00 PM) 82.4%, before bedtime 35.3%, survey method: 5-point scale questionnaire after actual home use, products used: lipro ceiling light, bedside lamp

* The following figures represent the percentage of respondents who gave high ratings (4 or 5) on a 5-point scale questionnaire among 17 monitors and are individual impressions. Effects may vary among individuals and do not indicate clinical improvement rates.

1. Evaluation of relaxation before sleep

Q. Did you feel more relaxed before bedtime? (5-point scale) Out of 17 responses, 58.8% gave the highest rating of 5, indicating they "felt relaxed" before bedtime.

Q. Did you feel that the "quality" of your time before sleep improved? (5-point scale) Out of 17 responses, 35.3% rated 5 (highest) and 29.4% rated 4. In total, 64.7% gave a high rating to their pre-sleep time.

User comments: "Since I started using the warm light, dimmed mode before bed, I feel like I've been falling asleep earlier. When I'm working or eating, the text is easy to see, and I feel my quality of life has improved." "I've been using the warm mode before bed, and it's really good; my eldest son has become calmer when he comes into the bedroom." "My children, in particular, started falling asleep more smoothly!!"

2. Evaluation of eye comfort at night

Q. Did you feel less eye strain when looking at your smartphone at night? (5-point scale) Out of 17 responses, 41.2% rated 4 and 23.5% rated 5. In total, 64.7% gave a high rating for eye comfort at night and in the evening.

User comments: "Due to my profession, I often look at my smartphone and computer, but since switching to this lighting, it illuminates gently, and I feel my eyes are less tired than before." "I tend to get eye strain, and originally I set the brightness to be not too bright at night. But since I started using a lipro ceiling light, I've been able to finish chores in a moderately bright environment, which has made my work more efficient. Also, I feel like I can relax better afterwards and fall asleep a little earlier."

High satisfaction was confirmed particularly for use "from evening to before bedtime," indicating strong interest in optimizing the light environment at night.

Why lipro focuses on the light environment

Exposure to strong blue light at night is believed to cause the brain to mistakenly perceive it as daytime, hindering the onset of sleep. Therefore, choosing lighting that considers blue light risks (RG0) is a crucial factor in creating an optimal light environment before bedtime.

lipro addresses this light environment challenge by utilizing sunlight replication technology, supporting the creation of an environment conducive to sleep. The next-generation LEDs, based on unique sunlight replication technology, are designed with light control that aligns with human biorhythms. They suppress the "blue light peak (excessive prominence of blue light)," a common issue with conventional LEDs, and employ a flicker-free design to minimize eye strain. Furthermore, meticulous dimming and color adjustment functions for nighttime use ensure that soft, warm-toned light gently creates an atmosphere before bedtime.

Challenges of conventional LED lighting and lipro's technological advantages

Conventional LED lighting has issues such as strong blue light peaks causing significant eye irritation, poor color and texture representation, potential for disrupting circadian rhythms during nighttime use, and eye fatigue due to flicker.

In contrast, lipro's features include a full spectrum close to sunlight to support natural body rhythms, blue light risk level RG0 (TÜV certified - safest level), flicker-free design for reduced eye strain during prolonged use, and high color rendering (Ra97 or higher) for natural and beautiful color and texture reproduction.

Impact of the light environment on sleep

The human body clock is regulated by light stimuli. Exposure to strong blue light at night can easily cause the brain to mistakenly perceive it as "still daytime." lipro features dimming and color adjustment functions designed for nighttime use. By switching to soft, warm-toned light, it supports the creation of a gentle environment conducive to sleep. Furthermore, its flicker-free design reduces eye fatigue. Even when using a smartphone before bed, eye strain is minimized.
