I am currently active duty Army deployed. I tell you what man, you've been a huge influence in my life. In a world where I was unsure if I was going to reenlist or get out because honestly I'm ready to be a civilian again. With your insites I'm proud to say I'm going to be an electrician. Tho you're recently sponsored I'd like to thank you for all the videos you did in both channels with nothing in return. Thanks man.

My understanding of the "don't touch quartz halogen lamps with bare hands" issue is that any oil deposited on the surface from the skin will burn, and the resulting remnants/soot becomes blackened carbon that absorbs more heat which creates hotspots on the surface when the lamp is burning. I though it was those hotspots/uneven temperatures that lead to premature failure.

Really in depth ....the new generation of the electrical game is fortunate to have you out here sharing this information

Love this video because you included a Mercury Vapor Bulb. As a kid back in the 70s we would play in the street under those lamps. When they came on (often with an audible buzz), it was time to go home. Thanks for all the videos, man.

As an electrical engineer just starting out, your videos are a great help! Thank you very much!

It would have been nice to have tell us about the different lamp bases. Maybe a short video on that topic? Thank you.

Omg EXCELLENT. I SELL AT Walmart in hardware I get asked 20 Times a day about lamps. I learned so much. People just don't know lamps. I had a General understanding but this helped tremendously. People come in so frustrated. Just today a lady stood and gazed 25 mins. She never asked me a question. Another was looking for a small base tube for her microwave. It looked like a E12 tube lamp. We were out she told me I'm frustrated can you help me when she came into hardware.

Lighting is an amazing subject. What's also fascinating about different light bulbs, is the shape and how the light comes out differently because of the shape.

10:50 my dad explained to me once to never touch the headlight bulb when I'm changing it because the oils on my fingers will leave a residue on the bulb that draw the Heat and will crack it...

1st educational video, complete and through. I look forward to all your episodes. Thanks

you bring back great memories of when I worked hardware retail as a electrical department manager.... you would have made a great sales person!

I expected to learn about size of the bulbs like A19 bulb with E26 Base (Standard house bulbs, in my opinion). but this was certainly an awesome video and I learned a lot. Thank you Dustin Stelzer.

2700K is a orangish yellow. 3000K is a whitish yellow. 3500K is a yellowish white. 4000K is pure white. 4100K is a slightly blue light. 5000K is a bluish white. 6500K is a purplish blue.

Will you have a video going into all the bulb/lamp/socket shapes and names (like E26, E27 and A19)? Also maybe something about preheat vs instant start fluorescent lights? (and info about ballasts, starters, etc).

Your channel i didnt know i need, i got this strange fascination on learning how things work and you explained a lot to feed my curiosity on these different bulbs. A lot i knew already but stuff like the halogen bulbs, i always thought the halogen gas itself made the filament glow brighter, but in reality it only allows the smaller filament glow hotter. Fascinating stuff!

Absolutely loved the explanation. Finally understand why the heat sink of my LED headlights gets so hot. Thank you!

i have had a CFL overheat cause of the type of fixture it was in. always make sure with CFLs that the lamp has adequate ventilation to stop the ballast from overheating

Currently viewing this in lighting essentials class. How has noone asked about your bruise? yeesh bro. Well explained. thank u

Interesting on the halogen explanation, my dad always told me it was the oils on your skin getting on the bulb would create a hot spot on the glass and cause the bulb to break and fail

Actually, the LEDs are the only ones you can accurately call a light. The rest produce far more heat than light. They are heaters that can also light a room. LEDs produce mostly light. Some do generate a lot of heat but that's usually due to an inefficient circuit design and not the diodes themselves. They have to convert 110ac to around 3dc. A quick and dirty way to do that is to burn the extra energy off as heat. That's why some have heat sinks. It's a sure sign of a poorly made bulb.

More videos I’m a 2nd year apprentice looking to advance my skills and knowledge to up my pay as well as be taken more serious in the trade. In trade school as well, more vids please, will let my friends and family know about your channel and will like and subscribe! You deserve money for your channel

I'm liking this video just because you compared 2700K to the look of dehydrated urine! And thank you for reminding us to match up the lumen output too. This is often overlooked when the other criteria are matched up.

I have seen 12 volt bulbs with an e26 base before mainly in fairgrounds and it really stumped me for a bit. Also fun fact an incandescent filament isn't just a coil, it's a coil that's been coiled up. The coil you notice first is actually made out of a coil of wire to begin with.

Hey Dustin, I love this video! My love for lamps is borderline unhealthy. As a union stagehand, I get pick of the litter for pretty and damaged lamps. It would be so fun to have a short video on why your lamp will develop bubbles and pretty colors if you don't handle with gloves.

After I watched this channel. This is school should teaching. Fastest and easy to understand to electrical freedom.

The halogen bulbs where you *will* want to use the gloves are the ones you typically find in car headlights. For more than you ever wanted to know about LED bulbs, check out Big Clive's youtube channel, where he "takes them to bits" in a great many instances.

