we'll show you how to turn an old CFL lamp into a power source. This project is perfect for people who have lots of old lamps lying around and want to turn them into useful appliances.
This project is easy to make and only requires a few tools and a little imagination. By following our steps, you will be able to turn your old CFL lamp into a powerful power supply that you can use in your home or office. So be sure to watch our video and learn how to turn an old CFL lamp into a power source!
Many chandeliers, ceiling lights or recessed spotlights are equipped with halogen bulbs of the G4 or MR16 type. These installations work with halogen-type bulbs, powered by an electronic transformer providing a current between 11 and 18 Volts.
Why replace a halogen spotlight with a 12V LED?
In order to save money, to gain in life or simply to replace a defective bulb, it is interesting to replace the very energy-consuming 12V halogen bulbs with a G4 LED bulb or MR16 LED bulb with equivalent light but a consumption 7 to 10 times lesser.
How to replace a 12V halogen spotlight with an LED?
It is relatively simple and quick to make this replacement, however you will need simple notions of electricity:
Warning: it is imperative to cut off the electricity before touching the installation.
Equipment required: screwdriver, cutting pliers, wire stripper, electrical connection terminal, MR16 socket, LED power supply.
To find the transformer, it is sometimes necessary to pull lightly on the wires in order to make it appear in the recessed hole.
The transformer is an electronic block that transforms the AC220V input current into AC12V current. Generally, these transformers operate in the 20W – 60W range and do not deliver a stable current for an LED. In order to ensure a good lifespan for the LED, it is necessary to replace this transformer with a stabilized LED power supply. If it is not changed, the bulbs may flicker, light unevenly and burn out quickly.
4. Unplug the old transformer
Once the transformer has been identified, you must cut or disconnect the 220V input (brown and blue wire in general), cut or disconnect the 12V output (red wire V+, black wire V-).
Replacing 12V halogens with LEDs: case of the EGLO chandelier.
In this new example, we are going to change the power supply of an EGLO type chandelier sold by LEROY MERLIN, this chandelier has the particularity of having a set of RGB LEDs for decoration and 9 12V 20W halogen bulbs for lighting at properly speaking. The RGB LEDs are powered by a 6W power supply and the halogens by an electronic power supply. The set is remote controlled so that you can choose the number of 5 or 9 bulbs lit at the same time.
Why change the power supply to install LEDs?
The decorative LEDs are powered by a 6W 12 Volt DC power supply (which will not be changed). The halogens are powered by an 11.5V AC electronic power supply which operates in the 50 – 210W power range. In normal operation, halogen consumption is therefore 100W (5 bulbs on) or 180W (9 bulbs on). By replacing these bulbs with LEDs whose consumption is 2.2W, the consumption will be 11W for 5 bulbs and 19.8W for 9. We are therefore outside the operating range of the electronic power supply of origin that it is necessary to change to ensure the correct operation of the LEDs.
If the power supply is not changed, the bulbs will flicker, light unevenly and burn out quickly because they are not powered properly.
How to change the diet?
Materials needed: a Phillips screwdriver, a flat screwdriver, wire strippers (or a cutter), a new power supply and a domino (or Wago-type quick connector).
Time: 30min for one person
1) Disassemble the chandelier after turning off the power
2) Identify the transformer to be changed, the input, the output and the other elements. In the case of a simple power supply without a controller, there will only be a 220V electrical input and a 12V output (the most common and simplest case).
3) Cut the 220 Volt electrical input wire arriving at the transformer (yellow arrow) and the AC11.5V output wires (two output wires + and -). Once this is done, you can remove the old transformer.
Now we will connect the new DC12V power supply instead of the electronic power supply. In this case, the maximum power used by the bulbs is 9*2.2=19.8W so we opted for
a transformer with a maximum load of 30W.
4) Cut and strip the input and output wires of the new power supply
5) Connect the 220V electrical input of the power supply to your electrical input using a domino or quick connector
6) Connect the red (+) and black (-) cables at the output of the power supply. In the case of the EGLO, the red wire must be connected to the controller and the black wire directly to the bulbs. If your chandelier does not have a controller, simply connect the + and – wires directly to the bulbs.
7) Screw the power supply onto its support and reconnect the chandelier
There you go, the operation takes about 30 minutes and allows you to save 85% of electricity while guaranteeing long-life lighting thanks to LED technology.
