Offroad Utility CREE LED Light Bar Version 2
The SLL-90X is a 3W CREE LED light bar designed for off-road utility vehicles and heavy machinery that operate in extreme conditions. It delivers consistent illumination across rough terrain, dust, rain, and vibration, with a 50,000 hour lifespan and IP68 sealing to prevent water and dust ingress during pressure washing or prolonged exposure. The die-cast aluminium housing and durable polycarbonate lens ensure long-term reliability in demanding environments.
- 3W CREE LEDs provide bright, even light output with a 6000K colour temperature for clear visibility in low-light conditions
- IP68 waterproof and dustproof rating ensures operation in heavy rain, mud, and high-pressure wash environments
- 9 to 32V DC operating range supports both 12V and 24V vehicle systems without requiring different part numbers
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged high-temperature operation
- 50,000 hour lifespan reduces maintenance frequency and replacement costs on machines used in remote or hard-to-reach locations
Where This Lamp Is Used
- Front or side mounting on off-road utility vehicles used in mining, forestry, or construction
- Auxiliary lighting on excavators and cranes operating at night in remote sites
- Mounting on tipper trucks and engineering vehicles where vibration and dust degrade standard lighting
- Fleet vehicles used in agriculture or utility services that require reliable lighting after dark
- Lighting for service and maintenance vehicles operating in harsh weather conditions
Who It Is For
- Distributors sourcing LED light bars for off-road and industrial vehicle markets
- Machinery OEMs integrating lighting into new machine builds with consistent electrical and mechanical specs
- Fleet operators replacing halogen or low-lifespan LED bars that fail under vibration or moisture
- 4x4 accessory brands developing private label lighting solutions for off-road vehicle upgrades
- Equipment dealers fitting lighting on machines before resale to end users in remote regions
Problems It Solves
- Halogen or low-quality LED bars fail quickly under vibration and moisture, leading to frequent replacements
- Light bars with inadequate sealing allow water and dust into the housing, causing internal corrosion and short circuits
- Inconsistent voltage tolerance in some light bars causes premature failure when connected to 12V or 24V systems
- Narrow or uneven beam patterns leave parts of the work area in shadow, increasing accident risk
- Lack of overheat or overvoltage protection leads to sudden failure during high-load or high-temperature operation
Technical Features
- Three 3W CREE LEDs with a real power draw of 9W and a maximum rating of 10W
- Beam options available: spot, flood, or combo beam to suit different operational needs
- Die-cast aluminium housing with semi-gloss black UV polyester powder coating
- Durable anti-scratch polycarbonate lens with UV protection
- Overvoltage protection circuit to prevent damage from voltage spikes
- Overheat protection to shut down the unit if internal temperature exceeds safe limits
- Operating voltage range of 9 to 32V DC, compatible with 12V and 24V vehicle systems
- Operating temperature range of -40 to +85 degrees Celsius
- IP68 sealing for full protection against water and dust ingress
- Bare wire lead of 40cm standard, with connector options available on request

Lens bonding with silicone sealant and gasket installation
Quality Control on This Model
- Photometric output verified in an integrating sphere to confirm beam pattern and lumen output
- IP68 sealing tested under water immersion and dust exposure conditions
- Vibration testing on a vibration test machine to simulate real machine mounting conditions
- Salt spray corrosion testing on the powder-coated housing and bracket
- High and low temperature alternating humidity testing across the -40 to +85 degrees Celsius range
Customisation Options
- Spot, flood, or combo beam optics based on customer requirement
- Deutsch connector or other terminal types instead of standard bare wire lead
- Private label logo printed on the housing and carton
- Alternative cable length to match specific machine harnesses
- Mixed cartons combining this light bar with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Standard 3W LED light bar with plastic housing | Die-cast aluminium housing resists deformation under impact and heat, while plastic warps or cracks over time |
|---|---|
| Light bar without overheat protection | Overheat protection prevents sudden failure during prolonged use in high ambient temperatures |
| Light bar with non-CREE LEDs | CREE LEDs offer higher lumen output and longer lifespan under continuous duty cycles |
How to Fit and Use It
- Leave a drip loop in the wire to prevent water from running into the cable gland
- Select the appropriate beam pattern (spot, flood, or combo) based on the operational need—spot for distance, flood for near area, combo for both
- Clean the polycarbonate lens with water and a soft cloth only; avoid solvents that may degrade 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 light bar 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 public roads
The light bar is CE and RoHS compliant, with IP68 sealing and ECE R10 approval for electromagnetic compatibility, which supports use on road-going machines.
