Scope of service

Six kinds of support, from selection to delivery

From sample validation to volume delivery, every step has an owner and a document — nothing is deferred to "after-sales".

Sample testing

Samples and testing support to verify dimming compatibility, temperature rise and load behaviour.

3-year warranty

A 3-year warranty on standard products, under the promise of full rated power, flicker-free output and durable, safe operation.

7×24 technical response

Selection, wiring and commissioning questions are answered by phone and WeChat.

OEM / ODM

Soldering, SMT assembly, drawing design, production debugging and electrical assembly; build-to-print, build-to-sample, private label and custom orders.

Full-process quality control

Control at every stage: incoming material, R&D design, production, testing, burn-in, packaging and outbound dispatch.

Selection and wiring specification

A professional selection and wiring specification with selection guidance, wiring diagrams and FAQs.

FAQ

Service questions

Warranty, customisation and protocol compatibility are the three things asked most often before an enquiry.

How long is the warranty?

Standard products carry a 3-year warranty; specific terms are defined in the purchase contract.

Do you support OEM / ODM?

Yes. Capabilities include soldering, SMT assembly, drawing design, production debugging and electrical assembly, supporting build-to-print, build-to-sample, private label and custom orders. Contact us for minimum order quantities.

How can I confirm dimming compatibility quickly?

Send the existing dimmer or host model, the wiring method and the fixture parameters; an engineer will match the five-in-one, 0-10V or DALI series.
