Kinda long isn't it? Aero-Tech used to make these Eternity brand bulbs a while ago, they are kinda rare and I have seen only one before finding this first one for my collection. 69w of power with a light output barely brighter than a 40w standard incandescent and a very orange color!
When incandescent lamps are underdriven, they are dimmer for more power. So if you want more life in a lamp you will be using more energy for less light. If you want incandescent lamps to be MORE efficient you will need to overdrive the voltage, which makes the incandescent lamp brighter for less wattage, BUT you get reduced lifetime. That's how incandescent lamps kind of work.. Right? xD
Are they long life incandescent bulbs? I know a 5000 hour 130v bulb will last 14000 hours.
Actually if you underdrive incandescent lamps the wattage will go down but lumens will go down more, making the filament burn cooler and longer lasting.

The 130 volt lamp will last about 12,000 hours on 120 volt....
