60 vdc is still too high for the small number of diodes found in most lamps. Without switching, dc regulators (drivers) are extremely lossy, so we're back to switching regulators. Might as well use ac in the first place. The problem is that inherently the different type of light sources are not all equally suited for every application. It will be years before anyone can come up with a cost equivalent replacement for a 75 watt incandescent for a closet. Let the free market and customer needs, not government edicts and subsidies determine which lamp goes in which socket.

In addition, in the case of "white" LEDs, the phosphors also have a short persistence which helps to level any current caused flicker.

What part of a free market economy don't you understand? Without advertising exactly how do you expect customers to make informed, self-serving purchasing decisions? I would certainly agree that advertising needs to be honest. Oh--your 'free' universities--do the profs work for nothing over there? If not, who pays them?

I am pretty sure they have in Europe as they are very big on total energy consumption not just end user, they were and maybe still are also more concerned about what the load looks like for the energy provider i.e. the device P.F.

They mostly come from China and they are sold based on price so I think it is safe to conclude they are not.

There is no such thing as a totally free market, all markets are regulated to some degree. I do agree there is such a thing as over regulating a market and the incandescent might be one of those as I think it will probably die a natural death if left alone. Please also consider that almost all the people who supply your electricity are regulated.

Most of the military products I've designed had to operate at 100 degrees Celsius. Knowing where these products would be used, I would assume CFLs and LEDs would be designed in the same way. Are they?

My plasma TV burns 1750 Watts, and my government is worries about a few incandescent lamps?

Has anyone ever calculated how much energy/resources are consumed in the manufacture of ALL the components in an LED light? I wonder how much more efficient they really are when this is taken into account.
