Being conscious of how you use lighting is a no- or low-cost and immediate solution to reducing your utility bills. From turning off lights you are not using to changing lightbulbs, lighting is an important part of your overall energy usage.
What can you do about it?
Change out your lightbulbs.
Changing out your lightbulbs is a great low-cost solution to reducing your utility bills and save energy. New energy standards require lightbulbs to use 28% less energy than standard incandescent bulbs.
Lightbulb Types Compared
Add task lighting.
Provide “task” lighting (over desks, tool benches, craft tables, etc.) so that work and leisure activities can be done without illuminating entire rooms.
Place light fixtures appropriately.
When possible, place floor, table, and hanging lamps in the corner of a room rather than against a flat wall. Lamps in corners reflect light from two wall surfaces instead of one and, therefore, give more usable light.
Use dimmable lights and switches.
Where possible, consider using dimmable LED or compact fluorescent bulbs. Some compact fluorescent and LED bulbs can be used with dimmer switches. Check the package to see.
Choose lighter colors.
The reflectance of interior surfaces has an important bearing on lighting efficiency. In home decoration, choose lighter colors for walls, ceilings, floors, and furniture. Dark colors absorb light and require higher lamp wattage for a given level of illumination. Light-colored surfaces should be kept clean to keep reflectance levels high.
