Having the stroll, sometimes leisurely, not always, along the landing, middle of night, we are guided with various glows from my studio plus the overhead smoke alarm built into the main ceiling. That is augmented byt the standbys on the computer, printer, the camera battery charger, the shredder and the Bose sound system.
Carole thinks we should close them all down as they are wasting leccie.

As soon as you turn all those locating lights off you will step on an upturned three pin plug or that piece of Lego that's been hiding for the last twenty years in your bare feet....

you only need a surge and all your devices are toast,
consider one of those security listening devices that switch a plugged in radio or light on ect when hear a noise.. when you move the light comes on
or even wiring in a pir to a led light,
amazing how much energy will save.

Blimey! I wasn't aware of that although it's never happened. Will investigate thanks
