Vintage 4ft T12 Blacklight Bulbs 40W (Sylvania & GE) NOS Pair

Selling a pair of rare, vintage 4-foot T12 fluorescent Blacklight Blue (BLB) tubes. These feature the deep purple filter glass perfect for theater effects, mineral/gem identification, document verification, or Halloween displays. Includes two premium, vintage American-made bulbs: • 1x Sylvania Lifeline F40-BLB (40 Watt) • 1x General Electric (GE) F40/BLB (40 Watt) Condition: Likely unused New Old Stock (NOS). The bi-pin metal contacts are extremely clean with no burn-in rings on the glass ends. They have been stored in their original corrugated factory cardboard sleeves, which show vintage wear from storage. Both bulbs have identical specifications and will run perfectly together in any standard dual-bulb 4ft shop light fixture or ballast. Sold as-is due to vintage nature.
