OEM vs ODM vs full custom: which model fits your project
Most sourcing conversations skip this step and go straight to price. That is a mistake, because the three models differ in ways that surface late — usually when a second order arrives and the tooling turns out not to be yours, or when a "custom" fixture turns out to be a catalogue body with your label on it.
| Model | Who owns design & tooling | What you get | What drives MOQ | Typical lead time | Best for |
|---|---|---|---|---|---|
| OEM | Design is yours; tooling stays with the factory unless you fund it | Your specification built to your drawing, under your brand | Extrusion die, LED/driver minimum packs | 4–6 weeks | Brands with in-house product design |
| ODM | Factory owns design; you own the brand and label | Existing platform, re-branded and re-configured | Catalogue MOQ per model | 2–4 weeks | Distributors, private label, fast line extensions |
| Full custom | New profile, optic or driver; tooling negotiable | Purpose-built luminaire for one project | New die + component minimums | 8 weeks and up | Airports, museums, flagship hospitality |
The practical rule: if the fixture must match an existing architectural detail — a reveal, a slot, a curve in the ceiling — you are in full custom territory, and the timeline should be planned around tooling, not around assembly.
The custom luminaire development process, step by step
- RFQ and technical brief. Drawings, mounting condition, output target, CCT, CRI, beam, dimming protocol, finish, IP rating, destination market. Vague briefs are the single largest source of rework.
- Feasibility and photometric concept. The factory checks whether the target lumen output fits the profile's heat dissipation, and runs an illuminance check (DIALux or equivalent) for the actual room geometry.
- Quotation and MOQ confirmation. Price, MOQ and lead time should be quoted together, per configuration — a quote without an MOQ attached is not a quote.
- Prototype or sample build. Usually 1–3 units for approval; this is where finish, joint detail and glare control get tested in the hand, not on paper.
- Photometric and safety testing. LM-79 photometric report and an IES/LDT file per model; LM-80 data for the LED package if warranty terms depend on it.
- Sample approval and golden sample. Signed sample retained by both sides. This is the reference for any later dispute about colour, finish or output.
- Production, QC and pre-shipment inspection. Aging test before packing, then a documented inspection against the approved sample.
What actually drives your MOQ
MOQ is not a sales policy — it is a manufacturing floor. Five variables set it, and only some of them move:
| Driver | Why it sets a floor | Negotiable? |
|---|---|---|
| Extrusion die and run length | A die has a minimum economical run; short runs carry the same set-up cost as long ones | Partly — share a die across models, or accept a longer profile that is cut down |
| LED and CCT binning | Each CCT/CRI combination is binned separately; rare bins have reel minimums | Yes — narrowing to two or three CCTs lowers the floor |
| Driver minimum order | Dimmable drivers (DALI, 0–10V, Zigbee) are bought in packs | Yes — switching to a widely stocked driver shortens lead time too |
| Surface finish batch | Powder coating has a minimum batch weight per colour | Partly — standard RAL colours share batches; specials do not |
| Packaging and labelling | Custom cartons and labels are printed in runs | Yes — plain cartons for first orders |
Ask for MOQ in writing, per configuration, before the design is frozen. A supplier who quotes MOQ after sampling has already spent your tooling budget.
Lead times: what 20–25 days actually covers
For a custom linear or recessed luminaire built on existing tooling, a 20–25 day production window breaks down roughly as follows. The numbers are indicative — they shift with driver availability and finish complexity — but the structure holds, and it is the part buyers usually cannot see.
| Stage | Duration | Can it run in parallel? |
|---|---|---|
| Drawing and engineering review | 2–3 days | No — everything downstream depends on it |
| Sample or prototype | 5–7 days | Partly — component purchase starts during this stage |
| Component procurement (LED, driver) | 3–5 days | Yes — overlaps sampling |
| Extrusion, machining, finishing | 7–10 days | Yes — finishing overlaps machining across batches |
| Assembly and aging test | 3–4 days | No |
| QC and packing | 2 days | No |
Two things sit outside that window and should be planned separately: new tooling (a new extrusion die adds 15–25 days, once) and freight. Projects that go wrong usually went wrong before day one — the RFQ was incomplete, the sample was approved by email without a retained golden unit, or the finish changed in week two.
Delivered reference: NAIA Terminal 3, Manila
VOC Lighting supplied the luminaires for Terminal 3 at Ninoy Aquino International Airport (NAIA), Manila — including the vaulted-ceiling cove and linear lighting, recessed downlights, and the backlit feature walls in the terminal's lounge and dining areas. Production ran on a 20–25 day window.
| Project | Ninoy Aquino International Airport (NAIA), Terminal 3 |
| Location | Manila, Philippines |
| Scope | Luminaire supply — vaulted ceiling cove and linear lighting, recessed downlights, backlit feature walls, meeting-room perimeter cove |
| Production lead time | 20–25 days |
| Applications | Departure lounge seating, dining and buffet area, bar counter, wine display wall, meeting room |
Why an airport terminal is a demanding brief
The geometry is the hard part. Vaulted and arched ceilings need linear runs that follow a curve without visible breaks, and the cove has to read as one continuous line of light from every seat in the room — any binning difference between modules shows up immediately on a surface that large. Three requirements dominate this kind of project:
- Continuity over long runs. Consistent flux and colour across hundreds of joined modules, which means tight binning and a single production batch per ceiling zone.
- Glare control in seating areas. Recessed downlights positioned so that nobody looking up from a lounge chair sees the source directly — usually a deep baffle or a shielded optic.
- Maintenance access. Terminal ceilings are serviced while the building stays open; fixtures have to be reachable and replaceable without disturbing adjacent modules.
