Re: Apologies, typo here
Can we even accurately measure it given the signal is mixed with every other electrical device in the home? Sure, we can put meters on individual appliances and work it out but is there any simple way to say "X" is lighting. Does it get more complicated given the ambient light cast off by the myriad devices in our lives like computer and TV screens and the dozens of other devices with luminous displays even if it's just a green led on the router, a red one on the switch and a blue one on the modem? At some point we're just picking, err, nits.
