Description
Recreating natural daylight
Vitamin L emits an evenly distributed, stable 4000 K spectrum that replicates morning daylight, a key factor regulating circadian rhythms. Bright 10,000 lux light from a distance of 20 cm helps reduce morning drowsiness, activate alertness, improve mood and emotional well-being, and maintain energy levels throughout the day. The light does not emit UV rays, so it is safe for daily use.
Scientifically based light therapy
Bright light in the morning suppresses melatonin production and sends the body a signal to start the day. Studies confirm that 10,000 lux light therapy can help:
- regulate sleep-wake rhythm
- reduce symptoms of seasonal fatigue
- improve concentration and productivity
- to neutralize the energy drop typical of the winter period
Vitamin L is a simple and effective way to compensate for the lack of natural light.
Optimized for everyday use
This model is designed to be as simple and convenient as possible:
- fixed brightness and color temperature
- easy operation with a single on/off button
- wavy textured diffuser for soft light distribution
- slim, easy-to-carry body
Vitamin L becomes a natural part of your morning routine – just turn it on and get going, without any complicated settings.
Portrait and landscape orientation
The removable stand allows Vitamin L to be used vertically , for a narrower position that’s perfect for a desk, or horizontally , for a wider view that’s more like a window with natural light. In both positions, the device remains stable and ergonomic.
Compact and easy to transport
Slim, lightweight and portable, Vitamin L is suitable for everyday use at home, at work, on trips, for students, working in libraries or auditoriums. Thanks to its minimalist design, the device easily blends into any interior environment.
Design and security
Vitamin L is a robust, medical-grade device that does not emit UV rays and is a Class II medical device certified for the EU and UK markets.
