5 Inch 50W High Power LED Work Light E-Mark Approved
The SLL-5050 is a 5 inch high power LED work light designed for vehicles and machinery that operate in extreme conditions, including agriculture, mining, construction, and roadwork. Five 10W CREE LEDs deliver 4000 lumens with a flood or spot beam option, ensuring visibility across the work zone or at distance. The die-cast aluminium housing with UV polyester powder coating resists corrosion, while IP68 sealing and overvoltage protection ensure reliable operation in rain, dust, and vibration. E-Mark and EMC CISPR25 CLASS 4 compliance allow use on public roads and in electrically sensitive environments.
- 50,000 hour lifespan reduces replacement frequency on machines that run long shifts
- E-Mark and EMC CISPR25 CLASS 4 compliance meet legal requirements for road use and electrical interference
- IP68 sealing prevents water and dust ingress during pressure washing or exposure to harsh environments
- 9 to 32V DC operation supports both 12V and 24V systems without changing part numbers
- Flood or spot beam options allow matching the light to the task—wide coverage or long reach
Where This Lamp Is Used
- Front and side work lighting on agricultural tractors and harvesters operating at night
- Auxiliary lighting on mining haul trucks and excavators exposed to dust and vibration
- Construction site lighting on cranes and loaders where dust and rain are frequent
- Roadwork vehicle lighting where E-Mark approval is required for public road compliance
- Fleet lighting on utility trucks and service vehicles with mixed 12V and 24V electrical systems
Who It Is For
- Distributors sourcing vehicle lighting for agriculture, mining, and construction markets
- Machinery OEMs fitting work lights on production lines with consistent mounting and electrical specs
- Fleet operators replacing halogen lights that fail under vibration and high duty cycles
- 4x4 accessory brands building private label work light ranges with beam flexibility
- Equipment dealers needing a single part number for both 12V and 24V vehicle fleets
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw excessive current from the vehicle’s electrical system
- Non-compliant auxiliary lights fail road inspections due to lack of E-Mark or EMC certification
- Lights with poor sealing fog up or fail after a few wash cycles in dusty or wet environments
- Narrow beam lights leave the near work area dark, while wide beam lights lack reach for distant visibility
- Inconsistent voltage tolerance causes premature failure in machines with unstable alternators
Technical Features
- Five 10W CREE LEDs with a total real power draw of 50W and 4000 lumens output
- Beam pattern selectable as flood or spot to suit different work tasks
- Die-cast aluminium housing with durable UV polyester powder coating for corrosion resistance
- Anti-UV polycarbonate lens with high impact and scratch resistance
- Overvoltage protection circuit to guard against electrical spikes from alternators
- Operating voltage range of 9 to 32V DC, compatible with 12V and 24V systems
- Operating temperature range from -40 to +85 degrees Celsius for extreme climate use
- IP68 sealing protects against water immersion and dust ingress
- Cable entry gland with sealed gasket to prevent moisture entry
- Mounting bracket designed for secure attachment to vehicle or machine surfaces

How This Lamp Is Built
Die casting of the aluminium housing and heat sink
Powder coating with UV polyester finish for outdoor durability
LED board assembly with CREE emitters and driver circuit
Lens bonding and gasket sealing to achieve IP68
Quality Control on This Model
- Photometric output verified in an integrating sphere
- Sealing tested to IP68 standard under pressure and immersion
- Vibration testing on a vibration test machine to simulate machine-mounted service
- Salt spray corrosion testing on housing and bracket for 1000 hours
- High and low temperature alternating humidity testing across -40 to +85 degrees Celsius
Customisation Options
- Beam pattern selection: flood or spot as standard options
- Deutsch connector or alternative cable length on request
- Private label logo on housing and printed cartons
- Mixed cartons combining this light with other SUNLITEC models for trial orders
- Alternative mounting bracket for specific machine fitment
How It Compares With the Alternatives
| Round 5 inch work lamp | The square body fits a standard mounting footprint but requires a flat surface for the bracket |
|---|---|
| Spot beam version of the same lamp | Flood covers the near work area evenly while spot reaches further ahead but leaves the machine edges dark |
| Lower voltage range lamp (10–30V) | Wider 9–32V range allows use on older or unstable electrical systems in heavy machinery |
How to Fit and Use It
- Leave a drip loop in the bare wire lead to prevent water from running into the gland
- Choose flood beam for near zone coverage or spot beam for long-distance visibility
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that degrade the anti-UV 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
Yes. The lamp is E-Mark approved and compliant with EMC CISPR25 CLASS 4, meeting legal requirements for road use.
