I take it you were referring to me on the new bulb that makes more light with the same wattage.
The technology utilizes an infrared reflective coating. There is a modification that can be made to a 9011 irc bulb base that allows the bulb to be installed where a 9005 was originally. While current remains the same, a large percentage of heat energy is reflected back into the element. This is where the greater light output comes from.
Toshiba makes these bulbs. I'm not sure of any other manufacturers of this technology at this time.
