However the energy secretary, Steven Chu, has argued that the 2007 law does not amount to a blanket ban on all incandescent bulbs. But it does require those bulbs to be more efficient. \”These standards do not ban incandescent bulbs,\” Chu told a conference call with reporters. \”You\’re still going to be able to buy halogen incandescent bulbs. They\’ll look exactly like the ones you\’re used to. They can dim. They cut out instantly. They look and feel the same.\”
Look, yes, I know, you\’ve a Nobel and I don\’t.
However, I supply the lighting industry and you don\’t.
Halogens are not the same as incandescents. The latter, the light comes from that piece of tungsten heating up in a vacuum. The former, there\’s a gas in the bulb (that\’s the halogen bit, see?) which is then heated by the tungsten wire.
Different technology. And, as you should also know, the gas in the halogens is actually mercury. The halogens themselves (EuI3, ScI3 and the like) are dopants in miniscule amounts.
The really important point about this (apart from the fact that people using more halogens is just great for me) is that that mixture of halogens and mercury costs more than the entire incandescent bulb does to manufacture.
So you\’re still insisting that people go off and use a more expensive tehnology to the detriment of their pocket books.
Update: And I am of course entirely confusing halogen bulbs with metal halide bulbs. Silly Timmy.
