LED or CFL Which is Better for Lighting?

[hatfaesax]

great info ,. nice ukulele :)

[spotsledlight]

LED has a long lifespan.Driver also is an important factor to the long lifespan.

WIth a good driver,the power factor(PF) is higher,and it is not so hot outside.

[FreedomToSpeak2012]

GREAT INFORMATIONAL VIDEO. Glad I found this XD

[RiaRadioFMHD773]

The primary colours of light are: red, blue and green (you get yellow by mixing red and green) for the "cheap" white LEDs they mix blue and yellow elements which to me do not give the appearance of white. The original white LEDs had red, blue and green elements in one epoxy enclosure but had an undesirable rainbow effect. Todays white LEDs have the 3 primary colours but layered in 1 element so that they blend seemlessly. I think LEDs are the future of all lighting because of efficiency

[watchmanoftruth]

Actually CFLs put out dirty electricity...do the research

[ChilesGreen]

LED's like CFL's have issues when used in fixtures with transistorized dawn to dusk circuits. I just purchased the three pack of GE LED's sold at Costco for $19 bucks. The bulb died after one week of service in an outside fixture with dawn to dusk circuit. I replaced the bulb with a new one and in one week it died like the first one. I'll be mailing these LED's back to the manufacturer. We'll see if they live up to their warranty.

[JappyChan]

great video man. only thing that i can argue about is that leds do have to warm up. I sell leds for a living there is a bulb called the tracer bulb i sell on my website, that proves that they do in fact warm up. i would go led lights because the life time is estimated at 75,000 hours (aprox 11 years thats with out turning them off) as a CPF last about 6,000 and 15,000 hours. but it all depends what i'm doing with the light of course and what the prices of the light.

[stheodro]

Thanks for that funny review :) incandescent sluts? lol. A lot like my Ex girl :) I didn't even know automatic photocell light switch acted like dimmers? i'm subscribing to your channel forever !!! GOOOO YouTube!!!

[Heartborne7thSeeker]

I very very good video,I liked it a lot.

[ChrisCoxRox77]

LED's!!!!



[TheMobiusTrap]

How do LEDs react to dimmers? You showed Incandescent Vs CFL on dimmers. but not the LEDs.

[valhar2000]

@TheMobiusTrap: you need a special current regulator that supports dimming. Without that the LED will not react well to the electrical signal coming from the dimmer.

[AndyD89]

Can you tell us as an update whether the LED bulb really did keep the bugs away (or at least helped to minimise them) on your porch? Thanks!

[REPENTLuke13three]

will you think about doing a video like this one that you turn the lights off in the room to show how much light they put off.

[odiousominious]

not on their way out

the oven needs them

it can't use florescence

[gman5541]

Yes, incandescents bulbs are dirty, slutty, and energy guzzling.

[Load1Bongs1Not1Guns]

is that an extractor fan I hear in the background?

[jukejeff]

@Load1Bongs1Not1Guns No, the noise was just my computer.

[boombap420]

@Load1Bongs1Not1Guns hes just sayin that. we all know wutz lurkin behind those blinds

[herviews]

lol...I will never look at my incandescent bulb the same anymore.  You dirty, dirty bulb.

[tonisirl]

press like for mustache :)))

[maakjar]

LOL I will forever see incandescent bulbs as sluts

[cdltpx]

As for your light being invisible to bugs forget about it I walk with my led head lamp and it attacts bugs just the same. So that theory is not proven in my neck of the woods.

[shredder2468]

your amazing keep up the good work

[Xclibur2001]

Damn that's cool, I didn't know cameras could see infrared photo diodes giving off light. Now I know how to test my remotes when they go bad.............Thanks a lot Jukejeff.

[jpostDesign]

Ever test that LED outside to see if bugs are more or less attracted to it than a normal bulb or CFL?

[clintmiller38]

LOL' the incandescent is the slut of the lighting world'! What a great analogy. :) Good video explaining the basics.

[clintmiller38]

LOL' the incandescent is the slut of the lighting world'! What a great analogy. :)

[marpoq]

thanks for this video! i am going to look into LED bulbs

[derekstech]

Thats not the same LED thats in the LED light bulb though.

