Lighting is one of the most impactful changes you can make to a home — and one of the most misunderstood from an electrical standpoint. Swapping a light fixture sounds simple until you discover the junction box does not support the weight of a ceiling fan, the existing wiring does not accommodate a dimmer, or the circuit is already loaded to capacity from the fixtures already on it.
CMC Electric handles every type of indoor lighting project across Raleigh, Clayton, and the greater Triangle area — from single ceiling fan installs and under-cabinet kitchen lighting to whole-home LED retrofits, recessed lighting layouts, and smart dimmer and control system wiring. Our licensed electricians focus on getting the electrical side right so that your lighting looks the way you want it to and works safely for years.

Licensed electricians in the Raleigh area install ceiling fans and interior light fixtures as one of the most common residential electrical services. While hanging a simple fixture on an existing junction box may seem straightforward, there are electrical and structural considerations that make professional installation the safer and more reliable path — especially for ceiling fans, heavy chandeliers, and fixtures being installed in locations where no junction box currently exists.
For ceiling fans specifically, the junction box in the ceiling must be rated to support the weight and vibration of a fan. A standard light fixture box is not sufficient. If the existing box is not fan-rated, the electrician will replace it with one that is properly braced to the ceiling framing before the fan is mounted. The wiring also needs to support the fan’s motor and, if applicable, an integrated light kit — which may require a dedicated switch or a fan-and-light wall control.
CMC Electric installs ceiling fans, chandeliers, pendant lights, flush mounts, recessed lighting, and every other type of interior fixture. We verify the junction box rating, confirm the circuit capacity, install any needed switches or controls, and test everything before we leave. If you are replacing an existing fixture with something similar, the install is usually quick. If you are adding a fixture where there is no existing wiring — such as adding recessed lights to a room that only has a single center fixture — the scope is larger, but our technicians handle the wiring, box installation, and switch work as a complete package.
Under-cabinet lighting illuminates your kitchen countertops from beneath the upper cabinets, eliminating the shadows that overhead ceiling fixtures create when you are working at the counter. It is one of the most popular kitchen lighting upgrades in the Raleigh area because it makes a significant visual and functional difference at a relatively modest cost.
There are two main installation approaches: plug-in and hardwired. Plug-in under-cabinet lights connect to a nearby outlet and typically include a visible cord running from the light strip down to the receptacle. This is the simpler option and does not require an electrician, but the cord is visible and the lights are limited to locations near an existing outlet.
Hardwired under-cabinet lighting is connected directly to a circuit inside the wall, with a dedicated switch that controls all the lights together. There are no visible cords, the switch is flush-mounted on the wall or backsplash, and the result looks clean and permanent. Most LED under-cabinet systems draw very little power, so adding them to an existing kitchen circuit is usually possible without overloading anything.
CMC Electric installs hardwired under-cabinet lighting as part of kitchen remodels and as a standalone upgrade. We run the wiring inside the wall, mount the LED strips or puck lights beneath the cabinets, install a wall switch in a location that makes sense for your kitchen layout, and test the circuit. If you already have plug-in under-cabinet lights and want to upgrade to a hardwired setup, we can convert the installation and remove the visible cord in the same visit.
An LED retrofit replaces older incandescent, halogen, or fluorescent lighting with modern LED fixtures or LED-compatible components. The term “retrofit” applies both to replacing entire fixtures and to swapping out the bulbs or modules inside existing fixtures — depending on the fixture type and condition.
The benefits are meaningful. LED lighting uses significantly less electricity than incandescent or halogen equivalents — typically 75 to 80 percent less for the same light output. LEDs also last far longer, often 25,000 hours or more compared to roughly 1,000 hours for a standard incandescent bulb. That translates into lower energy bills and far fewer bulb replacements over time. The light quality has also improved dramatically in recent years — modern LEDs are available in warm, neutral, and cool color temperatures that match or exceed the feel of the older bulb types they replace.
For homes with recessed can lights, an LED retrofit often involves replacing the old housing trim with an integrated LED module that snaps into the existing can. For fluorescent fixtures — common in kitchens, garages, and utility rooms built in the 1980s and 1990s — the retrofit may involve replacing the entire fixture with an LED panel or strip fixture.
CMC Electric performs LED retrofits for homes and businesses across the Raleigh and Triangle area. We assess your existing fixtures, recommend the best retrofit approach for each location, handle any wiring or compatibility issues (such as dimmer switches that are not LED-compatible), and install everything in a single visit for most residential projects.
Yes. While interior designers and dedicated lighting designers are one option, many homeowners prefer to work directly with their electrician for practical lighting layout guidance — especially when the project involves new construction wiring, a remodel rough-in, or adding recessed lighting to an existing room.
A lighting layout consultation covers how many fixtures a room needs based on its square footage and ceiling height, where to place them for even coverage without dark spots or glare, what fixture types are best suited to the space (recessed cans, flush mounts, pendants, track lighting), what color temperature will feel right for the room’s purpose, and where switches and dimmers should be located for convenient control.
CMC Electric provides lighting layout guidance as part of our indoor lighting installation service. When you are adding recessed lighting to a living room, planning the lighting for a kitchen remodel, or upgrading an entire floor of your home, our technicians will walk the space with you, discuss your goals, and recommend a fixture count, placement, and control plan before any wiring begins. This is not a separate billable design service — it is how we approach every lighting project, because getting the layout right before cutting into the ceiling avoids costly rework and ensures you are happy with the result.
For larger or more complex projects — such as a whole-home lighting plan for new construction — we can collaborate with your builder, designer, or architect to ensure the electrical rough-in matches the design intent.
Lighting control systems range from simple dimmer switches to whole-home automated systems that let you control every fixture from a wall panel, a phone app, or a voice assistant. The right level of control depends on your goals and budget, and most of these systems require professional electrical installation.
