What our customers say
Marion Kapellas
Spa Manager at AMAN at the Connaught
United Kingdom
“Most of our guests think we have windows, and it is a natural light. It creates a very nice environment and boosts you for your workout. The space also looks much bigger.”
Doctor Alex Lee
Home Owner & Anesthesiologist
United States of America
“I'm an anesthesiologist, and I'm in a big windowless room for 12 hours a day sometimes. I think about it all the time, I wish I had one of these in the operating room. It would make things so much easier and much more pleasant. It would be great for patients getting chemotherapy and children waiting for their MRI and radiation oncology. These could significantly help improve the environment and the outcomes.”

“As soon as the Virtual Sun was fitted, I felt instant relief and a surge of creative energy.”
