Centralized Lighting Control System Replacement in Houston

A centralized lighting control system runs every keypad and dimmer back to a central panel — typically mounted in a mechanical room or closet — that handles all the dimming and scene logic. LiteTouch, Lutron GRAFIK Eye, Vantage Controls, Touche, and older Crestron lighting all use this architecture. It is the opposite of distributed in-wall dimmers (each device wired only to its local fixture), and it is what makes whole-home scene control possible.

Look in your mechanical room, utility closet, or basement for a large metal panel with rows of labeled circuit cards or modules — and look at your wall keypads, which will have multiple unlabeled buttons rather than standard light switches. If your keypads run scenes (Welcome, Goodnight, Movie, Away) instead of just controlling one light, you almost certainly have one of these systems.

All four GRAFIK Eye generations are discontinued. The 3000 series ended in the early-mid 2010s, the 4000 followed, the 5000/6000 reached official End of Life in May 2014, and the 7000 received its hard sunset in December 2024. Lutron no longer supplies parts, technical support, or firmware updates for any of them. The 5000 and 6000 programming software requires Windows 98 and cannot run on a modern PC.

Yes. We are a LOXONE Platinum Partner serving the greater Houston metro area — including River Oaks, Memorial, The Woodlands, Spring, Cypress, Sugar Land, and Katy — and legacy lighting control replacement is one of our core specialties. Free on-site assessment included for every project.

In most cases, yes. These systems use low-voltage cable between each keypad and the central panel, and LOXONE's Tree bus typically runs over the same cable. We confirm reuse during the on-site assessment by checking gauge, run length, and termination. When the existing cable cannot be reused, we add new runs only where required — avoiding full re-wiring of the home.

A typical residential cutover takes 3 to 5 working days from hardware removal to a fully commissioned system. Larger estates and commercial buildings are phased floor-by-floor or wing-by-wing so the building stays operational. We schedule around your calendar and coordinate any required electrician and AHJ inspections.

No. Lighting control replacement swaps the control system — the panel, dimming modules, and keypads — not the fixtures themselves. Your existing recessed lights, chandeliers, sconces, and lamps stay in place. We update fixture drivers only if your current ones are incompatible with modern LED dimming, which is the most common reason older systems start to flicker or fail to dim properly.

Most residential replacements range from $15,000 to $40,000 depending on home size, zone count, and whether additional automation (climate, audio, shading) is bundled in. Commercial floor-by-floor migrations start around $25,000 per floor for medium-density buildings. We provide a detailed quote after a free on-site assessment — no obligation.

Yes. We commission the system so every existing scene name and keypad function is recreated before we hand it over. Day-one familiarity is the explicit goal — you will not need to learn new button positions to run your home. New capability (mobile app, voice, schedules, occupancy) is layered on top as you choose to use it.

Yes. LOXONE installations transfer in full to new owners with no dealer fees, no subscription resets, and no admin lockout — every Grizzly Tec client receives the admin password. Listing agents in River Oaks and Memorial routinely highlight a working, owner-controlled smart home as a differentiator. A failing LiteTouch or GRAFIK Eye system, by contrast, is now showing up as a buyer-side inspection objection.

Yes — especially for commercial buildings and large estates. The most common phased approach replaces the central processor and the highest-traffic floor first, runs that floor on LOXONE while the legacy panel still serves the others, then migrates the remaining floors over weekends. Egress and emergency lighting are coordinated with the AHJ so the building stays code-compliant throughout.

Both can do the job, but the ownership model is fundamentally different. LOXONE gives you the admin password and the design files on day one; you can change scenes, add devices, and integrate new systems without calling a dealer. HomeWorks QSX requires a certified Lutron dealer for any future programming change and typically carries an annual service plan. For owners who liked that their old LiteTouch or GRAFIK Eye system was theirs to manage, LOXONE is the closer philosophical match.