At the simplest level, a dimmer switch replaces a standard toggle or rocker switch and allows you to adjust the brightness of the fixture it controls. Installing a dimmer involves more than just swapping the device — the electrician needs to confirm the dimmer is compatible with the fixture type (LED fixtures require LED-rated dimmers, and not all combinations work well together), verify the wiring supports the dimmer configuration, and ensure the dimmer is rated for the total wattage on the circuit.
At the more advanced end, systems from manufacturers like Lutron and Crestron provide centralized lighting control for entire homes or commercial spaces. These systems use dedicated dimmers, keypads, and a central processor that allows preset lighting scenes, scheduling, occupancy-based automation, and integration with shading, audio, and other smart home platforms. Installation involves specialized wiring, programming, and commissioning that goes well beyond a standard switch swap.
CMC Electric installs dimmer switches, smart switches, and lighting control wiring for homes across Raleigh and the Triangle. For basic dimmer upgrades, we handle the installation and compatibility check during a standard service visit. For more advanced control systems, we work with homeowners and integrators to ensure the electrical infrastructure — dedicated circuits, low-voltage wiring, neutral wires at switch locations — is in place to support the system.
The answer depends on the scope of the work. Replacing an existing light fixture with a new one on the same junction box — a straight swap — typically does not require a permit because you are not modifying the wiring or adding a new circuit. This is true for most simple fixture replacements across Raleigh and Wake County.
Adding new recessed lights, running new wiring to a location that does not currently have a fixture, or adding a new circuit to support additional lighting does generally require an electrical permit. The permit ensures the new wiring and connections are inspected for code compliance — proper box installation, correct wire gauge, appropriate circuit protection, and safe installation practices.
The threshold can feel ambiguous, and it varies slightly between the City of Raleigh, Wake County, and the smaller municipalities in the Triangle. As a general rule, if new wiring is being pulled through walls or ceilings, a permit is likely required.
CMC Electric handles the permitting question for you on every job. During the initial consultation, we assess the scope, determine whether a permit is needed, and if it is, we submit the application, complete the work, and schedule the inspection. You never have to make the permit determination yourself or worry about whether the work was done to code — that is our responsibility from start to finish.
Technically, a homeowner can replace a light fixture with a ceiling fan in their own primary residence in North Carolina. But there are important reasons most homeowners choose to hire a licensed electrician for this particular swap.
The biggest concern is the junction box. A ceiling fan is heavier than most light fixtures and introduces sustained vibration from the motor. If the existing junction box is only rated for a light fixture — which is common — it will not safely support a fan. The box needs to be replaced with a fan-rated brace box that is anchored to the ceiling joists. Getting to the existing box typically means working in the attic or through the ceiling opening, and installing the brace correctly requires reaching the framing on both sides of the box location.
The wiring also matters. A basic light fixture switch turns the fixture on and off. A ceiling fan often benefits from separate fan and light controls — either two wall switches or a combination fan control device — which may require pulling an additional wire from the switch box to the ceiling box. If that additional wire is not present and you do not want to use a remote-control-only solution, new wiring needs to be run.
CMC Electric handles ceiling fan installations regularly and can assess the junction box, upgrade it if needed, run additional switch wiring, and install the fan and any wall controls in a single visit. We confirm everything is secure, balanced, and properly controlled before we leave.
Recessed lighting — also called can lights or downlights — is one of the most versatile and popular fixture types for homes in the Raleigh area. The fixtures sit flush with (or slightly above) the ceiling surface, creating clean lines and even illumination without a visible fixture hanging below the ceiling plane.
There are a few key decisions involved in choosing recessed lighting. The first is housing type. New construction housings are designed to be installed before the ceiling drywall goes up. Remodel housings are designed to be retrofitted into an existing finished ceiling — they clip to the drywall from above and do not require access to the ceiling joists. If your home is already finished and you are adding recessed lights, remodel housings are what your electrician will use.
The second decision is size. The most common residential sizes are four-inch and six-inch diameter. Six-inch is the traditional standard for general room lighting. Four-inch provides a more subtle, modern look and works well for accent lighting or smaller spaces.
Third is trim and light type. Most new recessed installations today use integrated LED modules rather than separate bulb-and-trim combinations. Integrated LED trims are energy efficient, produce consistent light quality, and are available in a wide range of color temperatures — from warm (2700K) to daylight (5000K).
Finally, if the lights will be on a dimmer — which is common for living rooms, bedrooms, and dining areas — the LED module and the dimmer switch need to be compatible. CMC Electric handles the selection and compatibility check as part of every recessed lighting project and can recommend specific products based on your preferences and the room’s purpose.
The cost of adding recessed lighting depends on several factors: how many fixtures you want, whether the room has accessible attic space above it, how far the fixtures are from the nearest power source, and whether new switch wiring or a dimmer is included.
For a room with attic access above the ceiling — which makes running wire and positioning housings significantly easier — a standard installation of four to six recessed LED lights with a dimmer switch is a common residential project. The cost increases when the room is on a lower floor with a finished room above it, because the electrician has to work through small ceiling openings and fish wire through enclosed joist bays without the benefit of open attic access.
Other factors that affect cost include whether the project requires a new circuit (if the existing circuit is already fully loaded), whether the ceiling is insulated (which requires IC-rated housings that are safe to be in direct contact with insulation), and whether the fixtures are being integrated into a lighting control or smart home system.
CMC Electric provides a written estimate for every recessed lighting project before any work begins. We assess the room, discuss layout and fixture count, check the ceiling access and circuit capacity, and give you a clear number that includes fixtures, wiring, switches, permits (if required), and labor. There are no hidden charges and no surprises on the final invoice.
