Porch, pathway and security lights may have different schedules even when they are on the same property. This worksheet helps a Florida resident estimate the electricity for the lights they control. It distinguishes household-owned fixtures from a separately billed utility lighting service and does not treat reducing safety lighting as an automatic recommendation. Landscape lights added for an event and a permanent security fixture have different purposes and schedules. Separate those groups so an occasional event does not become an assumed year-round increase in the property’s lighting allowance.
Measure the load that matters
Count fixtures by wattage and operating pattern. A dusk sensor, timer and motion sensor produce different hours, so use observations or an explicitly labeled estimate. Check whether a bill line is a service charge for a provider-owned fixture; that arrangement may not change when household electricity consumption changes. For fixture wattage, match actual installed products and their supported settings. For operating hours, distinguish timed operation from intermittent sensor activation. For utility lighting service, separate a contracted service line from metered household use. For controls and installation, quote replacement controls and professional labor separately.
Build comparable operating scenarios
Calculate each fixture group separately before totaling the month. Compare replacement bulbs only when they are suitable for the existing equipment and required lighting function. Include any installation or control costs separately, and do not assume that a lower-wattage choice gives the same coverage or meets site requirements.
Check the result before changing equipment
Keep a simple fixture map and schedule with the calculation. Review sensor behavior and operating hours during an ordinary period, using professional help where needed for equipment access or changes. Compare the expected electricity amount with the type of lighting charge actually shown on the provider’s statement.
Build your own itemized estimate
Use this topic-specific checklist to collect the actual scope and written amounts. Keep the quote date beside each figure; an unknown charge should stay blank until checked.
| Cost or decision | What to verify | Your amount / date |
