5 Inch 45W Industrial LED Work Light EMC CISPR 25 CLASS 4
The SLL-5451 is a 5 inch industrial LED work light designed for heavy machinery that operates in extreme conditions and requires reliable lighting without electrical interference. Nine 5W Osram LEDs deliver 3150 effective lumens in a flood beam pattern, providing even illumination across the work zone of a crane, excavator or forklift. The die-cast aluminium housing with IP68 sealing resists water, dust and vibration, while the EMC CISPR 25 CLASS 4 rating ensures the light does not disrupt nearby electronic systems on the machine.
- 3150 effective lumens in a flood beam pattern cover the entire work area without hot spots
- IP68 sealing and a durable polycarbonate lens prevent water and dust ingress during washdowns
- EMC CISPR 25 CLASS 4 compliance prevents electrical interference with machine control systems
- 9 to 32V DC operation allows use on both 12V and 24V industrial vehicles without voltage regulation
- Overvoltage and overheat protection extend lamp life in unstable electrical environments
Where This Lamp Is Used
- Front and side work lighting on excavators and cranes operating in night shifts
- Cab and boom lighting on forklifts and engineering vehicles in dusty or wet environments
- Auxiliary lighting on mining machinery where electrical noise can disrupt sensors
- Loading and unloading area lighting on tipper trucks and service vehicles
- Night operation lighting on vessels and boats where vibration and salt exposure are constant
Who It Is For
- Machinery OEMs integrating lighting into production line builds with consistent electrical performance
- Fleet operators replacing halogen lights that fail under vibration and cause EMI
- Distributors sourcing a single model for 12V and 24V systems with a wide voltage tolerance
- 4x4 and industrial accessory brands building a private label range with EMI compliance
- Equipment dealers fitting lights on machines used in mining, construction and marine sectors
Problems It Solves
- Halogen work lights fail under vibration and draw excessive current, overloading alternators
- Cheap LED lights without EMI protection cause interference with onboard sensors and control units
- Water and dust ingress through poor seals leads to fogging and early failure after wash cycles
- Narrow beam lights leave the near edge of the machine dark, creating safety blind spots
- Voltage fluctuations in 24V systems damage lights not rated for 9–32V DC input
Technical Features
- Nine 5W Osram LEDs with a real power draw of 45W and a maximum rating of 45W
- Flood beam pattern with effective output of 3150 lumens
- Semi-gloss black durable UV polyester powder coating on the full housing
- Bare wire lead of 40cm as standard with Deutsch connector available on request
- Overvoltage and overheat protection circuits integrated into the driver
- Operating window of -40 to +85 degrees Celsius for extreme climate use
- EMC protected wiring and compliance with CISPR 25 CLASS 4 for vehicle electronics

How This Lamp Is Built
Die casting of the aluminium housing and heat sink
Powder coating in semi-gloss black with UV resistance
LED board assembly with Osram emitters and driver integration
Lens bonding and gasket sealing with IP68 integrity check
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 bracket
- High and low temperature alternating humidity testing across the -40 to +85 degrees Celsius range
- EMC testing to confirm CISPR 25 CLASS 4 compliance
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 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 work lamp | The square body puts more LED area behind the same mounting footprint but needs a flat surface for the bottom bracket |
|---|---|
| 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 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 flood beam at the working area close to the machine and use a spot lamp separately for distance
- 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 EMC CISPR 25 CLASS 4 approval for electromagnetic compatibility, together with an IP68 sealing rating.
