I recently bought 10 of these mint in an orignal box that held 30. Maybe I should be in the bulb section. There is no wattage listed but I have some Noma 3 watt and they are about half as bright. They are gorgeous when lit with a double lope filament much like the old carbon filaments. There are no patent #'s. They're candelabra base. Can anyone tell me about them or the company? Box address says, St. Louis 6, Missouri.
