" electronic bulbs?especially fluorescents?require a lot of resources to manufacture" The incandescent equivalent of 1 CFL is 5 to 10 incandescents, depending on whether they are 1000 or 2000hr life. This is a lot of resources to manufacture, and glass has significant energy cost . You also have to go change them,go purchase them and go dispose/recycle them etc. The extra Hg ,radioactive thorium etc that rains down all over the country from burning 4x more fuel can't be cleaned up at all. Our children have to go fight foreign wars over oil and we subsidize foreign oil dictators.

I can't use CFLs on my bench when testing low-level analog circuits---all so far generate way too much electrical noise.

Electronic bulbs last a lot longer, which is a significant benefit for lamps that are hard to access. There are trillions of standard lamp sockets worldwide; when electronic bulbs reach a sweet spot of price and color quality they will start to take over. Dimmability will be nice, and expand the market further. But as Bill says, there will always be niche markets for incandescents, just as there are still niche market for vacuum tubes.

You can add that incandecent bulbs are very usefull loads in testing large power suplies. They are cheap and deffinitely readily available. I sometimes still use 500,1000,and 2000 watt bulbs. ( found in ancient theater lighting) Bill Scheinman

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
