you can do this without breaking the tube and if so then there is no risk of exposure to mercury. Can it work with ccfl lcd backlight? It means the circuit of most of the discarded CFL units never goes faulty, and can be recycled through some other means. 5 years ago Dismantle the faulty CFL bulb, repair of dead cfl, reuse of cfl, installation of cfl, first.
Ingestion is not an important route of acute exposure as almost no elemental mercury is absorbed through the gastrointestinal tract.". other side has two pair of wires 9four wires) these will be connected to the replacement type 20 Watt 24" Florescent Light bulb. A CFL uses vacuum pipe which is principle wise same to the strip lamps (commonly known as Tube light) . The Dr. Spock age has ruined childhood for a lot of kids. Somebody brought it in for show and tell, we all got to handle it, I thought it was very heavy for something so small. Please enter your email address. This post will discuss about What is CFL, How it works, Phase wise Circuit Explanation, Advantages and Disadvantages.
Just don't break the bulb. A CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime. Note the CFL module shold be mounted on an insulated plate.
In other words "CFLs are big failure". This could be why most asian children do so much better in school - they eat about 1000 times more fish than we do. I suspect it was cooked by the lamp heat, as 400V should be more than sufficient for the 325VDC (remember, 230VAC is RMS, peak will be higher). The components D3, R3, D2 and R1 work as a protection circuit and the rest as normal operation circuit. If the fuse is burnt, it may damage transistors and resistors also. Share it with us!
"Elemental mercury is toxic primarily through inhalation of mercury vapors. Thanks for this very informative instructable!
You can replace it with a 20 watt tube lamp. Of course children should obey their parents, but I think anyone can persuade their mom to let them do this by showing that by using safety equipment like gloves, goggles, and a ventilation fan or the open outdoors, there is nothing left to fear. The basic construction of a CFL consists a tube which is curved/spiraled to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of t… The CFL was initially designed to replace the incandescent lamp in terms of its compactness as well as energy efficiency. Did you make this project?
I know your orginal comment was two years ago but I just read it. Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal.

The damaged CFL can be reutilized using these two methods: Lets take example of a 23 Watt Philips CFL.
Mercury is odorless. She is also an active Web Designer. on Introduction, It works fine. on Step 3. as long as the glass doesn't break you should be ok. This process initiates the radiation of Mercury in Ultra violet form.
Any CFL of which bulb is defective, broken or has outlive its life is useful for this modification. Never again will I dispose of a CFL without recycling its electronics. If you are not able to do it, then go to an electrician and say him to check/replace it. Before everyone went all nutterbutters about Mercury, I used to play with liquid Mercury as a child. A T4 6W also lit up on this CFL. The tube portion of the CFL may be simply replaced with LEDs, and reused for getting the same illumination that your previous CFL used to give... well almost the same. Compact fluorescent lamp normally fails because of damage to some of its components like transistor, capacitor, diode, resistor or even the transformer. A very small voltage is generated by this changer, yet it is sufficient to run the lamp in ‘ON’ condition. Reply Actually, you get more mercury exposure by eating a tuna sandwich than by breaking the bulb. Reply You will see four points (solder) for each of the lamp side. Find a dead CFL unit, and very carefully open up the lid which holds the tube from the lower cup type enclosure.
"How much mercury is in fluorescent bulbs? Though, it has a higher purchase price than an incandescent lamp, it can save over five times its purchase price in electricity costs over the lamp’s lifetime. Try to Open The Dead Compact Fluorescent Lamp with the screw driver and move the glass tube and throw it we don't need it any more and remove this plastic part or break it and you will see the PCB and your FREE ELECTRONICS. In my experience these CFL ballasts accept wide range of lamps with light output variation. on Introduction.

If the cap is bulging, don't use it. You can seal it by using insulation tape or Feviquick or Plaster of Paris. The following information on mercury content and mercury use is taken from a fact sheet on mercury use in lighting from the Northeast Waste Management Officials' Association (NEWMOA) . CAUTIONARY NOTE : DO NOT OPEN THOSE CFLs WHICH HAVE BEEN USED WITHIN TWO HOURS. Reuse the CFL PCB as a Ballast (Choke) for another Tube light.
Note and precautions: CFL's contain mercury which is hazardous material, so it should be handled accordingly Most CFL lamps, electronic circuits are working perfect and are still useable, only the bulb goes defective. Remove the old CFL cap and check the inner circuit. I am already using 40 watts tube with 23w energy saver's circuit BUT it is dim than 40 watt ballast, Reply Reply
Disassemble the CFL as shown in the picture. A CFL works in an energy efficient way. Mercury is also used as a preservative in vaccines.
