[Bob] had a couple of bright, 12V halogen spotlights in his hallway that didn’t get much use. Rather than toss them out or leave them sitting idle, he decided to replace the bright bulbs with dimmer LEDs that he could keep lit through the night. He opened up the spotlights, removing the bulbs and the built in mirrors b...
