On some lights the standlight uses different LEDs than the main beam. On those lights, if you are not moving the main beam would not be lit when you "stand in front of the bike with the light on full" because you need to be rolling for the dynohub to power the light.
Instead I always try to set my beam so that it just barely is high enough to show in the taillight reflectors on the parked cars in front of me as I ride.
