i looked at all the possibilities for the location of the lights last night and also put some thought into what i am trying to achieve...

one light will go into the kitchen
the passage where the DB is located...handy when the light go off to find the trip switch
the lounge and the main bathroom/toilet

i am just gona hook the lights onto a hilti pin so i can just unhook them and move them around.

i am also wondering if using the solar panel is not a better idea...then it is totally independant of the house electricity...and can come on everynight with the daynight/switch supplied and go off in the morning...the running cost will be a new battery every 1 - 2 years...
