Lighting Installation
Good Lighting Is Mostly Invisible Work
The part of a lighting job you see takes ten minutes: the fixture goes up, the switch goes on, the room looks better. The part that decides whether it works for the next twenty years happens in the attic and behind the wall. Is the circuit already carrying too much? Is the box rated for the weight of that chandelier? Are the recessed cans rated to touch insulation, or are they going to cook in a 130-degree Austin attic? Is the dimmer compatible with the LEDs, or will everything flicker at low settings?
Radiant’s licensed electricians handle all of it. We add recessed lighting to rooms that only ever had one center fixture, run new switch legs so a kitchen can have task lighting and mood lighting on separate controls, retrofit old incandescent cans with sealed LED wafers that stop leaking conditioned air into the attic, and hang the heavy fixtures on boxes and bracing that can hold them.
Older homes in Hyde Park, Tarrytown and Crestview often need a little more: a circuit that is already full, a box with no ground, or wiring from an era that does not like modern dimmers. We tell you what we find, price the fix in writing, and let you decide. If the project also calls for new outlets or smart switches or a ceiling fan, we do that in the same visit. Everything is backed by the Home Comfort Guarantee.
- Right fixture, right box IC-rated cans in insulated ceilings, fan-rated or heavy-duty boxes for big fixtures, LED-compatible dimmers. The details that stop callbacks.
- Priced before we start You approve a written quote first. If we find a full circuit or an ungrounded box, we price that separately and you decide.
- Clean finish Drywall cuts kept small, dust controlled, debris gone. You should be left with light, not a repair list.
Is This Your House?
When Homeowners Call About Lighting
Some of these are style problems. A few are electrical problems wearing a style problem’s clothes.
-
One dim fixture in the middle of the room
The 1960s layout. Recessed lights on a dimmer transform a living room, and we can usually feed them from the existing switch.
-
LEDs that flicker or buzz on the dimmer
An old incandescent dimmer driving LED loads. Swapping to a compatible dimmer fixes it. Occasionally a shared neutral is the real cause.
-
Old recessed cans that run hot
Non-IC cans with halogen bulbs, insulation pulled back around them, and a hole into the attic on every one. LED retrofits seal and cool them.
-
A kitchen with no task lighting
Shadows on the counter from a single ceiling light. Under-cabinet LED strips and pendants over the island, on their own switches.
-
A chandelier hung from a standard box
Ordinary ceiling boxes are not rated for heavy fixtures. We add the bracing and a proper box before something lets go.
-
Lights that flicker across the whole house
That is not a lighting problem. It can be a loose neutral or a panel issue and belongs on our repairs page. Call it in.
What We Install

Had a massive undetectable leak in a new home I just moved into... I was losing 1000+ gallons a day and was so worried about what was going to be the outcome. Then Radiant/ DAVID FARMER my saving grace, best plumber I've ever had, came to my rescue. It was a large job with doing all the leak detection and solving each problem but David was kind enough to teach me everything he was doing/what to look out for in the future to avoid issues later. It was an awful stressful situation that he made easy and fixed quickly. I think they are fairly priced and will work with budget constraints if needed. All I know is I know who my plumber is for life and I really appreciated all that Radiant and David did! UPDATE: used radiant for a AC repair and again they didn’t disappoint! April was my technician and she was AWESOME! So patient and kind and I learned a lot about my system that she showed me! Kudos again Radiant!!

We had another incredible experience with Radiant Plumbing & Air Conditioning that left us very impressed. Back in 2013, we hired this exact company to replace our old water heater, and the entire experience was absolutely outstanding. So, as soon as we realised it was time to replace our 2013 water heater, we didn’t hesitate to contact Radiant once more. Once more, Radiant and Christian, the technician, exceeded all expectations with their efforts. Christian is a true professional. We appreciated how Christian clearly explained all the different choices and worked hard to keep us near our budget limits. Our sincere thanks go to Christian and Radiant for their genuine support in helping us remain as close as possible within our financial limits. Christian was not only kind but also very respectful during his time at our house, and he did an outstanding job. Christian and the gentlemen who accompanied him performed their tasks excellently, demonstrating friendliness, kindness, and deep knowledge of their craft, which clearly marks them as true professionals. I want to express my gratitude to Radiant and also to Christian, thank you both!!

If you're in need of a new HVAC system because the one you got from the new home builder has broken down or is not working right, especially in this heat wave, Radiant can get you setup with a new and energy efficient system that keeps you cool and comfortable no matter the extreme temperature outside.
I highly recommend Radiant for cooling and heating. They are very friendly, knowledgeable and professional.
Their technician (Nathan B.) was outstanding and Breana the customer support manager provided stellar service and support.
They even have an annual warranty service program where they come out twice a year ahead of the winter months for heating system checkup along with system maintenance and then again in springtime to check the cooling ahead of the summer months for cooling system check and and any necessary maintenance to keep your system running efficiently and smoothly.
There warranty service is much cheaper than American HomeShield and does not require a copay or deductible. It's quite a bargain and it provides peace of mind.
Give Radiant a try and your heating and cooling worries will disappear. I absolutely recommend them with the highest rating available.

Indoor Lighting Questions
Can you add recessed lights to a room that only has one ceiling fixture?
Yes, and it is one of the most common lighting jobs we do in Austin’s older neighborhoods. The existing fixture gives us a switched circuit to start from. If that circuit has room for the added load, which is usually the case with LEDs, we run new cable through the attic to each can location and control the set from the same switch, often upgraded to a dimmer. With attic access above the room, the drywall cuts are just the holes for the cans. Without attic access, or over a second-floor ceiling with a floor above it, we talk through the options and price the extra work honestly.
Why do my LED lights flicker when they are on a dimmer?
Most of the time the dimmer was designed for incandescent bulbs. It controls light by chopping the power waveform, and an LED driver reacts to that with flicker, buzzing or a narrow range where the light jumps from off to bright. The fix is a dimmer rated for LED loads and, ideally, matched to the fixtures you have. Sometimes a mix of bulb brands on one circuit causes it. Less often, flicker that shows up across several rooms at once points to a loose neutral or a panel connection, which is an electrical fault rather than a compatibility problem. We can tell the difference quickly.
What is the difference between IC-rated and non-IC recessed lights, and why does it matter in Austin?
IC stands for insulation contact. An IC-rated can or wafer is built to run cool enough that attic insulation can touch it. A non-IC fixture needs a clearance gap, which in practice means someone pulled the insulation back and left a warm, unsealed hole into the attic above every light. In a Central Texas summer that attic can pass 130 degrees, so every one of those holes is pulling hot air into the room and conditioned air out. We install IC-rated, airtight fixtures and, when retrofitting old cans, use sealed LED trims that close the gap.
How do I pick the right color temperature for each room?
Color temperature is measured in Kelvin. Lower numbers around 2700K look warm and yellowish, like an incandescent bulb, and suit bedrooms and living rooms. Around 3000K is a soft white that works almost anywhere. 3500K to 4000K reads cleaner and brighter and is popular for kitchens, bathrooms and workspaces. Above that starts to feel like an office. The mistake we see most is mixing temperatures in one room, which makes the warmer lights look dingy. Pick one per room, or choose fixtures with selectable temperature so you can change your mind later.
