Actually, incorrect. The efficiency of any given halogen varies with voltage. At a higher voltage, you get more lumens per Watt. You also get higher temperatures and much shorter life. That's why Sylvania Silverstars burn out faster than conventional halogens. I bet the EcoBright use the same principle, resulting in a bulb with shorter life, hotter filament temperature, lower power draw, and just as much light as a regular halogen.

And yes, I know these bulbs don't actually step up the voltage fed to them. But a shorter filament accomplishes pretty much the same thing, in terms of longevity and efficiency.
