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 :

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...

I also looked into this and ended up being successful when searching for photography lights and corn cob LEDs. Corn cob bulbs at 40-60 Watts each are cheap (~20USD in the UK), provide ~4K lumens each, and 2-3 are bright enough to get to daylight levels. Would highly recommend if you want to see whether it makes any difference, and/or which colors temp works best.
