How LED Strip Power works
This worksheet evaluates P = length × W/m. LED Strip Power uses Strip length, Power per meter to report Strip power.
With the loaded values, strip power evaluates to 115.20 W. Hold the remaining entries steady while testing an uncertain input.
Inputs for LED Strip Power
Strip length and Power per meter belong to LED Strip Power. Keep source units with strip length.
The sample case is a worked example, not a design target.
- Strip length
- Example entry: 8 m.
- Power per meter
- Example entry: 14.4 W/m.
Reading the LED Strip Power result
This output represents LED Strip Power. Voltage loss belongs in the separate LED Strip Voltage Loss worksheet.
Compare the output with equipment limits and the applicable design margins.
Measurement and units
Photometric results depend on fixture distribution, reflectance, mounting, maintenance, and the measured task plane. Check prefixes on strip length.
Do not compare cases built from different unit prefixes or measurement locations. For wall-plug efficiency, use Lighting Wall-Plug Efficiency Calculator.
Limits of this calculation
Long runs may need power injection.
Only the stated inputs participate in this simplified model. Unentered effects remain outside LED Strip Power.
Questions about LED Strip Power
What does LED Strip Power calculate?
LED Strip Power reports strip power.
Can Strip length be zero?
For LED Strip Power, measure any zero strip length directly.
Why can strip power differ from measurement?
Long runs may need power injection. Recheck strip length.
