Re: [APD] lighting efficiency coefficient
We can but why would we?
There are lots of measurement techniques out there already.
The lux from a lamp (bulb and reflector assembly) is
already one of them. The problem is not a shortage of
measurement techniques, but a shortage of actual
measurements, a paucity of readily available data.
I guess the way I see it, new coins need to have new value
or else they're just counterfeits.
