DENO LED Lighting

LED Strip Lux Target Calculator

Enter target illuminance, mounting height and profile transmittance, and the calculator works backwards to the lm/m the tape must deliver, the number of strip rows and the wattage that implies.

How the LED Strip Lux Target Calculator works

Enter target illuminance, mounting height and profile transmittance, and the calculator works backwards to the lm/m the tape must deliver, the number of strip rows and the wattage that implies.

The result also shows the efficacy needed to stay inside the energy class being specified, so a lighting level and an energy target are checked together.

  • Input: target lux, mounting height, transmittance.
  • Output: required lm/m, strip rows and W/m.
  • Efficacy check against the target energy class.

Frequently asked questions

How do I convert LED strip lumens to lux?

Lux is lumens arriving per square metre of the working plane. The calculator accounts for mounting height and profile losses to estimate the illuminance a given lm/m delivers.

How many LED strip rows do I need for a target lux level?

Enter the target illuminance and mounting height; the calculator returns the lm/m per row and the number of rows required.

Does an aluminium profile reduce LED strip output?

Yes. The diffuser transmits only part of the light, so transmittance is an input to the lux calculation.
