LED Lights Work Lights
The SLL-0702-16H is a 3.5 inch round LED work light designed for consistent illumination in harsh environments where vibration, dust and water exposure are constant. Sixteen 1W Osram LEDs deliver 1280 effective lumens in a wide flood beam pattern, ensuring the entire work zone around a machine is visible without hot spots. The die-cast aluminium housing with UV-resistant coating and IP68 sealing maintains performance during prolonged outdoor use, while the 9–32V DC operating range allows direct fitment on both 12V and 24V vehicle systems without voltage regulation.
- 1280 effective lumens spread evenly across a wide flood beam, eliminating dark edges around the machine
- IP68 sealing and a sealed cable entry prevent water ingress during pressure washing or heavy rain
- 9–32V DC operation supports both 12V and 24V systems, reducing SKU count for fleet operators
- Die-cast aluminium housing with durable UV polyester powder coating resists corrosion and UV degradation
- Overvoltage and overheat protection extend service life in unstable electrical environments
Where This Lamp Is Used
- Side and rear work lighting on forklifts and loaders operating in dimly lit warehouses or outdoor yards
- Cab roof and hood lighting on trucks and buses used for night delivery or maintenance
- Auxiliary lighting on excavators and engineering vehicles where vibration destroys sealed beam lamps
- Night operation lighting on service vehicles and utility trucks with frequent wash cycles
- Lighting for mining support vehicles exposed to dust, moisture and mechanical shock
Who It Is For
- Distributors of vehicle lighting needing one part number to cover both 12V and 24V systems
- Machinery OEMs integrating work lights into production line builds with consistent mounting patterns
- Fleet operators replacing halogen lights that fail under vibration and draw excessive current
- 4x4 accessory brands developing a private label work light range with proven durability
- Equipment dealers fitting lighting on machines used in agriculture, construction and mining
Problems It Solves
- Halogen work lights fail prematurely under vibration and draw significantly more current than LED alternatives
- Cheap sealed lamps allow water entry through the cable gland, leading to fogging after a few wash cycles
- Narrow beam lights create bright spots but leave the working edges of the machine in shadow
- Non-IP68 rated lights degrade quickly in dusty or wet environments, especially on daily-washed machinery
- Voltage-sensitive lights fail on 24V systems without a regulator, increasing wiring complexity
Technical Features
- Sixteen 1W Osram LEDs with a real power draw of 16W and a maximum rating of 16W
- Wide flood beam pattern with 1280 effective lumens and a 1 lux reading at 50 meters
- 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 internal circuitry
- Operating window of -40 to +85 degrees Celsius, suitable for extreme climates

LED board assembly with Osram emitters
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 reproduce machine mounted service
- Salt spray corrosion testing on housing coating and internal components
- 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
- 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 3 inch work lamp | Higher output and larger lens area in the same mounting footprint, but requires a flat surface for the mounting hole |
|---|---|
| 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 4 inch work lamp | Lower output but fits in tight spaces where a 4 inch body will not clear, such as under cab rails |
How to Fit and Use It
- Mount on a flat surface using the 30mm mounting hole and check the 3.5 inch diameter against the machine bracket before drilling
- 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, suitable for use on machines that operate on public roads.
