Pro Tips for Lighting Energy Cost
- LED lighting uses significantly less energy than incandescent or even CFL for the same brightness — factor this into any lighting upgrade decision.
- Multiply by usage period (daily, monthly, annual) for the relevant total cost figure.
Common Lighting Energy Cost Mistakes to Avoid
- Comparing lighting types by wattage alone without accounting for actual usage hours, which also determines real energy cost.
