Experts in sun therapy

Sunwell solar simulator is a unique Swedish invention and we were first in the world with the technology to simulate real sunlight, with controlled low and safe UV content. Sunwell solar simulator replicates the sun’s entire light spectrum:

  • controlled low UVB and UVA (ultraviolet light) for e.g. a stimulation of vitamin D and other positive health effects
  • visible light up to 30,000 lux for effective light therapy
  • IR-warmt (infrared light) for comfortable heat all the way into the body

Sunwell solar simulator are therefore very effective for both light therapy and heat treatment, with many health benefits.

Sunwell products are tested by the Swedish Testing and Research Institute  (RISE), and ensure that the weighted radiation exposure is below the limits of 30 J/m2 per solar sun bath. Values for calculating the limitation of ultraviolet radiation comply with both Swedish regulations and with EU-Directive 2006/25/EC regarding minimum health and safety requirements for exposure to artificial optical radiation.

With the background from the automotive industry where the Sunwell technology has been developed for testing the heat/light resistance of various materials and systems, we have extensive experience of following strict rules and laws and can thus guarantee a well-proven, tested and quality-assured product.

In the development of the Sunwell solar simulators, we worked closely with Professor Torbjörn Laike at the Department of Environmental Psychology at Lund University. He has done research on the impact of light on humans and published several dissertations.

In 2003, a scientific study, “Artificial environmental impact on mood”, was conducted in the Sunwell solar environment with 67 people from the medical staff at Norra Älvsborgs Lasarett, in Trollhättan. The result was unequivocally positive, and the conclusion was that a short stay in the Sunwell environment relieves the negative effects of stress, burnout and SAD.

Scientists from the R&D center Fyrbodal and Vänersborg municipality have investigated the importance of using the solar rooms in 2014-2015. The results are now presented in a research report:
