Custom Lighting Project Documentation & Buyer Support

Send the intended bulb shape and size, glass and filament direction, base, voltage and frequency, target market, fixture or control information, estimated quantity, packaging needs and project timing. Reference photos are useful, but dimensions and electrical requirements should be stated separately.

No. A universal library can be misleading because custom shape, components, voltage or market requirements may change what applies. We review available documents against the exact product and configuration before order confirmation.

Document availability depends on the exact bulb, electrical version, components and destination market. Please list the required standard at the inquiry stage. We will confirm whether existing documentation is applicable or whether a different product direction or separate testing is needed.

At minimum it should identify the bulb family, dimensions, glass finish, filament or internal design, base, rated voltage and frequency, power, color appearance where relevant, dimming requirement, label version, packaging reference and approved revision.

Changes should be listed against an identifiable sample or revision. The updated appearance, electrical details and packaging implications are reviewed, then the final accepted version becomes the bulk-production reference. A change after approval may affect cost, timing or testing.

Yes, when both sides clearly identify the approved sample and the accompanying specification. Because some details are not visible in a photo, the sample reference should be used together with confirmed electrical, label and packaging information.

Depending on the order, this may include product labels, rating information, logo placement, barcodes, unit boxes, protective inserts, carton quantities and carton marks. Artwork and printed information should be approved before printing.

Agreed inspection photos or a summary can be coordinated for the order. The inspection scope—such as appearance, lighting function, labeling, quantity or packaging—should be agreed in advance. Buyers may also arrange third-party inspection when this is confirmed before shipment.

Usually they can be reviewed. Send purchasing, quality, specification or approval templates early so we can confirm which fields are relevant and who is responsible for each item. Late document requirements can delay sample or production approval.

Limit shared information to what is needed for feasibility and development, and identify confidential files clearly. NDA terms can be reviewed when required. Confidentiality, ownership, exclusivity and permitted use are governed by the written agreement accepted by both parties.

No. An NDA normally addresses confidential information; exclusivity, territory, ownership, tooling and sales restrictions are separate commercial terms. Any such protection must be clearly defined and agreed in writing.

Use a stable SKU or project reference together with the approved specification, sample or revision, label artwork and packaging version. When requesting a repeat order, also state whether any component, regulation, branding or destination-market requirement has changed.

Provide the order and product reference, affected quantity, clear photos or video, label information, packaging condition and the fixture, supply or dimmer used. Keep representative products and packaging until the cause and next action are reviewed.

As early as possible—ideally during the first feasibility review. Requirements introduced after sampling or production begins may require a different product, additional testing, revised artwork, extra cost or a longer schedule.
