Spiral String Lights

-- Steady & Reliable Manufacturer --

Product Overview

Spiral string lights use screw-type lamp sockets, and the word spiral appears in several Hengboyi model names on E12 and E27 bases. The screw socket holds the bulb in the string, and on models built with replaceable lamps it lets the lamp be changed. Ningbo Hengboyi Lamp Co., Ltd. produces these strings at its factory in Yuyao, Ningbo.

Published spiral models include the G40 clip-on E12 spiral colored and warm white strings, the G45 pendant E27 spiral colored string, the S14 pendant E27 spiral warm white string with a 3.5 V low voltage version, the S14 hanging E27 spiral RGBWY string, and the E27 spiral RGB infrared remote control string.

The G40 colored model carries 10 bulbs at 1 W on a 5 m string, rated IP42. The infrared model carries 10 bulbs at 3 W with 0.5 m spacing, PVC 2 × 0.824 mm² wire and IP44. Bulb shapes in the family are G40, G45 and S14 on E12 and E27 bases.

Buyers are importers, distributors, e-commerce sellers and lighting brands. Base, color, voltage, wire and packaging can be customized, and both integrated and replaceable lamp versions are produced on the website.

Procurement FAQ

  • Q: What is the MOQ for Spiral String Lights?
  • A: The minimum order quantity depends on the model and on the level of customization. Catalog models and models changed in screw socket, base size and bulb shape 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 Spiral String Lights, the sample is checked for screw socket, base size and bulb shape before it is approved for mass production.
  • Q: Can Spiral String Lights be made under our own brand?
  • A: Yes. OEM and ODM services cover product design, specifications, packaging and branding. For Spiral 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.
