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.

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

> I love the idea that we believe…

Strong reaction? I don’t know anyone who would believe that.

I don’t think we need to replicate everything about nature to incorporate what we know about nature, ourselves, and the practical details of our lives.

I have bright LEDs around my ceilings, hidden by cove molding, turning the whole ceiling into soft but bright reflected daylight.

It doesn’t need to replicate a real summer day outside to improve my mood and avoid depression in winter. Much better than ordinary indoor lighting.

Most people take some kind of supplement or medication that doesn’t replicate pre-technological natural conditions but provide benefits.

Improving our respective conditions, in the artificial world we live in, can involve quirky adaptations for each of us.
