On Friday I visited a friend who had strings of decorative LEDs in the living room. Because of the increases in electricity prices she was running them from AA cells. Bill

That old chestnut...... Does she not realise that electricity is used to make the electrolyte, the anode, the cathode, the seperator, print a colour label, create all the packaging and of course the electricity needed to recycle the cells at EOL?
Its *still* cheaper to power with electricity than it is by battery
In addition, electrochemistry is not a 100% efficient conversion.
... about the most expensive source of electricity available. (Except for nuclear batteries)
Clearly she doesn’t.

Makes good sense if she doesn't pay for the AAs.
To save using the 15W wall or 15W ceiling lights in my main living room I purchased a mini up-lighter that is fitted with a 1W GU10 LED mains bulb. It provides a surprising good amount of light. I can just about read a book with the light with some eye strain :). I do however have (off) white walls and ceiling.
I see, so that makes sense then? Perhaps AAs are bought by a different budget. She should be part of the Government, they are always trying to make savings by moving the problem to another department. Brian
