What to document first

For antique light bulbs, document the filament, glass shape, base type, maker marks, patent dates, packaging, voltage markings, and condition. Small differences can separate common bulbs from specialist collectibles.

Do not test old bulbs casually. Fragile glass, early filaments, and unknown electrical condition make display safety and preservation part of the appraisal conversation.
