Hi,
I have a "STAR" bulb,manufactured in Niles Ohio. Last patent date on paper label inside stem is 28 Mar '03. Paper label on bulb is intact as is filament. No carbon shadow,so I imagine little or no use. Bulb has E.S. base with black glass insulation. Bulb is about size of ordinary modern household bulb,rated at 220 Volts and 24 Candlepower.
Has anyone got info on this item?
Regards,
Ron.
