Are you recommending using a battery powered lamp in addition to the dyno powered one? If so in my mind that kind of defeats the purpose.
I think that MichaelW was saying that if the output wasn't enough for your needs/tastes, you could augment with battery powered lights. It's going to boil down to your environment, your own night vision, and your budget.
From my own research, a DIY using halogen would be brighter and cheaper. However, a blown halogen bulb will damage the light head if it isn't turned off or replaced pronto.
