5 Inch 48W LED Work Light E-Mark Approved
The SLL-5048 is a 5 inch LED work light designed for machines operating in extreme conditions across agriculture, forestry, mining, roadwork and construction. It delivers 3400 effective lumens from 16 x 3W CREE LEDs and is E-Mark approved, which allows it to be used on vehicles that travel on public roads. The die-cast aluminium housing with UV polyester powder coating resists corrosion and impact, while IP68 sealing ensures the lamp remains functional after exposure to water, dust and pressure washing. The 9 to 32V DC operating range supports both 12V and 24V systems, reducing the number of SKUs needed for fleet-wide deployment.
- E-Mark approval enables use on public road vehicles without electrical interference issues
- 16 x 3W CREE LEDs deliver 3400 effective lumens with a 6000K colour temperature for clear visibility in low light
- IP68 sealing prevents water and dust ingress even during high-pressure washing
- 9 to 32V DC input supports both 12V and 24V systems, simplifying inventory for multi-voltage fleets
- 50,000 hour lifespan reduces replacement frequency and maintenance downtime
Where This Lamp Is Used
- Front and side lighting on agricultural tractors and harvesters working at dawn or dusk
- Cab and boom lighting on excavators and loaders in mining and roadwork environments
- Auxiliary lighting on forestry skidders and forwarders operating in remote, wet conditions
- Work area illumination on construction site vehicles and mobile cranes during night shifts
- Fleet lighting on utility trucks and service vehicles that travel on public roads
Who It Is For
- Distributors of vehicle lighting needing one part number for 12V and 24V systems
- Machinery OEMs integrating work lights into production line builds with consistent mounting
- Fleet operators replacing halogen lights that fail under vibration and voltage spikes
- 4x4 and industrial accessory brands developing a private label work light range
- Equipment dealers fitting lights on machines that must pass road inspection in Europe
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw excessive current from the vehicle’s electrical system
- Uncertified auxiliary lights can fail road inspections due to electromagnetic interference
- Cheap sealed lamps let water in through the cable entry and fog up after a few wash cycles
- Narrow beam lights leave the near working area dark while only illuminating a small distance ahead
- Painted metal housings and brackets corrode quickly on machines exposed to rain, salt or chemicals
Technical Features
- 16 x 3W CREE LEDs with a real power draw of 48W and 3400 effective lumens
- Flood or spot beam options available depending on mounting and application
- Die-cast aluminium housing with durable UV polyester powder coating
- Anti-UV, impact-resistant polycarbonate lens with anti-scratch coating
- Overvoltage protection and overheat protection built into the internal circuit
- Operating voltage range of 9 to 32V DC for compatibility with 12V and 24V systems
- Operating temperature range of -40 to +85 degrees Celsius
- IP68 waterproof and dustproof rating with sealed cable entry and gasket
- Standard bare wire lead of 40cm with optional Deutsch connector available

Lens bonding and gasket sealing
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 simulate machine-mounted service
- Salt spray corrosion testing on housing coating and bracket
- High and low temperature alternating humidity testing across the -40 to +85 degrees Celsius range
Customisation Options
- Spot beam optics in place of the standard flood pattern
- Deutsch DT connector instead of the standard 40cm bare wire lead
- Private label logo on the housing and printed carton
- Alternative cable length to match 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 work lamp | The square body provides more LED surface area behind the same mounting footprint but requires a flat mounting surface |
|---|---|
| Spot beam version of the same lamp | Flood covers the near working area evenly while spot reaches further ahead but leaves the machine edges dark |
| Larger 6 inch work lamp | Lower output but fits tight spaces where a 6 inch body would interfere with guards or structural parts |
How to Fit and Use It
- Wire through a fused feed sized for 48W at 12V or 24V and keep the cable entry pointing downward
- Leave a drip loop in the 40cm lead so water runs away from the gland rather than into it
- Select flood beam for near-area work and spot beam for long-distance visibility
- Clean the polycarbonate lens with water and a soft cloth only, as solvents 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.
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 E-Mark approved for electromagnetic compatibility and carries an IP68 sealing rating, which is required for public road use in Europe.
