[@____________________________.x]

for anyone like myself wondering about that dented tube: "The indented glass tube decreases the distance mercury ions diffuse to the wall, thereby increasing the ambipolar ion loss rate, which in turn increases electron temperatures. This leads to reduced electron density, and hence increased lamp efficacy."

[@aaronbrandenburg2441]

I always thought what was going on with the Power power through fluorescence to increase light output and efficiency was just more surface area and more phosphor getting in contact with UV emissions. And along with that the more Meandering path effectively creates a longer tube in a way and also just allows more area and effectively Justin more efficient lamp by creating a pseudo longer fluorescent I know it's kind of simplified and may not be exactly right but that's what I thought even since I first saw the power group for the first time what seems like eons ago. I remember often times seeing power grew fluorescence in the canopy type over hanging roofs jutting out over the storefronts outdoors here in the United States that's for the most part where I saw them. Also any clue what that have coded tube would have been used for I'm guessing it was for demonstration purposes but no clue if anyone could fill me in be great! Someone actually gave me a couple old fluorescent starters since they knew I was into electrical Antiquities and stuff. like that just to have a couple samples of some old ones. Some of them even had a screw base on them can't remember which size probably intermediate screw base but could be some other size not sure. Also had a couple that were bayonet Bass as well as some that were just a pair of pins that would plug into some socket that was unknown to me! Pretty sure it was not the same size across as the small fluorescent tubes look more like something that would be a plug in an old that would have the old insulating disc and just depends and the wire solder into it. Sometimes use for speakers or other purposes inside old radios and TVs not surprising if what they called the radio bases on some fluorescent tubes were based on this or perhaps even essentially the same sort of connector but just used in fluorescent fixtures possibly or it could be in name only. Also one on things this day I'm trying to figure out at the old church the. downstairs there was this 4-pin plug that was a tube socket type male plug.. black apparently metal housing around the plug I think that all four wires were connected it was the old cloth covered or something somewhere possibly silk covered very similar to what would be in an old radio that almost jute colored wire that sort of thing. I suspect it might have had something to do with an over audio system but not sure what was above there but it was in the hallway hanging down about a foot or less. Couple times I was good and tempted to lift that acoustical tile ceiling tile there at least see where the wire was going although it may have only had two wires connected but I think it was all four pins in gears it almost look about what would be on some rectifier tubes it's possible it was a different 4-pin connector note it was not those little small ones like used to be on car radios and other equipment typically wisdom plastic or or Bakelite plug. And I do not believe this was telephone although it had been suggested possibly obsolete telephone system. Other odd stuff there too as well. In the sanctuary about toward middle of the edge of the stage along with a few other Mike Jacks and some other unknown connectors. The thing that sticks out the most and is most out of place. 8 Pin octal socket mounted on Single Gang brass wall plate Marion horizontally in the floor above the carpet just like everything else. Also in the basement in the vicinity actually in-room opposite that hallway word at 1 odd 4 wire plug was is the audio system in that area had the old Jack's if you want to call them that. That were the I guess you probably hermaphroditic audio connectors that were just a single skin doctor in Shield and had the screw thread ring on either end of the mic cables. The idea of that system being either end the cable could be a male or female. Interesting enough they had used so no more modern ones that were just a plastic molded versions of these and oftentimes they were cables in use some actually installed literally in the walls going between the choir loft and the audio system in the basement. But instead of having that connector for a mic they had an adapter screwed on for 1/4 inch extension. And talk about ground Loops yep cheater adapters with the ground chopped off everywhere. Yeah but sometimes anytime would check if there's home in the system chances are someone I forgot to plug in with those two to three adapters with the ground cut off to be used as a ground lift. Yeah I know the lot full safety never look the ground but it was old school and probably have been that way since day one! Even with my audio equipment at home I attempt to keep everything at the same ground potential. Bedroom there is one extension cord that is used for everything that needs to be on Common Ground in that area. Since things get plugged in that get connected to other equipment on the same ground specific reason for this. All on the same wall and not much load but just keeping audio and computer equipment ground common to everything to avoid problems that that could lead to equipment damage and just driving me nuts AKA excessive 60 HZ line hum! There's enough of it as it is still need to get a couple ground Loop isolators. Also the place is old enough that when we had the new construction and they had pulled out the old carpet and everything. There was evidence of the old audio system two wire twisted pair cloth covered running from the front to the back down the center Ohio either side tucked in where the carpet was attached at the edges. We suspect old speaker lines but we're not sure. Cannot remember about what the wire gauge was either. I suspect that they originally had wall box speakers maybe four of them total perhaps. I think some people call those wall baffle speakers but anyone know the proper term for those those sloped front speaker boxes like you used to see in the old schools search Republic address system sometimes called wedge speakers or otherwise still trying to figure out what to actually call them for a proper name. Also when there was some updates done after the construction I actually did salvage some of the old speakers they had old ceiling baffle speakers in some areas. They were PA system speakers but the cool thing is there was a separate woofer and tweeter in the same speaker baffle they were installed in the ceilings originally there was like three levels of it of the grill it looked like a flattened Pagoda white but Square and getting smaller as it went downward the Tweeter was in the next to the top baffle. I have used these speakers in the past in my workshop and my parents old place made a little box to go on the ceiling work great for the application plus they were actually the proper impedance! I actually just disconnected the Lauren Transformers since it was originally used 90 or whatever volt line public address speaker outputs. I've noticed a lot of these speakers are actually 8 ohms as it is. And eventually did put in a proper crossover in those speakers as well originally it was just a capacitor sounded a lot better. Eventually I actually just enclosed the back of those boxes I made for the speakers and put terminals on the Box made a nice set of speakers for an auxiliary pair. Actually put door handles on them and made a back piece as a stand and cable wrap when not in use also had the option of quarter quarter inch plug in addition to the speaker terminals so could be used portable speakers if desired still around somewhere not sure where. Along with extension cords converted to quarter inch speaker a pair of them. I do remember that the wall plate I had for the speakers in one area of the place was actually labeled left and right I think Hi-Fi speakers I believe if I remember correctly it was salvaged from an old Ford Econoline van! More friends pimped one out just as kind of the second vehicle for pulling things and getting things place to place kind of like an El Cheapo panel van just to get things from here to there when needed when pickup truck wasn't practical

