40W 3.3 Inch Square CREE LED Cube Work Light for Offroad 12V/24V Truck Tractor SLL-13117
The SLL-13117 is a 3.3 inch square cube work light designed for off-road vehicles and heavy machinery that operate in harsh conditions. Four 3W CREE XML2 LEDs deliver a focused spot beam with 1040 effective lumens, providing clear visibility at distance on trucks, tractors, and excavators working at night or in low-light environments. The die-cast aluminium housing with half-gloss black powder coating and stainless steel bracket resists corrosion and vibration, while IP68 sealing ensures performance during pressure washing and exposure to dust and water.
- Spot beam pattern with 15 degree focus delivers 1040 effective lumens at distance, ideal for illuminating paths and obstacles ahead
- IP68 sealing prevents water ingress during pressure washing and prolonged exposure to rain or dust
- Stainless steel mounting bracket resists rust on machines washed with salt or chemical residue
- 10-30V DC operation allows the same part number to be used on both 12V and 24V vehicle systems
- Die-cast aluminium housing with half-gloss black coating resists heat and impact during heavy-duty use
Where This Lamp Is Used
- Front mounting on off-road trucks and tractors for night driving in remote areas
- Side and rear lighting on excavators and loaders during low-light construction shifts
- Auxiliary lighting on utility vehicles and service trucks operating in rural or unlit zones
- Cab roof or hood lighting on tractors used for night field operations
- Mounting on mining support vehicles where vibration and dust degrade standard lighting
Who It Is For
- Distributors of off-road vehicle lighting needing one SKU for 12V and 24V fleets
- Machinery OEMs integrating work lights into production line builds with consistent mounting patterns
- Fleet operators replacing halogen lights that fail under vibration and high current draw
- 4x4 accessory brands developing a private label cube light range with spot beam focus
- Equipment dealers fitting reliable lighting on machines used in agriculture, mining, and construction
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw excessive current from vehicle electrical systems
- Cheap sealed lights allow water entry through the cable gland and fog up after repeated wash cycles
- Non-IP68 rated lights fail when exposed to high-pressure washes on daily-maintained machinery
- Narrow beam lights with low lumen output leave the immediate work zone in shadow
- Painted mild steel brackets corrode within weeks on machines exposed to salt or cleaning agents
Technical Features
- Four 3W CREE XML2 LEDs with a total theoretical power draw of 12W and 40W maximum rating
- Spot beam pattern with a 15 degree focus angle and 1040 effective lumens
- Half-gloss black powder coating over the full housing and bracket
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- Operating temperature range of -40 to +50 degrees Celsius
- EMC protected wiring and sealed cable entry gland to prevent interference and water ingress

- Private label logo on the housing and printed carton
- Alternative 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 3.3 inch work lamp | The square body fits a flat mounting surface and provides a more stable base than round bodies with smaller contact area |
|---|---|
| Flood beam version of the same lamp | Spot beam reaches further ahead while flood covers a wider area but with lower intensity at distance |
| Larger 4 inch work lamp | Lower power draw and smaller footprint allow installation in tight spaces where a 4 inch body would not fit |
How to Fit and Use It
- Leave a drip loop in the 40cm lead to prevent water from running into the gland
- Aim the spot beam at the path ahead and use a flood lamp separately for near-area illumination
- 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
The lamp is CE and RoHS compliant and carries IP68 sealing, but does not list ECE R10 or other road approval.
