Welding is indeed a bit bright. It’s the only thing I’ve ever seen through my eyelids.
It's the last thing I saw
Scummo, is that you?
The best part is the video shows him doing it like 3 times haha

asdfasfasfasfasI know that would've been terrifying in the moment, but God that's a funny mental image

asdfasfasfasfasWatts is what sets fires, though. It's literally the "amount of energy delivered to the surrounding area per second"
1-2 kW is pretty typical for a single cooktop/hot plate or small space heater, so at least that same amount of energy put out by of those is going to be coming from that light. Some of that energy is in the form of the light, but at least a fair amount of it is heat, and "several thousand" could be a lot more than 1-2.
Iirc max efficiency of any light is around 600 lumens per watt, so a theoretically perfect light source that's 7000 watts would hit 4 or 5 million lumens. Probably more like 3 million for real, physical lights that are only 80% or so efficient.
That seems like a lot more than you need unless you're simulating the sun or something for a shot. So probably not an LED
I can weld with my eyes shut!
That is VERY HARD to do!
But it’s bad for my hat and makes my eyebrows get red hot.
so…
welding with my eyes shut I don’t do an awful lot.
