PHYSIX OBSERVATION

A Japanese parts giant has started tearing down Chinese lamps to learn about cost, showing that the competitive focus has shifted from technology to cost control. China's supply chain has pushed lamp prices down to a new industry benchmark, forcing rivals to cut costs by 30% in three years. That is good for users, but if Japanese firms rely only on teardown and imitation, they may not keep up with the pace of iteration.
