Stainless steel 316 LED Underwater Light
The FD-UW020R27 is a 27W or 32W stainless steel 316 underwater luminaire designed for landscape and aquatic applications where long-term submersion and corrosion resistance are required. The fixture is rated IP68 for continuous immersion, with a compact D150 x H185 mm body and a voltage input of AC/DC12V/24V. It offers colour temperatures from 2800K to 6500K, or RGB and RGBW colour options for dynamic lighting effects. The stainless steel 316 body provides structural integrity and resistance to saltwater and chlorinated environments, making it suitable for pools, fountains, canals and marine installations.

Key Benefits
- IP68 rating ensures reliable operation in continuous underwater conditions
- Stainless steel 316 body resists corrosion in saltwater, chlorinated water and high-moisture environments
- Dual voltage input (AC/DC12V/24V) allows compatibility with both low-voltage and mains-powered systems
- Available in 27W or 32W versions to match different light output needs
- Colour options include fixed white (2800K–6500K) and dynamic RGB/RGBW for programmable effects
- Long lift span of at least 50,000 hours reduces maintenance frequency in hard-to-reach underwater positions
Application Scenarios
- Illuminating pool edges, steps and waterfalls in residential and commercial swimming pools
- Lighting fountains, water features and decorative basins in public parks and plazas
- Highlighting underwater architectural elements in canals, moats and marinas
- Creating dynamic lighting effects in water features with RGB or RGBW control
- Providing ambient or accent lighting in outdoor spas and wellness facilities
Who It Is For
- Landscape lighting contractors installing underwater fixtures in pools and fountains
- Architectural lighting designers specifying durable underwater lighting for aquatic features
- Electrical wholesalers supplying waterproof luminaires for aquatic projects in Europe and the Middle East

Problems It Solves
- Standard fixtures with lower-grade materials degrade quickly in chlorinated or saltwater environments
- Lack of IP68 rating leads to early failure in permanently submerged applications
- Incompatible voltage inputs force the use of separate fixtures for 12V and 24V systems
- Fixed colour temperature limits flexibility in dynamic or multi-use water features
- Shorter lifespans require frequent replacement in hard-to-access underwater positions

Compared With the Alternatives
Stainless steel 304 underwater light
316 grade offers better resistance to chloride-induced corrosion, especially in saltwater or chlorinated pools
Aluminium-bodied underwater light
316 stainless steel is more durable in corrosive water environments, though heavier and more expensive
Plastic or coated metal underwater light
Stainless steel 316 maintains structural and aesthetic integrity over time, unlike coatings that can degrade or peel in water
Use Guide
- Install the fixture in a dry environment before submerging to ensure seals are intact
- Use appropriate gaskets and torque settings during installation to maintain IP68 seal
- Ensure the voltage matches the system supply (12V or 24V DC, or AC) to avoid damage
- For RGB/RGBW models, connect to a compatible controller with the correct signal protocol
- Clean the lens periodically during maintenance to maintain light output and clarity
Stainless steel 316 LED Underwater Light Questions
What is the IP rating of this underwater light?
The fixture is rated IP68, which means it is protected against continuous submersion in water.
Can it run on 12V or 24V DC?
Yes. The model supports AC/DC12V/24V input, so it can be used in both low-voltage and mains-powered systems.
Is the driver included?
It can be supplied with or without a driver. The fixture is available with the driver fitted or without, depending on whether the project uses centralised drivers.
What is the warranty period?
This model carries a 2-year warranty. Across the FENGDIAN range, the warranty is 2 to 5 years depending on the product.
What colour options are available?
Available in fixed white (2800K–6500K), RGB, or RGBW for colour-changing effects.
How long is the expected lifespan?
The lift span is at least 50,000 hours, which means the fixture is designed for long-term operation with minimal maintenance.
Can I order a sample before placing a bulk order?
Yes. Sample orders are accepted, mixed samples are acceptable, and samples typically ship within 3-5 days.
