- Turn off non-essential and decorative lighting, especially in unoccupied areas.
- Replace flickering, dim and burned-out lamps.
- Clean fixtures and diffusers (at least annually).
- Color-code or mark light switches and circuit breakers that can be turned off when not needed.
- Use task lighting to directly illuminate work areas.
- Lower the height of light fixtures if possible to increase usable light.
- Replace burned out lamps with lower wattage energy-saving lamps wherever possible.
- Replace incandescent lighting systems with compact fluorescent and/or high-intensity discharge fixtures.
- Replace existing T12 fluorescent lighting systems with energy-efficient T8 lighting and electronic ballasts.
- Install more efficient security and parking lot lighting. High-pressure sodium fixtures are more efficient than metal halide, mercury vapor, fluorescent, or incandescent fixtures.
- Install time clocks or photoelectric cells to control exterior lighting, advertising sign lighting, and some interior lighting.
- Paint dark walls and ceilings with lighter colors to maximize the effect of existing light sources.
- Maximize natural lighting by installing skylights or windows.
- Install occupancy sensors or twist timers where appropriate to lower energy use such as in offices, stairwells, copy rooms, storage rooms and restrooms.
- Schedule janitorial services during the day, or use a minimum number of lights when cleaning at night. Color-code switches that should remain off when crews are cleaning.
- Implement a group re-lamping schedule, and re-lamp at 70% of rated lamp life.
- Trim bushes and trees away from outdoor lighting to maximize illumination and prevent shadows.
