9 Inch 225W High Power LED Driving Light Spot
The SLL-9225 is a 9 inch high power LED driving light spot designed for vehicles that operate in low visibility conditions and extreme environments. The die-cast aluminium housing with UV resistant polyester powder coating and IP68 sealing ensures long-term durability under dust, water, and vibration. The light operates across a 9–32V DC range and includes overvoltage and overheat protection for stable performance in variable electrical systems.
- 45 x 5W CREE LEDs provide high output with a real power draw of 225W and a 50,000 hour lifespan
- IP68 sealing and a die-cast aluminium housing resist water, dust, and vibration in harsh operating conditions
- Overvoltage and overheat protection prevent damage during electrical surges or prolonged high-temperature use
- 9–32V DC operation supports both 12V and 24V systems, reducing the need for multiple SKUs
- Durable UV resistant polyester powder coating maintains appearance and protection over time
Where This Lamp Is Used
- Front lighting on off-road vehicles and 4x4s navigating remote trails at night
- Primary illumination on excavators and mining machinery operating in deep pits or tunnels
- Emergency vehicle lighting where long-range visibility is critical during rescue operations
- Truck and bus headlight replacement in regions with poor road lighting and frequent fog
- Fleet vehicles operating in desert or coastal environments where dust, salt, and heat degrade standard lights
Who It Is For
- Distributors of off-road and heavy machinery lighting needing a high-output spot beam for resale
- Machinery OEMs integrating a consistent, high-lumen driving light into production line builds
- Fleet operators replacing halogen or low-lumen LED lights that fail under sustained use
- 4x4 accessory brands building a private label driving light range with proven long-range performance
- Equipment dealers fitting lights on machines used in mining, construction, and emergency services
Problems It Solves
- Halogen driving lights burn out quickly under vibration and draw excessive current from the alternator
- Non-sealed lights allow water and dust ingress, leading to internal corrosion and early failure
- Lights without overvoltage protection are damaged by electrical spikes in 24V truck systems
- Painted metal housings degrade under UV exposure and salt spray, reducing lifespan and appearance
- Narrow beam lights with poor heat dissipation overheat and reduce LED output over time
Technical Features
- Forty-five 5W CREE LEDs with a total power draw of 225W and 18,000 lumens output
- Die-cast aluminium housing with durable UV resistant polyester powder coating
- Anti-UV, impact-resistant polycarbonate lens with high light transmission
- Overvoltage protection and overheat protection circuits for electrical and thermal safety
- 9–32V DC input range supports both 12V and 24V vehicle systems without voltage regulation
- Operating temperature range of -40 to +85 degrees Celsius for use in extreme climates
- IP68 sealing rating prevents ingress of dust and water, including immersion
- Bare wire lead of 1 meter as standard with connector options available on request
- Rounded edge design reduces wind resistance and improves aerodynamic performance

- Private label logo on the housing and printed carton
- Custom cable length to match a specific vehicle harness
- Mixed cartons combining this light with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| 10 degree spot beam with lower output | 18,000 lumens vs. 8,000–10,000 lumens from similar-sized lights |
|---|---|
| Round 9 inch light | Same beam pattern but square housing allows easier mounting on flat surfaces |
| Lower voltage range light | 9–32V DC vs. 12–24V DC, so compatible with 24V mining and truck systems |
How to Fit and Use It
- Mount on a flat surface using the provided bracket pattern and ensure the housing is not obstructed by guard rails or bodywork
- Leave a drip loop in the 1 meter lead to prevent water from entering the gland
- Aim the 10 degree spot beam at the farthest point of the intended path, not directly at the vehicle’s front
- Clean the polycarbonate lens with water and a soft cloth only—avoid solvents that degrade UV 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
