"If you are worried about all of the 500w floodlights....."
I'm not particularly worried; I don't illuminate my house all night and the one halogen light I do have (sensor controlled, has the minimum sized tube).
I am just struck by a government who will happily introduce a law making my lighting inefficient and costly, yet ignore one of the great power consumers - uncontrolled vanity lighting.
All Fluorescent bulbs are undimmable and produce a cold, harsh, and to my mind, flat, characterless light, leaving the impression of an income tax office or an unemployment exchange.
They can also exacerbate existing health problems; a friend is epileptic and one of the triggers is fluorescent lighting.
