Well said, cyfr. And, while I am not an expert in the field, it would not suprise me to learn that it would be possible to build solar cells, ones that work better with the light spectrum from LE bulbs, for use in calculators and the like.
My area is finance, and I've done the calculations (based on US electricity prices) and the LE bulbs make financial sense - and will make even more sense as the price of electricity increases. I would expect that electricity in the UK probably costs more than it does here (based on the price of gasoline, another energy source), so LE bulbs probalby make even more sense over there. Also, I really like the fact that the LE bulbs burn out less frequently, in part because I like the convenience and set some value on my own time.
