The STEDI ST3K 51.5" Slim LED Light Bar delivers strong long-range and wide-beam performance from a low-profile housing designed for installations where mounting space is limited. With an overall height of just 51mm without the side brackets and 63mm with the brackets fitted, it can be installed on suitable bull bars, grilles, roof racks and canopies without the bulk of a conventional double-row light bar.

Using 50 Osram Oslon LEDs, the ST3K produces 10,250 effective lumens with a peak intensity of 608,000 candela. Its combination beam uses dedicated flood and spot reflectors to provide useful road-edge illumination together with a concentrated central beam reaching 1 lux at 778 metres.

This product is supplied unfitted with the light bar, stainless-steel mounting hardware and a 12V high-beam wiring kit ready for installation.

Slim, Low-Profile Construction

The ST3K is designed to deliver substantial lighting performance while occupying minimal vertical space. The light bar body measures only 51mm high, increasing to approximately 63mm with the supplied side brackets installed.

This slim profile makes it suitable for installations where a larger double-row light bar may obstruct airflow, interfere with surrounding components or appear too prominent on the vehicle.

Flood and Spot Combination Beam

The reflector layout combines long-range projection with useful peripheral coverage:

  • 30 spot reflectors with a focused 5.8-degree beam
  • 20 flood reflectors positioned across both ends of the light bar
  • 50-degree flood spread for road-edge and shoulder visibility

This configuration creates a strong central beam for seeing further down the road while also directing light towards the surrounding driving area. It is suited to highway travel, remote touring and off-road driving where both distance and width are important.

Long-Range Lighting Performance

The ST3K 51.5" light bar produces a peak intensity of 608,000 candela and reaches 1 lux at 778 metres. Its effective output of 10,250 lumens provides substantial forward illumination without requiring a tall or bulky housing.

Photometric Performance

  • 10 metres: 6,052 lux
  • 50 metres: 242 lux
  • 100 metres: 60 lux
  • 200 metres: 15 lux
  • 778 metres: 1 lux

5700K White Light

The LEDs produce a 5700K white colour temperature, delivering clear definition of the road, track and surrounding terrain. The neutral-white output is designed to provide strong visual contrast during night driving.

Efficient Pure-Drive Circuitry

STEDI's Pure-Drive circuit design directs approximately 97% of the input power to the LEDs. The light bar draws approximately 11.2 amps at 13.6 volts and is compatible with electrical systems operating between 10 and 30 volts DC.

Built for Harsh Conditions

The ST3K uses an aluminium extrusion and cast housing finished with a UV- and abrasion-resistant polyester powder coat. Its GE Lexan lens and sealed construction are designed for demanding touring, commercial and off-road environments.

  • IP68-rated against dust and water ingress
  • Waterproof to a depth of up to 3 metres
  • Pressure-equalisation vent helps protect against moisture and contaminants
  • Environmentally sealed DTP electrical connector
  • Protected against electromagnetic and radio-frequency interference
  • Operating temperature range from -40°C to +50°C
  • Powder-coated stainless-steel mounting brackets
  • Stainless-steel fasteners

Flexible Mounting Options

The slim housing makes the light bar suitable for a wide range of installations, including compatible:

  • Bull bars
  • Front grilles
  • Roof racks
  • Canopies
  • Ute trays
  • Commercial and service vehicles

Final compatibility depends on the available mounting width, supporting structure, vehicle clearance and wiring arrangement.

High-Beam Wiring Kit Included

The supplied 12V Quick-Fit wiring kit includes a relay, wiring loom, on/off switch and H4 and HB3 high-beam adapters. The harness includes integrated electronics intended to support connection with a range of modern vehicle high-beam systems.

A different or vehicle-specific piggyback adapter may be required where the supplied H4 or HB3 adapters do not match the vehicle.
