Top 5 Mistakes to Avoid When Installing Landscape Lighting in Canada

Have you ever spent a weekend installing landscape lighting, only to watch it flicker out after the first Canadian frost? If so, you’re not alone. Landscape lighting installation in Canada can transform your yard into a safe, stunning oasis—but only if it’s done right. Between harsh winters, unpredictable weather, and the unique needs of outdoor spaces, there’s plenty that can go wrong. That’s why we’re here to help you sidestep the pitfalls and get it right the first time.

At Silhouette Lights, we’ve seen countless homeowners and DIY enthusiasts tackle outdoor lighting in Canada with enthusiasm, only to hit roadblocks that dim their results. In this post, we’ll walk you through the top five DIY landscape lighting mistakes to avoid, plus practical tips to ensure your setup shines bright all year long. Whether you’re illuminating a pathway or spotlighting your favorite tree, steering clear of these errors will save you time, money, and frustration. Ready to make your yard glow with low voltage lighting that lasts? Let’s dive in.

Mistake 1: Undersizing Your Transformer for Landscape Lighting

One of the biggest blunders in landscape lighting installation Canada is picking a transformer that’s too small for the job. A transformer powers your low voltage lighting system, converting household voltage to a safe 12V output. But if it’s undersized, it can’t handle the total wattage of your lights—leading to flickering, burnout, or a system that just won’t turn on.

Why does this happen so often? Many DIYers underestimate their setup’s power needs, especially in Canada where longer cable runs and cold weather can strain performance. The fix is simple: calculate your total wattage (add up all your fixtures’ power draw) and choose a transformer with at least 20% extra capacity. For example, if your lights total 80 watts, go for a 100-watt transformer.

At Silhouette Lights, our low voltage transformers are built to handle Canadian conditions, with durable designs that keep your landscape lighting humming through snow and rain.

Mistake 2: Poor Placement of Outdoor Lighting Fixtures

Ever seen a yard where the lights are swallowed by overgrown shrubs or leave dark patches on the walkway? That’s the result of poor fixture placement—one of the sneakiest landscape lighting installation mistakes. In outdoor lighting Canada, where safety and aesthetics go hand in hand, placement is everything.

The problem often starts with guesswork. Lights placed too close to plants get blocked as foliage grows, while fixtures aimed too high create glare instead of ambiance. Skipping key areas like steps or driveways can even turn your yard into a hazard. To avoid this, plan your layout with purpose: use path lights for walkways, spotlights for trees or features, and soft accents for seating areas. Test your setup at night before digging in permanently.

Silhouette Lights offers versatile, adjustable fixtures that make perfect placement a breeze. Our premium LED landscape lights let you tweak angles and positions to suit your space. 

Mistake 3: Ignoring Weather Resistance in Landscape Lighting

Canada’s weather doesn’t mess around—rain, snow, and freeze-thaw cycles can wreak havoc on poorly built landscape lighting. Ignoring weather resistance is a classic DIY landscape lighting mistake that leads to rusted fixtures, cracked lenses, and costly replacements. If your lights aren’t built for the elements, they won’t last a single season.

The solution? Prioritize durability. Look for fixtures with an IP65 rating (or higher) for water and dust resistance, and opt for corrosion-resistant materials like aluminum or brass. This is especially critical in landscape lighting Canada, where winter storms and summer humidity test even the toughest gear.

Here’s where Silhouette Lights shines. Our Canadian-made weather-resistant outdoor lighting is engineered to withstand the toughest conditions, from -40°C winters to soggy springs. Pair them with our rugged transformers, and you’ve got a system that laughs at the forecast. Curious about maintenance? Our post on Caring for Your Landscape Lights Year-Round has you covered.

Mistake 4: Overlooking Voltage Drop in Low Voltage Lighting

Voltage drop is a silent killer in low voltage lighting tips that too many DIYers overlook. It happens when power weakens over long cable runs, leaving lights at the end of the line dim or lifeless. In landscape lighting installation Canada, where sprawling yards and big properties are common, this mistake can ruin an otherwise flawless setup.

Why does voltage drop matter? In a 12V system, even a small loss can sap brightness, especially over distances beyond 50 feet. To fix it, use a multi-tap transformer (with outputs like 12V, 13V, or 14V) to compensate, or keep cable runs short by splitting your layout into zones. A quick formula: Voltage Drop = (Watts x Distance) ÷ Cable Constant (use 7500 for 12-gauge wire).

Silhouette Lights’ low voltage lighting systems are designed with voltage drop in mind, offering multi-tap options and high-efficiency LEDs that stay bright. For a step-by-step breakdown, read our Beginner’s Guide to Low Voltage Lighting.

Mistake 5: Skipping a Lighting Plan for Your DIY Project

Jumping into DIY landscape lighting without a plan is like building a house without a blueprint—it’s a recipe for chaos. Without a clear design, you might overspend on fixtures, miss key areas, or end up with a patchy glow that disappoints. This is one of the most common DIY landscape lighting mistakes, and it’s totally avoidable.

Start by sketching your yard and marking priorities: safety (paths, stairs), ambiance (patio, garden), or highlights (trees, architecture). Decide how many fixtures you need and where they’ll go—then test with a temporary setup. A little planning upfront saves hours of rework later.
