Offroad High Intensity CREE LED Light Bar Version 2
The SLL-82X is a high intensity LED light bar designed for off-road vehicles and heavy machinery that operate in extreme conditions. Built with 3W CREE LEDs and a die-cast aluminium housing, it delivers consistent illumination across rugged terrain, rain, dust, and vibration. The light bar operates on 9–32V DC, making it compatible with both 12V and 24V systems, and carries IP68 sealing to prevent water and dust ingress during pressure washing or exposure to mud and debris.
- 3W CREE LEDs provide high lumen output with stable performance under extreme temperature changes
- IP68 sealing ensures no water or dust enters the housing even during submersion or high-pressure cleaning
- 9–32V DC operation supports both 12V and 24V vehicle systems without requiring different part numbers
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged use in high ambient temperatures
- Durable UV polyester powder coating resists fading and chipping in direct sunlight and harsh environments
Where This Lamp Is Used
- Front lighting on off-road vehicles and 4x4s navigating muddy trails and rocky terrain
- Side and underside mounting on excavators and cranes working in wet or dusty construction zones
- Auxiliary lighting on mining trucks and engineering vehicles exposed to continuous vibration and dust
- Night operation on agricultural machinery where consistent beam patterns are needed across uneven fields
- Fleet vehicles used in remote areas where long service life and minimal maintenance are critical
Who It Is For
- Distributors of off-road lighting needing one model to cover both 12V and 24V vehicle fleets
- Machinery OEMs integrating lighting into production line builds with consistent mounting patterns
- Fleet operators replacing halogen or low-lifespan LED bars that fail under vibration or heat
- 4x4 accessory brands developing private label light bars with proven durability and certification
- Equipment dealers fitting lighting on machines used in mining, agriculture, and construction
Problems It Solves
- Halogen or low-grade LED bars fail quickly under vibration and heat, requiring frequent replacement
- Poorly sealed light bars allow water and dust to enter, causing internal corrosion and lens fogging
- Inconsistent voltage tolerance leads to premature failure when voltage spikes occur during engine start
- Narrow or uneven beam patterns leave blind spots in the work zone, increasing accident risk
- Painted or non-UV-resistant coatings fade and peel after months of sun exposure, reducing visual appeal and protection
Technical Features
- Three 3W CREE LEDs with a total real power draw of 9W and a maximum of 12W
- Beam patterns available as spot, flood, or combo to suit different operational needs
- Die-cast aluminium housing with a semi-gloss UV resistant polyester powder coating
- Polycarbonate lens with anti-reflective and scratch-resistant properties
- Overvoltage protection circuit prevents damage from voltage spikes above 32V
- Overheat protection shuts down the LEDs if internal temperature exceeds safe operating limits
- Operating temperature range of -40 to +85 degrees Celsius for use in arctic and desert environments
- 9–32V DC input allows use on 12V and 24V systems without changing part numbers
- IP68 sealing rated for continuous submersion and high-pressure washing
- End mounting and underside mounting bracket included for flexible installation on vehicles and machines

How It Compares With the Alternatives
| Standard 3W LED light bar with generic LEDs | CREE LEDs offer better lumen output and longer lifespan under thermal stress |
|---|---|
| Light bar without overvoltage protection | Built-in protection prevents damage from voltage spikes during engine start or alternator failure |
| Light bar with plastic housing | Die-cast aluminium housing handles heat better and resists impact and deformation |
| Light bar with standard paint finish | UV resistant polyester powder coating resists fading and chipping in direct sunlight |
How to Fit and Use It
- Mount the light bar using the end or underside bracket, ensuring the mounting surface is flat and secure
- Route the cable so the entry point faces downward to prevent water from entering the gland
- Select the beam pattern (spot, flood, or combo) based on the intended use—distance, area coverage, or both
- Avoid direct contact with the lens during installation to prevent scratches on the anti-reflective 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 light bar 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 light bar 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 machines used on public roads
The light bar is CE and RoHS compliant and carries IP68 sealing, but ECE R10 or similar road approval is not listed in the product facts.
