The fluorescent low-energy bulbs are terrible technology. The way forward is LEDs. The prices are coming down, they use very little energy and they last for yonks. And they come on straight away and you can get warm white. Clinging on to incandescent bulbs for old times' sake is highly irrational. Admittedly they have their uses, for example to make the artificial flames dance in me mum's electric fire, but, generally speaking, bulbs that convert electricity to mostly heat or which contain poisonous pollutants which are hard to dispose of safely when the bulbs are spent are nothing to get sentimental about.
