E-Mark 5.5 Inch 12V/24V CREE LED Work Light for Car 4x4 Offroad SLL-55120
The SLL-55120 is a 5.5 inch flood work light designed for off-road vehicles and 4x4s that operate in harsh conditions with high vibration, dust, and water exposure. Twenty-four 5W CREE XPG2 LEDs deliver approximately 10128 lumens in a 50-degree flood beam, providing even illumination across the immediate work zone without creating a narrow hot spot. The die-cast aluminium housing and 304 stainless steel bracket ensure durability, while IP68 sealing and ECE R10 approval make it suitable for use on vehicles that may be driven on public roads.
- 24 x 5W CREE XPG2 LEDs deliver approximately 10128 lumens in a 50-degree flood beam for wide, even coverage
- IP68 sealing prevents water ingress during pressure washing or submersion
- ECE R10 and EMARK certification ensure compliance with electromagnetic compatibility standards for road use
- 304 stainless steel bracket resists corrosion on vehicles exposed to salt, mud, or cleaning chemicals
- 10-30V DC operating range allows the same part number to be used on 12V and 24V systems, reducing SKU count
Where This Lamp Is Used
- Front and side work lighting on 4x4s and off-road utility vehicles operating at night in remote areas
- Cab roof and hood lighting on construction and mining vehicles where vibration and dust are constant
- Auxiliary lighting on emergency service vehicles and mobile equipment used in wet or muddy conditions
- Fleet vehicles that require consistent lighting across multiple vehicle types with different electrical systems
- Mounting on the front bumper or grille of a 4x4 where a wide flood beam improves visibility around the vehicle
Who It Is For
- Distributors of off-road vehicle lighting needing one part number for both 12V and 24V fleets
- 4x4 accessory brands building a private label work light line with proven road compliance
- Machinery OEMs integrating work lights into production line builds with consistent mounting patterns
- Fleet operators replacing halogen lights that fail under vibration and draw excessive current
- Equipment dealers fitting lighting on machines used in agriculture, mining, or construction
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw more current than LED alternatives
- Cheap sealed lights fail after a few wash cycles due to poor cable gland sealing and internal fogging
- Uncertified auxiliary lights may fail an ECE R10 or EMARK check during vehicle inspection
- Narrow beam lights leave the edges of the work zone dark, increasing risk during night operations
- Painted mild steel brackets rust within months on machines washed daily with water or chemicals
Technical Features
- Twenty-four 5W CREE XPG2 LEDs with a total light output of approximately 10128 lumens
- Flood beam pattern with a 50-degree spread for even illumination across the immediate work area
- Bare wire lead of 40cm as standard, with Deutsch connector available on request
- Operating voltage range of 10 to 30V DC, compatible with both 12V and 24V systems
- Operates reliably in temperatures from -40 to +50 degrees Celsius
- EMC protected wiring and sealed cable entry gland to prevent electrical interference

Lens bonding and gasket sealing
Quality Control on This Model
- Photometric output verified in an integrating sphere
- Sealing verified against the IP68 rating before shipment
- Vibration testing on a vibration test machine to simulate real vehicle mounting conditions
- Salt spray corrosion testing on housing coating and stainless steel bracket
- High and low temperature alternating humidity testing across the -40 to +50 degrees Celsius range
Customisation Options
- Deutsch DT 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 for integration with a specific machine harness
- Mixed cartons combining this lamp with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Halogen work lamp of similar output | Draws less than half the current at 12V and survives vibration that destroys a filament |
|---|---|
| Round 5.5 inch work lamp | The square body allows more LED area behind the same mounting footprint but requires a flat surface for the bracket |
| Spot beam version of the same lamp | Flood covers the near work zone evenly while spot reaches further ahead but leaves the machine edges dark |
| Larger 6 inch work lamp | Lower output but fits in tight spaces like bumper grilles where a 6 inch body would not clear |
How to Fit and Use It
- 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 area close to the machine and use a spot lamp separately for distance
- Clean the PC lens with water and a soft cloth only, as solvents may damage the anti-scratch 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 10 to 30V 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
Yes. The lamp is CE, RoHS, EMARK and ECE R10 certified, which covers electromagnetic compatibility and road use compliance.
