In the spotlights, the weakest part is the halogen lamp, the replacement of which is not at all cost-effective. To give the projector a new life, you need to replace the light source with a diode module in it.
For crafts, you will need a spotlight body, diodes and a boost module up to 35 Volts. The diode assembly is mounted on the cooling radiator with glue, then the boost module is connected. The result is a searchlight that runs on battery or power bank.
The finishing touch is the creation of the bracket for the spotlight and its painting. At low cost with your own hands, a very useful thing was created for work in the absence of stationary power sources.