What happened to your left biceps area?

Very helpful for us reviewing electrical technology in Architecture Field. 😊

Lamp is what it is, bulb is the format or style of the lamp. There are many formats for lamps; bulbs, tubes, diodes... etc.

You remind me so much of myself when trying to explain things. Greatly appreciated. By the way. On the high pressure sodiums the arc tube is actually made from alumina because sodium doesnt react with it like it would with glass where it will eat through it and begin to leak. Older ones will because they now use a tiny resivour at the ends to hold sodium when its cool or hasnt evaporated all of it. And it is basically spots where it pools up in a dip around the electrodes. And the incandescents are actually pretty common and are one of the only lamps/bulbs that have almost perfect balance spectrum of light of 100cri so they are used where color rendering and color quality is most important over energy usage.

Pl 7 are our old exit light we have on our university campus in Ontario Canada. We also have 4 pin 32 , 42 , 18 , lamps in hallways and main entrances. They heat alot and burn out the sockets, most of our voltage is 347, 600 ac. Led technology need to get going on this , these lamps or 30+$ each..and we buy by the cases.. crazy. And good to not every manufacturer has a different rating. It's a trial and error issue..Love the videos Dustin, keep it up. Cheers buddy 👍👍

Just curious, with incandescent light blubs is there a particular colour or level or brightness that is beneficial for heath. For example, is there a colour which would be appropriate for the bedroom, bathroom, kitchen and work/study room

Oddly enough, George Rodgers was the guy that guided me to my Master electrician license. What a great chap he was!

Keep it up amigo !!! Blessings

I think it's the other way around, high power bulbs have a thick filament and burn hotter for the same life. A small fridge bulb of 10w has a thin uncoiled wire stretched out in several lines and really wobbly. 12V halogens have a thick filament last very long with an inductive power supply. 30W on 230V installed horizonally stretches the filament under its own weight. CFLs operate at too high power (20w, yours says 42w) that rises up into the small ballast if installed base up. Worse than LEDs. Metal halide is one of the best lamps with close to continuous white light. I remember mercury street lamps producing a weird blue light that seemed bright, but it was not possible to read under it or see grey LCD screens. They looked nice in winter with snow.

I am so happy that you’re going 0:09

Great video thank you so much for spending the time to inform us. Please make a video on Dimmers (Incandescent, Electronic, Magnetic, Etc...) Plsssss

Well illustrated with superb explanation.

My area light stop working. It uses 250w HPS bulb. I still have a good bulb but looks like the ballast is no good. I cant find a new area light that can withstand this 250w HPS bulb. Can i just replace the ballast? Any input is appreciated. Great channel btw. You've helped me out on all my electrical situations

Dude super super useful, thanks from U.K. 👍 🇬🇧

not from the US, but lamp is still used my my language, and we use it for the thing that a bulb goes into, that is the "housing"

Great video as always!

Extremely educational keep up the great work brother

Wow! You are amazing, Electrician U!!! Thanks for sharing.

would like to know what type of light bulb can be used in a hot southern attic?Thanks

Hey great video! Keep it up!!

Great, informational video! Thanks!

Use of polycrystalline alumina in high pressure sodium lamps is due to liquid sodium and sodium plasma being _very_ corrosive to quartz. Also, the plasma in a HPS lamp is too cool to excite the mercury which contributes little to no light of its own. It's job is as a buffer gas to drive up plasma resistivity and thus allow for shorter arc tubes. Mercury free HPS lamps exist, and they have much longer arc tubes to correct for the lower sodium plasma impedance.

I would like a video that gives focus to safety tips for beginners on the job such as before they do task A or B they need to make sure they do/look out for these things first. So basically how to approach a job appropriately.

In Germany incandescent-bulbs regularly are named "Glühbirne', what literally means "glow-pear"...

How to test things like fuses, capacitors, refrigerator condensers etc.... Please and thank you!

Excellent detail but one finnicky point: LEDs don't use a ballast; they use a driver. Ballasts are for fluorescents.

Thank you for all of these informative videos. I'm perusing a career in this field, currently in the stage of looking for a company and sponsor to endorse me. This material will help a great deal to start and down the road!

Ouch! What did you do to your arm?!

Good video, I did notice you did not mention induction lamps.

Very thorough!!

Nice explanation of lighting types

Super helpful! Amazing work as always+

The only thing about incandescent light bulbs is something the filament might be broken but touching lightly. It will give you a reading on Ohm meter but when power is turned on filament is open where there is no light. I've ran across that quite a few times. ELO👾

Nice bulbs there just reminded me to buy some kind like them

Great job man

At 20:22 LEDs do not use ballasts they use drivers to drive the circuit. Great video, thank you.

Totally dig this video..

I wish he had a section about bases as well (a19, candelabra, plug on etc)

Great Video.....

most modern ballasts don't preheat the cathodes anymore, they just send a blast of high voltage through them, this shortens the life of the ballast but people want it to start instantly so that is what you get now.

