Yes — adding permanent LED lighting to an existing pool cage is one of the most common retrofit jobs Brighter Nights installers handle nationwide. In most cases, a certified installer completes the entire job in a single day with no major construction: wire runs through the hollow aluminum extrusion channels, fixtures clip to the frame, and the transformer mounts near an existing exterior GFCI outlet.
After more than 20 years and over 2,000 installs across the country, I can tell you this with confidence: adding lighting to an existing pool cage is not a complicated project. It feels like it should be — you’re threading wire through an aluminum extrusion frame, coordinating with a licensed electrician, and working around a structure that wasn’t originally designed with lighting channels in mind. But the reality is that pool cage lighting has evolved specifically with retrofit installations in mind.
The aluminum extrusion frames used on the vast majority of pool cages and screen enclosures aren’t just structural — they’re hollow channels. Low-voltage wire runs through them cleanly, without additional conduit in most cases. Fixtures mount directly to the frame using purpose-built clips that don’t penetrate the screen or compromise the cage’s structural integrity. The low-voltage system (12V DC) means the installer isn’t running line voltage through or around the enclosure itself, which simplifies permitting, keeps the job cleaner, and reduces risk.
There’s a reason this is the job I’ve quoted more than any other: homeowners finish their pool cage, live in it for a few years, and then realize they want to actually use the space at night. The retrofit market is enormous, and the product was designed with that reality in mind.
Before any wire is cut or fixture is ordered, a qualified Brighter Nights installer runs through a site evaluation. Here’s what we’re looking at — and why each factor shapes the final design:
The first question isn’t “where do you want the lights?” — it’s “where’s your panel, and what capacity do you have available?” Permanent pool cage lighting runs on low voltage (12V), which requires a transformer. That transformer plugs into a standard 120V GFCI outlet, which needs to be within a reasonable distance of the planned transformer location.
In most Florida homes and throughout the Sun Belt, there’s already an exterior outlet on or near the pool deck — often installed for pool equipment or an existing landscape lighting system. If that outlet is accessible and properly rated, we can use it. If not, the installer will coordinate with a licensed electrician to add one. This is typically a modest add-on to the overall project scope, not a dealbreaker.
We also assess whether the existing electrical in the area is in good shape — not because we’re connecting to it directly, but because nearby older wiring can affect permit review and inspector expectations in some jurisdictions.
The transformer is the heart of a low-voltage lighting system. On a pool cage retrofit, transformer placement is both a technical and an aesthetic decision. It needs to be:
One of the most common mistakes on underpowered installs is undersizing the transformer for future expansion. A certified Brighter Nights installer designs to the full fixture count of the finished project, not the minimum viable load. This matters because voltage drop is real — if you run too many fixtures off an undersized transformer, the fixtures at the far ends of a run will be visibly dimmer. We prevent that at the design stage, not after the fact.
Not all pool cages are identical. Standard aluminum extrusion frames — the most common type in Florida and throughout the Southeast and Gulf Coast — are the easiest to work with. The hollow channels accommodate wire runs naturally, and we have purpose-built mounting hardware engineered for these frames.
Some enclosures use heavier structural aluminum, older birdcage-style framing, or frames that have been repaired or modified after hurricane damage. None of these are deal-breakers, but they affect wire routing strategy and sometimes fixture mounting approach. A wood-framed or composite-framed lanai structure requires a different approach — more similar to an eave installation than a cage installation.
We also assess the cage’s overall condition. A cage that’s overdue for rescreening or has compromised fasteners may need attention before or concurrent with the lighting install. Surfacing that conversation upfront is always better than discovering it when a fixture is already mounted. For a full breakdown of how fixtures attach across different cage types — and how IP ratings apply to the 12V fixtures used in wet and coastal environments — see our guide on pool cage lighting fixture types.
This one surprises homeowners more than anything else on the evaluation list. Many communities — particularly in Florida, Arizona, Texas, and the Carolinas — have HOA guidelines that govern outdoor lighting colors, brightness levels, and sometimes fixture visibility from the street. Before designing a full color-changing RGB system, a good installer asks: what does your HOA allow?
In most cases, the answer is “white, warm white, or subtle color accents that aren’t visible from the road.” That’s exactly what a well-designed pool cage lighting system delivers anyway — the fixtures face inward, the light is contained within the enclosure, and the overall effect is ambiance rather than spectacle. But if formal restrictions are in place, we want to design within them from day one, not retrofit the retrofit.
Local building codes vary by county and municipality. Some jurisdictions require a permit for any new electrical work, including low-voltage transformer installations. Others treat 12V systems as exempt. Your installer will know the requirements for your specific area and will manage permitting as part of the job scope.
