Typical wattage range
5-15 W. Use a measured average when the device matters.
Lighting
LED light Runtime Estimate
LED lights are low-load essentials. Add each bulb or fixture if several will run during an outage.
Planning default
10 W at 100% duty cycle.
Confidence label
estimated. Treat the result as a planning estimate, not a lab measurement.
How to use this scenario
- Start with 10 W if you do not have a watt-meter reading yet.
- LED light is treated as a continuous load, so runtime is sensitive to the real wattage you enter.
- Keep at least a planning reserve because battery age, temperature, output path, and device settings can move the result.
Watch-outs
- The scenario wattage is an estimate. Measure the real load before relying on it for outage, travel, or critical planning.
