What size power station do I need for LED light?
LED light
Default appliance profile before model-specific measurements.
For the supplied profile, the 10 W LED light uses about 60 Wh per day (6 hours at a 100% duty cycle). Applying the stated inverter-efficiency, usable-capacity and reserve assumptions produces a conservative one-day target of about 87 Wh nominal capacity.
The power station should support at least 10 W of continuous output and 10 W of startup demand. Actual consumption may vary by appliance model, settings and conditions; no model-specific measurement is supplied.
- Minimum sizing: Use about 87 Wh nominal capacity for one conservative day of this load.
- Example capacity: The supplied profile estimates 300 Wh as about 4 default-profile days, or 23.8 hours at continuous draw.
- Before buying: Include other simultaneous household loads when sizing a complete backup setup; a plug-in power meter or manufacturer energy label is preferable when available.
Using the default load profile, led light consumes about 60 Wh/day. A conservative one-day battery target is about 87 Wh nominal capacity, while the inverter should cover at least 10 W of startup demand.
Assumptions behind the calculation
- Running draw: 10 W
- Startup/surge: 10 W
- Default use: 6 h/day
- Duty cycle: 100%
- Usage uncertainty: ±10% before model-specific measurements
Actual energy use varies by appliance model, ambient conditions, settings and load. A plug-in power meter or manufacturer energy label is preferable when available.
Runtime by battery size
| Station capacity | Continuous-draw runtime | Default usage profile |
|---|---|---|
| 300 Wh | 23.8 h at continuous draw | 4 default-profile days |
| 500 Wh | 39.6 h at continuous draw | 6.6 default-profile days |
| 1000 Wh | 79.2 h at continuous draw | 13.2 default-profile days |
| 1500 Wh | 118.8 h at continuous draw | 19.8 default-profile days |
| 2000 Wh | 158.4 h at continuous draw | 26.4 default-profile days |
| 3000 Wh | 237.6 h at continuous draw | 39.6 default-profile days |
Use your actual household loads
The calculator combines this appliance with refrigerators, networking, pumps, medical equipment and other essentials so simultaneous wattage and motor startup are not ignored.
