My most stereotypical special interest (in that it's something really random that you might assume there's not a lot of depth to) is artificial lighting technology.
But I have a lot of stuff I could infodump about: computers, video games, TTRPGs, world building, neurology, etc.
I have a question for you that I've not been able to get answer to by normal googling or asking the GPTs.
I need to focus light from cinema projectors using camera lenses. As you might be aware, projectors may use lamp or LED as their primary light source. The former used more wattage for producing same lumens of light.
My question is: if I choose two projectors of each type that give out same lumens of light and I focus all of it with my lens, will one of them heat up my lens more than the other? I'm other words I'm just talking about the heat perception of light of equal intensity from the two sources and not how much heat is generated in creating them, if that makes any sense.
Thanks!
Have you seen the technology connections videos on lighting? The one about the Balafire is interesting, and he also recently discovered some excellent Christmas lights.
Could you tell me some cool stuff about artificial lighting technologies? That sounds interesting!
