Ketra is Lutron’s full-spectrum intelligent-lighting family for projects that need unusually broad white-light control, precise color and high-quality rendering. Current Ketra sources span approximately 1,400K to 10,000K and can also produce saturated color, giving designers a single Lutron light source for natural-white scenes, artwork, entertaining and architectural effects. Regent5 coordinates the fixtures, HomeWorks control, keypads and programming as one lighting system.
Ketra goes beyond ordinary tunable white by combining a very wide white-light range with full-color capability. Most residential projects use the white-light performance every day and reserve saturated color for selected entertaining, art or architectural scenes. That keeps the system visually refined while preserving the flexibility that makes Ketra distinct from Rania and Lumaris.
The same space and fixture layout can support very different stored scenes. Each scene can hold its own color temperature, intensity and fade behavior so the room changes through programming rather than through added fixtures.
NATURAL
Interior light can be tuned closer to the daylight at the windows so the room and exterior view feel more visually connected.
COLLABORATE
Accent channels lifted onto the art and the decorative elements, general illumination pulled back. The room becomes about what is in it.
MEDIA
Overhead down for a screen, perimeter held low but present so people can still read and see each other. The scene nobody thinks to ask for and everybody uses.
BLUE MOON
Ketra can place saturated color in selected architectural zones while other fixtures remain at usable white light, a capability that tunable-white-only sources do not provide.
Ketra uses a four-channel light engine to create both broad-spectrum white light and saturated color from the same source family. That allows a room to move between natural-white everyday scenes and occasional color effects without changing fixture types.
With HomeWorks, Ketra can vary color temperature and intensity over time through Lutron Natural Show programming. Regent5 tunes the schedule, levels and fade behavior to the residence so daytime settings feel brighter and more neutral while evening scenes become warmer and lower without abrupt transitions. The result is treated as part of the interior lighting design rather than as a decorative effect.
Ketra is often concentrated in the rooms where people spend the most time and where materials, artwork and changing daylight matter most: great rooms, kitchens, dining rooms, primary suites and art-focused spaces. Rania, Lumaris or conventional Lutron-controlled fixtures can serve other areas, allowing the lighting plan to match the performance of each source to the room rather than forcing one family everywhere.
Coastal Source offers Ketra Ready outdoor lighting, including solid-brass fixtures designed around compatible Ketra lamps. Regent5 can coordinate those fixtures with gateway placement, cabling, landscape zones and Lutron programming when a project wants indoor and outdoor lighting to share a consistent control strategy.
Using compatible Ketra sources outdoors can help the terrace, facade and landscape participate in the same white-light and color scenes as the interior. The outdoor design still needs its own fixture selection, weather-rated infrastructure, power, gateway coverage and service access, so Regent5 coordinates the landscape-lighting details separately while programming the finished scenes as part of the broader Lutron system.
Modulus Bullet Light
SOLID BRASS, TAKES THE KETRA S30
A heavy duty solid brass fixture built to accept the Ketra S30 lamp. Brass is the right material outdoors on the Peninsula because it weathers rather than corrodes, and it is what allows a fixture to still be serviceable a decade after planting has grown around it.
Ketra Gateway Outdoor Enclosure
HOUSES THE CLEAR CONNECT GATEWAY TYPE X
A weather-rated enclosure can place the Lutron Clear Connect Gateway Type X closer to compatible outdoor fixtures where the design requires it. Gateway location, network connection, power and wireless coverage should be planned as part of the outdoor lighting system rather than added after installation.
The gateway is the detail that decides whether an outdoor Ketra design works. Wireless control has to actually reach the far end of a property, past masonry, planting, and distance, and siting that enclosure correctly is a design decision made against the site plan rather than something resolved on the day. We survey the run distances before specifying, because a beautiful fixture that drops off the system in the far corner of a garden is a service call every month.
Coastal Source also builds outdoor audio, and the same buried cabling and connector system carries both. Where a project wants lighting and sound through a garden, planning them together at trenching stage costs a fraction of adding the second one later.

One fixture layout can support both restrained everyday scenes and occasional color scenes through Ketra programming.
EVERY DAY
A warm-white landscape scene keeps planting, architecture and material colors visually natural for everyday use.
OCCASION
The same compatible fixtures can shift into a programmed color scene for entertaining or special occasions.
For most residences, the everyday landscape scene should remain the priority. Ketra's value outdoors is that the same compatible fixture family can preserve high-quality white light for daily use while retaining optional color capability for selected occasions.
Ketra is designed for Lutron control; on Regent5 residential projects the current reference platform is HomeWorks. HomeWorks scenes can coordinate Ketra color temperature, intensity and color with conventional lighting loads, architectural keypads and compatible shades. Existing systems should be surveyed before a retrofit because processor, gateway, software and Ketra product generation all affect compatibility.
Ketra, Rania and Lumaris can be reviewed with Regent5 by appointment so homeowners, architects and interior designers can compare white-light range, dimming, color capability and how finishes read under each source. Bring plans and material samples when possible, and tell us which systems you want to evaluate so we can confirm what will be available for the visit.

Where we work.
Regent5 designs, installs and supports Lutron Ketra lighting across the San Francisco Bay Area and Northern California, including the Peninsula, San Francisco, South Bay, East Bay, Marin, Wine Country and Carmel/Monterey, coordinating tunable-white and color lighting, Lutron controls and shades, electrical infrastructure, programming and long-term service with the project team.
Regent5 also designs Ketra lighting for offices and other select commercial spaces.
Ketra is Lutron’s full-spectrum, tunable light platform. Current Ketra products support high-quality white light and color control, allowing the same system to move from warm or cool white to saturated color while remaining integrated with Lutron HomeWorks.
Ketra is designed for Lutron control; on residential projects the current reference platform is HomeWorks. Exact compatibility depends on the Ketra product generation and the Lutron system generation, so existing systems should be surveyed before a retrofit is specified. Regent5’s primary Ketra service area is the San Francisco Bay Area and Northern California, and Ketra, Rania and Lumaris can be compared in person at the Regent5 Showroom & Design Center.
Current Lutron support lists Ketra D2, D3 and D4R downlights, plus A20, S30, S38 and Track Luminaire products. Product generations change, so Regent5 confirms the current fixture, trim and application options during specification rather than relying on an old catalog list.
Yes. Regent5 designs, installs, programs and services Ketra as part of residential Lutron projects, coordinating the light sources, HomeWorks control, keypads, shades, electrical requirements and commissioning as one scope.
Ketra pricing is project-specific because the total depends on fixture type, quantity, trims, HomeWorks infrastructure, controls, programming and which rooms use Ketra versus Rania, Lumaris or conventional fixtures. Regent5 develops the lighting and control scope from the plans before providing project pricing.
Potentially, if the existing HomeWorks processor, gateway and Ketra product generation are compatible. Lutron’s current support includes retrofit-oriented Ketra hardware such as D4R, but Regent5 verifies the processor, gateway, software and ceiling conditions before quoting an upgrade.
