9 Inch 72W 4800 LM
The SLL-9721 is a 9 inch high beam LED driving light built for off-road vehicles that operate in dark, rugged terrain and must withstand vibration, dust, and water exposure. Twelve 5W Osram LEDs deliver 4800 effective lumens in a high beam pattern, providing clear visibility across uneven ground and improving safety on unlit trails. The die-cast aluminium housing is sealed to IP68 and carries R10, R112, and R87 approvals, which are required for vehicles used on public roads in Europe and other regulated markets.
- 4800 effective lumens in a high beam pattern cover the road ahead without creating a hot spot
- IP68 sealing and a durable polycarbonate lens resist water, dust, and shock during off-road use
- R10, R112, and R87 approvals ensure compliance with vehicle lighting regulations in Europe and other regions
- 12×5W Osram LEDs provide stable, bright light with overvoltage and overheat protection
- 9 to 32V DC operation allows use on both 12V and 24V off-road vehicles without voltage conversion
Where This Lamp Is Used
- Front driving lights on off-road 4x4s and ATVs navigating dark forest trails
- Auxiliary lighting on utility vehicles and service trucks operating in remote areas
- Rear-mounted driving lights on mining support vehicles where vibration and dust are constant
- Fleet vehicles used on public roads that must pass electrical and lighting inspections
- Night operations on construction sites where visibility must extend beyond the immediate vehicle
Who It Is For
- Distributors of off-road vehicle lighting needing a single part number for 12V and 24V systems
- 4x4 accessory brands building a private label driving light range with regulatory compliance
- Fleet operators replacing halogen driving lights that fail under vibration and heat
- Machinery OEMs integrating driving lights into production line builds with consistent mounting
- Equipment dealers fitting lights on machines used on public roads and requiring certification
Problems It Solves
- Halogen driving lights burn out quickly under vibration and draw more current than LED alternatives
- Cheap sealed lights fail after a few wash cycles due to poor cable gland sealing and lens fogging
- Uncertified lights are rejected during road inspections in Europe and other regulated markets
- Narrow beam lights create a bright spot but leave the edges of the road or trail in shadow
- Low voltage tolerance in some LEDs causes flickering or failure on 12V systems under load
Technical Features
- Twelve 5W Osram LEDs with a real power draw of 69W and 72W maximum rating
- Semi-gloss black powder coating over the full housing and bracket
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- EMC protected wiring and an operating window of -40 to +85 degrees Celsius
- Overvoltage and overheat protection built into the driver circuit

Quality Control on This Model
- Photometric output verified in an integrating sphere
- Sealing verified against the IP68 rating before shipment
- Vibration testing on a vibration test machine to reproduce machine mounted service
- Salt spray corrosion testing on housing coating and stainless bracket
- High and low temperature alternating humidity testing across the -40 to +85 degrees Celsius window
Customisation Options
- Deutsch DT connector instead of the standard 40cm bare wire lead
- Spot beam optics in place of the high beam pattern
- Private label logo on the housing and printed carton
- Alternative cable length for a specific machine harness
- Mixed cartons combining this lamp with other SUNLITEC models for trial orders
How It Compares With the Alternatives
| Round 9 inch driving light | The square body puts more LED area behind the same mounting footprint but needs a flat surface for the bottom bracket |
|---|---|
| Spot beam version of the same lamp | High beam covers the road ahead evenly while spot reaches further ahead but leaves the machine edges dark |
| Larger 12 inch driving light | Lower output but fits guard rails and cab pillars where a 12 inch body will not clear |
How to Fit and Use It
- Leave a drip loop in the 40cm lead so water runs away from the gland rather than into it
- Aim the high beam at the road ahead and use a spot lamp separately for distant obstacles
- Clean the PC lens with water and a soft cloth only, since solvents will haze 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 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 CE, RoHS, EMC, ECE R10, R112, R87 and IP68 compliant, which together meet requirements for public road use in Europe and other regulated markets.
