4x6 45W Flush Mount Convex Lens High Low Beam LED Head Light
The SLL-5045 is a 4x6 inch flush mount LED headlight designed to replace original headlights on off-road vehicles, excavators, and industrial machinery that operate in extreme conditions. It uses 15 Bridgelux 3W LEDs to deliver 3150 effective lumens with a high-low beam option, ensuring visibility in both close and distant terrain. The die-cast aluminium housing with UV polyester powder coating resists corrosion, while IP68 sealing prevents water and dust ingress during pressure washing or heavy rain. Overvoltage and overheat protection extend service life in unstable electrical environments.
- 3150 effective lumens from 15 Bridgelux 3W LEDs provide clear visibility in high and low beam modes
- Flush mount design fits original headlight housing without body modifications
- IP68 sealing ensures operation in heavy rain, dust storms, and pressure wash cycles
- 9 to 32V operating range supports both 12V and 24V systems across fleets
- Overvoltage and overheat protection prevent damage from electrical spikes or blocked airflow
Where This Lamp Is Used
- Replacements for original headlights on excavators and cranes working in wet or dusty environments
- High-low beam lighting on off-road vehicles and 4x4s used in mining or forestry operations
- Front lighting on forklifts and engineering vehicles where flush mounting avoids interference
- Auxiliary lighting on utility trucks and service vehicles that operate at night in variable weather
- Headlight upgrade on older machinery where halogen units fail under vibration or moisture
Who It Is For
- Machinery OEMs fitting LED headlights during production with a direct drop-in replacement
- Fleet operators replacing halogen headlights that fail under vibration or in wet conditions
- Distributors sourcing a single model with high-low beam for multiple vehicle types
- 4x4 accessory brands building a private label headlight line with flush mount compatibility
- Equipment dealers offering a direct replacement for original equipment headlights
Problems It Solves
- Original halogen headlights burn out quickly under vibration and moisture exposure
- Non-sealed LED headlights fog up or fail after a few pressure wash cycles
- Narrow beam or low lumen output leaves operators unable to see terrain edges at night
- Voltage fluctuations in 12V and 24V systems damage unprotected LED drivers
- Bulky or protruding headlights interfere with body panels or protective guards
Technical Features
- 15 Bridgelux 3W LEDs with a total real power draw of 45W and 3150 effective lumens
- High and low beam beam pattern option for close and distant visibility
- Semi-gloss black UV polyester powder coating over the full housing and mounting flange
- Flush mount design with a 4x6 inch footprint matching original headlight dimensions
- Overvoltage protection and overheat protection circuits for electrical stability
- Operating window of -40 to +60 degrees Celsius for cold and hot climate operation
- Bare wire lead of 40cm as standard with no connector included
- IP68 sealing rated for immersion in water and dust ingress resistance

How It Compares With the Alternatives
| Round 4 inch LED headlight | The 4x6 inch flush mount fits original rectangular housings and provides more LED area behind the same footprint |
|---|---|
| Standard flush mount LED headlight without overheat protection | This model includes overheat protection, which prevents failure in enclosed or poorly ventilated headlight housings |
| LED headlight with only high beam | The optional low beam mode improves visibility in tight spaces and reduces glare for oncoming traffic |
How to Fit and Use It
- Verify the 4x6 inch flush mount footprint matches the original headlight housing before installation
- Leave a drip loop in the 40cm lead so water runs away from the gland rather than into it
- Use the high beam for long-distance visibility and low beam for close-up work or oncoming traffic
- Clean the polycarbonate lens with water and a soft cloth only, since solvents will degrade the anti-UV coating
Questions About This Model
Can I order a sample before placing a bulk order
