Frequently Asked Questions
Can this 230V lamp be used in a standard 120V candelabra socket?
The bulb physically fits standard E12 miniature candelabra sockets, but operating a 230V incandescent filament on 120V power produces only a very dim, deep-orange filament glow. It requires a 230V supply to reach its rated 65-lumen brightness.
What ordering codes or manufacturer crosses match this bulb?
This lamp carries Sylvania NAED number 16717 and corresponds to ordering code 10S6230V (also referenced as 10S6/230V). It matches standard industry 10W 230V S6 candelabra indicator specifications.
When a legacy 230-volt control panel or imported instrument needs a true pilot light, an original Sylvania incandescent filament delivers the exact warm glow the designers planned for. Thread it into the socket and put the panel back in service.
