Offroad CREE LED Light Bar EMC CISPR 25 CLASS 4
The SLL-88X is a 10W CREE LED light bar designed for off-road vehicles and heavy machinery that operate in extreme conditions. It delivers consistent illumination through a spot, flood, or combo beam pattern with a 6000K colour temperature, ensuring visibility in dust, rain, and high vibration environments. The die-cast aluminium housing and IP68 sealing prevent water and dust ingress during prolonged exposure. EMC protection to CISPR 25 Class 4 ensures the light bar does not interfere with vehicle electronics, which is critical for modern machines with advanced control systems.
- CISPR 25 Class 4 EMC protection prevents interference with vehicle electronics on modern off-road machines
- 10W CREE LED delivers high brightness with low power draw and long lifespan of more than 50000 hours
- IP68 sealing and a durable UV polyester powder coating resist water, dust, and UV degradation in harsh outdoor environments
- Operates reliably across 9 to 32V DC, covering both 12V and 24V systems without voltage regulation
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged high-temperature operation
Where This Lamp Is Used
- Front mounting on off-road vehicles and 4x4s for high-speed night driving on unpaved trails
- Side and rear mounting on excavators and cranes where consistent beam coverage is needed in dusty or wet conditions
- Auxiliary lighting on engineering vehicles and mining machinery where electrical noise from other systems can disrupt sensors
- Fleet vehicles operating in remote areas with unstable power supplies and frequent voltage spikes
- Mounting on utility and service trucks where the light bar must survive daily exposure to rain, salt, and vibration
Who It Is For
- Distributors of off-road vehicle lighting needing a single model with multiple beam options and EMC compliance
- Machinery OEMs integrating lighting into new builds where electronic compatibility is a design requirement
- Fleet operators replacing older LED bars that fail due to electrical noise or heat buildup
- 4x4 accessory brands building a private label range with proven EMC and environmental performance
- Equipment dealers fitting lights on machines used in mining, construction, and agriculture with high vibration
Problems It Solves
- Cheap LED light bars without EMC protection can cause malfunctions in vehicle control modules or sensor systems
- LEDs with short lifespans fail after a few hundred hours in continuous use, increasing maintenance costs
- Light bars with inadequate sealing let water in during pressure washing or heavy rain, leading to internal corrosion
- Voltage fluctuations in 12V and 24V systems can damage unregulated LED drivers, especially in older vehicles
- Standard powder coatings degrade under UV exposure, causing fading and reduced protection over time
Technical Features
- 10W CREE LED with a 6000K colour temperature for clear, daylight-like visibility

- Durable polycarbonate lens resistant to impact and UV degradation
- Operating voltage range of 9 to 32V DC, compatible with 12V and 24V systems
- Overvoltage and overheat protection circuits to extend component life
- IP68 sealing ensures full protection against water and dust ingress
- EMC protection to CISPR 25 Class 4 standard, preventing electromagnetic interference
- Lifespan rated at more than 50000 hours under normal operating conditions
- Operating temperature range from -40 to +85 degrees Celsius, suitable for extreme climates

How It Compares With the Alternatives
| Standard LED light bar without EMC protection | This model meets CISPR 25 Class 4, preventing interference with vehicle electronics, while others may cause sensor or control system errors |
|---|---|
| LED bar using generic LEDs | CREE 10W LEDs offer higher efficiency and longer lifespan than generic equivalents under continuous duty |
| Light bar with plastic housing | Die-cast aluminium housing provides better heat dissipation and mechanical strength in high-vibration environments |
How to Fit and Use It
- Mount the light bar on a flat, stable surface using the provided bracket or bolts, ensuring no stress on the housing
- Connect the cable to a fused 10A feed sized for the 10W input, and route the cable away from moving parts
- Keep the cable entry point facing downward to prevent water from entering the gland
- Select the beam pattern (spot, flood, or combo) based on the intended use: spot for long distance, flood for wide coverage, combo for mixed needs
- Avoid exposing the lens to solvents or abrasive cleaners; clean with water and a soft cloth only
Questions About This Model
