1. Separate emission technology from colour selection

An inventory line labelled amber LED leaves an important identification question open: what technology does the exact product documentation describe? Begin with the complete manufacturer part number and the actual supplied item. Loose emitters, populated boards and complete light engines need their own identifiers. A board's warehouse colour description should not replace the code of the individual product being classified.

Give emission technology its own field beside nominal colour and any available bin readings. The distinction is useful when two entries use similar colour language but their manufacturer descriptions identify different product types. Retain the original wording and source reference so a reviewer can see whether the classification came from a product document, a pack label or an unsupported warehouse abbreviation.

If technology identity is absent, leave that field unresolved while preserving the exact readings that are available. Do not turn a familiar colour name into a phosphor-converted or direct-colour conclusion. A mixed container may contain several supported identities, or material whose codes cannot yet be reconciled. Its total quantity should not silently become an offer for one selected technology.

2. Read the manufacturer's family-specific code notes

Lumileds' LUXEON Versat 2016 identification notes expressly distinguish phosphor-converted Amber from direct Colors in that product context. This supplies a concrete reason to retain the conversion descriptor independently from a colour selection. The notes are an example of a manufacturer's family-specific terminology, rather than evidence about the content of a seller's reel or a general decoder for every LED.

Match the complete offered identifier to the applicable family notes before using their wording. Preserve the manufacturer and product-family context when transcribing a description. If the seller has only a shortened marking or an internal stock number, ask for the record connecting it to the complete product code. Do not extend a partial match to units that have no corresponding pack or purchase reference.

Keep conversion identity distinct from the bin work covered by the related LED guide. Bin records can describe a selection within a documented product context; this review asks which emission technology the product itself represents. Resolving one field does not fill the other. A clear submission can therefore show supported technology, an unreadable bin and the quantity affected without inventing the missing selection.

3. Keep technology identity outside optical results

The manufacturer descriptor belongs to product identity. It is not a spectrum measured from the surplus material, a colour-matching report or evidence of current luminous output. Avoid presenting a catalogue description as if each offered unit had recently undergone optical assessment. The classification remains useful even when no lot-specific optical report is available, provided that limitation is explicit.

Where the owner has an existing report, retain its product identifiers, covered units, date and stated conditions. Explain whether it concerns individual samples, a particular pack or a larger assembly. A report for a light engine should not be assigned to loose emitters simply because its assembly list mentions the same family. Preserve what was actually reported rather than supplying an assumed result.

Record observable package or lens issues and known previous mounting separately from the technology field. These observations help describe the offered material, but they do not quantify its spectrum or optical performance. Likewise, original packing supports a packing description; it does not turn the identified technology into a current measurement. Keep unknown handling history visible when records do not establish it.

4. Offer technology-identified LED groups

Arrange the enquiry by complete product identity and supported technology, retaining pack references and any separate colour or bin fields. Keep unresolved conversion descriptions distinguishable from confirmed descriptions. If a group includes several technologies or unidentified items, state the mixture and identify which quantities the available records cover. This lets the recipient decide which part of the list can be assessed.

Use the general excess-stock list for actual quantity, location, ownership, release authority and packing information. Add the product-specific distinction here so the technical reviewer does not have to infer technology from a sales colour label. Supply permitted original references and explain conflicts between labels and records. Review of those conflicts may change the grouping, so update the affected lines when identification improves.

For an ICULTRA buyback enquiry, send the technology-supported groups and the explicit gaps through the stock-list route. Ask what identification evidence is needed for the unresolved material. A documented conversion descriptor does not promise a matched optical result, an accepted application or a purchase price. The recipient still needs to assess the particular offered groups and confirm any acceptance and commercial terms in writing.
