Supplier product reference · reviewed 17 October 2026
Separate the regular, heated and heated-plus-dimming references. Do not treat the entire S40 family as a heated or dimmable lamp.
Published identification
Supplier-published entries. Ratings and configuration still require current documentation.
The source’s heated-and-dimmable title covers three table references with different functions. NW-S40 is listed as regular, NW-S40H as heated and NW-S40D as heated with dimming. Preserving that distinction prevents optional capabilities from being attributed to the basic version.
The prepared reference retains the square four-optic front and triangular-style mounting assembly visible in the supplier image. That common appearance does not identify whether a pictured unit has heating or dimming circuitry. Request the label and current ordering code rather than choosing a version from the front view.
Procurement checklist
Keep the item identity, physical version and supply scope together. Use the questions alongside the published specifications when preparing a sourcing brief.
Ask the supplier to identify the complete reference and confirm heating and dimming separately. Obtain the function and control documentation for that version. A family title or common housing is not evidence that a regular S40 includes either optional capability.
The source lists a three-pin DT connection. Ask for the exact mating reference and version-specific interface document, including the electrical-demand conditions for the supported functions. Pin count alone cannot establish wiring or compatibility with an existing machine harness.
Request spot or flood identification, the corresponding optical information and the bracket drawing. Confirm whether mounting accessories are included and obtain evidence for any vibration requirement that matters to the procurement. A bracket shape is not a verified vibration-test result.
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.
No cold-weather safety benefit, heating performance, radio-interference rating, environmental protection or durability claim is independently verified. The source’s performance and approval statements remain supplier claims. No machine-specific fit or installation acceptance is established.
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.

Document comparison · 19 October 2026
The catalogue NW-E40 photograph closely resembles the four-reflector lamp and triangular mounting hardware on the NW-S40 family webpage. Matching photographs and envelope dimensions are useful identification clues, but they do not establish that the codes refer to the same revision, functions or connector pin assignment.
Keep the full suffix, heat and dimming functions, input limits, connector and drawing together in a quotation. Ask the supplier to explain the NW-E40 versus NW-S40 naming and the 4000 versus 4800 lm entries in writing. Neither the shared 40 W figure nor the photograph confirms interchangeability. The different NW-S4 product should not be folded into this family merely because it also uses four optics and a 40 W description.
These are supplier-published descriptions, not independently tested ratings, confirmed inventory, authorization or vehicle compatibility. Keep the source and exact offered configuration attached to any purchasing decision. Existing supplier contact and procurement routes remain available above.
