here a picture of a conventional light-bulb in comparison with a OSRAM Decostar IRC:..
There seems to be a big difference between conventional (brand and model?) and IRC halogen. Overvoltage means much more light, we noticed this also in our tests:

14,4 V: http://www.kolumbus.fi/~z606623/DIY/Lampputesti/IMG_0790.jpg
16 v: http://www.kolumbus.fi/~z606623/DIY/Lampputesti/IMG_0792.jpg

Of course the lifetime of the bulb will degrease with overvoltage, but how high voltages can be used before the burning time becomes too short for cycling use? It depends...

Tobbi, your setup looks great, especially the battery (voltmeter looks really cool ). And very informative sites too.
