Hi everyone:
Has anybody measured power output of old and new dynamo flashlights? any comparison table? any kind of comparison data? just curious...because over the years different types of permanent magnets materials were used increasing efficiency (alnico, ceramic 5, ceramic 8, neodimium, etc.).
Thanks! Vladman