[annahasier]

The US military has always been on lead with energy retrofit projects for their bases. With LED & CFL installations this has proven to be a problem so this is what they did

On 3/18/10 they issued a memorandum that affects all bases & banned all LED installs because of LED & CFL lamp failures, warranty issues on page 17 & lumen output issues in 8-6. sound familiar

see the doc on the inda-gro home page 'compare' link.  narrow spectrum reduces photomorphogenesis its the 'emerson effect'

[Griffith181]

You sure know alot about bulbs :)

[1theblacksmith1]

Do you grow cannabis?

[marcvie9]

@1theblacksmith1 i think so

[Jeorney]

Another consideration is the method of disposal of old or broken CFLs'. You can't just throw them into the bin. This is because of the Mercury (Hg) they contain is a potential health risk and environmental hazzard.

[dotcombatgames]

did you just call that lightbulb a slut!? oh and yes you are correct they are called reostats or varible resisters, very good job mate! i learned a few things here had no idea you couldn't put those on dimmer circuits

[dotcombatgames]

now we just need to start making new lampshades

[jimmymac61]

I never thought of incandescent lights as being sluts before.

[TheNuclearWatermelon]

Yeah, but only around 0.5% of the ultraviolet light escapes from CFLs. 99.5% is absorbed by the phosphorus coating.

[jukejeff]

@TheNuclearWatermelon

Almost all CFLs are made in China and I am not sure that all the lights are up to the manufacturers specifications.

I quote, “Early in October 2008, only months before Health Canada announced an investigation into CFLs, the British Health Protection Agency (HPA) cautioned CFLs sometimes emit UV radiation that is beyond acceptable safety levels.

Nine out of 53 CFL bulbs the HPA investigated emitted unacceptable levels of UV radiation.”

[valhar2000]

Jukejeff, why don't you do a vlog about the efficiencies of different lights? These videos you make in which you explain how things work are fascinating.

[jukejeff]

@valhar2000 I will consider doing a vlog on different light efficiencies. Thanks

[psyfertech]

dude you explained light bulbs so cool

the normal bulbs are sluts, they take it any way lol

cfl bulbs only like the good electrons lol

and i would say leds only like dc current at the correct voltage lol they have to be perfect

[robertgift]

@jukejeff Thank you.

The full-wave rectifier diverts the negative half of the sine wave to positive. Still, it allows a Zero between peaks.

Is that zero vicinity filled in with a capacitor so that there is no flicker?

A female RN reports that she experiences flushing and other symptoms in fluorescent tube lighted rooms. Is it the frequencies of light emitted by the phosphors or the 120 pulses/second? If the latter, the LED light, reacting even faster than phosphors, could be even worse.

[jukejeff]

@robertgift Yes, the good LED lights have a capacitor. I have a newer You tube review of some better LED lights. Check out this picture inside a good LED light, you can see the capacitors. I put a link to the picture below this video. You are not allowed to put a link here.

[robertgift]

CFLs flicker 120/second. Incandescent bulbs do not.

Do LEDs flicker? Or do they have a filter capacitor to fill in zero and negative sections of the sine wave?

[jukejeff]

@robertgift Yes, cheaper LED lights do flicker. But the better made LED lights do not flicker. The best LED lights use a device known as a rectifier which converts alternating current(AC) to direct current(DC). The result of the rectification is a LED light that is substantially brighter and has no visible "flicker".

[DarkSideDeviance]

i was about to ask a question when i realized only stupid people ask questions on the internet because all the anwsers are right infront of them. thanks for the insight sir

[kezza069]

leds should flicker is wired up corectly.. very fast you cant see it! if you wave an led light that is set up right it will flicker as you mive it and you will see it!

lol filaments are durty durty sluts LOL CCFL and CFL lighting will be out b4 you know it! and banks of 1W star leds will rule over the world! lol

good video mate! very funny too :)

[PeacemanKeo]

This video is really educational

i learned quite abit from your video

[beersandank]

6:10 dirty dirty boys!!! thanks for the laughs you wierdo.

