The basics of lighting upgrades
Average lighting project price range
Varies depending on the type of light bulbs used and the size of the project.
Average savings
Again, varies depending on the type of light bulbs used and the size of the project. In general:
Compact fluorescent lamps (CFLs) are 3.5 times more efficient than incandescent light bulbs.
Light emitting diode (LED) bulbs are 4 times more efficient than incandescent light bulbs.
Level of difficulty (to implement)
Easy -- upgrading lighting simply requires replacing current light bulbs with more energy-efficient ones.
Is this project for me?
If you want to see if a lighting project is right for your home or organization, it’s simple to estimate the savings.
1. Take an inventory of the light bulbs that you plan on replacing.
2. Use a basic multiplier. In general, CFLs are 3.5 times more efficient and LED bulbs are 4 times more efficient than incandescent light bulbs.
