154 of the 293 Rynix fixtures that publish a bulb base state E12, 99 state the E26 medium socket and 30 state a G9 pin socket. Five state GU10 and seven state another base, and two listings state two bases at once. The remaining 268 of our 561 live fixtures do not state a socket, so the base has to be confirmed with us before you buy bulbs.
How do you tell an E12 socket from an E26 by looking at it?
The number in an E-base is the diameter of the threaded metal screw base in millimetres. E12 measures 12 mm across and is usually called a candelabra base. E26 measures 26 mm and is usually called a medium base, the same size as a standard household lamp bulb in the United States. Put a ruler across the socket opening in the fixture and you have your answer in one measurement.
G9 is not a screw base at all. It is a two-pin capsule: the bulb ends in two small loops of wire that push straight into the socket, with no threading and no twisting. A G9 bulb cannot be forced into an E12 socket and an E12 bulb cannot be forced into a G9 socket, so this is the one distinction that is impossible to get wrong once you have seen both.
On our listings the base appears in one of two places. Some fixtures carry a structured bulb cap field, and 232 live fixtures do. Others print it inside the description, on a Light Source line, a Socket or Socket Type line, a Bulb Base line or a Bulbs Included line. We parsed 61 more that way, which is how the total reaches 293.
Which fixture types use which base?
Coverage is uneven across the catalogue. Wall sconces state a base on about half their listings, chandeliers and ceiling lights on around six in ten, pendants on a third.
| Fixture type | Live listings | State a bulb base |
|---|---|---|
| Wall sconces | 205 | 104 |
| Chandeliers | 172 | 110 |
| Pendants | 117 | 40 |
| Ceiling lights | 65 | 39 |
| Lanterns | 2 | 0 |
E12 follows the multi-arm pieces where a slim candle-style lamp suits the arm: 66 of the 154 are chandeliers and 55 are wall sconces, against 7 pendants. E26 spreads across the catalogue instead, with 34 of the 99 on chandeliers, 27 on wall sconces, 26 on pendants and 12 on ceiling lights. G9 sits mostly on wall sconces, 16 of the 30, with 7 chandeliers, 5 pendants and 2 ceiling lights.
Where on the listing is the base written, and what do the odd ones say?
The structured field is the tidier of the two sources, but it only covers 232 of the 293. The rest is description text, and the wording is not standardised. Light Source is the most common label, on 25 of those 61; a Socket or Socket Type line accounts for 19; a Bulbs Included, Bulb Included or Bulb Base line supplies the last 17.
These live listings show the spread, including every base outside the four main ones.
| Fixture | Price | Where the base is written |
|---|---|---|
| Coronet Gold Lantern | $868.00 | Description: Socket Type: E12 |
| Heirloom Sconce | $436.80 | Description: Socket Type: E26 |
| Black Cone Shade Wall Sconce | $522.37 | Description: Socket: E12 |
| Ashleigh Glass Wall Sconce | $292.60 | Description: Light source: 2 x G9 bulbs |
| Shelton Flush Mount | $576.00 | Structured field: E12 and E26 |
| Magnus Wall Sconce | $286.40 | Structured field: E10 and E12 |
| Tremont Picture Light Sconce | $280.00 | Structured field: E17 |
| Velma Pendant | $516.00 | Description: Bulbs Included: 1 / E27 / 6W Maximum |
Prices are the lowest listed variant price on 2026-09-17, given to identify the listing rather than as a quote. Seven listings state a base outside E12, E26, G9 and GU10: three carry a structured value of Other, two state E10, one states E17 and one states E27. Those are worth a message to customer service before you order bulbs.
What should you do when the listing does not state a base?
268 of the 561 live fixtures carry no socket information in either the structured field or the description. We are not going to guess at those from a photograph, because a candle sleeve of the same shape can sit over an E12 or an E26 socket and the picture does not settle it.
Ask customer service for the socket type and the bulb count before you order bulbs, and order the fixture and the bulbs separately if the bulbs are not in the box. One field that looks like a shortcut is not one: 246 live fixtures carry a bulb-type field and every one of them reads LED, but only 52 of those also state a base and 21 of them describe an integrated LED with no socket at all, so that field does not tell you what to order.
What else do people ask about bulb bases?
Can an E12 bulb be used in an E26 socket?
Not without an adapter; E12 is a 12 mm candelabra base and E26 a 26 mm medium base. 154 Rynix fixtures state E12 and 99 state E26, so check the listing's Light Source or Socket line before buying bulbs.
Are G9 bulbs harder to find?
G9 is a two-pin capsule base used on 30 Rynix fixtures, 16 of them wall sconces. LED G9 capsules are stocked by most bulb retailers, so the base itself is not the hard part of the order.
Why do so many fixtures not state a base?
268 of the 561 live fixtures do not publish one. If a listing you want is among them, ask customer service for the socket type before ordering bulbs; we do not guess it in this guide.
Can one listing state two different bases?
Two do: Shelton Flush Mount states E12 and E26, and Magnus Wall Sconce states E10 and E12. Each is counted once in the 293 and once in each base's own count.
How we measured this
On 2026-09-17 we pulled every active product from the rynixlighting.com admin catalogue and kept the 561 lighting fixtures that are published to the online store, setting aside 66 furniture listings and 97 active products that are not published and return a 404. For each fixture we read the structured bulb cap field, present on 232 of them. For the other 329 we searched the description for a Light Source, Socket, Socket Type, Bulb Base or Bulbs Included label followed within 40 characters by E10, E12, E17, E26, E27, G9 or GU10, which added 61 more, for 293 in total. Two listings state two bases and are counted once in the 293 and once under each base, which is why 154 plus 99 plus 30 plus 5 plus 7 comes to 295. Fixture-type counts merge the singular and plural product types the catalogue uses and include the 2 lanterns, so the five rows add to 561. Prices are the lowest listed variant price on the same date. Where a value is absent we have said so rather than filled the gap.
