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 :)

My favourite light source

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.

Haha no idea how I ended up here bit glad I did! Good stuff + well explained.

Nice video. Thank you.

Thanks, very helpful.

good video.

at 5:13 is that light fixture a Sylvania Miralume? I have one similar.

nice video, very helpful

just great!!!!!!

really useful videos i found that u have uploaded.. thankz for the fine explanations ..really found it very useful (y)

Amazing technology still going strong. Much better light than led.

beaUTIFUL START !

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

Very Good Video 😇

Cool.

whats the intro song? I love it

what do you thinks best instant on or rapid start

What music is used at 7:42?

what is the music used in the intro scene

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 is the music starting at 5:57 ?

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?

Today the LEDs are unbeatable.

when a fluorescent lamp burns out what usually goes the mercury gas or the filiments

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

preheat was in the pat including t12 bulbs. everything is being replaced with instant start t8 ballasts because they save energy

when a lamp burns up what usually goes hte ends or the gas ect

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...

it is AC, so it is switching back and forth. Both sides are both anode and cathode depending on the moment.

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?

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?

These cant be beatenn LED: Hold my beer

They don't want to ignite when temps drop below 32 degrees F (0 C). Any solutions? LEDs will replace flourescents, I predict.

Video actually starts at 1:00

Great video. I wonder why sometimes the light can go pink/purple as the lamp ages.

@porcupinepunch6893

That's because the phosphor coating on the lamp eventually degrades and it stops converting the blue light as efficiently.

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?

Umm......just a question......shouldn't one electrode be a cathode and one an anode for current flow.....how come both are cathodes?

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

The ballast is a load that keeps current flowing even if the gas does not ignite...that's why its there.

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.

I collect old bulbs and starters.

👍👍👍👍👍

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.

Why do they make sounds sometimes

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...

Agapito Flores was the last inventor.that is why..it is called.now flourescent

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...

I guess LED will beat flourescent may be I'm not sure I hope LED better beats it

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.

uhmmm if not for controversy maybe Agapito Flores be named the inventor of the first fluorescent lamp.. just saying

I can't see your video. All there is, is a green screen.

But it is beaten by LED~~

😅

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

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?