[@robstamm60]

btw most of the gas we can see in the 8ft tube was not inside the tube before - there should only be around 0.3% gas in there (8ft*0.3% = 0.3 inches = 0.76cm) the rest is from dissolved air in the water which got pulled out of the water by boiling it in the vacuum.

[@Aengus42]

... and the vacuum pulled by the weight of the water. (The barometer effect)

[@gowerski]

that's what i was wondering! thanks for doing the maths

[@kpanic23]

Also it's gravity. The weight of the water column lowers the pressure inside the tube, causing the gas trapped in the tube to expand. With 8ft = 2.4m of water column, that's about 2.4kPa less than ambient pressure.

[@tibordufner4931]

​ @Les Hemmings ​ @kpanic23 you're right. still this effect could be avoided by doing a horizontal run, while the effect Rob mentions, stays true or might even be exaggeratet due to greater surface area. but that might be wrong or really, really tiny of a difference.

[@Falcrist]

RE: experiment showing gas left in the tubes Remember that the water has gas dissolved in it. You can see the water degassing as it's being pulled up the tube. Also, the pressure in that top bit of the 8 foot tube must be very low since the whole column of water is pulling down. So the vaccum is probably BETTER than what you're seeing. I wasn't expecting this.

[@Hadouken434]

I thought that, however the water isn't degassing, the pressure is so low its actually boiling at room temperature.

[@Falcrist]

@@Hadouken434 If it's boiling, it's *_definitely_* degassing. Either way, the gas at the top of the tube probably wasn't in there at the start.

[@unknowninvictus2520]

@@Falcrist Well no because once it reaches regular pressure again it will start to condense, unless it passed its critical point. As for the gases, yes true but again what can , will dissolve into the water after stabilization of the water. However, its been a while so I might be wrong about the physics. Maybe given more time to stabilize, it would be more accurate.

[@Falcrist]

@@unknowninvictus2520 It doesn't go back to regular pressure. It's at low pressure because of the 8 foot column of water pulling down on it. Also even at normal pressure and temperature the gasses don't immediately dissolve back into the water. That process takes time. Also also, if there is boiling taking place, the temperature at the top will be quite low, further reducing the speed at which those gasses would re-dissolve.

[@Falcrist]

@@unknowninvictus2520 If you want to be much more accurate, I would recommend doing this with the top of the tube right at the surface of the water. Then give it an hour for everything to settle.

Just a side note, the "phospor" coating almost never actually contains any phosphorus. en.wikipedia.org/wiki/Phosphor#Standard_phosphor_types

[@harrisonstaley7742]

I thought it was just phosphorescent, not phosphorus

[@johncoops6897]

Of course the phosphor coating doesn't contain phosphorus. For the same reason neither a Catacomb nor a Caterpillar contain any cats.

