A brand preference is a useful starting point for a lighting enquiry. It is not a complete component specification. Two COBs from the same brand can have different dimensions and electrical requirements, while two drivers with similar power labels can have different output characteristics. The buyer needs a route from the preferred brand to an identified, agreed assembly.
This guide explains that route for housing Kit and Full Set buyers. It covers how to read the product's candidate brand pool, what information to request for the proposed COB and driver, and how those choices become a recorded bill of materials through BOM Lock.
Read the brand pool for the selected product
Use the pool shown for the actual model. On the current KF-TL528 family, the recorded COB candidates are Philips, CREE, Citizen and Bridgelux. The driver candidates are Philips, Lifud and Eaglerise. These lists distinguish the two component roles; they do not mean that every possible pairing has been confirmed for every requirement.
Philips appears in both lists, so the enquiry should say whether the preference concerns the COB, the driver or both. Citizen and Bridgelux appear in the COB pool, while Lifud appears in the driver pool. Treat each selection as a request to identify a suitable component within the proposed configuration, not as a substitute for the component model.
Handle an Osram requirement explicitly
If the project brief names Osram, include the required component role and model reference in the enquiry. Osram is not listed in the current 528 product pool. Its suitability and availability therefore need explicit confirmation during quotation. Do not interpret an article's discussion of a brand as an added product option or an assurance that the requested part fits.
The same discipline applies when a product has no recorded pool. An empty field leaves the component choice open for discussion; it does not authorise an assumption about the supplied brand. Keep the requested brand and the confirmed component separate in your purchasing notes until the quotation identifies what will be supplied.
Specify the COB beyond its brand name
Ask for the exact COB model and its relevant documentation. The review should cover the module dimensions, light-emitting area, mounting arrangement, electrical requirements and requested colour specification. The holder and reflector must be considered with that source. A mechanically similar replacement may still change how the light enters the optical system.
State the required CCT and colour-rendering information in the same request. Where colour appearance is important, identify the merchandise or finish that will be assessed. Avoid using a broad brand preference as a performance claim. The COB LED explainer separates packaging terminology from the light and assembly properties that need individual confirmation.
Check the driver against the proposed light source
Review the driver's output type, output current, operating voltage range and power limits against the selected COB's requirements. Check the intended input supply and the operating conditions as well. A nominal power rating only answers part of this review. The proposed driver also needs to fit the mechanical arrangement and operate within its documented conditions.
If the project requires dimming, name the control method and the control equipment. Ask for confirmation of that specific combination. A brand-level request such as a Philips or Lifud driver does not identify the control behaviour of the selected model. Record the exact part reference and any settings that form part of the agreed configuration.
Make the Kit and Full Set responsibilities clear
The housing Kit is available for direct supply. Under the standard scope, the buyer provides the COB module, LED driver and COB holder for their own integration. That gives the buyer control over component selection, but the interfaces between the selected parts still need review. Read any model-specific scope note alongside the standard description.
For a Full Set upgrade, provide the component preferences and complete-luminaire requirements for quotation. The proposed COB and driver are then part of the configuration to be confirmed. The housing Kit guide explains the two supply paths. State the route clearly so a housing quotation is not mistaken for an agreement to supply a particular light engine.
Turn preferences into a bill of materials
A bill of materials, or BOM, identifies the parts agreed for the order. It should connect the housing model to the selected COB and driver rather than leaving those names in an unstructured message. Where an order contains more than one Full Set model, each line needs its own component record so the choices cannot be confused.
KAIFON's Full Set quotation workflow records COB brand and model, driver brand and model, and batch or revision for each applicable order line. These five details are required when the payment link is generated. BOM Lock preserves the agreed component snapshot with the order line, alongside its product identity and quantity.
Understand what BOM Lock confirms
BOM Lock makes the agreed component selection traceable within the order. It does not, by itself, prove that a light-output target, control combination or beam requirement has been tested. Keep the relevant technical information and any sample approval with the component record. Each answers a different question about the configuration being purchased.
If a proposed component changes before agreement, review the affected interfaces and performance requirements again. Record the revised proposal clearly instead of relying on the fact that the brand stayed the same. For repeat purchasing, quote the earlier model and BOM reference and request confirmation of the proposed configuration rather than assuming it will be identical.
Prepare an enquiry that can become a clear quotation
List the housing model, beam, colour, mounting arrangement and supply path first. Add the requested COB and driver brands, any mandatory model references, the CCT and colour-rendering requirements, and the control method where relevant. Separate fixed requirements from preferences that can be discussed. Include the intended operating conditions that affect component selection.
The COB spotlight selection guide provides the wider selection sequence. Use the product's current pool to frame the component discussion, then send the selected models and requirements through the quotation enquiry. The useful outcome is an identified configuration with a recorded BOM, rather than a list of brand names alone.
