Slice each banana in half lengthwise, then cut them in half. Lay out one lumpia wrapper on clean surface. Roll banana in sugar and place on wrapper near edge. Roll banana in wrapper once, then turn in edges and keep rolling. Seal the opposite edge with water.
Deep fry at 350 degrees until golden brown, about 3-5 minutes on each side. Drain on paper towels.
