Compact Fluorescent Lamp(CFL) is becoming popular day by day because of its ease of instillation and low power requirements.They have a fairly good life of about 2 to 2.5 years depending on use. I was having 4 dead CFLs and was wondering how I can recycle them. I got an idea to make Compact LED Lamp (CLL) from them. Read out my instructable to get to know how to make a CLL from dead CFL. Its easy, economic & fast. It took less than hour for me to make a CLL. So lets start.....
Step 1: What we need ?
We need the following material to make a CLL
1) Dead CFL(s)
2) Bright White LEDs having such size so that they can fit into the bore of tube of CFL.
3)Solder & Soldering Gun
4) A power supply (discussed in detail in notes).
5) Screwdriver, hammer, hacksaw, adhesive, adhesive tape, etc.
Step 2: Lets Get To The Work
Now, first of all we need to open the dead CFL and remove the ballast circuit in it. First remove the end connecting cap by screwdriver as shown in photos and disconnect wires. Then try to open the upper portion of the plastic assembly that holds the glass tube. It is anchored in the base plastic assembly that holds the ballast circuit. For some CFLs these two may be sealed with adhesive. Try to open them by screwdriver so that anchoring releases or simply use hacksaw to separate then as I used, Be careful while using hacksaw, cut it in circular fashion not from top to down. When you complete separate 3 parts of CFL, cut down wires connected to glass tube and remove ballast(choke) circuit from the middle part.
