1. A Quantity Rule Doesn’t Travel Between Products

Buyers who have sourced one LED product often arrive at the next one with a number in mind. It is a reasonable instinct and a costly one: the quantity that made a mask viable came from that mask’s tooling, its enclosure, its packaging and its assembly sequence, and none of those transfer intact to a cap or a belt.

There is a partial exception worth knowing about. Products in the same family frequently share emitters, drivers and even firmware, which can reduce duplicated engineering and sometimes reduce a component-driven minimum. It only holds when the configurations are genuinely compatible and the supplier can control variants and traceability — otherwise the shared part becomes the thing that makes two products impossible to tell apart on the line.

For the underlying mechanics — why a minimum exists at all and what moves it — see our main MOQ explainer. This page is the comparison: four product forms, five customisation layers, one way to ask.

2. Compare Form Factors by Production Driver

Compare the forms by what constrains them, not by what they look like. The second and third columns below are general tendencies; the fourth column is the point, because in every case the tendency has to be confirmed rather than assumed.

Form	Often Shared With Other Forms	Where the Limit Most Often Sits	What to Verify
Mask	Emitters, driver, firmware — the electrical architecture.	The enclosure tool, plus assembly and test of a wearable that must fit.	Whether the minimum follows the housing (size variants multiply it) or the electronics.
Panel	The same electrical architecture, often with a larger emitter count.	Enclosure and packaging bulk — a panel’s carton can drive the economics before the device does.	Freight and packaging minimums, which can exceed the assembly minimum.
Cap (hair)	Driver and emitters, usually at a different density.	The housing tool and the fit of a worn shell; emitter layout is form-specific.	Whether the intended use changes the test scope, which changes the approval burden.
Belt or wrap	Emitters and driver; the substrate is where it diverges.	The flexible substrate or strap assembly, and its handling in production.	Whether a flexible part has its own purchase minimum independent of the finished unit.

None of those tendencies is a quotation. The purpose of the table is to tell you which question to ask first for each form, so that the answer you receive is about your product rather than about the category.

3. Separate the Customisation Layers

Ask for five separate quotes rather than one. Each layer can trigger a different minimum, a different one-time charge, a different testing requirement and a different approval gate — and when they are quoted together, the answer you receive is the highest of five numbers wearing one label.

• The standard model as listed. The baseline against which every other layer should be measured.
• Logo or label customisation. Often driven by a marking step rather than by the device, which is why it can change a minimum on an otherwise available product.
• Retail packaging customisation. Frequently carries a separate minimum from a packaging supplier — a different company from your device supplier.
• Cosmetic or material changes. Colour, finish, skin-contact material. May require material evidence even when performance is unaffected.
• Functional or structural changes. New tooling, new validation, a revised instruction and a revised technical file. The most expensive layer by a wide margin.

One caution on the classification itself: this five-layer structure is a way of organising the question, not an industry standard. Suppliers divide customisation differently, and some will combine two layers that you have separated. Confirm the categories with the supplier before you build a comparison on them.

4. Ask for a Comparable MOQ Matrix

Nine fields make one supplier’s answer comparable with another’s. Ask for them as columns, and treat a missing field as an open question rather than a detail to sort out later.

Field	What It Must State
Model and revision	The exact build the minimum applies to, not the product family.
Quantity basis	Per model, per colour, per configuration, per packaging version, or per total order — and whether variants combine.
Included accessories	What ships in the box, because an accessory can carry its own minimum.
Packaging	Whether artwork and any variant minimum are inside the figure.
One-time charges	Tooling, engineering, artwork and samples, itemised separately from unit price.
Test and documentation scope	Which reports are included and which are additional.
Lead-time assumptions	What the date depends on: materials, tooling, a production slot, your own approvals.
Quote validity	How long the figures hold, since component pricing moves.
Exceptions and their basis	Any departure from the stated minimum, with the evidence or condition behind it and whether it is a policy or a one-off.

This is the same discipline as a good RFQ, applied to one field. If you are building the fuller version, our RFQ structure covers the ten sections a mask brief needs.

5. Decide Around Risk, Not Around the Lowest Number

A smaller initial order reduces stock exposure and raises the unit cost, and may limit which customisation layers are available at all. A larger order improves pricing and increases the working capital committed before demand has been proven. Both statements are true simultaneously, which is why there is no universally optimal quantity.

What there is instead is a decision that should be made against two written inputs: your own demand assumption and a written quotation. Where either is missing, the quantity gets chosen by whatever feels safest in the meeting — and “safest” in that context usually means “smallest”, which quietly converts a volume decision into a margin decision.

6. Our Starting Point, and Its Boundaries

Rainbowdo reports a starting MOQ of 500 units. Do not transfer it as a universal rule to every product form or every customisation layer — it is a starting point, and the answer for a specific device should be confirmed rather than inferred from it.

The confirmation should run by product family, model, colour and configuration, logo, packaging, tooling, and any new design or test requirement. Our stated monthly capacity is 100,000 units, but the production window for your particular order and its component availability still need confirming separately.

This page deliberately publishes no MOQ ranges by product type. A range that is not tied to a current quotation is the kind of figure that gets repeated for years after the policy behind it has changed.

7. How We Return a MOQ Matrix

Rainbow Technology runs ODM and OEM programmes from our Shenzhen facility across masks, panels and worn formats. Send the matrix in your own columns and we will return it filled, including the rows where the answer is conditional:

• A minimum per form factor and per layer, rather than one number covering a range of products.
• Any separately driven minimum named — a packaging printer’s run, a flexible-substrate purchase — so the figure is traceable to its cause.
• Which parts are shared across forms and which are unique, with the traceability and variant control that sharing requires.
• Exceptions labelled as policy or one-off, so you know what to expect when you reorder.
• Sample and small-batch production from 500 units, with a stated capacity of 100,000 units per month; both figures depend on model, configuration, packaging and schedule, and are confirmed in a formal quotation.
• Compliance documentation matched to the exact model for your target market. Where a model holds a 510(k) record we provide the K-number so you can check its scope in the FDA’s public database; clearance is not the same as FDA approval, and the scope differs from model to model.
