Interior Lighting Design & Installation in Dallas–Fort Worth
The same eye applied indoors — and the same license. Interior design, installation and LED conversion, usually alongside the outdoor work.
What This Actually Involves
Interior lighting is not a separate trade so much as the same problem indoors: what is worth lighting, from where, and at what level. The instincts that make a live oak read properly at night are the instincts that keep a kitchen from being flat or a hallway from being a tunnel.
Most of our interior work comes from clients who already have us outside — it is straightforward to handle both while we are on site, and it means the view out of a window at night is designed as one picture rather than two. TC Lighting is a licensed Texas Electrical Contractor, which is what lets us do line-voltage interior work rather than just swapping lamps.
Our photography to date is all exterior work.
Interior Lighting — The Detail
What a Lighting Contractor Does Indoors
Interior work here is specific rather than general. It is not a whole-house electrical remodel and it is not a decorating service. It is the lighting a room needs to work properly after dark, installed by an electrical contractor who has spent forty years thinking about how light lands on a surface.
In practice that means under-cabinet and task lighting in kitchens, cove and indirect lighting, toe-kick and stair lighting, lighting for display cases, shelving, art and architectural detail, closets and pantries, and LED conversion of interior fixtures that are still running old lamps.
The through-line with the outdoor work is the same discipline: light the surface, not the eye. Almost every complaint about a room's lighting — it feels harsh, it is hard to work in, it makes people look tired — traces back to a bare source in the field of view or a single central fixture trying to do every job at once.
The Work That Makes the Most Difference
Under-cabinet lighting
The highest-return interior lighting there is, because a kitchen worktop is a genuine task surface that overhead lighting always shadows — you stand between the ceiling fixture and the counter, so you chop in your own shadow. Under-cabinet lighting fixes it, and the details decide whether it looks built-in or stuck on: the fixture set forward, toward the front edge of the cabinet rather than against the wall, so the light falls across the whole worktop instead of down the backsplash; a lens or diffuser so the reflection in a polished granite or quartz surface is a soft band rather than a row of dots; and the wiring concealed.
Cove and indirect lighting
Light thrown up into a cove or along a ceiling detail and bounced back down. It produces a soft, sourceless ambient light that flatters a room and a ceiling both. It is also unforgiving of a poor installation: a run that is too close to the ceiling face gives hot stripes instead of a wash, and any gap in the run reads as a shadow band.
Toe-kick and stair lighting
Low-level light that lets someone cross a kitchen or a landing at night without turning on a ceiling fixture and waking themselves fully up. On stairs it is a safety feature that happens to look expensive.
Display, shelving and art
Here colour rendering matters more than anywhere else in the house. A high-CRI source — 90 and above — shows the actual colours in a painting, a rug or a bottle. A cheap low-CRI lamp makes reds go flat and skin tones go grey, and people notice the effect without identifying the cause.
Tape Light, Done Properly
Most modern interior accent lighting is LED tape, and the gap between tape installed properly and tape stuck to a surface is enormous.
| Decision | Why it shows |
|---|---|
| Aluminium channel | Gives a straight line on an imperfect surface, sinks heat away from the diodes, and protects the tape. Bare adhesive tape sags and lifts eventually, especially warm. |
| Diffuser lens | Turns a row of visible diodes into a continuous line of light. This single component is the difference between "built in" and "strip light". |
| Diode density | Closely spaced diodes read as a line; sparse ones read as dots, and the dots are doubled in any polished surface below. |
| Colour rendering | CRI 90+ in kitchens, over art and anywhere people or food are seen. |
| Driver sizing and siting | Sized with headroom, placed where it can be reached and replaced without dismantling a cabinet, and kept out of a sealed hot pocket. |
Dimming is where interior LED work usually goes wrong
The single most common complaint about new LED lighting is that it flickers, buzzes, drops out at the bottom of the dimmer's travel, or will not go as low as expected. That is almost never the tape's fault. It is a compatibility problem between the dimmer and the driver — a legacy dimmer designed for a resistive incandescent load, being asked to control an electronic driver with a minimum load it never reaches.
