im about to noclip out of reality into the backrooms

Natural lighting is beautiful. I wish there was technology that could closely mimic it.

Just replace all of your lamps at home with lava lamps. I don't know how that helps anything, but it looks cool.

"If you're not careful and you no-clip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in. God save you if you hear something wandering around nearby, because it sure as hell has heard you"

Have always wondered about this! Thanks BrainStuff!

Linear fluorescents are not Compact Fluorescent Lamps (CFL).

What I love about your videos is that they're nice and short. Also, yay for graphics (because my brain likes pictures)! Keep it up guys :)

Actually, it's a tad more complicated than *just magnetostriction*. If you have a fairly recent well built fixture, the noise is very minimal. pretty much to the point it's almost completely unnoticeable in a dead silent room. The reason a fixture which was once silent would become noisy and create that hum has a couple reasons. 1, the ballast itself gets quite hot when in operation. enough to cause fairly significant thermal expansion of the core. 2, the ballast likely undergoes many heat cycles from being switched on and off and 3, the forces of magnetostriction cause the core of the ballast to vibrate a bit when in operation. combine the temperature cycles and the high operating temperature of the ballast with age (say, a good 15-20 years on a well made ballast) and you end up with a failure of the adhesive that holds the iron core's laminations together, which can allow them to resonate against each other due to the magnetic field generated by the coil. this is where you get that loud and obnoxious buzzing noise from. It's also worth noting that electronically ballasted fixtures (which pretty much all recent ones are) don't exhibit these behaviors as their inductors are much smaller and operate at frequencies inaudible to the human ear. not to mention they don't rely on electromagnetism exclusively for current limiting.

This was a great explanation of fluorescent lighting, thank you so much!

this guy is confusing CFLs with normal fluorescent lights

LED was indeed the light of the future.

CFLs, or Compact flurolecent Light bbs, don't really buzz, at least in my experience. Josh keeps confusing between CFL and FL, which are different. CFL is the twisty bulbs that fits into the traditional light sockets. They are pretty silent. In my experience, it is the Flurolecent bulbs, which are the straight stick ones, that buzz. But the worst Buzz I've encountered are from school's gym lights. Not sure what they are

I love ballast buzzing, at 50Hz it's more pleasing. :D

Beautiful video, I loved this.

CFLs barely deserve a mention since modern CFLs use electronic ballasts.

1) Shows a linear fluorescent but proclaim as being a CFL. 2) Electronic ballast don't create hum & replaced magnetic ballast for around a decade now.

Thank you for your informative video!

This week's BrainStuff - HowStuffWorks video asks: Why do fluorescent lights make that buzzing noise?

Because of the buzzing fluorescent lights, I failed two of my finals. So yes, it does get to me.

his last name is strickland? hehe propane..

I use a fluorescent light in my basement since i use a computer alot, and a light that would leave streaks of light in my eyes when i blink wouldnt be desirable (Also since the design of them lights up more space) Whenever i have my headphones off, that noise drives me absolutely insane, even with them on, i can hear it loud and clear You can hear it through the floor into the living room, and whenever im talking to someone via skype, they cant hear me at all

You guys should do a video on why a ship is a ship and a boat is a boat, and why its completely different. that'd be interesting because one of my favorite jokes is the "Its not a boat, its a Ship!" joke

Amazing video =D

In a building I manage I have vanities that take 4 bulbs. In one particular installation we have gone from incandescent to LEDs (60W) in trying to get rid of the humming sound, but to no effect. There is only a simple on/off switch in the cct. CFLs have shown to have a similar sound after warming up. Might you be able to tell me 'what's up with that?' thank you

I actually like the hum of florescent lights

I have tinnitus. So I hear a buzzing all the time thus I don't even notice it

I got an ad for fixing fluorescent light bulbs before this video began.

I worked at a business college for a time and as I am not a young lad any more l couldn't always hear that annoying buzz but the younger students could. It wouldn't be present at first but the longer the lights were on, the more it would buzz. I did indeed replace many florescent lights in my time. The noise is like a tiny critter is in your head and is sliding a knitting needle in and out of the ear really slowly. 😩

I actually prefer far beyond fluorescent than LED. I think the greatest thing you can do if your ballast is humming is replacing it with an electronic one, which may not last that longer than a magnetic one but shure it will not hum, maybe at all!

the considerate amount of voltage is about 25kv or higher depending on the type of fluorescent starter and ballast, also the buzzing doesn't come from the tube itself, it comes from the ballast, much like when you hear the hum or buzz from the transformer in some electrical appliances and devices. one of the ways I know this is mainly because I looked into lighting for a decent sized portion of my life.

Ballast ( or choke) does not serve to limit current. Actually it serves to rise voltage to achieve to "breaking" point from filament to filament. Once that point is achieved you have plasma which regulates it self (R C circuit effect)

Dude this sound makes me go insane 😭😭

Good stuff

In prison lock up these stay on 24/7. Its so fuckin bad bruh 😂😭😭

amazing!

Got on this video by mistake. 2 months ago my dad mounted a new light bulb in my room, is like a circle and it flashes for 4-5 seconds, then it turns on and makes a noise, didnt checked why this makes sound. I throught it was because it was cheap (10 USD) but now I know why it hurts my ears. Gonna ask him to replace it asap.

No i mean that weird satisfying buzz i hear when its early in the morning

What about if the light is turned off?I hear a humming noise between midnight and dawn.

So how do CFLs die and why do they turn black at the ends when they are about to?

