A collection of three large vintage industrial light bulbs dating from the 1950's and 60's. Each light bulb is of a different make/model, with this collection including: (1) Westinghouse 300Watt, (1) Lustra 500Watt, and (1) Sylvania 500Watt. Lightbulbs measure approximately 9" in length and have not been tested, but are in very good cosmetic condition and are perfect for decorative display.
