  2. Downlighting: Downlighting shines downward, creating a soft, diffused glow that's perfect for highlighting plants, rocks, or other decorative elements in your pond.
  3. Crosslighting: Crosslighting involves positioning lights at an angle to create interesting patterns and shadows. This technique can be used to draw attention to specific features or create a dynamic, engaging display.
