10- Late 60s/Early 70s Westinghouse Extended Service Light Bulbs 100 Watt

Vintage Made in USA Westinghouse extended service light bulbs in original packaging. 2500 Hr. Life - Runs at 90 watts on regular 120 volt grid so a little dimmer than regular 100 Watt. Noisy when dimmed but quiet and good condition otherwise. Dirty but cleaning removes imprint on bulb. Easily cleaned though which I can do if you’d like. You’ll still see the stamp These are rare and vintage bulbs. They weren’t made to this level of quality ever again.
