E12 Socket String Lights

-- Steady & Reliable Manufacturer --

Product Overview

E12 is the small screw base, also called the candelabra base, and strings with E12 sockets take small bulbs in G40, C7 and ST38 shapes. The base suits low-power lamps, and the Hengboyi website lists E12 models at 0.5 W and 1 W per lamp. Ningbo Hengboyi Lamp Co., Ltd. produces these strings at its factory in Yuyao, Ningbo, and has exported decorative and solar lighting since 2012.

The G40 clip-on E12 spiral colored string carries 10 bulbs at 1 W each, about 50 lm per lamp, on a 5 m string with a 0.4 m extension cable and a 1.5 m lead, rated IP42. The C7 strawberry pendant string and the C7 smooth-surface integrated string are colored models at 0.5 W per lamp. The ST38 vintage E12 string is listed at 1 W warm white in pendant and integrated versions.

The G40 integrated solar string also uses an E12 base. It is listed with 10 lights on a 5 m string, IP44, and activates at dusk, so the E12 family covers mains, adapter and solar supply. A warm white G40 clip-on version at 2700K is listed next to the colored one.

Integrated and replaceable lamp versions are both produced. Buyers are importers, distributors, e-commerce sellers and lighting brands, and the website states that voltage, length, wire type, appearance and packaging can be customized under the OEM and ODM service.

Technical Specifications

The table lists the E12 strings published on the Hengboyi website, with the data from each product page. Lamp power, string length and ingress protection are the three values that separate the E12 models, and they are shown in the details column where the website states them.

Applications and Target Customers

The table sets out who buys E12 strings and which published models match each use. The use cases named on the G40 clip-on page include holiday decoration, commercial spaces, restaurants, balconies, courtyards and parties.

Customer TypeTypical Use and Relevant Series
Table 2. Summary of applications and target customers for e12 socket string lights.
Importers and distributorsImporters and distributors can organise an E12 stocking program around three bulb shapes, G40, C7 and ST38, all published at 0.5 W or 1 W per lamp, so one socket size covers several retail price points.
E-commerce sellersE-commerce sellers can list the G40 clip-on E12 set as a pack of 10 bulbs on a 5 m string with a 0.4 m extension cable, and the page states that up to 6 strings can be connected.
Retail chainsRetail chains can run colored and warm white sets from the same base, using the G40 clip-on colored model and the 2700K warm white version in matching packaging.
Hotels and engineering projectsHotels and engineering projects can use the E12 strings for covered terraces and courtyards, and the G40 integrated solar string at IP44 where no mains socket is close to the fixing points.
Lighting brandsLighting brands can ask for a brand-specific bulb color, string length or packaging on the E12 base, since appearance and packaging fall within the OEM and ODM scope stated on the website.
Solar installationsThe G40 integrated solar string uses an E12 base, has 10 lights on 5 m, is rated IP44 and starts at dusk, which suits fences and pergolas without a socket

The E12 base carries lower lamp power than E27, so strings on this base are chosen for small bulbs and for locations where the lamp power published at 0.5 W to 1 W is sufficient.

Procurement FAQ

  • Q: What is the MOQ for E12 Socket String Lights?
  • A: The minimum order quantity depends on the model and on the level of customization. Catalog models and models changed in base size, bulb shape and lamp power can carry different quantity levels. Send the model name, bulb shape, base type, voltage and target quantity to sale2@hengboyi.com, and the sales team replies with the MOQ for that item.
  • Q: How are samples charged and how long do they take?
  • A: Sample production is the second stage of the OEM/ODM process on the website. Sample cost and sample time are quoted per model, since a catalog item and a newly developed item need different work. The quotation states both before the sample is started. For E12 Socket String Lights, the sample is checked for base size, bulb shape and lamp power before it is approved for mass production.
  • Q: Can E12 Socket String Lights be made under our own brand?
  • A: Yes. OEM and ODM services cover product design, specifications, packaging and branding. For E12 Socket String Lights, the brand is normally applied to the packaging, the instruction sheet and the product label. Brand name, logo, packaging design, string length, voltage and wire type can be set to the buyer's requirements and are recorded in the project specification.
  • Q: What payment terms are used?
  • A: Payment terms are stated in the quotation and the sales contract for each order. Buyers can state the preferred terms at the inquiry stage so that they are agreed before production is scheduled.
  • Q: What warranty applies?
  • A: The website lists delivery and after-sales support as the fourth stage of the OEM/ODM process. The warranty period and the handling of defective units are written into the sales contract, and the buyer can request this wording during quotation.
