Three recessed ceiling light fixtures flood the fireplace in our family room. Sometime after we moved in, the dimmer switch that controls the lights stopped functioning properly. It turned the lights on and off, but did not dim them. We were not concerned with our inability to dim the lights and affect the mood of the room because the light bulbs' brightness at that time was not an issue. Recently, we started replacing our incandascent light bulbs with compact fluorescent light bulbs (CFL). The CFL bulbs we purchased have a higher lumen output than the incandescents, resulting in a brighter light. It was now time to solve our dimming problem.