Not to mention the filament in that high pressure sodium lights make for a great knife sharpener!

Great vid. Now what is the base size of the halide or halogen bulbs and can I change them to a led and where can I find them

Dustin, is it true that if you don't change burned-out fluorescent bulbs that the ballast will burn out attempting to start the bulbs? In other words, the ballast stays in startup mode and burns out faster?

High pressure sodium Is my favourite of all types

Can you dim floursent bulbs

Well explained

Hi Electric Your Videos Are Good!, Keep Up the Good Work

I really liked the video style but however sadly in every single lamp you gave wrong information some kind of another. Incandescent: the smaller Bild does not have a thicker filament, that would directly imply a MUCH lower resistance thus higher wattage (r proportional to area/length if you would increase area and decrease length the resistance would go WAY down, that would be basic understanding) Halogen: it burns hotter than normal incandescent but in the same conditions will feel cooler on the skin since the whole thing about getting the filament hotter is the reason to put more energy into the visible spectrum which was in infrared (heating) before. Example: two 20W lamps: both have 20W power going in, normal one wastes 19,5W as heat, halogen wastes 19W as heat thus would not feel as hot in the same focusing spot. Fluorescent: filaments are made of nearly same material than the two types before BUT coated in a thermal emissive coating. The spacing of the electrodes does not matter and that’s not the reason the phosphorus is required, it’s pressure and implied intensity. The tube is low pressure. Compact fluorescent: If you broke the glass they will immediately fail. Twisting at the tube will most likely destroy it instantly if it does at all. The electrode wires are not connected to the plastic base thus if you break something it’s the envelope or the glue, IF you than keep abusing you can demage the seal which will kill the lamp slowly LED: ABSOLUTELY WRONG! they DO NOT burn hot! The color temp CAN seem Hot (blueish) but the light itself is emitted at the recombination of electrons and holes thus giving of a photon of E = h * 1/lambda = Bandgap thus this process produces very low heat per unit of light. Also no one cares about wattage. Important are: lumens, CCT and CRI. HID: Arc dips because of gravity? Inside an atmosphere? Really… not rising because of thermals? I know it’s not really important but it shows total misunderstanding in the field. HPS: chemical reaction between the contents and glass makes it incompatible! MV: Phosphorus fluorescences NOT white, it ADDS spikes in the red to green spectrum.

Hi Dustin, I love these your episodes of ELECTRICIAN U. I have a semi-old Florescent lamp in my kitchen ceiling. I heard that if I replace the Balas & the lamps I can have better lighting in my kitchen. Is that true? Can I do that?

Great video! I am curious to ask what is the job of the igniter on the metal haylide and the high pressure sodium?

Thanks

Thanks brother, another awesome video ,but LED’s have drivers not ballasts.

On one switch can you use led bulbs and incandescent bulbs?

What happens if you put a fluorescent tube in a lamp socket and turn it on?

I worked in Distribution for GE 20+ years. Every year they would beat us to death about selling GE Lamps. I absolutely hate Lamps/Bulbs etc..... Do happy to see LED kill the traditional lamp!!!!

One thing I would have been curious about, would be HO, and VHO fluorescent lights..

What if a led has not that white stuff on it does it get hot to touch.

Question with the Compact Fluorescent. (15:45). What if the fixture has a ballast and the lamp (bulb) has one as well???

@electrician u I was wondering if you know/could let me know what website or websites I can go to to buy Hid fixtures and ballasts and bulbs and the like thanks.

Im guessing duct work on that arm wound or arm in a wall. I've been there lol. Great vid thanks for the info!

Can I replace my halogen garden lights with LED without replacing the fixture?

what about direct wire LED? There's no ballast in the fixture itself, bulb is directional. Only goes in fixture one way otherwise wont light up LED drop in /direct replacement for CFL can be fickle when comes to the ballast in existing light fixture

I work in the film industry and we call them globes. The terms are all pretty much interchangeable in my opinion tho.

Fluorescent ☑️ incandescent ☑️ hid☑️ mercury vapor ☑️ halogen ☑️ LED ✖️

Add led Edison light bulbs

You're awesome 🤩🤩🤩🤩🤩🤩🤩🤩

bravo!

Just want to point out, a 1200 lumen light is not twice as bright as a 600 lumen. Brightness from lumens is measured with a cubed root. So to get twice as much brightness as a 600 lumen lamp you would need ((600^(1/3))*2)^3 = 4800 lumens.

Thank you very much for the video. You should break this video in 8 minutes part videos. Little drops of wisdom! 😉😁🤔👍

Hey, like ur video, please, can u explain me the difference between elipsoidal bulb and parabolic bulb? please

First!!! Can't wait to watch the new episode.

This is interesting to hear "lamp vs bulb" because my British ass thinks bulbs is what you put in lamps. The Lamps is the housing.

that not even aall, theres some more, like sox (low pressure sodium) which is the same as hps but lower pressure, it may also use different gases, and dont forget plain xenon lamps to.

.Good Video
