E-Mark ECE 20W 4 Inch LED Flood Work Light for Offroad Truck Tractor Agriculture SLL-13111
The SLL-13111 is a 4 inch flood work light designed for off-road trucks, tractors, and agricultural machinery that operate in harsh conditions. Two 10W Osram P9 LEDs deliver 1900 effective lumens across a wide flood beam, ensuring visibility across the entire work zone without hot spots. The die-cast aluminium housing is sealed to IP68 and carries ECE R10 and EMARK certification, which is required for machines used on public roads in Europe and other regulated markets.
- Two 10W Osram P9 LEDs provide 1900 effective lumens with a wide flood beam pattern, covering the full work area instead of a narrow hotspot
- IP68 sealing and a 35mm rotating bracket with 304 stainless steel side mounts allow installation in any angle and resist water ingress during pressure washing
- EMARK and ECE R10 certification ensure the lamp passes electromagnetic compatibility and road safety checks in regulated markets
- 10-30V DC operation runs the same part number on both 12V and 24V vehicle systems, reducing SKU count for fleet operators
- Die-cast aluminium housing with polycarbonate lens resists impact and maintains performance in high vibration environments
Where This Lamp Is Used
- Front and side work lighting on off-road trucks and tractors during night field operations
- Cab roof and hood lighting on agricultural machinery used after dark
- Auxiliary lighting on utility and service vehicles operating in remote or poorly lit areas
- Installation on tractors and harvesters where vibration and dust degrade standard sealed lamps
- Fleet maintenance lighting on agricultural and construction equipment where consistent visibility is critical
Who It Is For
- Distributors of 12V and 24V vehicle lighting needing one part number to serve both systems
- Machinery OEMs fitting work lights on production lines and requiring repeatable mounting patterns
- Fleet operators replacing halogen lights that fail under vibration and draw excessive current
- Agricultural and off-road accessory brands building a private label work lamp range
- Equipment dealers fitting lights on machines that must pass road inspection in Europe
Problems It Solves
- Halogen work lamps fail early under vibration and draw significantly more current than LED alternatives
- Cheap sealed lamps let water in through the cable entry and fog up after a few wash cycles
- Uncertified auxiliary lighting can be rejected at road inspection on machines used on public roads
- Narrow beam lamps light a small bright patch and leave the working edge of the machine dark
- Painted mild steel brackets rust within a season on machines that are washed daily or exposed to salt
Technical Features
- Two 10W Osram P9 LEDs with a real power draw of 20W and a maximum rating of 20W
- Flood beam pattern with a 1900 effective lumen output
- Semi-gloss black powder coating over the full housing and bracket
- 35mm rotating bracket with 3mm 304 stainless steel side mounting brackets for full-angle installation
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- EMC protected wiring and an operating window of -40 to +50 degrees Celsius

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 reproduce machine mounted service
- Salt spray corrosion testing on housing coating and stainless bracket
- High and low temperature alternating humidity testing across the -40 to +50 degrees Celsius window
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 a specific machine harness
- Mixed cartons combining this lamp with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Round 4 inch work lamp | The square body puts more LED area behind the same mounting footprint but needs a flat surface for the bottom bracket |
|---|---|
| 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 6 inch work lamp | Lower output but fits guard rails and cab pillars where a 6 inch body will not clear |
How to Fit and Use It
- Mount on a flat surface using the bottom bracket and check the 35mm bracket width against the machine bracket before drilling
- 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 working area 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 haze 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
The lamp is CE and RoHS compliant and carries EMARK and ECE R10 approval for electromagnetic compatibility and road safety.
