The poor bulb 😢

😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂

guess not

hello anybody here

❤❤❤❤❤

Broken bulb is out

Good

🎉🎉

House

Good

Ha😂😂😂😂😂😂😂😂😂😂😂

Is you

How did you hook it up?

A light bulb

I know

The cover is far too big for Liam to guess the bulb correctly. A smaller cover would allow the bulb to cast some shadows onto it

Is this a stationary boat?

Thanks

The two fluorescent wraparound lights you showed at 2:02 and 2:17 have magnetic ballasts in them! You can tell because of the banding on the video, caused by the very slight difference between the refresh rate of the camera and the flicker frequency of the fluorescent lamps. High-frequency electronic ballasts do not cause the banding because they drive the lamps at tens of thousands of hertz, unlike the 60 Hz of old school magnetic ballasts, and this frequency is so fast that the phosphor does not have a chance to glow down in between pulses, making it appear as perfectly steady light even to cameras. Additionally, you can tell that the lamps in the fixtures use halophosphate phosphors, as the bands are yellow. Dark green or black bands would indicate deluxe halophosphate phosphors, bright green would indicate tri-phosphors, and yellow and green bands would indicate a blend of halophosphate and tri-phosphors. Halophosphate phosphors are the old-school type, they use two calcium halophosphate materials that emit orange-yellow and blue light, and varying the proportions of these components changes the color temperature. Because they emit mainly yellow and blue light, they do not cover the light spectrum very well, and the CRI of these lamps is relatively poor (only 62 for cool white halophosphate fluorescents). Deluxe halophosphate phosphors add an additional red component on top of the standard halophosphate coating, which boosts the CRI to around 88. However, these lamps are only around 75% as bright as the standard halophosphate lamps. Tri-phosphors use red, green, and blue phosphors to produce white light, similar to how a TV uses red, green, and blue pixels. Since your eyes are most sensitive to red, green, and blue light, these lamps are very efficient and have a very good CRI, around 85 for pure tri-phosphor lamps. Again, varying the proportions of the three components can produce various color temperatures. Sometimes, tri-phosphors are mixed with halophosphates to create “in-between” lamps that have a CRI of around 75.

The lights at the beginning are metal halide. The lights at the end are high-pressure sodium.

That’s pretty weird the way they set these up. I have heard of that sort of thing being done with 3-lamp and 4-lamp fixtures to provide a bi- or tri-level “dimming” effect, but I have never seen or heard of it being done with 2-lamp fixtures or strip light fixtures in general. This setup would require two 1-lamp ballasts in each fixture too, instead of one 2-lamp, which would be pretty strange. Or maybe they are doing that thing where one (or in this case, two, I guess) ballasts are shared across several fixtures. So in this case, it could be one 2-lamp ballast driving one lamp each in a pair of fixtures, and then another driving the remaining two lamps in the pair. Or the same thing done with 3-lamp ballasts across three fixtures, or 4-lamp ballasts across four fixtures. Either way, very interesting. Also, they seem to do a pretty good job at maintaining these, and still use fluorescent lamps in 2024. Nice.

On light come up

Get high powered CFLs that fits those sockets.

6:13

2:52 it takes a lot of turns befcause it isnt a 3 way bulb

What types of light bulbs are there in the vanity lights? :)

Fantastic video. Some of your fixtures don't look too common in the U.S., based on many other "switches in my house" videos on TH-cam!

Needs a new bulb

Cool...is it new?

You need more likes😢

I like it❤

those "curly bulbs" are actually spiral cfls (just in case you didnt know)

😊😅😊😊😊

Luzes cheio de insetos 🪰🦟💡😉

Isn't that a 5w? Because I want one

new battery

Hello

Maioria as lâmpadas 💡💡💡💡💡💡💡💡💡💡💡💡💡

Oh man, if only there was some way to move that rainy glass out off the way

The bi-frost thor has arrived. lol

Never get used to it

God bless us all you both

Next time if there is a two way switch you need to say second switch😊
