How to Properly Light a Tree (And Why It’s Trickier Than You Think)

Tree lighting can instantly transform your yard. A beautifully lit tree adds depth, drama, and a warm glow to your landscape. Whether you're highlighting a majestic oak, a graceful birch, or a small ornamental tree, the right lighting brings it to life after dark.

If you're considering a tree lighting project, here are a few design tips to help you begin:

1. Start with a Purpose

Ask yourself:

• Are you trying to show off the tree’s structure?
• Add curb appeal?
• Improve safety or nighttime visibility?

Different goals mean different lighting choices.
For structure and drama, uplighting works best. For soft ambience, a wide-beam wash might be better.

2. Pick the Right Fixtures (And the Right Number)

There’s no “one fixture fits all.” Here’s a general guide:

• Small trees (under 15 feet): 1–2 uplights
• Medium trees (15–25 feet): 2–3 uplights, placed at varying angles
• Large trees (25+ feet): 3+ uplights, plus optional downlights from within the canopy

Choose fixtures made from brass or stainless steel for durability.

3. Beam Angles and Bulb Brightness Matter

• Narrow beam (15°–25°): Tall, narrow trees or trunks
• Wide beam (40°–60°): Branches and canopies
• Use warm white LEDs (2700K–3000K) for natural appearance
• Always go with low voltage (12V) for safety and efficiency

4. Think Like a Designer (Not Just an Installer)

Lighting is about how light paints the space. A pro will:

• Use multiple angles to add depth
• Highlight textures in bark and leaves
• Avoid glare and hot spots
• Create transitions, not contrasts

5. Common Tree Lighting Mistakes

• Too few or too many lights
• Lights that are too bright
• Fixtures placed too close to the trunk
• Ignoring surrounding features
• Forgetting to consider voltage drop

These missteps can result in poor appearance or long-term damage.

6. Use Care with Downlighting and Moonlighting Effects

Downlighting from within the tree canopy—sometimes called moonlighting—can create a beautiful, natural glow that mimics soft moonlight filtering through the branches. It’s especially effective for wide trees or areas like patios and walkways beneath the tree.

But this technique comes with a few important considerations:

• Use tree-safe mounting hardware that won’t damage the bark or restrict growth.
• Choose non-invasive wiring methods to avoid cutting into or wrapping around limbs.
• Plan for growth—branches will move, thicken, and shift over time, so fixtures may need periodic adjustment.

Proper installation protects the health of the tree and ensures your lighting remains beautiful and functional as the tree matures.

Lighting a tree might seem simple, but thoughtful design makes all the difference. From choosing the right number and type of fixtures to considering beam angles, brightness, and placement, every detail affects the final look. It’s not just about making a tree visible at night—it’s about creating mood, highlighting natural beauty, and adding depth to your landscape.
