How can you save money on lighting?

• A. Install occupancy sensors, install reflectors on fixtures and harvest daylight.
• B. Install reflectors on fixtures
• C. Harvest daylight
• D. Use dimmers

Answer: (A)

Saving money on lighting comes from cutting how much you use and making the light you do use more efficient. Occupancy sensors automatically turn lights off when a space is empty, so lights aren’t left on unnecessarily. Reflectors on fixtures improve how effectively the light is distributed, letting you achieve the same brightness with fewer watts. Harvesting daylight brings in natural light during the day, reducing the need for electric lighting in those hours. Using all three together gives the biggest impact because you’re reducing usage, boosting efficiency, and taking advantage of natural light whenever available. The other options help in part but don’t address all aspects: reflectors alone don’t cut usage, daylight harvesting alone depends on daylight and won’t always cover nighttime needs, and dimmers reduce brightness only where compatible and don’t automatically reduce usage when spaces are unoccupied.
