- Introduction to fluorescent lamps: How it works, inventors, animations. The fluorescent light is the most prolific type of lamp in the world. For indoor lighting it remains the lowest cost efficient light source. Inventors include George Inman, Richard Thayer, Edmund Germer, Albert Hull, Ed Hammer, John Anderson. GE, Westinghouse, Sylvania, OSRAM, Philips all contributed to the fluorescent lamp. It uses two electrodes which send current through argon and mercury vapor to make UV light. The UV light strikes phosphors which convert the energy into visible light.

My favourite light source
Thank you! Thank you thank you! I've been trying to research how flourescent lamps have different spectrums and this video explains everything so well!
Wow! Just WOW! you, sir are incredibly knowledgeable about lights. Thank you for this very well made video! Excellent!
Wow! Thanks for sharing the beautiful history of lamp :)
Haha no idea how I ended up here bit glad I did! Good stuff + well explained.
Absolutely FANTASTIC video!!! Thank you so much for sharing your immense knowledge and experience with us! :-D
I been around town changing out old T12s in old filling stations and replacing with LEDs and i came across a T12 ballast to a twin 8ft. pin type that had a 1972 date on it...and yes it was still in service.
Nice video. Thank you.
Amazing technology still going strong. Much better light than led.
Thanks, very helpful.
really useful videos i found that u have uploaded.. thankz for the fine explanations ..really found it very useful (y)
nice video, very helpful
Today the LEDs are unbeatable.
good video.
just great!!!!!!
Th actual creator (my great grandpa) is the inventor of the glass tubing around the neon lights
Thanks for the vid, needed for some lighter research
beaUTIFUL START !
Very Good Video 😇
Cool.
at 5:13 is that light fixture a Sylvania Miralume? I have one similar.
preheat was in the pat including t12 bulbs.
everything is being replaced with instant start t8 ballasts because they save energy
Video actually starts at 1:00
it is AC, so it is switching back and forth. Both sides are both anode and cathode depending on the moment.
whats the intro song? I love it
what do you thinks best instant on or rapid start
love the way Mr DeLair doesn't BS about pros and cons.Some so called experts
often say things so the agenda would be best served.Opposed
to conveying facts.Denying the less learned the
ability to have basic facts as building blocks for thought.
when a fluorescent lamp burns out what usually goes the mercury gas or the filiments
Great video. I wonder why sometimes the light can go pink/purple as the lamp ages.
That's because the phosphor coating on the lamp eventually degrades and it stops converting the blue light as efficiently.
I think that happens when one of the gases depletes. I think Argon?
A mí me avían dicho que hera por problemas de mercurio
@@shaunclarke94I believe mercury.
The ballast is a load that keeps current flowing even if the gas does not ignite...that's why its there.
what is the music used in the intro scene
Uhmmm... Where is Mr. Agapito Flores? If I'm not mistaken he also made something like what Hewitt did but instead of greenish light, it produces white light. Please correct me if I'm wrong...
Can 2- 24 inch flourescent lamp fixtures be installed end to end by wiring white to white and black to black combining the two transformers?
What music is used at 7:42?
how how can i chose a Fluorescent bulb that has good reading light i like flourecent light for reading it feels natural any advice on choosing a flourecent bulb that has good clear reading luminocity
i would like to know what are the other method to start the lamp? and the different between Rapid Start Socket and Instant Start Sockets? are these another two starting method...thank you ..
i got a question, dont we use starter in the lamp anymore? or it is being replace by something else like ballast?
when a lamp burns up what usually goes hte ends or the gas ect
Actually, if you think about it, only one end is a cathode at any one moment, the other end being an anode until the polarity of the AC reverses.
Now what happens if you put a 37W lamp in a 40W fixture?
What is the music starting at 5:57 ?
These cant be beatenn
LED: Hold my beer
Question, what would cause a lighted sign when turnec on to flicker on and off constantly?
Bad bulb. Replace the lamp and it should be fine. If that doesn't solve it, then it's probably the ballast. How old is the sign?
They don't want to ignite when temps drop below 32 degrees F (0 C). Any solutions? LEDs will replace flourescents, I predict.
I collect old bulbs and starters.
👍👍👍👍👍
my biggest problem withe these lights is frequency, i can see the blinking of the light even tho i use multiple lights from each side of my office
What if we use a no florescent powder? Would it still works?
And could i place Solar Panels around in a specific distance and would it work?
No...you would have a UV (visible and invisible) lamp only.
how work in DC 220v?
my grandma has an old one like that
There is only one cathode at time and they switch sides. This was answered below.
Philips introduced the first electronic CFL in around 1982, the incandescent lamps have been obsolete for way too long to ever be used.
Umm......just a question......shouldn't one electrode be a cathode and one an anode for current flow.....how come both are cathodes?
Question: My fish tank florescent hood lamp push button switch has 4 wires, why?
It's a 2 pole switch. It's like you take 2 switches and put them in to one
EdisonTeachCenter what is your name in lighting gallery? I want to see your posts and pictures of your collection?
I think ricksbulbs
Agapito Flores was the last inventor.that is why..it is called.now flourescent
I guess LED will beat flourescent may be I'm not sure I hope LED better beats it

Why do they make sounds sometimes
the sockets dont make a difference unbless its a t5 bulb. there is instant start, preheat start, rapid start magnetic rapid start and more.
That is the correct spelling in several languages, so it is easy for that to slip through QC. How many languages do you speak? probably one...
Be very very careful with early (30s-40s) fluorescent bubs if you collect those. The phosphor is zinc beryllium silicate, which like a lot of beryllium compounds can be horribly toxic and carcinogenic. If you break one, cleaning up the phosphor powder should be done with EXTREME caution to avoid inhalation.
I was told that when the towers came down on 911 that over a million tubes were destroy ...no wonder we got so many sick people out of that mess. Sad...
uhmmm if not for controversy maybe Agapito Flores be named the inventor of the first fluorescent lamp.. just saying
I know this video is 7 years old, but wouldn’t LEDs be better overall? At least in terms of efficiency and reliability.
La luz LED es más dañina que la fluorescente
"Only a few problems,"
"Advantages outway the disadvantages,"
Uh...eye strain? Migraines? SEIZURES? RASHES?
Energy-efficient my sweaty balls, I'm sticking with incandescents. Light is far more appealing, and doesn't have such adverse effects on health in sensitive people. Eats up more electricity, but IMO it's a fair price to pay to actually get good, healthy light.
I can't see your video. All there is, is a green screen.
Dc voltage
Light pollution is a huge problem, especially in
North America.
But it is beaten by LED~~
nope
Nope. LEDs sucks
EveryoneHarmonyPeace Nope LEDs suck.
you're thinking of an X-Ray tube......
Lamp efficiency has improved dramatically. New phosphors have much better CRI and life. Modern T8 and T5 goes out to 50,000 hours now. Old T12's could never do that, T12's are not gonna be made much longer. OBSOLETE
LEDs
😅
UwU
Nicolas tesla is the best
please face reveal
skip to 0.31 for face reveal
Now tell my why ballasts are so expensive, and quit working all te time.
They're not expensive at all in the Netherlands, the armature including the ballast, two starters and two tubes can be purchased for about 20 euros over here. I've replaced my double-tubed armature this week, because the ballast quit working after 8 years of almost continues service. Not bad, right?
planned obsolescence.
because its a new technology
Made possible by a grant and you can't even care to spell "Disintegrate" correctly
I thought tesla invented this shit !!!
