Maintenance P roper maintenance is vital to efficient lighting. The amount of light produced decreases over time because of aging lamps and dirt on fixtures, lamps, and room surfaces. Never clean an incandescent bulb while it is turned on or it is hot. Replace lenses if they appear yellow. Clean or repaint rooms in your home every 2 to 3 years.
Dirt collects on surfaces, reducing the amount of light reflected.
Because fluorescent lights and some compact fluorescent lamps contain small amounts of hazardous chemicals, dispose of them with other household hazardous wastes such as batteries, solvents, and paints at your community's designated drop-off point. Optimize Energy Efficiency and Lighting Quality Simple changes in the lighting can improve lighting quality, make visual tasks easier, and save money on energy costs. Reduce light levels where there are no visual tasks. Provide necessary light for safety, security, and aesthetics. Provide adequate light levels for visual tasks.
