Why a Headlamp Fails at Precision Electronics Work

A rebuilt server, a headlamp on a dark apartment floor, and a phone camera pointed at a circuit board. That setup raised a better question than it answered: why does lighting matter so much for precision work, and what do professionals actually use? This episode works through the real numbers — CRI and the R9 spec that gets left off every box, lux at the work plane, flicker thresholds you can't see, and the 45-degree two-source geometry that kills shadows. Then it turns to the newer problem: once you're photographing a board and asking an AI about it, lighting stops being an eye problem and becomes an image problem.
