Supplier product reference · reviewed 18 October 2026
A four- and six-emitter family consolidated across two sources, with version-specific optical and protection questions.
Published identification
Supplier-published entries. Ratings and configuration still require current documentation.
The ST4 and ST6 official pages share a two-model table, so they are presented as one family. The supplier identifies four- and six-emitter variants and lists different approval-class names by column. Those names are kept as attributed source information, not transferred from one variant to the other or treated as independently verified approvals.
The prepared illustration follows the four-optic ST4 source picture. It is not a depiction of ST6. The ST6 body mentions IP67 or IP69K while the shared table says IP67, so the required environmental documentation must identify the offered revision. A 13mm thickness statement does not provide a complete drawing or fixing pitch for either variant.
Procurement checklist
Keep the item identity, physical version and supply scope together. Use the questions alongside the published specifications when preparing a sourcing brief.
Specify the model, emitted colour or split-colour arrangement and required control functions. Request the matching sheet and full dimensional drawing. A shared source family is not evidence that the four- and six-emitter versions have the same mounting envelope, control revision or optical output.
Ask for pattern, synchronisation and alternation documentation for the selected model, with lead length and termination identified. Confirm the screw kit and any backing components. Source wire-colour references are not used here as a wiring instruction or proof of compatibility with another warning system.
Request current documents for the actual model and colour, including clarification of the IP67/IP69K body wording. The source’s approval-class columns must not be exchanged between variants. Published sample or bulk delivery times are not used as current availability commitments; obtain a written quotation for present supply scope and lead time.
A catalogue input range does not establish compatibility with an electric forklift’s traction battery or accessory circuit. Ask the equipment supplier to identify the documented accessory supply, control interface and intended application. The truck model, serial number and installed-component record remain important even when a lamp or controller looks similar.
Two official sources support an ST4/ST6 family. Complete dimensions, control interoperability, protection scope, approval, present availability and installed warning performance remain unverified.
This reference is neither a quotation nor a stock, delivery or authorisation commitment. Request a current written proposal from the quoting entity. Preserve the item reference, quantity, destination and included accessories in that proposal so that changes of configuration remain visible.
