Permanent Christmas Lights: Never Hang Lights Again.

Permanent outdoor lighting is the single highest-ROI upgrade available to a Williamson County home. One professional installation. Zero seasonal hassle. Every holiday, game day, or quiet evening — exactly the light you want, from the fixtures already built into your roofline and eaves.

Permanent Christmas lights are what most people call this, and that is a fair place to start, because the roofline run that does December is the same run that does game day in October and a quiet warm white the rest of the year.

Permanent outdoor lighting means professionally installed fixtures that stay up year-round, tucked into the eave or clipped along the roofline and run from an app. Warm white on a Tuesday evening, red and blue for the Fourth of July, off entirely when you want the house dark. The LEDs themselves are rated for 25,000–50,000 hours and draw 70–80% less power than the halogen systems they replaced. Gemmell Outdoor Lighting specs 2700–3000K warm white and nothing higher on residential work — the cold blue cast has no place on a home.

The alternative is the routine most people already know: drag the ladder out every November, fight the extension cords, then jam a tangled bin back in the garage until next year. A permanent system ends that. One install, and the ladder stays in the shed for good.

Permanent Lighting Prices

What the Brands Actually Cost

Most people land here after pricing a name brand — Trimlight, JellyFish, Gemstone, Oelo — and finding that no two quotes agree. Here is the honest market picture, drawn from published cost guides and dealer pricing rather than any single sales pitch, so you can read your own quote with clear eyes.

The permanent-lighting brands sell through dealer networks, and the number on your quote is set by two things above all: how much linear footage your roofline carries, and which brand's proprietary track and controller you're locked into. As of July 2026, national cost guides such as Angi and HomeAdvisor put a professionally installed permanent-lighting system in the range of roughly $2,000 to $6,000 for a typical home across the market, and above $10,000 once you wrap a large or multi-story property — figures that track closely with the whole-home range independent installers quote around Nashville. The brand you choose moves that number less than the size of your home and the quality of the components do.

What the brand does lock in is everything after the sale. A franchise system ties you to that brand's track profile, its controller, its app, and — critically — the dealer who installed it. An independent, design-first install like Gemmell Outdoor Lighting's carries no such lock-in: we spec the component to the architecture, and we service the result ourselves. If you want the full local pricing picture beyond the brand names, our outdoor lighting cost guide for Nashville walks through what actually moves a quote here.

Trimlight, JellyFish, Gemstone & Oelo — the Real Cost Picture

Trimlight is the most-searched name in Middle Tennessee, and Trimlight dealer quotes around Nashville typically run in the low four figures for a roofline-only home and climb into the five figures on larger properties — with the exact number set at a free in-home measure rather than published up front. Because dealers price by the linear foot, some permanent-lighting companies now publish a per-foot rate to set expectations: one Nashville-area installer lists roughly $28 per linear foot, a useful market-rate yardstick for reading any brand's quote against your own roofline.

JellyFish Lighting sits at the premium end of the field. National cost guides put JellyFish installs in the same broad band as the category — a few thousand dollars for a modest home into five figures for a large one — with the premium justified by its addressable-pixel control and pixel-mapped effects. Gemstone Lights runs a comparable franchise-and-dealer model to Trimlight, so its pricing lands in the same neighborhood and is likewise quoted per property rather than posted publicly. Oelo is a Colorado-made system sold through certified dealers; it competes on fixture quality and warranty rather than on being the cheapest bid, and like the others it is priced on a per-home basis. Across all four, the honest takeaway is the same: the brand name on the box explains far less of your final price than your linear footage, your fixture grade, and whoever ends up on the hook to service it.

Why Is Trimlight So Expensive?

It usually isn't the LEDs — it's the model. A franchise system carries the brand's licensing, the dealer's overhead, and a proprietary track-and-controller platform that only that brand's app and that brand's dealer can service. You are paying for the network as much as the light.

That is the exact wedge for a design-first independent: Gemmell Outdoor Lighting designs the system to your home first and then specs the fixture that fits the architecture, so your money goes into component quality and a clean install rather than into a franchise fee and a lock-in you can't service yourself. For homes inside a covenant community, it's also worth reading the outdoor lighting rules for Williamson County and, if your neighborhood values a dark night sky, our guide to dark-sky-friendly outdoor lighting around Nashville before you sign anything. If you'd rather talk it through in person, we serve Brentwood and the surrounding Williamson County communities, and the design walk is free.

