What to Prepare for a Custom LED Profile Inquiry.

1. Explain the application

Describe the lighting product or project and where the profile will be installed. Identify the mounting surface, surrounding finish, cable route and access needed for assembly or maintenance. A sketch, photo or reference section can help explain the requirement. Tell the supplier which aspects are still being developed. This gives the feasibility review useful context without assuming that a photograph represents an approved installation detail.

Compare custom manufacturing options, MOQ and production terms before preparing your specification.

2. Choose an existing section or discuss a new one

Decide whether an existing section is a suitable starting point. An unchanged cross-section can be discussed with different lengths, finishes, machining or packaging; whether any additional setup is needed depends on the order. If the required section is not available, provide a drawing or sample for a new cross-section review. A new profile may need extrusion tooling. Diffuser or accessory geometry can require separate review and tooling; the quotation should identify the proposed scope.

3. Provide your drawing and critical fit requirements

Share your own section drawing or sketch, intended lengths and reference images where available. Mark the dimensions that must fit adjacent parts and identify requirements that can be discussed. Include the LED strip and connector dimensions, mounting method, cable exits and finish build-up. If a dimension is unknown, identify it as an open question rather than guessing. NIUYUAN can review the material you provide; product section images may be shown as references, but downloadable product DWG or PDF drawings are not offered.

4. Specify the finish and matched components

Identify the desired finish and any color reference. Anodizing, powder coating and agreed color references can be discussed. List the intended diffuser, end caps and mounting clips, with quantities and any cable-entry requirements. Confirm the fitting interface against the selected section instead of assuming that covers fit every profile. PC or PMMA diffuser requirements can be discussed; silicone covers are available for certain profiles, with the applicable model and fit confirmed for the request. The quotation defines the components supplied.

5. State quantities, lengths and destination

Provide the estimated quantity per model and finish, required cut lengths, destination and requested timing. NIUYUAN standard supply lengths are 1 m, 2 m, 2.5 m and 3 m, and custom lengths are supported. MOQ is 1,000 pcs per model and per finish; custom sections have the same MOQ of 1,000 pcs. Tell the supplier about labeling, private-label packaging and any inspection requirements so they can be reviewed against the proposed order.

6. Review the quotation, sample and approval steps

Ask for the proposed profile, finish, components, quantities and any tooling to be identified separately in the quotation. LED strips, power supplies and controllers are not included unless stated in the quotation. Samples are free; the customer pays freight. Sample quantity is set per project, standard samples are usually ready within 7 days, and custom samples are arranged case by case, by agreement. Lead time is 20-30 days for all orders from receipt of prepayment. Tooling development takes about 7 days and is not included in the custom order production lead time. Agree on the drawing revision, sample and specification before production.
