Up for consideration is a vintage New Old Stock (NOS) Radiant 75W 30V T8 Smoke Detector Light Bulb. Manufactured by the Radiant Lamp Corporation, this highly specialized incandescent is a fantastic piece of obscure legacy fire and smoke detection tech. The bulb features a BA15d double contact bayonet base and a C13 filament configuration, engineered specifically for "burn base down" (EXDL) operation on a 30V DC circuit.

​As specialists in sourcing and preserving vintage industrial, medical, and scientific lighting, we ensure all inventory is properly cataloged and inspected. The bulb is unused and comes in its original factory packaging featuring classic mid-century typography. The box shows minor shelf wear consistent with age, making it a great display piece for collectors of early industrial safety equipment or rare specialty bulbs.
