LED underwater lights are submersible low voltage fixtures that light ponds, fountains, and water features from below the surface. This category covers fully sealed underwater fixtures rated for continuous submersion on a 12V landscape system.
Underwater lights bring a water feature to life after dark, glowing through moving water and catching spray in a way no above ground fixture can. The critical spec is the submersion rating, since these fixtures live underwater. They are part of the Landscape Lighting family next to LED Well Lights and Landscape Spot Lights, and run on a 12V system with a transformer and wire.
Match the fixture and beam to the water feature and how it will be viewed.
| Feature | Placement | Beam | Notes |
|---|---|---|---|
| Fountains | Below the spray | Upward | Lights moving water |
| Ponds | On the bottom or shelf | Up and across | Watch algae and debris |
| Waterfalls and spillways | Behind or below the flow | Upward | Backlights the sheet |
| Reflecting pools | Low in the pool | Wide | Even glow across the surface |
The one spec you cannot compromise is the submersion rating: an underwater light must be fully sealed and rated for continuous submersion, typically a high IP rating such as IP68. Moving water scatters light, so a modest output reads well. Warm tones feel natural on stone spillways, while cooler tones make clear water pop. Confirm the fixture is rated for your water type and depth.
Place underwater fixtures below the spray or flow and secure them so pumps and current do not shift them. Plan for maintenance access, since lenses need occasional cleaning of algae and mineral film. Run the 12V system within spec and keep connections rated for wet, submerged use. For in-ground uplighting around the feature, pair with LED Well Lights, and for the full system see Landscape Lighting Accessories.
