How can we claim that Actulite can reduce the effect of SAD?
Do we have any medical backing for our claim?
It would seem that if ordinary artificial light, with its high yellow content, gave relief from SAD, people would not get SAD. if they had lighting in their homes and workplaces. As everybody has such lighting, it obviously does not work for SAD. It therefore seems to prove that a shortage of natural light is definitely the problem.

Actulite provides light, which is technically almost identical to natural light. It is full spectrum, polarised, with no flicker of course, and with the colour temperature of natural light.

We do not have any medical proof that Actulite works
But we have many installations where, at the time, we were unaware that users suffered from SAD. However, after having Actulite fitted at their workplace, those sufferers have contacted us after the first season to tell us that they have not had any symptoms of SAD. throughout the winter period.
