The American Bob Loblow once proposed a method by which a halogen lamp turns into a fluorescent lamp.
To implement your plan, you will need: light bulb, structural support, tools, hose clamp.
Unscrew the lamp as shown in the photographs, unscrewing the upper part together with the lamp and the lower part, remove the reflective foil. Then strip the wires 5 cm.
The housing for the new lamp will be an aluminum container. Make a hole in it for the base.
Follow the instructions in the pictures to mount the lamp. Holes will be required in order to pass wires and an angular support.
Connect the wires and install the bottom of the lamp.
Final Step: Replace the reflective foil.
Test your design - everything should work.
