9 Inch 120W Combo Beam Round LED Driving Light SLL-9120-120W
The SLL-9120-120W is a 9 inch round LED driving light designed for off-road and heavy machinery that operates in extreme conditions. Twelve 10W CREE LEDs deliver 8400 lumens across a combo beam pattern, providing both long-range spot and wide-area flood coverage. The die-cast aluminium housing with IP69K sealing resists water, dust, and high-pressure washes, making it suitable for trucks, excavators, and mining vehicles that face harsh environments.
- 120W total power with 8400 lumens from 12 CREE 10W LEDs for high visibility in low light
- Combo beam pattern delivers both spot for distance and flood for near-side coverage
- IP69K sealing protects against high-pressure water jets, dust, and vibration
- Die-cast aluminium housing resists impact and dissipates heat effectively
- 9-32V DC operating range supports both 12V and 24V systems without changing part number
Where This Lamp Is Used
- Front lighting on off-road trucks and 4x4s operating in mountainous or desert terrain
- Primary lighting on excavators and engineering vehicles working at night or in tunnels
- Auxiliary lighting on mining machinery exposed to dust, mud, and high-pressure cleaning
- Fleet vehicles used in construction zones where lights must survive repeated washdowns
- Truck and bus headlights in regions with poor road lighting and frequent fog
Who It Is For
- Distributors sourcing high-output LED driving lights for resale in off-road and industrial markets
- Machinery OEMs integrating lighting into production line builds with consistent mounting
- Fleet operators replacing halogen or lower-lumen LED lights that fail under vibration
- 4x4 accessory brands developing a private label driving light line with high performance
- Equipment dealers fitting lights on machines that must pass inspection in wet or dusty environments
Problems It Solves
- Halogen driving lights burn out quickly under vibration and draw excessive current
- Low-lumen LED lights fail to provide adequate visibility in deep darkness or fog
- Sealed lights with poor IP ratings let water in during pressure washing or rain
- Single beam lights (spot or flood only) leave either the far distance or near edges unlit
- Non-impact-resistant housings crack or deform on machines that hit obstacles
Technical Features
- Twelve 10W CREE LEDs with a total power draw of 120W and 8400 lumens output
- Combo beam pattern with adjustable split between spot and flood for flexible use
- IP69K waterproof rating suitable for high-pressure washes and dust exposure
- 9-32V DC input range compatible with 12V and 24V vehicle electrical systems
- Bare wire lead of 40cm standard with Deutsch connector available on request
- Lifespan rated at more than 50,000 hours under continuous operation

How It Compares With the Alternatives
| Halogen driving light of similar output | Draws 10A at 12V against roughly triple that for halogen and survives vibration that destroys filament-based lights |
|---|---|
| Round 6 inch LED driving light | Higher output and wider beam coverage from the 9 inch body, but requires more mounting space |
| Spot beam version of the same lamp | Combo beam covers both distance and near-side areas, while spot only illuminates ahead |
| Lower power 60W LED driving light | Twice the lumens and IP69K sealing, but larger size and higher power draw |
How to Fit and Use It
- Wire through a fused feed sized for 10A at 12V or 5A at 24V and keep the cable entry pointing downward
- Leave a drip loop in the 40cm lead to prevent water from entering the gland
- Aim the combo beam to balance distance reach and side coverage based on the machine’s use case
- Clean the PC lens with water and a soft cloth only—avoid solvents that may damage the anti-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
The lamp is IP69K sealed and operates within 9-32V DC, but no specific road approval is listed beyond general compliance with CE and RoHS standards.
