@dandydee,
The bulbs you refer to are probably made in China. (Smaller size Glass Flame)
Do not measure the glass bulb. It is the metal base that is important.
"C" stands for Candelabra. "E" stands for Edison. The "26" is Millimeters.
C26 and E26 are the same base light bulb socket. (1.03 inches)
This is the standard size light bulb socket in North America.
You are looking for the large size candelabra "C26" light bulb.
You can purchase this bulb at any electrical lighting store. {25w, 40w, 60w}
Make sure you purchase 110 Volt, 25 Watts, C26 (Flame Shape) = [Candelabra]
If you do not know the answer. It is not a silly question.
You can buy these bulbs at. Canadian Tire, Home Hardware, Lowe's, Home Depot, Walmart, Ace Hardware, Any Hardware store. Ebay and Amazon.
Now you know. Hope you understand.
