Lack of sunlight during the day is worse than electric lighting at night

You can't do a 'lumen' lamp. The IR rays are what help. Anecdotally it felt good to cover my hands with the old lamps, and the cfls and LED lights never "felt" good.

Be careful of eye damage. Cataracts form from certain frequencies of blue light, and IR can damage your retina.

(There was an article about some guy with an IR heater on his desk, which was partially faulty, and emitted too much IR in a certain frequency, and damaged his eyes)

I got a "Happy Light" for my desk that is 10k Lumens. could that be damaging my eyes?

Link to that particular product please? I'll see if I can suss out the spectral emissions. In general, with lights that bright you probably don't want to be looking directly into them anyway, and you may want to add a diffusor if it isn't built in already.

My understanding is that typically it isn't an issue, but the hearer malfunctioned, and it was on his desk, and so he was kind of staring at it all day.

I'd take care. Don't stare into the light, for starters.

Thanks for the article. Looks like he got his eyesight back so it wasn't permanent.
