150W 12 000LM 6000K
The SLL-9151 is a 9 inch 150W LED off-road driving light designed for vehicles operating in extreme conditions where visibility and reliability are critical. The die-cast aluminium housing with UV-resistant powder coating and polycarbonate lens resists corrosion, impact and high temperatures, while IP68 sealing ensures operation in rain, fog and dust. R112 certification confirms compliance with vehicle lighting standards for road use.
- IP68 sealing and a die-cast aluminium housing allow continuous operation in rain, fog, dust and vibration
- R112 certification ensures the light meets vehicle lighting standards for road use
- 9 to 32V DC operation supports both 12V and 24V systems without voltage conversion
- Overvoltage and overheat protection prevent damage from electrical surges or thermal overload
- Lifespan exceeds 50,000 hours, reducing replacement frequency on high-mileage vehicles
Where This Lamp Is Used
- Front-mounted lighting on off-road trucks and 4x4 vehicles navigating unpaved trails at night
- Auxiliary lighting on construction and mining vehicles operating in low-light or dusty environments
- Fleet vehicles used in remote areas where road lighting is absent and visibility is limited
- Emergency response vehicles requiring reliable long-range illumination during night operations
- Heavy machinery used in logging or agriculture that operates beyond daylight hours
Who It Is For
- Distributors of off-road vehicle lighting needing a certified, high-output driving light
- 4x4 accessory brands building a private label range with proven performance in extreme conditions
- Fleet operators upgrading halogen driving lights that fail under vibration and heat
- Machinery OEMs integrating a reliable, certified light into new vehicle builds
- Equipment dealers fitting driving lights on machines used on public roads requiring R112 approval
Problems It Solves
- Halogen driving lights burn out quickly under vibration and draw excessive current from the vehicle electrical system
- Cheap LED lights with poor heat dissipation fail within months due to thermal stress
- Lights without R112 certification may be rejected during vehicle inspection on public roads
- Inadequate sealing allows water ingress during washing or in heavy rain, leading to fogging or short circuits
- Narrow beam lights leave the road edge and distant obstacles in shadow, increasing collision risk
Technical Features
- Nine CREE 5W LEDs with a raw output of 15,000 lumens and 12,000 effective lumens
- Die-cast aluminium housing with durable UV-resistant polyester powder coating
- Anti-impact polycarbonate lens with scratch-resistant surface
- DT plug-and-play wiring kit for quick installation
- Overvoltage and overheat protection circuits built into the driver
- Operating voltage range of 9 to 32V DC for compatibility with 12V and 24V systems
- Operating temperature range of -40 to +85 degrees Celsius
- IP68 waterproof and dustproof rating with sealed cable entry
- Lifespan rated at more than 50,000 hours

How It Compares With the Alternatives
| 6 inch LED driving light | Larger 9 inch body allows more LEDs and better heat dissipation, improving longevity and output |
|---|---|
| Flood beam version of the same lamp | Spot beam reaches further ahead and illuminates distant obstacles, while flood covers a wider area but with less reach |
| LED light without R112 certification | This model is approved for road use, avoiding rejection during vehicle inspection or compliance checks |
How to Fit and Use It
- Connect the DT plug to the vehicle’s fused 15A feed and ensure the cable entry points downward
- Leave a drip loop in the wiring to prevent water from entering the gland during rain or washing
- Aim the spot beam at the road ahead, not at the vehicle’s front bumper, to avoid glare for oncoming drivers
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that may damage the scratch-resistant 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 road going machines
