My god Michael. i have read so many articles and so many topics on light. None could ever teach me this topic as good as your video has. I am taking this knowledge to the grave. Thank you!
Tossing in another voice to the "why does the electricity video just suddenly end?" question. I was actually enjoying that and then out of no where all the sudden it just cuts off mid-
Hi. Just wanted to say that I love the "How electricity works... animated" video but it is truncated. It stops abruptly before the end. Is there a second part? If not, can you repost it complete? Thank you.
i had no idea this much went into lights. Though i should have known better. Very interesting about the color being visible tho. great videos. Please reupload the electricity video so we can see the rest of it.
i love your videos please consider going deeper into your subjects. i for one would love to watch. You provide a stright forward way of explaining things that makes following and learning extremely easy.
my uncle used to have a florescent light in his kitchen now they renovated it and removed it and now have a ceiling fan with actual kitchen ceiling lighting
Nice video. Note for the efficiencies. Old school incandescent lamps have efficiencies from 0.7% up to 2.6%, halogen incandescent lamps from 2.4% to 5.1%, not around 10%. There is good article in the Wikipedia about efficacies and efficiencies. en.wikipedia.org/wiki/Luminous_efficacy
CFLs are Compact Fluorescent Lights, essentially mini Fluorescent lights. The phase controller is integrated into the base attachment. In the tube there is mercury excited by electricity, which makes the phosphors emit visible light. CFLs are slowly to be phased out due to high concentration of mercury in our landfills from their improper disposal!

Would love to see the remainder of the electricity video. Any chance of that happening ?

Please make more! I enjoyed all the videos you made :)
Michael - you are a genius at transmitting knowledge clearly and succinctly. Thank you !

Good video!
In the city, sodium lights are my favorite...
Why does your electricity video just suddenly end?????
ophello Ha! Yes...that was frustrating.
ophello - YES! 😫
Came here just to say that
He might be a sociopath
Nice vid
Very nice video
Are there LED's now with ratings of 100, perhaps with different LED colors in a single bulb/strip?

Another pro of incandescent light bulbs is that they are infinitely dimmable
Incandescent lamp can create b emision cause tuberculosiss illness and it is antena for long-range comnunication
High pressure sodium ftw
Good video. :-)
Where is CFL lights in this list, Is it just different terminology?
CFLs are Compact Fluorescent Lights, essentially mini Fluorescent lights. The phase controller is integrated into the base attachment. In the tube there is mercury excited by electricity, which makes the phosphors emit visible light.

Prof. Ermann, which one is Halogen?
Joyce Zhang If I were to guess I'd say it is the halide metal one
Halogen lamp is newer type of incandescent lamp. Halogen lamps have higher efficiency and longer lifetime than old school incandescent lamps.
nawl Nigga. YOU.. had the easy bake oven!
I need a good light for my living room, I need it to be like old times, lounge light, jazz light u know, what would that be?
