@MrDeepwoodtickles These days, I like them until they stop working. Then I do not know what to do with the glass part. I have been saving the circuits. I do not mind the warmup time as long as I have some light when I turn on the switch. OLd CFLs were like long FLs: You turn on the switch and have to wait 5 second in the dark with light flashes until the constant light comes on. Sometimes the failure happens inside the bulb with part of it flickering while another section looks normal. Thanks!
I agree, there are tons of things these circuits and the parts can be re-purposed into. Various power supplies can be made, both higher and lower voltage, and the CFL can be made to run off low voltage DC using these parts and a couple from your junk bin.
Otherwise, there are many uses and applications for the majority of the components, especially the magnetics and capacitors.
@DaveArgon You are right! I have not yet use them for anything but expect to do something with them eventually. This is a situation where most of the parts remain valuable when the bulbs are discarded. Eventually a recycling center will separate the circuits from the glass and sell them. They will be even more useful when you can buy large quantities of the same model from the same manufacturer. Thanks!
@thewii552 Hi! Thank you for the information. I knew that it had to be a transformer but could not see two sets of windings. The following video supports what you said:
"Burnt CFL Re-Light" can be seen on the nomadqq.'s channel.
The circuits on his Website show full rectifiers in all the diagrams. Would that be a reliable part to recycle?
I would have to spend more than $1 to assemble a similar circuit. Thanks again!
I will watch your electronics tutorials. I just started watching Afrotec.'
@legitimatemind I honestly did not know that there was a circuit in these bulbs until one dropped and separated during the filming of my ceiling fan alternator 230+ volts video. I was just lucky that it did not break in the room. I found a store that sold them for 49 cents and bought a lot of them. I even modified a light fixture to make them look good. I should post a video about the light fixture. I think that I will even apply for a patent related to CFL. Problem: I am stuck with 3 dead CFLs.
@legitimatemind Yes indeed, you see one capacitor with a cylindrical shape. What do you call the green and the red elements?
Bulb from different companies have different circuits. I subscribed to the "nomadqqq's Channel" because he has a link under the video that will take you to a site that has lots of CFL bulb circuits. These circuits are not the most recent ones but I am sure that some of them are still in use. Of my 38 subscriptions, it is the one with icon showing the face of a black man.
p.s. incandescent,s produce a nice clean usable lightsource. the same cant be said for cfl's and when reactive power charges are implemented they will in effect cost as much as incandescent's to run, possibly more and they cost more to manufacture and pollute far more in production stages.
@MegaDRjohn You're just a grumpy traditionalist that's going to soon be unable to use his energy wasting incandescent light bulbs. And honestly who cares what's inside. People have been using Ballasts forever. They're proven safe. Oh and by the way, Mercury vapor is so thin and harmless compared to what's in a old fashioned glass thermometer. I don't know where you scared people get all this fear from. Conversation finished, go about your business.
I used to work for a company that was a broker of products once considered "e-waste" that used to go in landfills, but they were able to find a use for the products, and began selling them to various computer repair operations. Maybe one day there will be a broad industrial use for these materials. If you stockpile enough of them, maybe one day you will find a market for them.
@BooGooNFlowoo4Evoo I would even pay 25 cent to get rid of a single bulb. I am talking about the mercury filled glass part. Home Depot stopped accepting them. However, I looked for videos on Youtube showing alternative uses for the large fluorescent light ballasts but could not find any. It appears that ballast is only used in lighting. I would like to know what happens to the bulbs after you take them back to a collection location. Those who can handle the mercury will also mine components.
I think the big thing is CFL is replaced much less frequently than pld edison lamps. So if you do the math it is better for energy efficiency. At one point the idea was to make the ballast/base permanent and the lighting element could be replaced. I like using the parts. By the way I haven't replaced my full spectrum CFLs in several years. EDison bulbs I replaced every 3 months.
@izelxx1 The problem with CFL starts when they need to be replaced. Unlike soda bottles, no money is offered to enhance recycling. It is simply not easy to find a place that accepts the used bulbs unless you get in a car and drive. I do not understand why small customer electronics 2-poles batteries are not recycled like soda bottles. The ballast circuit is only used to energize light bulbs. My 20 years old CFL takes 3 second before shinning. One new "instant shine" bulb burnt within six months.
As a amateur radio operator I can make use of these parts to build other projects such as a QRP transmitter! I agree with the waste of resources of these CFLs that are supposed save energy and "green house gases". The energy to build these components are polluting our air not to mention the landfill with mercury. All CFLs are twice as wasteful as any incandescent!
@poikaa3 Hi! I am glad to learn that you can use the circuit elements. In the Youtube nomadqqq's channel you will find a link to a Website that has lots of circuit diagrams for different brands of CFL bulbs. I had questions. They have answers.
Is there anything else that this complete circuit can be used for? As you will see in the diagrams different companies energize the bulb with different circuits. I assume that the circuit outputs are similar (or close enough). Thanks for the feedback!
