Work LED Light 3.5 Inch 16W 1280 LM
The SLL-0702-16 is a 3.5 inch round LED work light designed for vehicles and machinery that operate in harsh conditions with frequent vibration, dust, and water exposure. It delivers 1280 effective lumens using 16 x 1W Osram LEDs, providing broad, even illumination across the work area instead of a narrow hotspot. The die-cast aluminium housing with UV-resistant powder coating and IP68 sealing ensures long-term durability in off-road, marine, and industrial environments.
- 1280 effective lumens from 16 x 1W Osram LEDs cover a wide work area without hotspots
- IP68 sealing and a durable polycarbonate lens resist water, dust, and impact during daily use
- 9 to 32V DC operating range supports both 12V and 24V systems, reducing SKU count
- Overvoltage and overheat protection prevent damage from electrical surges or prolonged use
- Die-cast aluminium housing with UV-resistant powder coating resists corrosion and fading
Where This Lamp Is Used
- Front and side work lighting on ATVs and UTVs operating in wet or dusty terrain
- Cab and hood lighting on trucks and utility vehicles used in night delivery or maintenance
- Deck and cargo area lighting on boats and marine service vehicles exposed to salt spray
- Auxiliary lighting on excavators and loaders where vibration destroys standard sealed lamps
- Lighting on forklifts and industrial vehicles that operate in warehouses with high humidity
Who It Is For
- Distributors of 12V and 24V vehicle lighting needing one part number for both systems
- Machinery OEMs fitting work lights on production lines with consistent mounting patterns
- Fleet operators replacing halogen lights that fail under vibration and draw excessive current
- 4x4 and marine accessory brands building a private label work light range
- Equipment dealers fitting lights on machines used in mining, agriculture, and construction
Problems It Solves
- Halogen work lights burn out quickly under vibration and draw more current than LED alternatives
- Cheap sealed lamps allow water ingress through the cable entry and fog up after repeated wash cycles
- Narrow beam lights create a bright spot but leave the edges of the work area in shadow
- Lights with no overvoltage protection fail during alternator surges or battery jump starts
- Painted metal housings fade and corrode in saltwater or high humidity environments
Technical Features
- 16 x 1W Osram LEDs with a real power draw of 16W and 1600 raw lumens
- Wide flood beam pattern with effective output of 1280 lumens at 1 lux
- Semi-gloss black UV-resistant polyester powder coating over the full housing
- Bare wire lead of 40cm as standard with overvoltage and overheat protection built in
- Operating voltage range of 9 to 32V DC, suitable for 12V and 24V systems
- Rated for -40 to +85 degrees Celsius, suitable for extreme cold and hot climates

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
- Deutsch 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 12W work lamp | Higher output and wider beam but requires a larger mounting surface |
|---|---|
| Spot beam version of the same lamp | Flood covers the near work area evenly while spot reaches further ahead but leaves the machine edges dark |
| Larger 4 inch 24W work lamp | Higher output but may not fit on compact machine brackets or guard rails |
How to Fit and Use It
- Mount on a flat surface using the 30mm bracket width and check clearance 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, with IP68 sealing and overvoltage protection, suitable for use on vehicles used on public roads.
