4 Inch 60W Offroad Side Shooter LED Cube Light EMC CISPR 25 CLASS 4
The SLL-4060 is a 4 inch cube LED side shooter light designed for off-road vehicles and heavy machinery that operate in extreme conditions. Twelve 5W CREE LEDs deliver 4200 effective lumens across a 120 degree flood beam, providing even illumination across the side work zone without creating a hot spot. The die-cast aluminium housing with IP68 sealing and overvoltage and overheat protection ensures reliable operation in dust, rain, and vibration. EMC CISPR 25 Class 4 compliance prevents electrical interference with vehicle electronics, which is critical on modern machines with sensitive control systems.
- 120 degree flood beam spreads 4200 effective lumens evenly across the side work area instead of a narrow hotspot
- EMC CISPR 25 Class 4 compliance ensures no interference with vehicle ECUs, sensors, or radio systems
- IP68 sealing and a durable polycarbonate lens keep water and dust out during pressure washing and off-road use
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged high ambient temperatures
- 9 to 32V DC operation allows use on both 12V and 24V systems without changing part numbers
Where This Lamp Is Used
- Side lighting on off-road vehicles and 4x4s used in mining, forestry, or construction during night operations
- Auxiliary lighting on excavators and cranes where side visibility is needed for boom and bucket control
- Fleet vehicles with sensitive electronics that cannot tolerate electromagnetic noise from unshielded lights
- Side-mounted work lights on utility trucks and service vehicles operating in wet or dusty environments
- Lighting on machinery where a narrow beam would leave the operator’s side edge in shadow
Who It Is For
- Distributors of off-road vehicle lighting needing a single part number for 12V and 24V fleets
- Machinery OEMs integrating lights on production lines with strict EMC requirements
- Fleet operators replacing halogen side lights that fail due to electrical noise or heat
- 4x4 accessory brands building a private label range with proven EMC compliance
- Equipment dealers fitting lights on machines used in mining or agriculture with high vibration
Problems It Solves
- Unshielded LED lights cause electromagnetic interference that disrupts vehicle sensors and control units
- Narrow beam lights leave the side of the machine in shadow, increasing risk during side work
- Cheap lights fail under vibration or in wet conditions due to poor sealing and low-grade materials
- Halogen side lights draw more current, overheat, and have short lifespans on continuous duty
- Lights not rated for 9–32V DC require different part numbers for 12V and 24V systems, increasing inventory
Technical Features
- Twelve 5W CREE LEDs with a real power draw of 60W and 60W maximum rating
- 120 degree flood beam pattern with 4200 effective lumens output
- Semi-gloss black durable UV polyester powder coating over the full housing
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- EMC protected wiring and an operating window of -40 to +85 degrees Celsius
- Overvoltage and overheat protection circuits built into the driver module

How It Compares With the Alternatives
| Standard LED side light without EMC shielding | This model meets CISPR 25 Class 4, so it will not interfere with vehicle electronics, while unshielded lights can cause sensor errors or ECU resets |
|---|---|
| Narrow spot beam version of the same lamp | The 120 degree flood beam covers the side work zone evenly, while a spot beam leaves the machine edge in shadow |
| Round 4 inch work lamp | The cube shape fits flush against flat surfaces on vehicle sides and cab pillars where a round body would not clear |
| Larger 6 inch work lamp | Lower output but fits tight mounting spaces on side panels where a 6 inch body would interfere with other components |
How to Fit and Use It
- Mount on a flat surface using the bottom bracket and check the 42mm 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 side work zone 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 it approved for use on vehicles with sensitive electronics
Yes. The lamp is EMC CISPR 25 Class 4 compliant, which means it will not cause electromagnetic interference with vehicle ECUs, sensors, or radio systems.