@4iwilllive Hi! I have some CFL bulbs that look like regular light bulbs simply because they enclosed the CFL glass coil into a glass bulb. I have not seen a CFL bulb in the shape of a cone. Is it also enclosing a glass coil inside a glass cone? If it is a CFL bulb it has electronic ballast. You can try to separate the circuit from the glass by making sure that you do not break the glass. Even if you damage the circuit, you will not get hurt and will learn how to do a better job the next time.
@BloKK187 Thank you BloKK187. I try to speak slower when recording videos. My videos are made for people who do not already know it all. If you were patient enough to listen until the end of it, I did great. The goal is to not force people to view the video more than once just to verify what was said. I translate your comment to mean that you did not learn much from this video. Maybe you can teach me something about CFL. Seven months later, I am still here but my 24 years old son past away.
:) shouldnt sound like a dislike.. ive watched the whole video and i understand it. I am not a Electronic Specialist but i know a bit of this inverters. GOOD POINT the idea with the ONE VIEW - GET ALL
whats up with your son? is it what i think? my english isnt the best one :(
@BloKK187 I listened to the original audio track and decided to change it. I recorded the new audio track while watching the video and tried to say words that would go with the motion picture in a timely way. I used fewer words than were originally recorded and slowed down a lot. I was also holding the camera and a long stick that shook constantly, reinforcing the old man image. My son is in heaven now and I am still trying to understand. Thanks for replying & take care of yourself.
@BloKK187 Unlike you, I stay away from high voltage or very powerful magnets. It is because, I am always thinking about multiple procedures all the time. In other words, I get distracted thinking about too many things. Low voltage is forgiving. I am wise enough to know my limits. Maybe you could harvest and store electricity (by induction) from lightning, I would like to build a kite that is stable (no spinning) enough to carry a small wind turbine. The string will be made of wires. Cheap tower!
@BloKK187 I did not mean to suggest that you play with 40 Kilo volts. Since you are young and interested in high voltage, you could join a team of scientists who study lightning for the purpose of harvesting the power. Imagine a real grid of Franklin rods over whole countries waiting to capture the power from thunderstorms. I have no doubt that it will be done. The lightning grid could be independent from the power plants grid. That is my uneducated vision of the future. Have a good one!
@generatorblue And to you for continuing your electrical experiments, hopefully the world will change to be slightly more constructive rather than destructive someday.
Hello! Yes, there are some good parts in the CFL circuit. I like to use the toroids, which is the ferro-magnetic doughnut. I can see one in your video. I use them to make toroidal inductors, which are good for radio and the Joule Thief circuit, which I made a video about. You and I talked about a "battery juicer" (your term) a long time ago, so I think you might be interested in the Joule Thief. Take care.
@field16b Hi! After I posted the video, I looked around but could not find a single example of someone using traditional ballasts for something else. The juicer is still in my head. It is my longest kept secret. Without it, I will not be able to say that I can keep a secret. I would like to use at least half the circuit by knowing where to tap for practical outputs. I will be looking at the Joule thief. I am one lazy inventor; I try not to find what has already been built. Thanks for the feedb
@kevjay777 Hello! In the first audio track I called it a transformer. However, when I took a closer look at it, I could only see one coil. I am sure that someone will settle this one. I decided to take a guess based on the primary task of the ballast, which is to control the current. On the other hand, higher voltage could be needed to turn on the light bulb instantly. I have a lot to learn about this one. Thank you for your comment.
Yeah, normally with the newer "electronic" ballasted systems, both the bulb and the ballast goes. And sometimes this is even the case with the newer electronic ballasted systems that are in fixtures. This is why "preheat" magnetic ballasted cfl's and "preheat"/rapid start magnetic ballasted fixtures are much better. Alot of those are still in use. Also, when those electronic ballasts or components burn out, they literally "burn out." I experienced this many times. They are a fire hazard.
@suzukir123 Hi! I am not aware of people traditionally using ballasts for other than their intended purposes. I found videos showing homemade fluorescent ballast powering bulbs but I did not see any alternative uses for factory made ballasts. It looks like you have experienced catastrophic electronic ballast failure. I am positive that both the bulb and the ballast circuit can become defective. However, I doubt that they will fail together. Which one has the longest life (bulb or circuit)?
@suzukir123 OK! The truth is that I paid 49 cents for the new bulbs at "building 19" a place that sells items from other stores that go bankrupt or suffer natural catastrophes. When I discovered the electronic ballast inside the bulb, it felt like I found a treasure. I have enough of these bulbs to allow me to experiment with finding alternative uses for part of the circuit or for the whole thing. Other more knowledgeable people like you will find ways to use them before I do. You thought me!
@suzukir123 My experience with fluorescent lights is restricted to replacing bulbs and starters. In cases where new ballasts were needed, I replaced the whole fixture. All together my experience is in the range of basic maintenance. It is nothing like I saw in this Youtube video entitled: "Fluorescent Tube Burnout Extreme".

Only problem i have with cfl is the warmup time, the lights good when they get going.
Usualy its the circuit that fails,often through overheating.

These circuits are worth about $1. The reason bulbs burn out is because the circuits fail, not the bulbs.

Electronic ballasts in fixtures contain microchip ballasts
