15. Ground-Embedded Up-Lights for Trees
If you have a specimen tree (like a Japanese Maple) in your courtyard, light it from below. The light will bounce off the canopy and create a natural umbrella of soft light over the pool.
How to make it: Use a well-light (an in-ground fixture) aimed at the trunk and canopy of the tree.
Ingredients needed: Waterproof brass or heavy-duty plastic well-lights, LED bulbs (narrow beam), exterior-rated underground cable.
