Licensed electrical contractor serving North Texas
Commercial electrical service
Koryente performs LED lighting retrofits for commercial buildings and facilities across North Texas, converting outdated fluorescent and HID fixtures to efficient LED equipment. The work covers interior conversions, parking and pole lighting, and occupancy or daylight controls, for property owners and facility managers tackling a full building retrofit or a single problem area.
Our service includes
Fluorescent troffers, high-bay fixtures, strip lights, and older HID fixtures are converted to LED equipment sized to the space.
Pole-mounted and area fixtures serving parking lots and loading areas are retrofitted or replaced with LED equipment matched to the existing wiring.
Occupancy sensors, photocells, and daylight-responsive controls are added so fixtures run only when a space is in use or light is low.
Where a fixture stays in place, Koryente bypasses or keeps the ballast as needed and matches the LED driver to any existing dimming.
Fixtures beyond a straightforward retrofit are replaced outright, and old fluorescent tubes and ballasts are removed and disposed of properly.

Planning guidance
Converting a fluorescent or HID fixture to LED can mean a lamp or kit installed with the ballast bypassed, or the fixture replaced outright with LED equipment and a matched driver. Which approach fits depends on the fixture's condition and whether the ballast is close to failing anyway.
Dimming and control compatibility is where retrofits most often go wrong. An LED driver has to match the dimmer, sensor, or automation already on the circuit, not just carry an LED-ready label. Koryente reviews existing controls before specifying equipment, so the retrofit dims smoothly and sensors behave as expected.
What to expect
Fixture inventory and site walk
Koryente counts existing fixtures, notes ballast condition, and flags areas with uneven or inadequate light.
Photometric and load review
Light levels are checked against how the space is used, and the proposed LED load is checked against the existing circuits.
Fixture and control selection
Retrofit kits, fixture replacements, and compatible drivers or controls are specified fixture by fixture, not as one blanket product.
Installation and commissioning
Fixtures are converted or replaced and every circuit tested under load, and old tubes and ballasts are cleared from the site before crews leave.
Serving North Texas
North Texas keeps adding commercial and industrial square footage — retail and office growth along the US-75 corridor and the industrial base expanding around Sherman and Denison chief among it — and new space typically opens with fixtures a full generation ahead of what's still running nearby, which is the exact gap a retrofit closes.
Koryente's lighting retrofit work includes an interior and exterior LED lighting retrofit for the recycling side of Waste Connections' plant in McKinney, done alongside electrical work supporting the site's office remodel, plus ongoing electrical service for Pilot and Flying J locations across Texas that covers interior and exterior lighting alongside refrigeration, HVAC power, and general repairs on active, occupied sites — the same access constraints a North Texas retrofit faces when work has to happen around business hours, not a full shutdown. Permits go through whichever city or county has jurisdiction over the property.
Common questions
A retrofit either installs LED lamps or a kit into an existing fixture with the ballast bypassed, or replaces the fixture outright with LED equipment and a matched driver. The right approach depends on the fixture's condition and how many fixtures need converting.
Usually, yes, for a fluorescent fixture converted with LED tubes rather than replaced outright. The ballast is removed and the fixture rewired to run the tubes directly, since most fluorescent ballasts aren't compatible with standard LED replacement tubes. Bypassing it incorrectly commonly causes flicker or early tube failure.
Cost depends on how many fixtures need converting, whether they're retrofitted in place or replaced outright, the complexity of any new controls, and whether the work happens in an occupied space that limits access to certain hours. Koryente prices from a fixture inventory and site walk, not a flat per-light rate.
A straightforward lamp or fixture swap on an existing circuit usually doesn't require one. Adding new circuits or control wiring for sensors or dimming typically does, depending on which city or county has jurisdiction over the property. Koryente identifies which parts of a retrofit trigger permitting before work starts.
