Plug-In String Lights

-- Steady & Reliable Manufacturer --

Product Overview

Plug-in string lights connect to a wall socket through a power cord or an adapter and need no battery or solar panel. They are used where a mains socket is within reach, such as shop fronts, restaurant terraces, balconies, event halls and homes. Ningbo Hengboyi Lamp Co., Ltd. produces mains and low-voltage strings at its factory in Yuyao, Ningbo.

The website states that mains versions are rated AC220-240V and need no additional transformer. A US standard version is listed for AC120V 60Hz with an E26 base. The S14 detachable string is listed with a 16A EU cord, and the pixel-level controllable string uses a 12 V 0.5 A EU adapter. The S14 pendant 3.5 V string takes AC220-240V as input and gives DC 3.5 V 350 mA at the lamp.

Lead and extension lengths are published as 1.5 m lead with a 0.25 m or 0.5 m extension cable on the S14 and G45 models, and a 0.4 m extension cable on the G40 clip-on model. Up to 6 strings can be connected end to end on the models that publish the value, and the US string is limited to 1200 W in total.

Buyers are importers and distributors, e-commerce sellers, retail chains, hotel contractors and lighting brands. Plug type, instruction language and carton marking are agreed in the specification, since the plug is the part that changes with the destination country.

Technical Specifications

The table lists the supply data published for the plug-in models on the Hengboyi website. Supply voltage, lead length and extension length are shown for each, since these decide whether a string reaches the socket and how many strings share it.

The certification page displays three certificate images. The product pages state the protection rating and the supply voltage per model, and these values are the reference when a certificate copy or a test report is requested. The table shows what each listed certification covers.

Procurement FAQ

  • Q: What is the MOQ for Plug-In String Lights?
  • A: The minimum order quantity depends on the model and on the level of customization. Catalog models and models changed in plug type, supply voltage and cord length 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 Plug-In String Lights, the sample is checked for plug type, supply voltage and cord length before it is approved for mass production.
  • Q: Can Plug-In String Lights be made under our own brand?
  • A: Yes. OEM and ODM services cover product design, specifications, packaging and branding. For Plug-In 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.
