Use compact fluorescent reflector flood lamps (cfl) in your recessed lighting for energy savings of up to 80%. They also cut down on the heat which could also help with the A/C bills in the summer.
Example: Use a 15 Watt Energy Wiser Fluorescent in place of a 60 watt incandescent for over a 80% savings on your energy costs.
Not used with fixtures controlled by a dimmer, electronic timer or photocell
