Figure 1 shows a socket with cardboard insulator. Please note that not all sockets require a cardboard insulator.
Determining the correct socket type and candle cover height:
To determine the correct candle cover size you must carefully measure for the correct diameter as shown in Fig.2. This is an important step since our candle covers are manufactured using lighting industry standard sizing.
There are two common socket sizes on U.S. lighting. Most lamp sockets are either an Edison (also known as ‘medium base’ or ‘standard’) size or a candelabra size. There are, however, some uncommon sizes including “intermediate” or European sizes for which candle covers and replacement cardboard insulators are very difficult to locate. It is possible for us to manufacture European sizes by custom order in beeswax only, but not in resin. Please contact us if you determine that you have a European size.
Here is how to determine the socket size and candle cover height:
A candelabra socket has an outside diameter of 3/4” (shown in Fig. 2) and will require a candelabra candle cover. This candle cover has an inside diameter of 13/16” to allow it to fit comfortably over the socket.
A medium base socket (or Edison) has an outside diameter of approximately 1-1/8” and will require a medium base candle cover which has an inside measurement of 1-3/16” (See Fig. 3).
A European socket has an outside diameter of just under 1" and will require a European candle cover with an interior of 1". Please contact us if you determine that you have a European size.
To determine the height, measure from the point where the bottom of the candle cover will sit up to the top of the socket.
When determining the height, the candle cover should fit level with the top of the socket or insulator, but never above. To determine the correct height, simply measure from the location where the bottom of candle cover will sit to the top of the socket. Incorrectly installed beeswax candle covers (too tall) will melt. Resin covers that are too tall may scorch and discolor. Please measure carefully and do not rely on an existing candle cover height until you have determined that it was installed correctly.
Figure 3 shows the measurement of a medium base (Edison) candle cover.
Please carefully read the following for directions on installing a candle cover:
Beeswax candle covers are limited to a maximum bulb wattage of 25W.
Resin and cardboard candle covers can safely handle bulb wattage of 60W when installed correctly.
Always include the U.L. listed cardboard insulator that covers the socket terminals (screws where the wire is attached) (see Fig. 1). Failure to include the insulator may create an electrical hazard. If the cardboard insulator is worn or brittle from age, it should be replaced. Some modern sockets do not have the terminals exposed and in this case will not have a cardboard insulator. If the wiring or socket appears damaged in any way you will probably want to replace the socket and all of the wiring connected to the socket. You may need to contact a professional lamp restorer who can give you advice and/or an estimate for re-wiring the lamp or fixture.
When determining the height, the candle cover should fit level with the top of the socket or insulator, but never above. Incorrectly installed beeswax candle covers (too tall) will melt. Resin candle covers that are too tall may scorch.
