STEDI ST-04-G4-002 G4 Black Hybrid Spot Flood Work Light
STEDI ST-04-G4-002 G4 Black Hybrid Spot Flood Work Light
Combining the forward reach of a spot beam with the lateral spread of a flood, the STEDI G4 Black Hybrid delivers a smooth, homogeneous 3000-lumen beam extending 160 metres in length and 50 metres in width at 1 LUX.
Product Overview
The ST-04-G4-002 is STEDI's G4 Black Hybrid Work Light, powered by four CREE XP-L2 LEDs producing 4000 raw lumens and 3000 tested lumens through a hybrid beam pattern that combines spot and flood output in a single, smooth illuminated zone. The hybrid optic produces a homogeneous beam without the distinct spot centre and flood surround separation of conventional combo lights, reaching 160 metres in length and 50 metres in width at 1 LUX. This makes it a versatile single-light solution for applications requiring both forward reach and broad lateral coverage simultaneously, including 4WD auxiliary lighting, agricultural machinery, and work vehicle installation where neither a pure spot nor a pure flood would alone be adequate. The G4 is rated IP68 and IP69K for full waterproof and high-pressure wash-down protection, shock tested at 30Gs and vibration tested at 5Gs. CISPR 25 C3 certification confirms compatibility with sensitive in-vehicle communication systems. Compatible with both 12V and 24V systems, drawing 3.2A at 13.5V. The die-cast aluminium housing carries a premium AkzoNobel powder coat finish in black, with a polycarbonate lens, stainless steel hardware and bracket, and a STEDI protective cover included. Rated for 50,000 hours LED lifespan.
Features & Benefits
4x CREE XP-L2 LEDs at 40W Total: Four premium CREE XP-L2 LED emitters provide the optical efficiency and thermal management required for sustained high-output performance, producing 4000 raw lumens and 3000 independently tested lumens across the full hybrid beam pattern.
Hybrid Beam Combining Spot and Flood: The hybrid optic merges spot and flood output into a single, smooth, homogeneous illuminated zone without the distinct concentric rings typical of conventional combo beam lights. This provides usable illumination across both the near field and at distance simultaneously from a single light unit.
1 LUX at 160m Length and 50m Width: The hybrid beam reaches 160 metres in length and 50 metres in width at the 1 LUX threshold, providing significantly greater forward reach than a flood-only light while maintaining substantially broader lateral coverage than a spot-only light.
5700K White Light: The 5700K colour temperature produces a crisp, neutral white light that accurately renders colours in the working environment and provides high contrast across both the near field and mid-range illumination zones.
IP68 and IP69K Dual Rating: The dual IP68 and IP69K certification confirms the G4 is protected against continuous water immersion (IP68) and against high-pressure, high-temperature water jet wash-down (IP69K), covering the full range of conditions encountered in off-road, agricultural, marine, and industrial use.
CISPR 25 C3 Certified: CISPR 25 C3 electromagnetic compatibility certification confirms the G4 does not produce radio frequency interference that would affect in-vehicle communication systems including UHF, CB, GPS, or Bluetooth.
30G Shock and 5G Vibration Tested: Independently tested to withstand 30G shock loads and 5G sustained vibration, confirming structural and electrical integrity under the mechanical demands of off-road, agricultural machinery, and work vehicle applications.
12V and 24V Compatibility: Operates on both 12V and 24V electrical systems, making it compatible with passenger vehicles, light commercial vehicles, trucks, agricultural machinery, and industrial equipment.
Premium AkzoNobel Powder Coat Finish: The housing carries a premium AkzoNobel powder coat in black, known for its adhesion, hardness, and resistance to chipping, UV degradation, and chemical exposure in outdoor applications.
Die-Cast Aluminium Housing with Polycarbonate Lens: The die-cast aluminium housing provides structural rigidity and thermal management for the LED array, and the polycarbonate lens provides impact resistance and optical clarity throughout the rated 50,000-hour lifespan.
Stainless Steel Hardware, Bracket, and STEDI Cover Included: Stainless steel mounting hardware and bracket are included for a complete, corrosion-resistant installation, and a STEDI protective cover is supplied for storage or transport.

Goes Well With
The ST-04-G4-002 is well suited to 4WD and work vehicle installations where a single light needs to provide both forward reach and lateral coverage without dedicating separate lights to spot and flood duties. It pairs naturally with other STEDI G4 lights in the same range for multi-light setups, and with STEDI light bars and driving lights where the hybrid beam fills the mid-range gap between a long-range spot and a close-range flood. A STEDI or compatible wiring harness with switch is recommended for clean vehicle installation.
Frequently Asked Questions
What makes a hybrid beam different from a standard combo beam?
A standard combo beam uses separate spot and flood optics within the same housing, typically producing a bright central spot surrounded by a wider flood ring. The transition between the two zones can be visible as an uneven pattern with a concentrated hotspot and lower-intensity surround. The G4 Hybrid's optic blends spot and flood output into a single, smooth, homogeneous illuminated zone without distinct rings or zones, providing a more natural and comfortable beam profile for both driving and work applications.
How does the G4 Hybrid compare to the G4 Flood and G4 Ultra Flood in the same range?
All three G4 variants use the same 4x CREE XP-L2 LEDs, 40W total power, 3000 tested lumens, housing, and certifications. The G4 Ultra Flood (ST-04-G4-004) produces an 80° beam reaching 42m at 1 LUX and 37m wide, optimised for close-range area illumination. The G4 Flood (ST-04-G4-003) produces a 60° beam reaching 81m at 1 LUX and approximately 40m wide, balancing near-field coverage with moderate forward reach. The G4 Hybrid (ST-04-G4-002) produces a combined spot and flood beam reaching 160m in length and 50m in width at 1 LUX, providing the greatest forward reach of the three while maintaining broad lateral coverage.
What does IP69K add to IP68 protection?
IP68 certifies the light is sealed against continuous water immersion at specified depth and duration. IP69K is an additional certification covering high-pressure and high-temperature water jet wash-down, encountered when hosing down agricultural machinery, work vehicles, and ATVs. The G4's dual IP68 and IP69K rating confirms it is protected against both scenarios.
What does CISPR 25 C3 mean for vehicle installations?
CISPR 25 is an international standard measuring radio frequency emissions produced by vehicle components. C3 is the highest performance class within CISPR 25, confirming the G4 produces minimal electromagnetic interference that could affect communication systems including AM/FM radio, GPS, Bluetooth, UHF CB, and mobile data.
Is the G4 Hybrid suitable for use as a primary auxiliary driving light?
The G4 Hybrid's 160-metre 1 LUX reach makes it more useful as an auxiliary driving light than the flood and ultra-flood variants, while its 50-metre width provides considerably broader coverage than a conventional spot light. For applications requiring maximum long-distance throw beyond 160 metres, a dedicated spot or long-range driving light would be more appropriate. The G4 Hybrid is best suited to work, off-road, and auxiliary lighting roles where a balanced beam from a single light is the priority.