I LOVE THAT SOUND

question, what about the UK, since we run on 50 herts, and my house's kitchen light is a long Fluorescent tube-based light that doesn't audibility buzz, despite being there since we first moved in over 14 years ago?

Long, straight tubes are not CFLs as they are not COMPACT. The buzzing only happens with older magnetic ballasts and not the newer instant-start electronic ballasts, which don't flicker or buzz, but must be used with new thinner T8 bulbs. If you replace the bulbs and the ballast, it won't "go bad" as you have replaced 100% of the functioning part of the fixture (or Lumiere). Side note as an electrician: leave new bulbs on (and replace as a set) for 24 hours for longer life and faster starting. Then, use as desired.

Do you hate buzzing fluorescent lights as much as we do? Jonathan explains why they keep annoying us.

There was no real reason to mention CFL's in this video apart from the fact they may be the solution to the low frequency buzzing problems and the cause of high frequency buzzing problems :-).

Does this noise stop. Is it dangerous.

I like the brightness but hate the buzziness!! Thanks . But most of it went right over my head++++get it?!?! Amy

I used to hear it only it was noticeably LOUDER.

Sis that sound comes from the backrooms

Nautilus on his shirt? Do I smell... LEAGUE OF LEGENDS!?

Are you sure the Mercury is Liquid ? I was under the impression it was in a powder form, which electrically excited, forms a gaseous state when charged. Its basically the same thing, but I wasn't aware of the mercury being in a liquid state. Nice Video though. Well presented and well scripted. Shame you didn't have any examples to demonstrate. Would love to know a bit more about what physically causes the ballast to vibrate so. I have a set of ( former ) kitchen strip lights I mounted to a picture frame as a sunglass compensator/work light. One of the buggers buzzes. They must have the ballast built into the housing. Tried swapping the bulbs about. But its from the unit itself. Might rewire to see if running them in parallel works better than series ( last one is the buzzer )

Hey Brain Stuff this video is great! If you could make a video about why looking at a computer or TV screen in the dark is bad for your eyes, I would really appreciate that!

Just reminds me of I’m at venue somewhere with a vending machine

It buzzes and bee haunts the house

interesting. I had many hypotheses, but this was not one of them.

Apparently the sound of buzzing fluorescent lights bothered me as a child in school but now I have to be honest with you, I doubt I'd really notice it. I'd just block it out most likely. Actually, using it as a background white noise would likely help me sleep.

It's the ballast that makes noise.

Nice to know...

How come plants can be grown using CFL bulbs? I don't get it. Is it because it converts electricity into ultraviolet light?

What does it means when the buzz is really loud,very loud.

I like buzzing of T12 lamps.

I Feel Now By Preheat Start Electronic Ballast For Fluorescent Long Life Just Amazing~~

btw a cfl and fluorescent tube are different.

Can a broke pin be put back in?

maybe mention right off if it is a hazard when that happens. Thats all I came here for

i want a video on led bulbs!!!

I got rid of the buzz by retrofitting to direct wired LED lights. If you are not a DIY person just get the LED tubes that are sold to replace your existing fluorescent bulbs.

Leave your backroom comments here

There is a LED light bulb in my dad’s closet and it makes a noticeable buzzing noise. It is not a fluorescent since I changed it out.

that buzz actually helps me focus

Tell us about propane and alcoholism Mr Strickland

I like a different kind of buzz

Question. Is sugary beverages as destructive to the body as alcoholic beverages, long term?

Yes, my classroom has a buzzing fluorescent light it’s actually annoying.

for some reason i didnt expect you to sound like that. you look like you should sound like stone cold steve austin.

Or just Use good German Ballasts :D They never fail and buzz or humm. Or just Use Electronic Ballasts

Idk why, But i can never hear this "buzz" Is it because i have hearing damage? Or do i never notice it?

Fluorescent and Led are much more better than incandescent but i must agree that Led are better than fluorescent

I thought it was just me because I thought it had to do with my hearing aids

In India almost 60% people started using LED lights .

the high pitched noise I hear gives me nausea and headaches

And why do 230volt ones not hum

Is there any reason why CFL bulbs have those twisty shapes?

Why do dogs have flat tongues ?

led got a big downside too.. bigger downside than some buzz, they’re expensive as hell..

can thay make tv's look better. like wat u see in a shop

I still prefer incandescent bulbs, the light is warmer (literally and the color) and you don't need a haz-mat crew to clean it up if it breaks nor do you have to throw them out carefully, to a recycle center. CFLs are _terrible_. I agree LEDs are much better, but still, not a warm light and the color is off.

Took him nearly 3 minutes to get to the point about the buzzing noise and I still don’t know how to fix it. Got bored of this video

Why does the US have 120V/60Hz while the EU has 240V/50Hz? It seems smarter to have a higher voltage and less current for the same power, since it's the current that induces voltage loss over distance and also creates more heat in power appliances. Was it purely because of history?

I prefer Home Alone... Get rid Buzz! #mccaulkin

420 ayyyy

The circuit diagram is wrong...

Very unenlightening. It's like telling me why my basement is flooded when I want to know how to pump it out. Replace the bulb? Duh, but doesn't work.

I just got a new bulb why is it still buzzing

Light bulbs are a bright idea... Watt?

Kids should be seen and not heard in any era.

what if your fluorescents hum?

I just got a lamp from Walmart. That you can charge your cell phone on too. This sound is annoying. I can’t stand it.

Any sound designers in here?