I think the biggest problem with leds is the lack of consistent quality in manufacturing

[@charlesball6519]

Cheap Chinese tubes. My first set of 4' LED tubes were off of Amazon, a voltage regulator burned out on the driver circuitry after maybe two or three years, because the tubes heat sink wasn't even touching the board. I later replaced these with Lowe's Utilitech, and they've been running for up to 10 years now, because the tubes don't have a driver circuit in them. They're designed to be used with electronic florescent ballasts

According to Andy, The worst curse word on this channel is LED😂

[@rkefreddyk]

fluorescent tube and led have both pros and cons. what it is crazy to me is all that electronics and circuits that every led lamp must have: every led must have ti so it is probably cheap and made of shit. I know that led need that to rectify the ac and ecc but why the electronics had to be hard wired with the led? would make more sense to have in 2 separate unit: the electronics unit and le light unit so you can buy and replace what you what when you need and it can also minimize waste. why replace both when you could replace one or the other? like in fluorescent tube you have the tube, the balast and the starter (in the old one).

[@olsmokey]

Andy is absolutely right though. The main problem with LEDs is reliability. I've spent a large proportion of my working life replacing damn LEDs. (LEDS, one word. Not L.E.D.s, three words. I replaced my first LED back in 1969 and we always called them LEDs not poofy L.E.D.s) I'm not changing my terminology because they are now efficient and PC. I have LED lamps throughout my house but I also have a drawer full of spares. I certainly don't believe that BS about thousands of hours operation. Thanks for the viddy Andy.

[@constantbuzz]

@@olsmokeyFor Edison base bulbs, try Phillips, and EcoSmart brands. Surprisingly, Cree has not been great for the higher cost. Been experimenting with 4-ft LED tubes, but enough years to claim a winner yet.

[@Killerjerick]

@@olsmokey There's actually a reason LEDs fail, it's all to do with planned obsolescence, LEDs can theoretically last forever, they're super efficient, don't produce much heat and are generally cheap to produce, knowing this, imagine how hard it'd be if you started a company producing LEDs, make a few billion devices, then what? Nobody ever needs an LED again, they'll never come back as a customer, it's a one stop shop. In short, LEDs are fantastic, but they aren't economically viable to run a business on.

[@casemodder89]

@@Killerjerick THAT. Is the whole point of the led misery. Designed to fail. Overdriven and undercooled = specific calculated lifespan of about 25month. So it barely endures two years of warranty. Its much like a racecar. Every meter it can drive after it went (as a winner) over the finishline was unnessecary weight/reliability somewhere on the car. The perfect car wins and falls to pieces. The perfect planned obsolescence product finishes with a 24 month 1 day lifespan and fails. Led floodlights could last 20 years. But A: the driver doesn't (for obsolecsence reasons) and B: the chips are overdriven !!AF!!. Bad cooling by design and no cooling at all in retrofit lightfixtures (as they were designed for incandecant bulbs) don't really help on that. So either design + build your own led fixtures or stand with discharge lamps as long as possible. T5 are quite efficient and run for over 10 years on electronic ballast.

[@cal5566]

I honestly never knew what was in the starter, thought it was just a capacitor

[@ferrumignis]

They usually have a capacitor as well which serves a similar purpose to the "condenser" in the old points ignition systems on cars, it allows the contacts to open cleanly with minimal arcing which provides a higher voltage kick from the ballast to strike the tube. They also helps to reduce radio interference.

[@danmackintosh6325]

You have not lived then... I was gutting starters & twisting the innards together before my teenage years! (Because we were piss poor and doing that was my solution to getting weak tubes going quicker... That and capacitive coupling them with the hand on a cold day when they didn't want to fully strike, "pull" the current from the strongest end down the tube until it manages to jump the gap)

When the world needed him the most...

[@jeremytoms5163]

Love it. Used to work for furniture factories in town. They had large induction ovens for curing furniture glue and just had tube clips on the top of the ovens with a fluorescent lamps clipped in, no wiring. Because of the induced emf the lamps glowed whilst the oven was on. You could see at a glance which oven had finished its cycle by looking for the tube that was off. Also used to stand next to large transformers with fluorescent lamps and get the same effect. Made great non contact testers when you had a bank of incoming supply transformers.

[@mibars]

I've recently upgraded my garage lightning and specifically opted to use old dual 6 ft fluorescent fixtures with exposed tubes instead of LED lamps. Not only now I have control over quality and color of light, but with phase shifted tubes in each fixture I don't have issues with flicker and as an added bonus I've ended up with a power factor close to unity. Plus I love the simple looks of those 30 years old fixtures that would be otherwise scrapped!

[@Vicsonvee]

Great video, I do everything in my power to not have LED lamps in my workshop and home. in my old work shop I went out of my way to find one of the last a boxes of F96 T12 VHO 215 W lamps for my workshop. There is no LED that will match the light emitted from these laps VHO fluorescent lamps . I also have an old 250 watt mercury vapour lamp lighting up my yard for years now. I will never replace it. I have saved many old light fixtures and ballasts from the scrap yard over the years and have always found metal arm lamps fascinating. Great video again, best part was watching that POS LED lamp getting fried - made my day. Greetings from Ontario Canada.
