" 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

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
