SUNLITEC 9D SINGLE ROW SPOTLIGHT AUTO LED LIGHT BAR SLL-9D Series
The SLL-9D Series is a single row spotlight LED light bar designed for vehicles and machinery that operate in low visibility conditions, including off-road, mining, and construction environments. Eight sizes from 8.5 inch to 53.4 inch offer scalable illumination for different vehicle widths and mounting constraints. Each model uses 5W CREE LEDs to deliver a focused beam with 3000 to 24000 effective lumens, ensuring visibility at distance without compromising on durability. The die-cast aluminium housing and IP69K sealing allow operation in high-pressure wash environments, while the 9-32V DC input range supports both 12V and 24V systems across fleets.
- Single row spotlight beam pattern delivers focused light up to 100 meters with consistent intensity
- IP69K waterproof rating allows operation after high-pressure water washes and in dusty or wet conditions
- 9-32V DC input range supports both 12V and 24V vehicle electrical systems, reducing SKU count
- 5W CREE LEDs provide 3000 to 24000 effective lumens across eight sizes for scalable lighting
- Die-cast aluminium housing with side mount bracket resists deformation under vibration and impact
Where This Lamp Is Used
- Front mounting on off-road vehicles and 4x4s for long-distance visibility during night driving
- Side mounting on excavators and cranes to illuminate work zones during night shifts
- Front lighting on tipper trucks and dump bodies where a narrow beam cuts through fog and dust
- Auxiliary lighting on mining machinery exposed to high vibration and frequent washdowns
- Fleet lighting on service vehicles and utility trucks where consistent beam pattern matters
Who It Is For
- Distributors sourcing LED light bars for resale across multiple vehicle types and voltages
- Machinery OEMs integrating a consistent lighting solution into production line builds
- Fleet operators replacing halogen or lower-lumen LED bars with longer-life, higher-output alternatives
- 4x4 accessory brands developing private label light bar ranges with proven performance
- Equipment dealers fitting lighting on machines used in harsh environments like mining and agriculture
Problems It Solves
- Halogen or low-lumen LED bars fail to provide visibility beyond 30 meters in dark or dusty conditions
- Multiple part numbers needed for 12V and 24V systems increase inventory complexity and ordering errors
- Non-uniform beam patterns from multi-row bars create uneven light distribution and glare
- Mild steel brackets or plastic housings degrade under vibration and exposure to salt or chemicals
Technical Features
- Single row of 5W CREE LEDs with a real power draw of 30W to 240W across eight sizes
- Spot beam pattern with effective lumen output from 3000 to 24000 lm depending on size
- Semi-gloss black powder coating on the full housing and bracket for corrosion resistance
- 9-32V DC input range supports both 12V and 24V electrical systems without voltage regulation
- Operating temperature range from -40 to +85 degrees Celsius for use in extreme climates
- IP69K sealing protects against high-pressure water jets, dust, and immersion in water
- 50,000 hour rated lifetime under continuous operation, measured from first use

How It Compares With the Alternatives
| Multi-row LED light bar | Single row design reduces weight and cost while maintaining a focused beam with less glare |
|---|---|
| 12V-only LED bar | 9-32V DC input range supports both 12V and 24V systems, reducing the need for separate SKUs |
| Halogen light bar of similar output | Draws less than half the current and lasts 10 times longer under continuous use |
| Plastic housing light bar | Die-cast aluminium housing resists deformation under vibration and high heat |