Contractors new to permanent lighting sometimes ask whether they should spec lighting during a new cage build rather than coming back for a retrofit later. It’s a fair question, and the honest answer is: the difference is smaller than you’d expect.
In a new build, the main advantage is wire routing. If the cage is being assembled from scratch, an installer can position wire before the frame is fully closed, potentially simplifying a few runs in tight corners. In practice, however, most new cage builds don’t pre-plan for lighting — the cage builder and the lighting installer are usually different trades, and coordination between them adds complexity that often negates the time advantage.
In a retrofit, the frame is already standing, but it’s not a barrier — it’s a channel. Experienced installers route wire through aluminum extrusion with a fish tape or flexible probe, the same technique an electrician uses to fish wire through a finished wall cavity. The process takes slightly longer than working in an open structure, but the finished result is identical: wire inside the frame, fixtures mounted externally, no exposed cabling anywhere.
“I’ve done new builds and retrofits. Honestly, I often prefer retrofits — the cage is stable, I can see the finished space clearly, and the homeowner knows exactly what they’re getting. With a new build, we’re sometimes working from a blueprint and a conversation.”
— Austen Stucki, Founder & CEO, Brighter Nights Lighting Technologies
The takeaway: if you’re planning a new cage, a quick conversation with a lighting installer during the planning phase is worthwhile. But if you already have a cage and you’re ready for lighting, don’t hold off waiting for a future project. The retrofit is the standard path, and the system is optimized for it.
Let me walk you through what a standard retrofit looks like, using a composite of projects from our Florida market — the kind of job that takes one installer and one assistant about six to eight hours from truck arrival to final walkthrough.
The property: A 1,400 square foot screened pool cage on a single-story home in a Central Florida development. Standard aluminum extrusion frame with 10-foot knee walls and a peak of about 14 feet. One existing exterior GFCI outlet on the back of the house, approximately 15 feet from the planned transformer location. No prior landscape or architectural lighting anywhere on the property.
Before the install: After dark, the pool area is completely dark beyond the glow of the underwater pool light. The homeowners rely on a string-light setup they clip to the cage frame each season and remove before storms. The HOA has mentioned the temporary lights twice. They use the pool maybe once a week in the evenings — the dark and the seasonal takedown hassle work against it.
The design: Thirty-two IP68-rated 12V LED fixtures along the main horizontal rafter lines, positioned to wash the pool deck with even light. Four additional fixtures at each corner post to eliminate shadows. One 300W transformer — sized for up to 40 fixtures with room to add a zone later — mounted on the exterior wall under the home’s soffit, connected to the existing GFCI outlet.
After the install: The enclosure is fully and evenly lit from within. Shadows are gone. The family now uses the pool four to five evenings a week during fall and spring. The system runs on a timer — on at dusk, off at 10:30 PM — and the controller lives in their smartphone app. Neighbors have asked who did the work. The HOA said nothing, because from the street, you see only a softly lit pool cage that looks like it was always meant to be that way.
That’s a representative outcome, not a cherry-picked example. For context on what projects like this cost across different cage sizes and fixture counts, see our complete pool cage lighting cost guide.
For a straightforward pool cage retrofit — existing outlet accessible, standard aluminum frame in good condition, design finalized before install day — expect the following timelines:
These timelines assume a two-person crew, which is standard for most certified Brighter Nights installers. A solo installer can complete the work, but certain wire-fishing steps genuinely benefit from one person at each end of the run.
Factors that extend install time include:
Your installer will give you a project-specific timeline during the site evaluation. If you haven’t had an evaluation yet, start with a free design estimate — it asks the right questions to give you a realistic scope before anyone shows up at your property.
Here’s how a typical installation day unfolds, so there are no surprises when the crew arrives:
You don’t need to be present for every phase — most homeowners check in at the start and again at the end. But plan to be available for the final walkthrough, because that’s when you review and approve the finished system before the crew leaves your property.

I want to address a concern I hear from homeowners who’ve done some initial research: “I’ve read that running wire through screen enclosures is complicated. Is my project actually going to be a standard job, or will it be a special case?”
It’s a standard job. Pool cage retrofits represent a significant share of our nationwide install volume. Our certified installers train specifically on pool cage and lanai applications — it’s a core module in the Brighter Nights Installer Academy, covering everything from frame-specific wire routing techniques to local permit environments across different states. The tools, hardware, and procedures are purpose-built for this application.
What makes it feel complicated to homeowners is that it looks invisible when done correctly. You don’t see the wire. You don’t see the mounting hardware. You see fixtures that appear to float on the frame, and a transformer sitting discreetly on an exterior wall. That “how did they do that?” reaction is exactly the result we’re designing for.
If you’re looking for a certified installer in your area, the Brighter Nights distributor and installer network covers the country — use the locator to find a trained professional familiar with your cage type and local permitting environment.
