STEP 0: Pre-Calculation Summary
Formula Used
Incident Luminous Flux = Reflected Luminous Flux/Reflection Factor
Φi = Φr/ρ
This formula uses 3 Variables
Variables Used
Incident Luminous Flux - (Measured in Lumen) - Incident luminous flux refers to the total amount of visible light energy emitted or received by a surface per unit time.
Reflected Luminous Flux - Reflected Luminous Flux is defined as is a measure of the power of reflected visible light produced by a light source or light fitting.
Reflection Factor - Reflection Factor is the ratio of the total amount of radiation, as of light, reflected by surface to total amount of radiation incident on surface.
STEP 1: Convert Input(s) to Base Unit
Reflected Luminous Flux: 26.624 --> No Conversion Required
Reflection Factor: 10.4 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Φi = Φr/ρ --> 26.624/10.4
Evaluating ... ...
Φi = 2.56
STEP 3: Convert Result to Output's Unit
2.56 Lumen --> No Conversion Required
FINAL ANSWER
2.56 Lumen <-- Incident Luminous Flux

How many lumens is a Lux?

The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter.
