4 Inch 12V 24V Factory Supply LED Auxiliary Light Tractor Light 30W LED Work Light
Six 5W Osram LEDs deliver 2700 effective lumens at 30W real power, providing consistent illumination across the work zone instead of a narrow hot spot. The die-cast aluminium housing is sealed to IP68 and rated for -40 to +105 degrees Celsius, ensuring reliable operation in extreme temperatures. The light is compatible with 9-32V DC systems, so the same part number works on both 12V and 24V machines, reducing SKU complexity for fleet operators and OEMs.
- Six Osram 5W LEDs deliver 2700 effective lumens with a real 30W power draw, improving visibility across the work area
- IP68 sealing and a 316 stainless steel bracket resist water, dust, and corrosion in daily washdown environments
- Operating range of 9-32V DC allows one part number to serve both 12V and 24V vehicle systems
- Rated for more than 50,000 hours, reducing replacement frequency on machines with long operating cycles
- 316 stainless steel mounting bracket maintains strength and resists rust on machines exposed to salt or chemicals
Where This Lamp Is Used
- Front and side work lighting on tractors and forklifts operating in low-light fields or warehouses
- Auxiliary lighting on excavators and engineering vehicles where vibration damages standard sealed lamps
- Cab roof and under-chassis lighting on utility trucks and service vehicles used at night
- Loading and unloading zone illumination on tipper trucks and container handlers
- Nighttime operation lighting on mining support vehicles and mobile cranes in remote areas
Who It Is For
- Distributors of vehicle lighting who need a single part number for 12V and 24V fleets
- Machinery OEMs fitting work lights on production lines and requiring repeatable mounting patterns
- Fleet operators replacing halogen lamps that fail after a few hundred hours of use
- 4x4 and agricultural accessory brands building a private label work light range
- Equipment dealers sourcing reliable auxiliary lighting for resale on heavy machinery
Problems It Solves
- Halogen work lamps fail early under vibration and draw significantly more current than LED alternatives
- Cheap sealed lamps allow water ingress through the cable entry and fog up after a few wash cycles
- Narrow beam lamps light a small bright patch and leave the working edge of the machine in shadow
- Painted mild steel brackets rust within a season on machines washed daily with water or chemicals
- Lack of voltage tolerance forces separate SKUs for 12V and 24V systems, increasing inventory complexity
Technical Features
- Six Osram 5W LEDs with a real power draw of 30W and a maximum rating of 30W
- Flood or spot beam pattern available as an option, with a 2700 lumen output
- Semi-gloss black powder coating over the full housing and bracket
- DT connector as standard, with bare wire available on request
- Operating voltage range of 9-32V DC, compatible with 12V and 24V systems
- Rated for -40 to +105 degrees Celsius, suitable for extreme cold and high-heat environments
- Sealed cable entry gland with silicone gasket to maintain IP68 rating under pressure

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 +105 degrees Celsius window
Customisation Options
- DT connector instead of the standard 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
- Leave a drip loop in the 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 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 there a warranty
Yes. A 1-year warranty is offered on all products.
