Underwater LED Silicone Strip Light
IP68 full waterproof design for long-term underwater immersion.
Product Overview
An underwater LED silicone strip light designed for continuous contour lighting in pools, fountains, aquariums and spas where long-term immersion is required. The full IP68 sealing prevents water ingress even under constant submersion, and the integrated injection-molded silicone housing provides a seamless, corrosion-resistant body. Flexible and bendable into complex shapes, the strip maintains its integrity in dynamic water environments. Powered by low-voltage DC 24V, it is safe for use in wet and humid zones. Available in 2835 SMD or 2012 SMD with colour temperature from 2700K to 6500K, or RGB, and CRI Ra above 80 or 90, with lumen output per watt above 90 lm/W.
Key Benefits
- IP68 rating ensures full waterproofing for long-term underwater immersion
- Integrated injection-molded silicone housing eliminates seams and entry points for water
- Flexible silicone body allows shaping into curves and contours for pool and fountain edges
- Corrosion-resistant, anti-UV and anti-fouling materials withstand prolonged water exposure
- Low-voltage DC 24V supply reduces electrical risk in wet environments
- Lumens per watt above 90 lm/W delivers efficient light output with minimal power draw
- CRI Ra >80 or >90 ensures accurate colour rendering in aquarium and spa lighting
- No visible joints or seams due to one-piece silicone encapsulation, maintaining a clean appearance
Problems It Solves
- Standard LED strips fail quickly when submerged due to inadequate sealing or material degradation
- PVC or non-encapsulated strips develop leaks or degrade under UV and chlorinated water
- Low CRI lighting distorts colours in aquariums and makes aquatic life appear dull
- High-voltage systems pose safety risks in wet environments, especially in pools
- Fixed cut lengths and inflexible profiles limit installation options in curved or irregular water features
- Visible joints or seams in multi-piece strips create weak points and water entry paths
Application Scenarios
- Swimming pool contour lighting along the waterline or steps where the strip is permanently submerged
- Fountain and water feature lighting where the strip is installed in flowing or splashing water
- Aquarium landscape lighting to highlight coral, plants and underwater structures
- Spa and hot tub ambient lighting where the strip is exposed to constant moisture and heat
- Indoor or outdoor waterfalls with continuous lighting along the water channel
- Landscape water features in gardens or public spaces requiring durable underwater fixtures
- Commercial aquatic displays where long-term reliability and safety are critical
Who It Is For
- Aquatic lighting contractors specifying durable underwater fixtures for pools and spas
- Aquarium suppliers needing reliable, low-maintenance lighting for display tanks
- Fountain and landscape designers integrating lighting into water features
- Commercial project buyers sourcing safe, long-term underwater lighting solutions
- OEM brands developing waterproof lighting systems for aquatic environments

Honest Comparison
How It Compares With the Alternatives
| PVC-based underwater strip | Silicone maintains flexibility and UV resistance over time; PVC becomes brittle and cracks in water |
|---|---|
| Standard IP65 strip | IP68 allows full submersion; IP65 is only splash-proof and not rated for long-term immersion |
| Bare SMD strip in a sealed housing | Integrated injection molding eliminates joints and weak points; sealed housing can still leak over time |
Use Guide
Getting the Best Out of It On Site
- Install only in fully submerged or covered water environments; not for outdoor exposure to rain without enclosure
- Avoid sharp bends below the minimum radius to prevent stress on the silicone encapsulation
- Use DC 24V power supply only; do not use AC or higher voltage sources
- Ensure all connections are made with waterproof connectors to maintain IP68 rating
- Clean the strip periodically to prevent algae or mineral buildup in high-usage environments
- Do not use in saltwater unless specifically rated; verify compatibility with water chemistry

Can the LED density and cut length be customised?
Yes. LED quantity is adjustable within the 10W to 14.4W range, and the strip is cut and terminated to your specified run lengths.
Which voltage should I order?
DC 24V is standard. It is recommended for underwater use due to safety and lower voltage drop in long runs.
Is this strip suitable for saltwater or chlorinated pools?
