The Complete Guide to Permanent LED Soffit Lights
Want to make your home look incredible after dark? Permanent LED soffit lights are changing the way homeowners think about exterior lighting. At Éclairage Extérieur Montréal, we work with these systems. This guide covers everything you need to know — from how they work to how much you can save.
What Are Permanent LED Soffit Lights?
The soffit is the underside of your roof overhang — the flat panel that runs between the wall and the edge of your roof. Soffit lights are fixtures installed right there, shining light down your walls and onto the ground below. The effect at night is striking.
For years, homeowners used standard bulbs spaced 4 to 8 feet apart along the soffit. The problem? Uneven light. You’d see bright patches, then dark spots, then the bulbs themselves. It wasn’t a clean look.
Today, permanent LED soffit lights use a continuous system — a track installed along the soffit with LEDs spaced evenly throughout. The result is smooth, professional lighting that runs the full length of your home.
Why LED Makes All the Difference
Switching to LED isn’t just about looks. The practical benefits are hard to ignore.
They last an incredibly long time. Quality LEDs are rated for 25,000 to 50,000 hours of use. Run them 7 hours a day and you’re looking at close to 20 years of life — roughly 25 times longer than a standard bulb.
The energy savings are real. LEDs use 70% to 90% less electricity than traditional bulbs. We’ll show you exactly what that means for your wallet in a moment.
They’re built for Canadian winters. Permanent LED soffit lights handle temperatures from -40°C to +50°C without a problem. Freeze-thaw cycles, heavy snow, rain, UV exposure — these systems are designed for it all.
Control is simple. Modern systems connect to your home WiFi. You adjust brightness, switch colours, and set schedules right from your phone or tablet.
Your Options: DIY vs. Professional Systems
There are two types of permanent LED soffit lights on the market.
DIY-friendly brands are designed for homeowners who like to tackle projects themselves. Govee is one of the most accessible, ranging from $2 to $5 per linear foot — roughly $300 to $750 for a typical 150-foot installation. There’s also Illumidel that offers a more complete aluminum track kit at around $2,900 for 150 linear feet, including the power supply and controller. Both are available through Amazon, Costco, or directly from the brands. Illumidel also sells through a dealer network for professional installs.
Professional-grade systems like Gemstone Lights, Celebright, Chromaglow, and Illumidel(DIY as well) have a network of dealers and are installed by certified technicians. Installation costs typically run $22 to $35 per linear foot, plus $300 to $600 for the power supply and controller. If the job requires a lift, budget an additional $350 to $500 per day.
At Éclairage Extérieur Montréal, we are an authorized Gemstone Lights dealer. Gemstone Lights has been leading this category since 2016. Their system uses a continuous aluminum track mounted along the soffit near the fascia, with lights positioned every 9 inches(they can also have custom track made and custom spacing done upon request) All wiring runs inside the track — nothing is exposed. For the cable run from the power supply up to the soffit, we use a small colour-matching aluminum track that blends into your home’s exterior materials. We never run wires through gutters.

Other brands like Chromaglow offer different spacing options, ranging from 4 to 18.5 inches depending on the model.
Picking the Right Colour Temperature
This is one of the most important decisions you’ll make — and one of the most commonly rushed. The colour temperature of your permanent LED soffit lights completely changes how your home feels at night.
For security and visibility: Neutral white (4000K–4500K) gives you a clean, balanced light that works well near entrances, outdoor kitchens, and parking areas. Cool white (5000K–6500K) is the brightest option — excellent for driveways, garages, and surveillance zones.
For ambiance and warmth: Very warm white (2800K–3000K) creates that soft, candle-like glow. It’s intimate and relaxing — ideal for patios, terraces, and entertaining spaces. Standard warm white is slightly brighter but still welcoming, great for hosting guests and outdoor lounging areas.
For highlighting architecture: Warm white (2800K–3000K) draws out the texture of your materials and adds depth. Neutral white (4000K) shows details clearly — often used on commercial properties.
Take your time with this choice. The colour you pick will transform your property. Getting it wrong is a costly mistake.
The 3 Most Common Soffit Lighting Mistakes
Mistake 1 — Wrong colour temperature. Too many homeowners choose without thinking about how they use the space. Warm isn’t always better. Cool isn’t always better. It depends on your home, your materials, and what you want the lighting to do.
Mistake 2 — Too much brightness. Glare is a real problem. If your lights are too powerful, they’ll bother everyone — your family, your neighbours, your guests. A good dimming system is essential. With app-controlled systems, adjusting brightness takes seconds.
Mistake 3 — Poor placement. Not every home is the same. The position of your windows and doors, the colour of your walls, and your roofline all affect how the light behaves. Light walls reflect; dark walls absorb. Dormers and angles create challenges. This is where professional experience pays off — we’ve seen every type of home and know how to plan around the details that most people overlook.
How Much Will You Actually Save?
Refernce: Hydro Quebec
Here’s a concrete example. Say you have 10 soffit lights running 4 hours every evening.
With traditional 50-watt bulbs: 10 × 50W × 4 hours × 365 days × $0.15/kWh = about $110 per year.
With LED soffit lights at 7 watts each: 10 × 7W × 4 hours × 365 days × $0.15/kWh = about $16 per year.
That’s a saving of nearly $95 every year — just on electricity. If your installation costs $200, you recover the investment in just over two years. After that, every dollar saved stays in your pocket. And since LEDs last 25 times longer than standard bulbs, you’re also eliminating the cost and hassle of replacements for years to come.
Smart Features Worth Knowing About
Today’s permanent LED soffit lights go far beyond a simple on/off switch.
Seasonal colours let you switch to orange and purple for Halloween, red and green for Christmas, or red and white for Canada Day. You can change the whole look of your home in seconds, right from your phone.
Automated scheduling means your lights turn on at sunset, dim later in the evening, and shut off overnight — without you lifting a finger.
Smart home compatibility. Gemstone Lights integrates with Google Home, Amazon Alexa, and Control4. Control your lights by voice, create routines, and tie them into your existing smart home setup.
Music sync. Some systems can pulse in time with music. It’s a feature that turns a summer gathering into something memorable.
Permits: What You Need to Know in Quebec
For single-family homes, permanent LED soffit lights are plug-and-play. They run on a standard 115-volt outlet. No electrical panel work is required and no permit is needed. It’s a project most homeowners can complete in a weekend.
For multi-unit and commercial buildings — duplexes, triplexes, apartment buildings, offices, and commercial spaces — the rules are different. Even though the system runs on 115 volts, Quebec’s Régie du bâtiment du Québec (RBQ) requires a specialized permit and a certified installer for this building category. Always ask your contractor for their RBQ licence number, proof of liability insurance, and references from similar projects before signing anything.
A Better Choice for the Environment Too
By switching to permanent LED soffit lights, you’re doing more than saving money. LEDs use up to 90% less energy, which reduces pressure on the electrical grid and lowers CO2 emissions. Because they last 25 times longer, far fewer bulbs end up in landfills. And by working with a local Montreal company like Éclairage Extérieur Montréal, you’re supporting the local economy and reducing the environmental footprint that comes with international shipping.
