Every October, we get calls from homeowners who tried to tackle outdoor lighting projects themselves and hit unexpected snags. The good news? Most of these issues are totally preventable with a little planning. Here are the mistakes we see most often – and what to do instead.
Mistake #1: Thinking "Weatherproof" Means "New England Winter-Proof"
Just because a fixture says “outdoor rated” doesn’t mean it can handle what Mother Nature throws at us here. We’ve seen plenty of “waterproof” lights that worked fine through September and October, then failed spectacularly during the first winter storm.
The reality is that New England weather is tough on everything, but especially electrical components. Temperature swings from 70 degrees to below freezing, driving rain, ice, snow loads on fixtures – it all adds up. Professional-grade fixtures and proper installation methods make the difference between lighting that lasts one season and lighting that’s still working five years later.
What to do instead: Look for fixtures specifically rated for harsh climates, and more importantly, have them installed with proper weatherproofing techniques that account for ice expansion, wind loads, and moisture infiltration.
Mistake #2: Running Extension Cords Instead of Installing Real Outlets
We get it – you want to add some patio heaters or string lights, and running an extension cord from the house seems like the simple solution. But outdoor extension cords are meant for temporary use, not as permanent power sources. They create tripping hazards, they’re not weatherproof at the connections, and they’re often not rated for the electrical load you’re putting on them.
Worse, many people don’t realize they need GFCI protection for outdoor electrical devices. A regular household outlet won’t cut it outside.
What to do instead: Install proper GFCI-protected outdoor outlets where you actually need power. It costs more upfront but eliminates safety hazards and gives you reliable power for years to come.
Mistake #3: DIY Low-Voltage Installation (Getting the Voltage Wrong)
Low-voltage landscape lighting seems DIY-friendly, and plenty of big box stores sell kits that make it look simple. The problem is that proper low-voltage installation requires understanding voltage drop, load calculations, and wire sizing. Get it wrong, and your lights at the end of the run will be dim or won’t work at all.
We’ve seen homeowners spend hundreds on landscape lighting only to have half the lights barely glow because the transformer is undersized or the wire runs are too long for the gauge they used.
What to do instead: Even with low-voltage systems, having an electrician design the layout ensures your lights actually work as intended. They’ll calculate proper wire sizes, transformer capacity, and placement to get consistent light output across the whole system.
Mistake #4: Installing Lights Without Thinking About Maintenance
This is a big one. People get so focused on how the lighting will look that they don’t consider how they’ll change bulbs, clean fixtures, or make adjustments later. We’ve seen beautiful installations that require a ladder and 20 minutes just to replace one bulb.
Similarly, burying junction boxes or using cheap fixtures that can’t be easily serviced means simple maintenance becomes major projects.
What to do instead: Plan for accessibility from day one. Choose fixtures that can be easily maintained, and make sure junction boxes and connections are accessible but protected. Your future self will thank you.
Mistake #5: Timing Installation Too Late in the Season
Here’s one that surprises people: waiting until it’s already dark and cold to install outdoor lighting. November installations are certainly possible, but they’re more challenging for everyone involved. Cold weather makes materials less flexible and shorter daylight hours mean longer project timelines.
Plus, you miss out on enjoying the system during those perfect early fall evenings when you’d actually want to be outside.
What to do instead: Plan outdoor electrical projects for September or early October when weather is still cooperative and you can test everything during those golden hour evenings when you’ll actually use it.
Mistake #6: Overlighting Everything
More isn’t always better with outdoor lighting. We’ve seen homeowners install so many lights that their backyard looks like a shopping center parking lot. Good outdoor lighting is about creating ambiance and highlighting specific features, not eliminating every shadow.
Overlighting also creates practical problems – glare that makes it harder to see, light pollution that bothers neighbors, and higher energy bills.
What to do instead: Start with less and add more if needed. Focus on key areas like pathways, gathering spots, and architectural features. Use dimmers or multiple switching zones so you can adjust the mood based on how you’re using the space.
Mistake #7: Ignoring Your Neighbors
Outdoor lighting affects more than just your property. Poorly aimed spotlights can shine directly into neighbors’ windows or create glare for drivers. It’s not just about being considerate – many towns have light pollution ordinances that can require you to modify or remove problematic fixtures.
What to do instead: Consider sight lines and potential glare issues during the planning phase. Good lighting design illuminates your space without creating problems for others.
The Real Cost of DIY Mistakes
Here’s what many people don’t realize: fixing outdoor electrical problems is often more expensive than doing it right the first time. Troubleshooting voltage issues, replacing failed fixtures, or redoing unsafe installations can easily cost more than professional installation would have initially.
Beyond the money, there’s the frustration factor. Nothing ruins the enjoyment of your outdoor space like lights that don’t work reliably or electrical issues that leave you in the dark.
Getting It Right From the Start
The best outdoor lighting projects start with realistic expectations and proper planning. Understanding what’s involved, what can go wrong, and what solutions actually work long-term saves both money and headaches.
If you’re thinking about outdoor lighting upgrades this fall, talking through your ideas with a professional electrician can help you avoid these common pitfalls and end up with a system you’ll actually enjoy using. At Corrao Electric, we’ve seen all these mistakes firsthand, and we’re always happy to help homeowners get it right the first time.
After all, the goal is enjoying those beautiful New England fall evenings, not troubleshooting electrical problems in the dark.
