Do I have to use all fluorescent lights?
Kitchens need to have 50% of the watts of lighting be high efficacy(flourescent or LED). Bathrooms, laundry rooms, utility rooms and garages must have all fluorescent lighting or have the lighting controlled by a vacancy sensor. All other rooms may have all incandescent lighting when controlled by a manual dimmer. Outdoor lighting mounted to the building must be high efficacy or be controlled by a motion sensor and timer. Call us to discuss these requirements if you wish.
