I love the idea that we believe that we can replicate all of the natural processes involved in getting a tan, and to such a precision that we can then speed up the process 10 fold, and that we can fit it all into a single unit that can be wheeled in and out of the room.

Unless of course our calculations are a bit off, then we accidentally created a bed version of the wrong chalice from raiders of the lost ark, but I think it's fine.

Replicate the natural processes? It's literally just UV light.

UV comes in an huge variety of strengths outdoors.

There are no calculations to be a "bit off". It's just strong UV. You're making it sound a lot more complicated than it is.

Sun also emits infrared which seems to cause positive effects counteracting some of the UV related problems.

		Some cell and animal studies show that there is a slight possible effect. It hasn't been shown in humans, and even in extrapolation from animals, the protective benefit does not seem particularly significant.

Yeah. There are so many variables already. From angle to time of year to skin pigment to duration