[beersandank]

is this guy stoned or is it just me. Hey jeff which one grows weed better? If your sober and you just play with lights and a video camera i would be a little concerend with my mental state if i was you. you probably did a lot of acid back in the day. Unchain all those kids in your basement you serial killer freakshow. 6:10 fucking hilarious

[quiteobserver]

i still don't understand why cfl's shouldn't be placed near photocells

[TheGeek1028]

7:30

[quiteobserver]

LED does not flicker whereas CFL does....

[quiteobserver]

very nice tutorial

[jukejeff]

The bugs were not attracted to the LED lights last summer. I would say it cut down about 90% of the bugs around the outside lights. They would fly around our windows because I have CFL's in the house and they wanted in.

[WangChan]

@jukejeff i believe the reason is due to the heat it given off. As they tend to find heat source as CFL and conventional light bulb burn at a higher temperature.

[maximusmku]

This video is cool. I like it.

[noreaga12326]

JEFF... nice video. the best lighting i liked is the one ur planning on using on ur porch light next summer. Theres something i must correct u on. The incandecents we use today are mostly heat but to me its not wasted heat. I live in the north east in New York City and every bit of heat is welcomed for me and many of us living here. U may not be aware of this but as i stated in other videos, incandecents are not totally going away. They're making energy efficient incandecents.

[monicapie90]

I nearly had a heart attack at 3:18

[ArchNME]

Hey, great informative video. Please tell me, how did the led bulb work out with the bugs? Were they still attracted to it?

[jukejeff]

@ArchNME The bugs were not attracted to the LED lights. I would say it cut down about 90% of the bugs around the outside lights. They would fly around our windows because I have CFL's in the house and they wanted in.

[woodlanduk]

Q which is better?.... well if your in the UK you only have a choice of CFL or Halogen ,....LED Not a hope in hell

[TINKIWIKI]

i have 80 led light bulbs " 3.5 watts" each and hundreds cfl light bulbs... the reason is because i have a realtive who work in a company were they make light bulbs so any scratch they have they throw them away... but my relative gets them from trash and gives them to family members lol

so i have thousands of dollars worth of light bulbs

[JaredProject]

nice vid, thanks for the info!

[williamkotz]

I own an LED Company , and we are making millions , LED is the way to go if your into ROI's on your Products in energy Saving and Maintenance cost. LED for Life

[WolYou]

LEDs have a poor photon emitting ratio. Its very good for close lighting. For bigger distances its useless. Btw, LEDs convert most of the energy to heat. Losses due to the control gear and a high refraction index of the semiconductor bring down the efficiency of a LED down to a few percent. Much worse than a common light bulb. Lets wait fo the development of an organic light source.

[Zolar1]

Hmmm, 3 watts of heat with a reasonable amount of light output versus a 60 watt incandescent bulb's heat output = HOW DO YOU FIGURE???

Even if I used 7 watts LED compared to a 60watt LED I still make less heat.

7w is not equal to 60 watts of heat output, even if the 7 w was a pure flame.

[yousahil]

6w led gives the same lumens as a 60w "common light bulb". bring down the efficiency of a LED? Much worse than a common light bulb? are you on weed?

[GRiZLOC]

Nice video jeff...u can check my video out about my chinese 3x1 watts warm white edison powerleds or my 4 watt cree warm white leds in my channel.

Please rate it or put a comment of what u think...

[killcar5nbike2]

Nice work, I know from an engineers point of view it is very hard to explain how any electronic equipment works without getting the 'what's he on about' blank face expression.

Not entirely corrrect on all aspects (just due to trying keep it simple) but very helpfull to those interested.

BTW it's actually dusk till dawn switches that don'tlike CFLs. The bi-metal strip heated relay ones aren't bothered but the electronic solid state ones can't handle the current/voltage phase lag from CFLs.

[jukerandall]

Jeff, you're brilliant ... like a ligtbulb!

[jro910]

I was enthralled...a lot of info!

[michalo2]

Interesting. What's efficient, warm light and can work with a dimmer?

[jukejeff]

Efficiency is how many lumens you get per watt used. The more lumens the higher the efficiency. Cool white LEDs are generally more efficient then warm LEDs. Warm light LEDs start out as a yellow LED and made into white, so they have a yellowish tint. LED lights will work with a dimmer, but they do not get dim. You have to turn the dimmer all the way down before they lose luminosity.

[diezungen]

LED lightbulbs....the first I've seen. Thanks.
