The walker should have turned away. I don't see a reason for pedestrians to have bright lights. They don't need the visibility as much.

While I understand your complaint, I feel that a bright light is simply a good precaution. I biked approx 11 miles to high school for 2 years in LA. I wore screaming yellow and had a bike light that was equivalent of a 40 watt halogen on its lowest setting. Despite all that, I was still somehow invisible to many cars. I'm not saying that you don't have a valid point, but that there are valid reasons for ridiculously bright lights.
