4 Inch 27W Hot Sale Round LED Work Ligh
The SLL-4004 is a 4 inch round LED work light designed for machines operating in harsh environments where consistent illumination is needed after dark and through dust, rain, and vibration. Nine 3W Bridgelux LEDs deliver 2100 effective lumens in a flood or spot beam pattern, providing clear visibility across the work zone on forestry equipment, mining vehicles, and construction machinery. The die-cast aluminium housing with UV resistant powder coating and IP68 sealing ensures long-term durability in outdoor conditions.
- 2100 effective lumens spread evenly across the work area with optional flood or spot beam for different task needs
- IP68 sealing and a durable polycarbonate lens resist water, dust, and impact during daily operation
- 9 to 32V DC operation allows use on both 12V and 24V systems without changing part numbers
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged high load
- 50,000 hour lifespan reduces replacement frequency on machines that run multiple shifts
Where This Lamp Is Used
- Front and side work lighting on forestry and mining vehicles operating in remote areas
- Excavator and loader bucket lighting for night construction tasks in low visibility
- Roadwork vehicle lighting for maintenance crews working after sunset
- Cab and boom lighting on cranes and engineering vehicles where vibration is constant
- Auxiliary lighting on utility and service trucks where electrical stability is variable
Who It Is For
- Distributors of industrial vehicle lighting needing a single part number for 12V and 24V fleets
- Machinery OEMs integrating work lights into production line builds with consistent mounting and wiring
- Fleet operators replacing halogen lights that fail under vibration or in wet conditions
- 4x4 and construction accessory brands developing a private label work light line with beam options
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw excessive current from vehicle electrical systems
- Cheap sealed lights fail after a few wash cycles due to poor cable gland sealing and lens fogging
- Non-IP68 rated lights allow water ingress during pressure washing or rain exposure
- Fixed beam lights with no option for flood or spot limit flexibility on different machine tasks
- Unprotected electronics can fail during voltage spikes common in heavy machinery electrical systems
Technical Features
- Nine 3W Bridgelux LEDs with a total real power draw of 27W and a maximum rating of 30W
- Flood or spot beam pattern available depending on application needs
- Semi-gloss black UV polyester powder coating over the full housing and bracket
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- Overvoltage and overheat protection built into the internal circuitry
- Operating temperature range of -40 to +60 degrees Celsius for extreme climate use

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 stainless steel hardware
- High and low temperature alternating humidity testing across the -40 to +60 degrees Celsius range
Customisation Options
- Deutsch DT connector instead of the standard 40cm bare wire lead
- Spot beam optics in place of the flood pattern
- 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 4 inch work lamp | The same mounting footprint as other 4 inch models but with a flat bottom bracket for secure fit on flat surfaces |
|---|---|
| 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 like cab pillars and guard rails 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
- Choose flood beam for close-range work and spot beam for distance 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, but ECE R10 approval is not listed for this model.
