Hot Selling RC Style 2D 3D 5D 5W CREE Single Row Light Bar SLL-14 Series
The SLL-14 Series is a slim straight or curved LED light bar designed for off-road vehicles, cranes, and engineering vehicles that need reliable, long-range lighting in harsh conditions. Six to fifty 5W CREE LEDs deliver 2580 to 21500 lumens across spot, flood, or combo beam patterns, with a 3D or 5D lens option for improved light distribution. The light bar operates on 9-32V DC, making it compatible with both 12V and 24V vehicle systems.
- 6 to 50 5W CREE LEDs provide 2580 to 21500 lumens with a choice of spot, flood, or combo beam patterns
- 3D or 5D lens option improves light spread and reduces hot spots compared to flat lenses
- Die-cast aluminium housing with semi-gloss black powder coating resists impact and heat
- 9-32V DC input allows the same part number to be used on 12V and 24V vehicles, reducing SKU count
Where This Lamp Is Used
- Front and side mounting on off-road vehicles and 4x4s used in mining and construction
- Rear and side lighting on cranes and excavators operating in low-light or dusty environments
- Auxiliary lighting on engineering vehicles and service trucks where vibration damages standard lamps
- Fleet vehicles used in remote areas where long bulb life reduces maintenance downtime
- Mounting on forklifts and industrial machinery where consistent light output is needed during night shifts
Who It Is For
- Distributors of vehicle lighting needing a consistent part number across 12V and 24V systems
- Machinery OEMs fitting light bars on production line machines and requiring repeatable mounting patterns
- Fleet operators replacing halogen or older LED bars that fail under vibration or moisture
- 4x4 accessory brands building a private label range with multiple beam and lens options
- Equipment dealers sourcing light bars for resale with mixed models in one order
Problems It Solves
- Halogen or low-output LED bars fail quickly under vibration and do not provide enough light for safe operation
- Flat lenses create hot spots and leave edges of the work area in shadow, reducing visibility
- Mild steel brackets rust within weeks on machines washed daily with water or cleaning agents
- Incompatible voltage ranges require separate SKUs for 12V and 24V fleets, increasing inventory complexity
- Poor sealing allows water and dust to enter, causing fogging or electrical failure after a few wash cycles
Technical Features
- Slim straight or curved design with a 7.3 to 50.8 inch length and 5W CREE LEDs
- Beam patterns available as spot, flood, or combo to match the vehicle’s lighting needs
- 3D or 5D lens option for improved light distribution and reduced glare
- Die-cast aluminium housing with semi-gloss black powder coating for heat dissipation and durability
- Anti-scratch UV resistant PC lens over the LED array to resist weathering and abrasion
- Sealed cable entry gland with drip loop design to prevent water ingress during washing
- Operating voltage range of 9-32V DC, compatible with 12V and 24V vehicle systems
- Rated for more than 50000 hours of continuous operation, reducing replacement frequency

How It Compares With the Alternatives
| Standard flat lens light bar | 3D or 5D lens spreads light more evenly and reduces glare on the road |
|---|---|
| Round or bulky light bar | Slim profile fits under vehicle bumpers and guards where space is limited |
| Lower lumen output bar | Higher lumen count allows visibility at longer distances without increasing power draw |
| Halogen light bar | Draws less current and lasts over 50000 hours compared to halogen’s few hundred hours |
How to Fit and Use It
- Mount using base or end brackets on a flat or slightly curved surface, ensuring the bracket width matches the machine’s mounting point
- Wire through a fused feed sized for the maximum current draw of the selected model
- Keep the cable entry gland pointing downward and leave a drip loop to prevent water from entering
- Select the beam pattern and lens type (3D/5D) based on the vehicle’s lighting needs and road conditions
- Clean the PC lens with water and a soft cloth only—avoid solvents that may damage 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.
