I am not sure where I am going on the issue of back-up lighting. But I must do something soon, partly because in the last power cut here I had to deal with another resident suffering a major panic attack (and although I didn't see it, nearly causing a disaster by putting the largest candle we had on the top of the lit wood burning stove "to give light").
In the mean time I am playing around with how to use LED lights to reduce the power consumption. One surprise what at the other half accept a 1 W LED bulb in the bedroom bed-side lamp. It is a clear white light and provides enough light for her to read at night, and for us to find any clothes etc around the room (although not good enough for hunting for dropped earrings etc).
I would recommend that people go for 'day light' lighting - in does not have the yellow glow that we are used to, but the human eye seems to be more adapt to the wave lengths it uses so it is easier to see things even if the light is not so powerful.
The other thing I am trying out is using a string of LED lights (sold as Christmas tree decorations) as background lighting for the living room. It gives a festive appearance and enough light (total power use 7W) to navigate safely around the room. I will have to try this on some unheated stairways (where CFT bulbs take too long to warm up in the cold of winter). The advantage of buying Christmas tree lights is that they are so much cheaper than the specialist designs for LED stair lighting.
One trouble I am having with LED is that it is best either as a spotlight or as a string of lights, and this house is wired for the old fashioned bulbs, where one bulb gives general light to the whole room. So I need to see what will fit without having to rewire the whole place.
We should teach our children the 4-Rs: Reduce, Reuse, Recycle and Rejoice.
