I have two LUX apps on my phone
How they compare to the one in the link...IDK
What I did was use them to compare readings between fluorescent ceiling lamps..And LED ceiling lamps
Side by side readings turning the lamps on and off , phone at waist height beneath fixture
No way for me to calibrate to a known source , to make lux to watt readings
I like the idea...read the lux at the panel..then record the watts from the controller out Turnigy meter
The next time I get out the telescopic ladder and get on the roof
I might do that
But it will only be relative , because I don't have a dedicated calibrated lux metre
