6.3 Inch 18W Flush Mount Marine LED Work Lamps SLL-6318-18W
The SLL-6318-18W is a 6.3 inch flush mount marine LED work lamp designed for heavy-duty vehicles and machinery that operate in wet, dusty and high-vibration environments. Six 3W Epistar LEDs deliver 1260 effective lumens with a flood or spot beam pattern, providing clear illumination across the work zone without glare. The die-cast aluminium housing is sealed to IP69K, allowing direct exposure to high-pressure water jets and salt spray, which is essential for marine and industrial applications. The lamp is rated for 36 months warranty and operates on 10-30V DC, making it compatible with both 12V and 24V systems.
- IP69K sealing allows operation in high-pressure washdown environments, including marine vessels and construction equipment
- Six 3W Epistar LEDs deliver 1260 effective lumens with a choice of flood or spot beam for flexible lighting coverage
- Vibration-free mount with stainless steel bracket and rubber cushion reduces failure risk on rough terrain and moving machinery
- Flush mount design fits flush with the surface, reducing snagging and improving aerodynamics on vehicles
- 10-30V DC input supports both 12V and 24V fleets, reducing the number of SKUs needed for inventory
Where This Lamp Is Used
- Deck and hatch lighting on fishing boats and service vessels exposed to saltwater and pressure washing
- Cab roof and side lighting on excavators and cranes working in wet or dusty conditions
- Auxiliary lighting on tipper trucks and dump bodies where vibration and water exposure are constant
- Mounting on forklifts and industrial vehicles operating in high-moisture environments like food processing plants
- Work lighting on mining and engineering vehicles where dust, water and shock are common
Who It Is For
- Marine equipment suppliers fitting LED lights on boats and service vessels that require washdown resistance
- Fleet operators maintaining 12V and 24V vehicles with a single lamp model across both systems
- Machinery OEMs integrating a reliable flush mount lamp into production line builds
- Distributors seeking a durable work lamp with a long warranty for resale to industrial users
- 4x4 accessory brands developing a marine-rated lighting line with vibration-resistant mounting
Problems It Solves
- Standard sealed lamps fail after repeated high-pressure washdowns due to inadequate sealing at the cable entry
- Cheap brackets loosen under vibration, causing the lamp to fall off or misalign on moving machinery
- Halogen or low-lumen LED lamps do not provide sufficient visibility in dark or wet conditions
- Non-flush mount lamps create protrusions that catch on cargo, guard rails or overhead structures
- Lamps not rated for 10-30V DC require different SKUs for 12V and 24V fleets, increasing inventory complexity
Technical Features
- Six 3W Epistar LEDs with a real power draw of 18W and a maximum rating of 20W
- Semi-gloss black powder coating over the full housing and bracket
- Mounting pattern designed for flush installation on flat or slightly curved surfaces

How It Compares With the Alternatives
| Standard 6 inch flush mount lamp | The 6.3 inch size fits flush with standard mounting holes but has a wider beam pattern than older models |
|---|---|
| Flood beam version | The spot beam extends visibility further ahead but leaves the near working area less evenly lit |
| Non-flush mount lamp | Flush mount reduces protrusion and snag risk on vehicles with tight clearance |
| Lamp with plastic bracket | The stainless steel bracket with rubber cushion resists vibration and corrosion better than plastic |
How to Fit and Use It
- Aim the flood beam at the near work zone or the spot beam at distance, depending on the task
- Clean the PC lens with water and a soft cloth only, since solvents will haze the anti-scratch coating
