Nice touch Tom with the meter.
Things you can't do with your android :)
I could not find luminosity app, but found multi-meter app with that instrument.
So just for the sake of it, I compared the 25 LED lamp in my bedroom with dining room chandelier, that is having 18 incandescent light bulbs at I think 60w each. So both 25W LED and 1080w incandescent give me the same 6000 lux at table level.
The main difference is that incandescent chandelier give me nice coverage in whole room, while LED drops the exposure drastically once you are out of the main beam.
I did play with it a bit more and wonder about accuracy as the readout jumps from 20 to 6000 with slight hand movement measuring daylight in the garden. Also seems 6380lux is end of the scale on my android.
