Case 40 — Lume comparison: keep exposure and charging conditions consistent · source wording exercise

Correction note for “Lume comparison: keep exposure and charging conditions consistent”: retain the wording beginning “Repeat with equal light source, charging duration, elapsed time and camera…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Retain the source wording beside any paraphrase.
