6 Inch 18W Offroad Flush Mounting LED Work Light
The SLL-6031 is a 6 inch flush mounting LED work light designed for off-road vehicles and heavy machinery that operate in harsh environments with dust, water, and vibration. Six 3W CREE LEDs deliver 1440 effective lumens in a flood beam pattern, providing even illumination across the immediate work zone without creating a narrow hot spot. The die-cast aluminium housing with UV resistant polyester powder coating and IP68 sealing ensures long-term durability under pressure washing and salt exposure. ECE-R23 and ECE-R10 approvals confirm compliance with European vehicle lighting standards, which is required for machines used on public roads.
- Flood beam spreads 1440 effective lumens evenly across the work area instead of a narrow bright spot
- IP68 sealing and a robust cable entry gland prevent water and dust ingress during pressure washing
- ECE-R23 and ECE-R10 approvals ensure the light passes electrical and road safety inspections in Europe
- 9–32V DC operation allows use on both 12V and 24V off-road vehicles without changing part numbers
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged high load
Where This Lamp Is Used
- Front and side work lighting on off-road vehicles and utility trucks operating in remote or low-light conditions
- Cab and hood lighting on excavators and loaders during night shift operations
- Auxiliary lighting on cranes and engineering vehicles where vibration damages standard sealed lamps
- Flush mounting on vehicle roofs and guard rails where space is limited and surface clearance is minimal
- Lighting on fleet vehicles used in mining, agriculture, and construction where dust and moisture are constant
Who It Is For
- Distributors of off-road vehicle lighting needing one part number for both 12V and 24V systems
- Machinery OEMs integrating flush-mounted work lights during production with consistent mounting patterns
- Fleet operators replacing halogen or low-lumen LED lamps that fail under vibration or heat
- 4x4 accessory brands developing a private label work light range with road-legal certification
- Equipment dealers fitting lights on machines that must pass European road inspection standards
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw excessive current from the vehicle’s electrical system
- Cheap sealed lights allow water entry through the cable gland and fog up after a few wash cycles
- Uncertified auxiliary lights can be rejected during ECE road inspections on machines used on public roads
- Narrow beam lights illuminate only a small area ahead, leaving the sides and edges of the machine in shadow
- Painted mild steel brackets corrode rapidly in wet or salty environments, leading to bracket failure
Technical Features
- Six 3W CREE LEDs with a total real power draw of 18W and a maximum rating of 20W
- Flood beam pattern with 1440 effective lumens output

- Sealing verified against the IP68 rating before shipment
- Vibration testing on a vibration test machine to simulate machine-mounted service
- Salt spray corrosion testing on housing coating and internal components
- High and low temperature alternating humidity testing across the -40 to +60 degrees Celsius range
Customisation Options
- Deutsch connector instead of the standard 40cm bare wire lead
- Spot beam optics in place of the flood pattern
- Private label logo on the housing and printed carton
- Alternative cable length to match a specific machine harness
- Mixed cartons combining this lamp with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Round 6 inch work lamp | The flush mounting design fits flush with the surface, saving space and reducing wind resistance on vehicles |
|---|---|
| Spot beam version of the same lamp | Flood covers the near working area evenly while spot reaches further ahead but leaves the machine edges dark |
| Larger 8 inch work lamp | Lower output but fits flush on narrow surfaces where a larger body would interfere with adjacent parts |
How to Fit and Use It
- Mount flush on a flat surface using the 6 inch diameter footprint and ensure the surface is clean and dry before installation
- Leave a drip loop in the 40cm lead so water runs away from the gland rather than into it
- Aim the flood beam at the immediate work zone close to the machine and use a spot lamp separately for distance
- Clean the PC lens with water and a soft cloth only, since solvents will degrade the anti-reflective coating
Questions About This Model
Can I order a sample before placing a bulk order
Yes. Sample orders are welcome and mixed samples of different models in one shipment are accepted.
What is the lead time
Sample orders normally take around 3 to 7 working days. Bulk lead time depends on the model and the quantity ordered.
Do you have a minimum order quantity
There is an MOQ for standard orders, but smaller orders are also accepted, which suits distributors testing a new model.
How is the lamp shipped
Samples usually go by DHL, UPS, FedEx or TNT in around 4 to 7 days. Bulk orders ship by air in about 7 to 15 days or by sea in about 15 to 30 days.
Will this lamp work on both 12V and 24V machines
Yes. The operating range is 9 to 32V DC, so the same part number can be fitted to 12V and 24V vehicles.
Can you supply the lamp with our own brand
Yes. OEM and ODM service is available, including a private label logo on the housing and printed cartons.
Is it approved for road going machines
The lamp is CE and RoHS compliant and carries ECE-R23 and ECE-R10 approvals for vehicle lighting and electromagnetic compatibility.
