The device is designed to be used nightly for 28 minutes, emitting red light to help relax the body and support natural melatonin production for improved sleep quality.


Summary: Helight, a manufacturer of photobiomodulation devices, launched Helight Sleep, a red light therapy device, in the United States last November. Using NASA-inspired technology, it emits red light at 630 nanometers to promote relaxation and natural melatonin production. Helight Sleep has won several awards and gained recognition at major events.

Key Takeaways:

  • Helight Sleep uses NASA-inspired red light therapy at 630 nanometers to aid relaxation and melatonin production.
  • The device’s development involved research with sleep disorder specialist Claude Gronfier, PhD, and medical physicist Olivier Caselles, PhD.
  • After launching in Canada and France, selling over 70,000 units, Helight Sleep has received multiple health and beauty awards and recognition at high-profile events.

Helight, a French and Canadian manufacturer specializing in photobiomodulation devices, launched its latest innovation, Helight Sleep, a red light therapy device, in the United States last November.

Helight Sleep employs a patented NASA-inspired technology that emits pure red light at a wavelength of 630 nanometers. The device operates for 14 minutes before gradually fading out over another 14 minutes, leveraging specific wavelengths of light to relax the body and stimulate natural melatonin production. This process aims to promote deeper and more restful sleep, mitigating the adverse effects of sleep deprivation and irregular sleep schedules.

Expert Collaboration and Development

The development of Helight Sleep was driven by research and collaboration with experts, including Claude Gronfier, PhD, a sleep disorder specialist, and Olivier Caselles, PhD, a medical physicist.

Photobiomodulation, the technology behind Helight Sleep, involves the metabolization of light at certain wavelengths by cells. This process promotes tissue regeneration and has anti-inflammatory and analgesic effects. Historically used in medical applications as low-level laser therapy, photobiomodulation has become more accessible through advanced LED technology. The most studied wavelength range is 630-660 nanometers, known as red light therapy.

Positive Client Feedback

Clients using Helight’s professional photobiomodulation device began noticing better sleep quality and improvement in the regulation of their internal clocks, according to the company, prompting researchers to develop a commercial sleep-enhancing device based on this principle.

Following a three-year research and development phase, 400 prototypes were produced and validated through studies using industry-standard questionnaires. The product launched in Canada and France in September 2020, with over 70,000 units sold.

Recognition and Awards

Helight Sleep has garnered recognition, winning the 2022 Top Health Technology Award, the 2023 Health.com Sleep Award, the 2024 BELLA Magazine Beauty Award, and being featured as a VIP gift at the 2024 Grammy Awards and Oscars.
