Lamp life threshold approaching.

Cumulative burn hours on a circuit approach the lamps' rated life — failures will start to cluster, and the burn-hour record is the evidence for an efficiency rebate.

Related metric: burn_hours
Trigger: cumulative_burn_hours approaching lamp_rated_life
Value drivers: Asset lifespan Avoided truck rolls
Preconditions: Per-circuit on/off state accumulated over time; lamp type + rated life on file.
Human role: Plans the proactive group relamp and assembles the rebate evidence.
Action plan: (1) Confirm cumulative burn hours are approaching the lamps' rated life for the circuit. (2) Plan a proactive group relamp before failures cluster — one scheduled visit instead of repeat emergency lamp-out calls. (3) Where an LED-retrofit rebate is conditional on minimum burn hours, export the cumulative burn-hour record as proof of the condition.
Escalation: (1) Burn hours far above the space band with no operational reason -> a stuck-on circuit or a schedule gap (cross-check Schedule Compliance) is wasting both energy and lamp life.
Prevention: (1) Track cumulative burn hours per circuit against rated life so relamps are planned, not reactive.
