LONGER B1 20W Basic Set
Published 20W label; optical basis unresolved
Original source-dimension diagram, not a product photograph. Work area is not machine footprint. Common scale across reference cards.
A project-sized comparison
Choose up to four exact configurations. Facts retain their source and scope; no overall performance winner is invented.
Only selected configuration packets are loaded. Opening a shared link never changes a saved selection. Missing evidence is unknown, not a zero or a negative test result.
