Foot-candle grid verification for exterior lighting closeout

Foot Candle Grid helps a lighting commissioning tech or sitework foreman verify a permanent exterior lighting install against the approved photometric plan. Key the foot-candle readings from your handheld meter, station by station, and get minimum, average, maximum, and uniformity with a clear PASS or FAIL against your targets.

Works offline. No account. No backend.

The phone light sensor is screening only. Your handheld meter is the record. The approved plan is the design of record.

Common answers

Foot Candle Grid is an Android field tool from Anvilfield for parking lots, truck courts, data-center yards, walkways, docks, and property lines. The property-line trespass row compares boundary readings to the local cap you enter. The night-walk ledger keeps every area in one open list: pass, fail, not walked, and trespass fail.

Accuracy note: the grid math is deterministic. Pass and fail use full precision, not rounded display values. Verify targets against the approved plan, your handheld meter calibration, and the owner and AHJ sign-off.
