5 Inch 45W 3 600 LM 6000K
The SLL-5044 is a 5 inch spot beam driving light built for off-road vehicles that need to see far ahead in rain, fog, and dust. It uses nine 5W Osram LEDs to deliver 3600 effective lumens in a focused beam, so an operator on a 4x4 or mining vehicle can detect distant obstacles before reaching them. The die-cast aluminium housing is sealed to IP68 and carries overvoltage and overheat protection, which prevents failure during electrical surges or prolonged use. The lamp operates on 9-32V DC, so it works on both 12V and 24V systems without changing the part number.
- 3600 effective lumens in a spot beam pattern illuminate distant obstacles on dark off-road trails
- IP68 sealing and a stainless steel U bracket resist water, dust, and vibration in harsh environments
- Overvoltage and overheat protection prevent electrical damage during unstable power supply or high ambient temperatures
- 9-32V DC operation allows one part number to serve both 12V and 24V off-road fleets
- 50000 hour lifespan means replacement is measured in years, not months
Where This Lamp Is Used
- Front lighting on 4x4s and off-road trucks navigating unlit forest tracks
- Auxiliary lighting on excavators and mining machinery operating in low visibility conditions
- Long-range visibility on utility vehicles and service trucks used in remote areas
- Night driving on construction sites where road surfaces are uneven and poorly lit
- Backup lighting on heavy machinery where a single bright beam is needed to clear the path ahead
Who It Is For
- Distributors of off-road vehicle lighting needing one part number for 12V and 24V systems
- 4x4 accessory brands building a private label driving light range with consistent performance
- Fleet operators replacing halogen driving lights that fail under vibration or heat
- Machinery OEMs fitting driving lights on production line vehicles with a repeatable mounting pattern
- Equipment dealers supplying lighting for mining and construction machinery used in extreme conditions
Problems It Solves
- Halogen driving lights burn out quickly under vibration and draw more current than LED alternatives
- Cheap LED lights fail in rain or fog due to poor sealing and lack of IP68 protection
- Unprotected electronics can be damaged by voltage spikes from alternators or battery jumps
- Narrow beam lights leave the immediate area dark while wide beams don’t reach far enough
- Painted brackets rust in salt-laden air or after frequent washdowns on construction equipment
Technical Features
- Nine 5W Osram LEDs with a real power draw of 45W and 45W maximum rating
- Semi-gloss black powder coating over the full housing and bracket
- Bare wire lead of 40cm as standard with a Deutsch connector available on request
- Overvoltage and overheat protection built into the driver circuit
- Operating window of -40 to +85 degrees Celsius, suitable for extreme climates
- 9-32V DC input range covers 12V and 24V vehicle systems without part number change

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 off-road 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
- Flood beam optics in place of the spot 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 5 inch driving light | The square body puts more LED area behind the same mounting footprint but needs a flat surface for the bottom bracket |
|---|---|
| Flood beam version of the same lamp | Spot reaches further ahead while flood covers the near area evenly but does not extend as far |
| Larger 6 inch driving light | Lower output but fits guard rails and cab pillars where a 6 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 spot beam at the farthest point of visibility and use a flood lamp separately for near-field illumination
- 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 and RoHS compliant and carries IP68 sealing, which meets requirements for off-road and public road use in many regions.
