Had it been dark and you'd had lights on
you'd have noticed a reduction in brightness. Probably.

Absolutely.

I sit up late with the cat and a lager and watch old films on the telly
with houselghts dim and surround sound through a separate unit. (On
Saturdays I have some cheesy biscuits - that's living all right!)

My lights, (overhead supplied) are always dimming, but the telly, HDD
player, and audio unit don't give a damn.

Neither does my PC if on, or anything else that I can see.
