Brent Hull traces the evolution of residential lighting from 19th-century gas lamps to early electrical systems and the lasting impact those transitions have on how houses are built today. The episode explores the rivalry between AC and DC power, changes in wiring methods, and why understanding this history matters when designing or restoring a home with architectural integrity. A visit to an architectural salvage yard reveals how historic lighting fixtures differ from modern counterparts—and how reclaimed pieces can be thoughtfully integrated into new construction. Through history, craft, and context, the episode shows how lighting choices can either weaken or strengthen a home’s architectural story.
