LED Work Lights for Agricultural Machinery

A cab tractor working at night carries eight to twelve lamps in six positions, and each position asks for a different output and beam. The table pairs each position with the models most often specified there; the direct-fit models keep the original bracket and plug of the machine. All run on 9–32 V DC.

Harvesters and sprayers carry the same lamp family in different places. On a combine the light has to follow the crop from the header to the trailer alongside; on a sprayer it has to show the nozzles, which is why the boom lamps are blue.

The equipment behind the status table sits in our own factory, which is what lets us answer a specification line with a report rather than a promise.

Vibration table for broadband random profiles, run to the profile on your drawing: the header on a combine and the baler behind a tractor set the profile, and the report follows it.

Thermal shock chamber, salt spray chamber and dust chamber for the environmental lines: fertiliser and crop chemicals are covered by the salt spray and washdown lines of the specification rather than by a claim.

Photometric darkroom for beam pattern and intensity, so the flood, spot or cut-off on the drawing is measured rather than assumed.

EMC anechoic chamber for radiated emissions to CISPR 25, the test behind the class we quote per model in the documentation pack.

Reports from these tests are issued per model on request. Where a line calls for third-party type approval, such as ECE R10, we hold the approval for the four models in the first table and can route further models through the same laboratory. Road approval documents for headlamps and signal lamps are supplied on request.

A tractor roof now carries a GPS guidance receiver and an ISOBUS terminal within reach of the work lamps, and a lamp driver that passes on the bench can still put noise into the receiver beside it on the machine. That is why the EMC line matters more on a tractor than on most machines, and why we measure radiated emissions in our own chamber rather than reading them from a driver data sheet. Our guide on why E-marked lamps still interfere with radio and GPS explains what the class means in practice.

For the colour temperature that operators work under best, see why OEM work lamps are 5000–5700 K; for the amber warning lamps and the slow-moving-vehicle emblem on the road, see tractor hazard lights and the SMV emblem.
