It's called a Soleira sun simulator system. Briton House, a privately-owned retirement home in Toronto, has one.
There, residents can escape on a tropical break without ever leaving home.
The room is equipped with a simulated beach, with sand, the sound of surf, and plenty of warmth and sunshine thanks to a light system that simulates the summer sun
Eric Pflanzer runs the Canadian office of the Swedish-based Soleira Sun.
He says the system's computer and light system reproduce the sun's full-light spectrum, but it also reduces the harmful effects of UV rays.
Theoretically, the lights allow the skin to produce vitamin D, but without the damaging effects of tanning.

Their system unfortunately has very little UV: about 1/3 that of the noon-time sun in Canada
They did not indicate how much UVA vs UVB

Recall that UVA produces tanning, UVB produces vitamin D.
