How to Use Burnt Compact Florescent Light Circuit Module


Compact florescent lights (CFL) are becoming increasingly popular with people who want to save a little money on their power bills. When a CFL goes out, it is not down for the count; the circuit module in the CFL is still usable. Follow these steps to remove and utilize a CFL circuit module.

Things You'll Need

  • Hacksaw
  • Flathead screwdriver
  • CFL
  • Hot glue gun
  • Wiring
  • Plexiglas
  • 18 to 20 watt florescent lamp terminal blocks
  • Begin the process. There is a seam where the CFL can by pried apart. This seam may be securely fitted, glued or even welded in place. Sometimes you may be able to use a flathead screwdriver to separate this, but it is easier to use a hacksaw and cut the bulb slightly.

  • Separate the bulb parts. Now that you have a small cut in the bulb, use the flathead screwdriver to separate as needed. When the seam is weak enough, twist the two parts apart.

  • Remove the circuit module.

  • Look at the picture above and you will see wires coming from the CFL circuit module. The wires to the left go to your power supply; the two pairs of wires on the right are your positive and negative wires.

  • Connect module to an 18 to 20 watt florescent lamp. Be sure to use an insulated plate (such as Plexiglas) and attach the circuit module to it (possibly with a hot glue gun).

  • Connect wires to the power source and the negative and positive poles using terminal blocks as midway points (if needed).

Tips & Warnings

  • Do this only if you have experience working with electrical or electronic equipment. Do not break the tube; it contains phosphorous and mercury, which are toxic.
