The best permanent Christmas lights are judged on six things, and brand isn’t one of them: an even warm white along the whole run, housings and connectors sealed for year-round weather, a track that matches your trim, the right pick between addressable and single-color, control you own, and a written warranty from someone who can service it.
If you want the brands side by side, our permanent lighting page covers how the major permanent lighting systems compare. Picking the best permanent Christmas lights for your house is a different job, and this is the checklist for it. And if you’re a step earlier than that, still working out what a permanent Christmas light system actually is or whether permanent lights are worth it for your house, those two posts come first.
Start with the white light
Color is what the demo videos show. White is what you’ll be looking at on an ordinary night in March if the lights run year-round, and it’s where a cheaper system tends to give itself away.
Ask two things. The first is color temperature. Every landscape lighting system we design runs 2700–3000K, a warm white close to the old incandescent glow, and our notes on choosing color temperature and fixture material explain why we hold that line. A roofline that sits in the same warm range looks at home above that kind of garden lighting. A cold, bluish white doesn’t.
The second is consistency. When two LEDs on the same eave read as slightly different whites, it often points to mixed production batches or lower-grade chips. No spec sheet will show you this. Ask to see a lit run, at dusk if you can, and look along it from the street rather than standing underneath.
Weather sealing and what fails first
On the landscape systems we repair, the faults we see most are failed transformers, corroded connections, cut cable, water ingress and fixtures at end of life. Count how much of that list comes down to joints and water. A roofline system is built differently, but it lives in the same climate: months of Middle Tennessee humidity, then freeze-thaw cycles through the winter, and both are hard on any coating or seal that was only designed for occasional outdoor use.
The LEDs are usually the tougher half. Permanent LEDs are rated for 25,000 to 50,000 hours, so on a decent system it’s the housings, the connectors and the points where cable enters them that give out first. So ask for the rating on those parts, not just the LED strip. Housings and connectors are normally rated with an IP code. The second digit of that code covers protection against water, and a higher digit means more protection.
Then ask what happens when a joint does fail, because eventually one will. When we repair a system, a failed joint is re-made with a properly rated waterproof connector instead of being patched, and an installer should be able to tell you plainly how they handle it.
Track material and matching your trim
The track or channel holding the LEDs is on your fascia every day of the year, lit or not. Three questions cover it. Can the track be painted, or does it come in a fixed finish that can’t be changed without damaging it? If it’s fixed, how close do the available colors get to your trim? And will the finish stand up to direct sun without chalking, fading or warping? A track that matches the trim all but disappears by day. One that doesn’t reads as a stripe along the roofline, and that’s hardest to live with on a house where the lighting is supposed to look as though it was always part of the architecture.
Addressable or single-color
Single-color systems run one white, sometimes with a second fixed option. Addressable systems let each LED, or each small group of LEDs, be set on its own, which is what makes color changes, chases and holiday patterns possible. That ability is carried by the controller and its software, so more of the system depends on electronics doing their job.
Single-color has fewer electronic parts to fail. It suits a house where the goal is a clean, warm line along the roof for most of the year, with Christmas as a bonus. If the color shows are the reason you’re buying, addressable is the only way to get them, and the controller questions below matter even more.
Either way, permanent systems are generally priced by the installed foot. As a national market benchmark that’s roughly $25 to $35 per linear foot, or around $3,000 to $12,000+ for a whole-home system. There’s more on what permanent outdoor lighting costs on our pricing page.
Who owns the controller and the app
Find out who holds the app account, you or the installer. Ask whether the system needs a subscription to keep working and what happens if it lapses. Then ask whether the lights can still be switched on and off, even by hand, if the app stops being supported or the company behind it closes. A system that only answers to one company’s login is a dependency you’re buying along with the lights.
The warranty and who can service it
Get the warranty in writing before anything goes on the roof. It should say what’s covered (parts, workmanship or both) and for how long. Our own workmanship warranty covers the installation itself, meaning the wiring, connections, fixture mounting and transformer programming. Full terms and duration are something to confirm with Phil during the design walk. On the final walkthrough of an install, Phil tests every circuit and adjusts anything that isn’t exactly right, and it’s worth asking any installer whether someone does that before the crew leaves.
Then there’s serviceability. Gemmell Outdoor Lighting is not a Trimlight dealer or a JellyFish dealer, and we service any brand, including Trimlight, JellyFish and Gemstone systems installed by others. Put the same question to anyone you’re considering: if they stop carrying your brand, or close, who else can work on this system? If the honest answer is “only us,” weigh that before you sign. Our lighting maintenance and repair service is the part of the business that picks this up once a system is in place. Expect any repair, from us or anyone else, to be quoted after the system is tested, since the fault has to be found before fixing it can be priced.
Common questions
Are addressable RGB lights better than single-color permanent lights?
Not better, just built for a different job. Addressable systems can change color and run patterns, which depends on a controller and app that have to keep working. If the goal is a warm architectural line along the roof for most of the year, single-color is the simpler choice with fewer parts to fail.
If holiday color shows are the reason you’re buying, addressable is the only way to get them.
What weather rating should permanent lights have?
Ask for the rating on the housings and connectors, not only the LED strip. Those parts are normally rated with an IP code, where the second digit describes protection against water and a higher digit means more protection. The LEDs, rated for 25,000 to 50,000 hours, usually outlast the seals.
Middle Tennessee humidity and freeze-thaw cycles are hard on any seal, and on the landscape systems we repair, water ingress and corroded connections are among the faults we see most.
Can permanent light track be painted to match my trim?
Some can and some can’t. Certain tracks can be painted to match the trim, while others come in a fixed finish that can’t be changed without damaging it. Ask before you buy, and ask how the finish handles direct sun. A matched track all but disappears into the fascia by day.
A mismatched one reads as a stripe along the roofline whether the lights are on or off.
Do cheaper permanent lights fade or shift color over time?
They can. Rated life and color stability are separate specs. Permanent LEDs are rated for 25,000 to 50,000 hours, but that figure is about how long the LEDs last, and it says nothing about whether their white stays the same shade over those years. Lower-grade chips are more prone to drifting, which shows up as mismatched whites along one run.
Ask the installer how the system holds its color and whether the warranty covers it.
