SUNLITEC 49 Series High Power Dual Row 240W Combo Beam 20 Inch Light Bar
The SLL-49-20"-COMBO is a 20 inch high power dual row LED light bar designed for off-road vehicles and heavy machinery that operate in dark, dusty, and wet conditions. Forty 6W Osram P8 LEDs deliver 7982 effective lumens across a combo beam pattern, providing both wide flood coverage and long-distance spot reach. The integrated design with no screw front frame improves waterproofing and heat dissipation, while the 9-36V DC compatibility ensures reliable operation across 12V and 24V vehicle systems.
- Dual row configuration with 40 Osram P8 LEDs delivers 7982 effective lumens for wide and long-range visibility
- No screw front frame design reduces risk of water ingress and condensation in high vibration environments
- Optimized reflector and thermal design improves light efficiency and maintains performance under prolonged use
- Slim low profile allows fitment in tight bumper and grill spaces on trucks, SUVs, and excavators
- 9-36V DC input supports both 12V and 24V vehicle electrical systems without changing part numbers
Where This Lamp Is Used
- Front lighting on off-road trucks and 4x4 vehicles used in mining and construction zones
- Primary lighting on excavators and cranes operating at night in remote or poorly lit sites
- Auxiliary lighting on tipper trucks and service vehicles used in road maintenance and utility work
- Fleet lighting on buses and engineering vehicles that operate across multiple voltage systems
- Mounting on the front of vessels and boats where vibration and salt exposure degrade standard lights
Who It Is For
- Fleet operators needing consistent lighting across 12V and 24V vehicles with a single part number
- Machinery OEMs integrating lighting into production line builds with tight space constraints
- Distributors sourcing high-performance light bars with proven waterproofing and durability
- 4x4 accessory brands developing private label lighting systems with optimized thermal and optical performance
- Equipment dealers fitting lights on machines used in harsh environments where failures are costly
Problems It Solves
- Screw-mounted front frames on competitor light bars allow water and dust ingress, leading to fogging and early failure
- Low-efficiency LEDs and poor reflector design reduce usable lumen output and create uneven beam patterns
- High-profile light bars interfere with bumper and grill fitment on compact or mid-size vehicles
- Inconsistent voltage tolerance causes flickering or failure in vehicles with unstable electrical systems
- Poor heat dissipation leads to thermal throttling and reduced lifespan in continuous duty applications
Technical Features
- 40 x 6W Osram P8 LEDs with a theoretical output of 20900 lm and actual effective output of 7982 lm
- Combo beam pattern with balanced flood and spot coverage for near and long-distance visibility
- No screw front frame design with sealed bezel for improved waterproofing and faster heat dissipation
- Slim low profile housing with integrated structure reducing separate parts and assembly time
- 9-36V DC input range supports 12V and 24V vehicle systems without voltage conversion
- Die-cast aluminium housing with semi-gloss black powder coating for corrosion resistance
- Integrated heat sink design improves thermal management and maintains lumen output over time
- Bare wire lead of 40cm standard with Deutsch connector available on request
- Operating temperature range of -40 to +60 degrees Celsius for use in extreme climates

How It Compares With the Alternatives
| Standard dual row light bar with screw front frame | No screw design reduces water ingress risk and improves heat dissipation on the front bezel |
|---|---|
| Single row 20 inch light bar | Dual row provides 7982 effective lumens versus lower output in single row models with similar size |
| Light bar with 5000K colour temperature | 6000K provides a cooler white light with better contrast in fog and dust compared to warmer tones |
How to Fit and Use It
- Choose side or bottom mounting based on vehicle bumper or grill clearance before drilling
- Route the 40cm bare wire lead with a drip loop to prevent water from entering the cable gland
- Use a 20A fuse for 12V systems and a 10A fuse for 24V systems to match the amp draw
- Clean the PC lens with water and a soft cloth only—avoid solvents that degrade 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 36V 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.
