5.5 Inch 30W 12/24V CREE LED Flood Work Light for Tractor Agriculture Truck SLL-16116
The SLL-16116 is a 5.5 inch flood work light designed for tractors, agricultural trucks, and other heavy machinery that operate in dusty, wet, or vibration-heavy environments. Six 5W CREE XPG-2 LEDs deliver 4620 raw lumens in a 40° flood beam pattern, providing even illumination across the immediate work zone without creating a hot spot. The die-cast aluminium housing with 304 stainless steel brackets resists corrosion, while IP67 sealing and a military-grade breather vent prevent internal pressure build-up and water ingress during frequent washdowns.
- 6 x 5W CREE XPG-2 LEDs deliver 4620 raw lumens in a 40° flood beam for even coverage across the work area
- IP67 sealing and a military breather vent prevent water entry and internal condensation during pressure washing
- 304 stainless steel brackets and screws resist rust on machines exposed to salt, fertiliser, or frequent cleaning
- 10-30V DC input allows the same part number to be used on 12V and 24V fleets, reducing SKU complexity
- Overheat and reverse polarity protection prevent damage from electrical faults common in vehicle systems
Where This Lamp Is Used
- Front and side work lighting on tractors and harvesters during night field operations
- Cab and hood lighting on agricultural trucks used in wet or dusty conditions
- Auxiliary lighting on utility and service trucks that require consistent illumination during roadside repairs
- Work area lighting on tipper trucks and dump bodies where vibration and dust degrade standard lamps
- Lighting on machinery used in farming, forestry, or construction where daily washdowns are routine
Who It Is For
- Distributors of 12V and 24V vehicle lighting needing a single part number for both systems
- Machinery OEMs integrating work lights into production lines with consistent mounting patterns
- Fleet operators replacing halogen or low-lumen LED lamps that fail under vibration or moisture
- Agricultural equipment brands building a private label work light range with proven durability
Problems It Solves
- Halogen work lamps burn out quickly under vibration and draw excessive current from vehicle electrical systems
- Cheap sealed lamps fail after a few wash cycles due to internal pressure build-up or poor sealing
- Narrow beam lamps leave the near edge of the machine in shadow while over-illuminating distant areas
- Mild steel brackets rust within weeks on machines washed daily with water or chemical solutions
- Unprotected LED drivers fail due to reverse polarity or overheating in unregulated vehicle circuits
Technical Features
- Six 5W CREE XPG-2 LEDs with a total power draw of 30W and a raw lumen output of 4620 lm
- Flood beam pattern with a 40° spread for even illumination across the immediate work zone
- Anti-UV, unbreakable polycarbonate lens over a die-cast aluminium heat sink
- Semi-gloss black UV-resistant polyester powder coating over the full housing
- Integrated military breather vent to equalize pressure and prevent seal failure
- Reverse polarity and overheat protection built into the driver circuit
- Operating voltage range of 10-30V DC, compatible with 12V and 24V vehicle systems
- Operating temperature range of -40 to +60 degrees Celsius
- Bare wire lead of 40cm as standard, with Deutsch connector available on request

Lens bonding and gasket sealing
Quality Control on This Model
- Photometric output verified in an integrating sphere
- Sealing verified against the IP67 rating before shipment
- Vibration testing on a vibration test machine to simulate machine-mounted service
- Salt spray corrosion testing on housing coating and stainless steel brackets
- High and low temperature alternating humidity testing across the -40 to +60 degrees Celsius window
Customisation Options
- Deutsch DT connector instead of the standard 40cm bare wire lead
- Alternative beam pattern (spot or wide flood) on request
- Private label logo on the housing and printed carton
- Custom 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 5.5 inch work lamp | The square body provides more LED area behind the same mounting footprint but requires a flat mounting surface |
|---|---|
| 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 tight spaces like cab pillars and guard rails where a 6 inch body would not clear |
How to Fit and Use It
- Keep the cable entry pointing downward to reduce water ingress risk
- Aim the flood beam at the immediate work area close to the machine and use a spot lamp separately for distant visibility
- Clean the PC lens with water and a soft cloth only—solvents will 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 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, with IP67 sealing and ECE R10 approval for electromagnetic compatibility.
