Could indoor or outdoor artificial sun products soon be 'better than sun' (for humans)?

e.g. has the hormone regulation & vit d synthesis benefits, without the skin damage?

Because it seems like we're getting there: https://www.sciencedaily.com/releases/2017/09/170913193101.h...

A fun modification would be to add a mask directly in front of the LED to change its shape, for instance to mimic the weird crescent shadow effect that many of us saw during the last solar eclipse.

Some other fun things to do with it would be to point it through some plants in front of a fan to get the filtered-light-through-leaves effect, or to shine it onto moving water.

If you're too lazy to build something like this out but like the idea I highly recommend bright LED lighting for the day (explained here: https://www.benkuhn.net/lux/). I bought two ~7000 lumens LED corn bulbs and have noticed a huge shift in energy levels from having a brightly-lit room in dark PNW days. I put together a bunch of resources when I was researching buying some here: https://www.notion.so/vimota/LED-World-fce39f79710b42708b92a...

Seconding this, although I only bought one giant 14k lumen corn cob, since I didn't have a good spot to put the second. Anecdotally, they've been great at staving off my usual post-lunch slump. Right around the same time as I got it, though, I started waking up much earlier naturally, without an alarm clock (shifting from ~9AM natural wake up to more like ~6AM). I'm careful about turning the corncob off no later than 6PM, and the earlier wake up time might be unrelated, but I was wondering if others had experienced a similar phenomenon with extended, consistent exposure to super bright lights during the day.

Interestingly I posted this 2 days ago but it dropped into the ether.

Ever since I seen it I've become convinced something similar will be part of a future garden office I'm planning. With a IR panel heater to add the warming effect. I was also wondering about whether UVB could be incorporated by but frankly I'd be too chicken to mess with that.

Sounds very interesting - i am currently in Europe and can see that the price is about 350 usd, and you can get versions from 3000 (warm) to 6400 kelvin (sunlight?).

What kelvin did you choose, and how large is your room? Did you put something in front of the lamp to diffuse?

Looking forward to get out of the lockdown slump! :)

I was looking into this last year, but couldn't really find anything similar here in Sweden (or anywhere in the EU). I wonder if there are some regulation here banning ultra high lumen bulbs? The closest match have been on semi-sketchy sites, where they've been ≈ 300 euro for 10k lumen...

How expensive are they in the US?

Also in Sweden - there is this Danish shop :

https://www.ledproff.dk/produkter/11907-kraftige-led-paerer-...

Trustpilot doesn't raise any major red flags, but i don't know the shop, it has "e-maerket" though which is official certification.

13.5K for about 400 usd. So it it must at least be legal in EU? They also have 14.8K if you go up 1 level.

Wait a minute, they also have a swedish shop:

Ah, nice. I recognise the brand of the lamp from earlier research. I read this post just now https://meaningness.com/metablog/sad-light-led-lux, where he's using ≈ car lights. That got me thinking about construction lights, they are apparently much cheaper. But not sure about the Color Rendering Index. Here [1] we have 8000 for 600 sek, but not in as a nice design maybe...
