Length × W/m, PSU headroom, lumens

Quick Answer

LED Strip Calculator: Length × W/m, PSU headroom, lumens. LED Strip Calculator uses standard everyday life formulas to compute accurate results instantly.

Strip parameters

m
Recommended PSU130 W
Total strip power100 W
Total luminous flux9,500 lm
Current at 12V8.3 A
Daily use (8 h)0.80 kWh

How it works

  1. 1Power = 10 m × 10 W/m = 100 W
  2. 2Flux = 10 m × 950 lm/m = 9,500 lm
  3. 3PSU = power × 1.3 = 130 W
  4. 412V current = 100 ÷ 12 = 8.3 A

Voltage drop: keep 12V runs within ~5 m and 24V within ~10 m; split long runs into segments powered from both ends or choose 24V.

PSU headroom of 20-30% is standard practice — drivers run hot at full load, which shortens both the PSU and strip lifespan.

Heat kills LEDs: above ~40 °C ambient, rated life can drop sharply; aluminum channels act as heat sinks and are strongly advised for main lighting.

Choose constant-current flicker-free drivers (no visible flicker on phone camera) and check the cut-unit spacing before cutting.
