Great Whites GWB5094 Attack 9 LED Driving Light Bar 45W

Great Whites GWB5094 Attack 9 LED Driving Light Bar 45W

Combining CREE XTE-HE LEDs with cutting-edge iris-reflector technology, the Great Whites Attack GWB5094 delivers 3300 effective lumens and a 1 LUX reach of 320 metres in a compact 0.95kg light bar built for the harshest Australian off-road conditions.

Product Overview

The GWB5094 is Great Whites' 9-LED Attack Series driving light bar, engineered to outperform the equivalent Gen2 product in output, weight, and durability. Nine CREE XTE-HE LEDs produce 4500 raw lumens and 3300 effective lumens at 6000K, a colour temperature that replicates the midday sun to reduce driver fatigue and eye strain on long-distance drives. The proprietary iris-reflector technology combines with the CREE emitters to project a powerful forward beam reaching 1 LUX at 320 metres while simultaneously providing lateral illumination of roadside hazards, eliminating the tunnel-vision effect of pure spot beams without sacrificing forward throw. At 335mm in length and 0.95kg, the GWB5094 is significantly lighter than equivalent Gen2 units while retaining the structural toughness expected from a professional-grade driving light.

The marine-grade aluminium housing and polycarbonate lens are rated IP68 and IP69K for full submersion resistance to 3 metres and high-pressure wash-down protection. The integrated Gortex valve allows the internal cavity to breathe and equalise pressure, preventing condensation build-up inside the light during temperature cycling in the field. Vibration resistance is rated to 21 Grms, covering the full range of off-road driving conditions. Operating across 10-32V, the GWB5094 is compatible with both 12V and 24V vehicles. Connection is via the DT04-2P connector. Backed by a comprehensive 3-year warranty.

Features & Benefits

CREE XTE-HE LEDs for Maximum Lumens per Watt: Nine CREE XTE-HE emitters deliver 4500 raw lumens and 3300 effective lumens at 45W total draw, producing a higher lumens-per-watt ratio than previous generation LEDs and significantly outperforming equivalent HID or halogen driving lights at the same power consumption.

Iris-Reflector Technology for Balanced Beam Pattern: The cutting-edge iris-reflector combines with the CREE emitters to push light both down the road and to the periphery simultaneously, providing 1 LUX at 320 metres of forward throw alongside ample illumination of road edges and roadside hazards without requiring a separate flood light.

1 LUX at 320m: The beam reaches 320 metres at the 1 LUX threshold, providing genuine long-range forward illumination suited to high-speed rural and outback driving where early hazard detection is critical to driver safety.

6000K Colour Temperature: The 6000K output replicates the colour temperature of the midday sun, providing a natural white light that reduces driver fatigue and eye strain on long drives and produces accurate colour rendering of the road environment.

Marine-Grade Aluminium Body: The housing is constructed from marine-grade aluminium, providing a lightweight yet structurally robust enclosure that resists corrosion from salt air, road spray, mud, and water exposure in marine and off-road environments.

IP68 and IP69K Dual Rating: Full submersion protection to 3 metres (IP68) combined with high-pressure, high-temperature wash-down resistance (IP69K) ensures the GWB5094 performs reliably regardless of water crossings, mud immersion, or pressure cleaning after off-road use.

Gortex Valve for Condensation Prevention: The integrated Gortex valve allows the light's internal cavity to breathe and equalise pressure as temperature changes, preventing the condensation build-up that can degrade LED and reflector performance over time in sealed driving light housings.

21 Grms Vibration Resistance: Tested to 21 Grms vibration resistance, confirming structural integrity across corrugated dirt roads, rocky terrain, and the sustained vibration environments typical of serious off-road use.

10-32V Compatibility: Wide voltage range operation from 10V to 32V makes the GWB5094 compatible with both 12V and 24V electrical systems across passenger 4WDs, trucks, and commercial fleet vehicles.

Lighter Than Gen2 Equivalent: The Attack range delivers greater output than the equivalent Gen2 light in a significantly lighter package, reducing mounting stress and overall vehicle weight without compromising the durability expected from a Great Whites product.

3-Year Warranty: Covered by Great Whites' comprehensive 3-year warranty, reflecting the brand's confidence in the long-term durability of the Attack range in real-world use.

Technical Specs

Goes Well With

The GWB5094 is suited to roof racks, bull bars, and A-pillar mounting positions on 4WDs and light commercial vehicles where maximum forward throw at highway and outback driving speeds is the priority. Its compact 335mm length makes it an effective single or paired light solution across a range of vehicle configurations. A suitable wiring harness with relay and switch is recommended for clean installation, and the DT04-2P connector is compatible with standard Great Whites and aftermarket wiring loom solutions. For vehicles requiring broader near-field flood coverage alongside the Attack light bar's forward throw, pairing with a dedicated flood or combo beam light provides a complete auxiliary lighting solution.

Frequently Asked Questions

How does the GWB5094 compare to the Great Whites Gen2 equivalent?

The Attack range was developed to outperform the Gen2 equivalent in light output, reduce overall weight, and improve visual design, while maintaining the same standard of durability. The GWB5094 delivers greater effective lumens and longer 1 LUX distance than the equivalent Gen2 9-LED bar in a lighter housing, making it the preferred choice for 4WD enthusiasts where performance and weight are both priorities. The Gen2 range remains a strong option for commercial fleet operators.

What does the Gortex valve do, and why does it matter?

The Gortex valve is a breathable membrane integrated into the light housing that allows air to pass in and out of the sealed internal cavity as temperatures change, equalising internal pressure without allowing water or dust ingress. Without this valve, temperature cycling between cold night air and hot daytime operation creates pressure differentials that can force moisture into even well-sealed housings over time. The Gortex valve eliminates this mechanism, protecting the LED array and reflector surfaces from condensation damage throughout the light's service life.

What does 21 Grms vibration resistance mean in practice?

Grms (root mean square gravity) is a standard measurement of vibration intensity. A rating of 21 Grms covers the sustained vibration loads experienced on corrugated outback roads, rocky 4WD tracks, and high-speed unsealed driving, confirming the GWB5094's structural and electrical integrity under the conditions it is designed for. This rating is significantly more demanding than standard automotive vibration testing.

Is the GWB5094 compatible with 24V vehicles such as trucks?

Yes. The 10-32V operating voltage makes the GWB5094 directly compatible with 24V electrical systems used in trucks, heavy vehicles, and commercial fleet applications without requiring a voltage converter or separate 24V variant.

Why is 6000K colour temperature important for driving light safety?

6000K approximates the colour temperature of the midday sun, producing a neutral white light that the human visual system processes efficiently over extended periods. Warmer yellow-toned lights (lower Kelvin) reduce colour discrimination and can increase eye strain on long drives, while very blue-shifted lights (higher Kelvin) can reduce contrast in fog or dust. The 6000K output of the GWB5094 is widely considered the optimal balance for driving light applications from a driver fatigue and hazard recognition perspective.