Frequently Asked Questions

Common questions about permanent outdoor lighting in Williamson County.

Is permanent outdoor lighting the same as Trimlight or Jellyfish?

Trimlight and Jellyfish are popular brand-specific franchise systems. Permanent outdoor lighting is the category — Gemmell Outdoor Lighting designs and installs permanent fixtures that aren't tied to any single brand. We choose the right components for your specific home, and we service any brand including Trimlight and Jellyfish systems installed by others.

How is permanent lighting different from putting up Christmas lights every year?

Permanent fixtures are professionally designed into your roofline and eaves once. No ladders every November, no storage, no damaged gutters. The same fixtures handle every occasion year-round — holidays, game days, or simply a warm white every evening. Over two to three holiday seasons, the cost of annual installations typically exceeds the permanent install.

What happens if a fixture fails or I want to change the design?

Gemmell Outdoor Lighting services every system we install. If a fixture fails, you call us — not a brand hotline. If you want to change colours, add zones, or integrate the system with new landscape lighting, the same team comes back. We also repair permanent lighting systems installed by other contractors.

Can permanent lighting work with my existing landscape lighting system?

Yes — and designing them together is where the result looks genuinely different. When your permanent roofline fixtures and your landscape lighting are designed as a single system, the color temperatures match, the zones complement each other, and you control everything from one place.

Gemmell Outdoor Lighting designs both, which is the advantage over brand-franchise installers who only handle one layer.

Do you install Trimlight in Nashville / Williamson County?

Gemmell Outdoor Lighting is an independent outdoor lighting design company, not a Trimlight dealer. We install commercial-grade permanent lighting systems custom-designed for your home. We also service and repair Trimlight systems installed by others. If you've been quoted by a Trimlight dealer and want a second opinion, we're happy to walk your property.

How long does a permanent lighting installation take?

Most roofline-only installs are completed in one day. Full property systems with landscape integration typically take one to two days. Phil will give you a precise timeline in your written quote before any work begins.

What's the difference between Trimlight, JellyFish, and Gemstone?

All three are permanent-lighting brands sold through dealer networks. Trimlight and Gemstone use a similar channel-based track with a brand app; JellyFish leans on addressable-pixel control for pixel-mapped effects and sits at the premium end. The practical difference for a buyer is less about the light and more about who services it.

Each is tied to its own dealer, app, and proprietary track. Gemmell Outdoor Lighting is independent — we spec the fixture that fits your home rather than the one a franchise assigns us, and we service any brand, including Trimlight, JellyFish, and Gemstone systems installed by others.

How much does permanent lighting cost around Nashville?

As of July 2026, national cost guides such as Angi and HomeAdvisor put the market range for a professionally installed permanent-lighting system at roughly $2,000 to $6,000 for a typical home, rising above $10,000 for large or multi-story properties — and Nashville-area quotes track closely with that.

Because dealers price by the linear foot, one Nashville-area installer publishes roughly $28 per linear foot as a benchmark. Your own number is driven by your roofline footage and fixture grade, not the brand name; Gemmell Outdoor Lighting gives you a written quote after a free design walk.

Is Trimlight or JellyFish cheaper?

JellyFish generally sits at the premium end of the field for its addressable-pixel control, while Trimlight and Gemstone tend to land in a similar band as each other — but published cost guides show every brand's range overlaps heavily, because home size and linear footage move the price far more than the badge does.

Rather than chase the cheaper brand, it's worth comparing quotes on the same footage and asking who is contractually responsible for service afterward. An independent, design-first install carries no franchise lock-in and is serviced by the same team that designed it.

Where do you install permanent outdoor lighting?

Across Williamson County and the Davidson County estate corridor: Franklin, Brentwood, Belle Meade, Leipers Fork, Thompson Station, Fairview, Nolensville, Spring Hill, Green Hills, Forest Hills, Oak Hill, and Hendersonville. Each of those towns has its own permanent lighting page with the local approval notes. If you are within about thirty minutes of Franklin, the answer is yes.

Can outdoor lighting increase home value?

Nobody can put a reliable percentage on it, and anyone who quotes you one is guessing. What it does reliably is change how the house presents after dark, which is when evening showings happen and when most listing photography now gets shot.

A finished-looking property at night is worth something to a buyer; it is not a line on an appraisal.
