Best LED Tractor Work Lights
The SLL-0602-40 is a 4 inch rectangular LED work light designed for tractors and other heavy machinery that operate in low-light conditions, dusty environments, and under vibration. It delivers 1620 effective lumens from 40 x 1W Osram LEDs, providing even flood illumination across the work zone instead of a narrow hotspot. The die-cast aluminium housing with UV-resistant polyester coating and IP68 sealing ensures durability in outdoor and wash-down environments. The 9–32V DC operating range supports both 12V and 24V systems, reducing SKU complexity for fleet operators and OEMs.
- 1620 effective lumens from 40 x 1W Osram LEDs provide broad, even flood lighting across the work area
- IP68 sealing and a die-cast aluminium housing resist water, dust, and vibration on machines exposed to harsh conditions
- 9–32V DC input allows one part number to serve both 12V and 24V vehicle systems, simplifying inventory
- Overvoltage and overheat protection prevent failure during electrical surges or prolonged operation
- UV-resistant polycarbonate lens maintains clarity over time without yellowing or cracking
Where This Lamp Is Used
- Front and side work lighting on tractors and harvesters operating during early morning or late evening shifts
- Cab roof and loader bucket lighting on agricultural machinery used in dusty or wet field conditions
- Auxiliary lighting on utility and service trucks where vibration and exposure to rain are common
- Fleet maintenance lighting on forklifts and engineering vehicles that require consistent visibility after wash cycles
- Nighttime loading and unloading operations on tipper trucks and dump bodies where a wide beam prevents dark edges
Who It Is For
- Distributors of 12V and 24V vehicle lighting needing a single part number for both voltage systems
- Machinery OEMs integrating work lights into production lines with consistent mounting and wiring
- Fleet operators replacing halogen lights that fail under vibration and draw excessive current
- Agricultural accessory brands building a private label work light range with proven durability
- Equipment dealers fitting lights on machines that must pass inspection in humid or dusty environments
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 or lens degradation
- Narrow beam lights leave the edges of the machine dark, increasing risk during close proximity tasks
- Lights with narrow voltage ranges require multiple SKUs for 12V and 24V fleets, increasing stock complexity
- Unprotected LED drivers fail during voltage spikes common in industrial vehicle electrical systems
Technical Features
- 40 x 1W Osram LEDs with a real power draw of 40W and a maximum rating of 40W
- Flood beam pattern with 1620 effective lumens and 1800 raw lumens
- Semi-gloss black UV-resistant polyester powder coating over the full housing
- Bare wire lead of 40cm as standard with overvoltage and overheat protection built into the driver
- Operating range of 9–32V DC, suitable for 12V and 24V vehicle systems
- Rated for -40 to +85 degrees Celsius, suitable for extreme cold and hot environments
- IP68 sealing with a sealed cable entry gland to prevent water and dust ingress

Powder coating in semi-gloss black with UV resistance
LED board assembly with 40 x 1W Osram emitters
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 machine-mounted service
- Salt spray corrosion testing on housing coating and internal components
- High and low temperature alternating humidity testing across the -40 to +85 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 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 rectangular body fits flush on flat surfaces and provides more LED area than a round lamp of the same footprint |
|---|---|
| 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 tight spaces like cab pillars and guard rails where a 6 inch body will 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 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 degrade 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 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 IP68 sealing, which supports use on machines used on public roads.
