Just trying to understand but you are in favor of continuing to produce a light bulb with 10% efficiency?
There's no reason in this day and age for incandescent light bulbs to exist anymore.
The man who saved the lightbulb

A modern day Edison has a bright idea: a way to keep the incandescent bulb burning brightly, despite a government law set to go into effect New Year’s Day that effectively outlaws the most commonly used lightbulbs.
Most bulbs, that is. Not those made by lightbulb savior Larry Birnbaum.
“When the government decided to ban incandescent lightbulbs, they left a loophole in the law. An opening,” Birnbaum told FoxNews.com. “What that was was rough service.”
A “rough service” bulb is, in Birnbaum’s words, a bulb that can take a beating, one meant for industrial purposes -- imagine a lightbulb on a subway car, built to survive the jostling and vibrations of the daily commute. But despite their intended use, they work just like normal bulbs: Consumers can buy them and screw them into any ordinary lamp socket.
Newcandescents are available at a retail store in South Hackensack and in a variety of supermarket chains, including King Kullen, Gristedes, Pioneer and more. They’re also online: Bright Lights Inc., a retailer that sells Newcandescent bulbs, lists a two pack for $2.88, or $1.44 apiece, CEO Paul Veen told FoxNews.com. His company caters to the south, distributing bulbs across Alabama, North Carolina, Tennessee and more.
It is so silly to ban lightbulbs when LED bulb development is hitting efficiency at several times of CFL's, LED bulb pricing is coming down as well, you can get a 40watt OUTPUT for as little as 3 or 4 bucks and that bulb will last you tens of thousands of hours WITHOUT the mercury that CFL's contain.
I know some cities around where I live where they MANDATE you use CFL's in bathrooms when you remodel or rebuild a house. Just complete idiocy.
Gotta love the nanny state.
You need to look at long term cost including the energy consumption, not just the up-front per unit price of a quality LED replacement for a filament lamp. In my earlier example a LED lamp works out at about 80% or more overall saving per annum for lighting and, in fact, you'd still be ahead even if you had to replace all the LEDs every year and that's what will sell them above all other factors. Even if the LEDs were $50 each you'd still be better off and mass production has them now at a tiny fraction of that.
I do pity those who fell for the 'modern' dichroic downlight craze (the 12V 50W ones in particular) because they effectively as much as tripled their lighting energy consumption and now have no cheap or simple solution to get the costs down again. Sure you can get 12V LED lamps that plug straight into the recessed sockets and only take 3 or 4 watts but the 50W SMPS power supplies will not start up without near full 50W load on them which I believe is a designed-in safety factor.
The life expectancy of LEDs is excellent but they tend to be only talking about the actual LED itself which can last 100000 hours or more. The electronics in the lamp base are not so long-lived though and might only last less than 20000 hours, the lifetime being inversely proportional to operating temperature so even LEDs (in recessed or enclosed fittings) may very well not last as long as the label claims. Manufacturers are being forced to make honest claims these days and the Philips LEDs I have here quote a lifetime of 'up to' 15000 hours provided they're not used in enclosed fixtures IE they need good ventilation or they'll suffer an early demise.