The same discipline applies to smaller projects: tunable white specification and CRI and R9 values are decided at the RFQ stage, not at handover. For outdoor and landscape work the constraints shift again — see the outdoor and landscape specification guide.
Documents to demand at each stage
| Stage | Document | Why it matters |
|---|---|---|
| RFQ response | Specification sheet, dimensions, finish code | Locks the brief before tooling decisions |
| Sampling | LM-79 photometric report, IES/LDT file | Lets you verify output in your own lighting design software |
| Certification | CE Declaration of Conformity, UL/ETL file number, RoHS report | Destination-market compliance; must match the model supplied |
| Production start | Golden sample signed off by both sides | The reference for colour, finish and joint quality |
| Pre-shipment | QC report, aging test record, packing list | Evidence the batch matches the approved sample |
Five things that delay a custom order — and how to prevent them
- An incomplete brief. Missing dimming protocol or IP rating forces a redesign after quotation. Use the 12-item checklist below.
- Sample approved informally. "Looks good" in a chat is not approval. Sign a golden sample and keep one unit.
- Late CCT or finish change. Changing CCT after LED reels are cut wastes the reel and restarts binning. Freeze CCT and finish at sample approval.
- Certification discovered late. If the destination market needs a specific certificate, raise it in the RFQ — retrofit certification mid-production is the longest delay of all.
- Shipping documents. HS code, incoterm and consignee details wrong at booking adds days at the port, not at the factory.

FAQ
What is the difference between OEM and ODM in lighting?
In OEM, the design is yours: you provide the drawing or specification, and the factory manufactures to it under your brand — but the tooling usually stays with the factory unless you pay for it. In ODM, the factory owns the design and you apply your brand, label and configuration to an existing platform. OEM generally means higher engineering effort and a higher MOQ driven by the extrusion die; ODM is faster and cheaper to start, but the product is not exclusive to you. Ask explicitly who owns the tooling and whether the same body is sold to competitors before you commit.
What is a typical MOQ for custom architectural lighting?
MOQ is set by manufacturing floors, not by sales policy. The five drivers are extrusion die run length, LED and CCT binning, dimmable driver minimum packs, minimum powder-coating batch per colour, and packaging runs. On catalogue-derived ODM models, MOQ is typically the catalogue minimum per model. On a fully custom profile it is set by the new die plus component minimums. Always request MOQ in writing per configuration at quotation stage — a supplier who quotes MOQ after sampling has already spent tooling budget.
How long does custom architectural lighting take to produce?
For a defined luminaire built on existing tooling, a 20–25 day production window is realistic — engineering review 2–3 days, sampling and component procurement in parallel, extrusion and finishing 7–10 days, assembly with aging test 3–4 days, then QC and packing 2 days. Two items sit outside that window: new tooling, which adds 15–25 days once for a new extrusion die, and freight. Industry-wide, fully custom builds often run 6–10 weeks, largely because tooling and approval loops are planned sequentially.
Can CCT and CRI be customized for a project?
Yes — CCT and CRI are the most commonly customized parameters, because they are determined by the LED package and binning rather than by the body. Typical project options are fixed single-colour CCT such as 1800K or 2700K for hospitality and heritage interiors, and tunable white ranges such as 2700–6500K for spaces that change use through the day. CRI is specified alongside, with R9 confirmed if the space has warm materials or merchandise. The constraint to plan for is binning: each CCT/CRI combination is a separate bin with its own minimum reel quantity, which is why narrowing the CCT list lowers MOQ and lead time.
Do I own the tooling and the drawings in an OEM project?
Not automatically. In most OEM arrangements the factory retains the extrusion die unless the buyer funds it, and die ownership is stated — or not — in the quotation. If the design is strategic, negotiate die ownership in writing, or at minimum secure an exclusivity clause covering the profile and the project. Drawings are a separate question: the buyer usually owns the design intent, but the factory owns manufacturing drawings derived from it. Clarify both before the first production run, not after.
What documents should I receive with a custom lighting order?
At minimum: a specification sheet confirming dimensions and finish, an LM-79 photometric report with an IES or LDT file per model, certification documents that match the model actually supplied (CE Declaration of Conformity, UL or ETL file number, RoHS report), a signed golden sample retained by both sides, and a pre-shipment QC report with the aging test record. The IES file matters most for design verification — without it you cannot confirm the delivered output in your own lighting calculations.
What causes delays in custom lighting production?
The five recurring causes are an incomplete RFQ (missing dimming protocol or IP rating), informal sample approval without a retained golden unit, CCT or finish changes made after production starts, certification requirements raised late rather than at RFQ stage, and shipping document errors at booking. None of them are manufacturing failures — they are specification and approval failures, which is why they are avoidable. Freeze CCT and finish at sample approval, and confirm the destination-market certificate list before the order is placed.
How do I brief a lighting factory for a custom project?
Send a single RFQ covering twelve items: project location and destination market, application and mounting, profile dimensions or the architectural detail to match, wattage and delivered lumens, CCT and CRI including R9, beam or optic, dimming protocol, finish and RAL code, IP rating, required certification, quantity per SKU with annual forecast, and required delivery date with incoterm and port. A brief covering all twelve turns into a quote with an MOQ and a date attached; a brief missing three of them turns into a design conversation that restarts the clock.
Summary
Custom architectural lighting is decided by the commercial model before it is decided by price. OEM, ODM and full custom differ in tooling ownership, MOQ floor and lead time — and the lead time only holds if the brief is complete and the sample is signed. For a defined luminaire on existing tooling, 20–25 days of production is achievable; new tooling adds 15–25 days once. The reference project on this page, NAIA Terminal 3 in Manila, was delivered on that window, across vaulted ceiling coves, recessed downlights and backlit feature walls. If you are briefing a factory this quarter, start from the 12-item RFQ checklist above.