Getting it right means choosing the dimmer and the driver as a pair, checking the minimum load against what is actually on the circuit, and knowing which dimming method the driver is built for. This is exactly the kind of detail an electrical contractor is supposed to handle and a general handyman is not.
One colour temperature per space, at least
Recessed cans at one white, under-cabinet at another and a pendant at a third is a common state of affairs in a kitchen that has been worked on by three people over ten years, and it looks exactly as unresolved as it sounds. Interior work should start by deciding what white the room is, and then making everything agree with it.
The Window Is the Part People Forget
Most of our interior work runs alongside an exterior project, and there is a good reason for the pairing that has nothing to do with convenience.
After dark, a window is either a picture or a mirror. If the room inside is lit and the garden outside is dark, the glass goes black and reflective, and every window in the back of the house becomes a mirror showing you your own kitchen. Light the garden and the glass turns transparent again: the room gains the depth of everything beyond it, and a house with a lit canopy at the end of the lawn feels substantially larger from the sofa than the same house with a black wall of glass.
Getting that right is a balance rather than a switch. Interior levels that are too high will always win against the exterior, which is one of the practical arguments for dimming inside: the evening setting that makes a room comfortable is also the setting that lets the garden through. It is why, when both are in scope, the interior and exterior lighting get designed as one picture rather than as two jobs that happen to share a wall.
Commercial interiors
The same work applies in a commercial setting — display and shelf lighting in a retail space, task lighting where people actually work, accent lighting on a reception wall or a feature, and LED conversion of interior fixtures still running old lamps and still costing money to run. TC Lighting works residential and commercial, and on the commercial side the licence is the entry requirement rather than a distinction.
Across Five Counties, From Carrollton
Whether you're in a 1930s University Park house, a new build in Frisco, or a commercial interior in Las Colinas, interior work is line voltage and needs a licensed contractor. Most of ours runs alongside an exterior project, so the view through the glass at night is designed as one picture.
Frequently Asked Questions
Yes. TC Lighting is a licensed Texas Electrical Contractor, TECL 41495, which covers line-voltage interior work rather than just swapping lamps. Most of our interior projects run alongside an exterior one.
Because at night they are one picture. What you see through a window is the interior lighting and the landscape lighting together, and designing them separately is how you end up with a bright room reflecting in the glass and nothing visible beyond it.
Yes, including fixtures and lamps that were never designed for it. Lower draw, far longer life, and a steadier colour than what it replaces.
Yes, offices and retail interiors as well as homes.
It is nearly always a compatibility problem between the dimmer and the LED driver rather than a fault in the lights. A legacy dimmer built for a resistive incandescent load is being asked to control an electronic driver, often with a minimum load the circuit never reaches. The fix is to select the dimmer and driver as a matched pair, check the minimum load against what is actually on the circuit, and use the dimming method the driver is designed for.
Under-cabinet lighting in a kitchen, by a distance. A worktop is a real task surface, and an overhead fixture always puts you between the light and the counter, so you work in your own shadow. Setting the fixture forward toward the front edge of the cabinet, with a diffuser so a polished stone surface reflects a soft band rather than a row of dots, changes how usable the room is after dark.
Colour rendering index describes how accurately a light source shows colour. It matters most over art, rugs, displays and food, and in kitchens and bathrooms where people are seen. A high-CRI source of 90 or above shows the actual colours in a painting or a worktop; a cheap low-CRI lamp flattens reds and makes skin tones look grey, and people notice the effect without being able to name the cause.
No. Interior work here is specific: under-cabinet and task lighting, cove and indirect lighting, toe-kick and stair lighting, display, shelving and art lighting, closets and pantries, and LED conversion of interior fixtures still running old lamps. It is lighting work by an electrical contractor, not a general remodel, and most of it runs alongside an exterior project so the view through the glass at night is designed as one picture.
