XT9778S LED Profile

XT9778S


All X-Trusion Profiles can be used as independent lighting sources for practical projects, or to complement lighting designs. We offer any length of Extrusion between 0.5M and 3M meaning that custom lengths between these sizes are fully achievable.

​

A deep, substantial profile for statement architectural lighting ​

The XT9778S is designed for projects where LED lighting needs to become a bold architectural feature. Measuring 97.6 × 78mm, this substantial aluminium extrusion creates a deep recessed housing for integrated LED lighting, allowing the profile to be incorporated directly into a suitable surface.

With its impressive overall dimensions and 55.4mm lighting source width, the XT9778S is designed for projects where the lighting feature needs to have a strong presence while still maintaining the clean, built-in appearance of a recessed installation.

Built For Creative Lighting Projects


Designed to be recessed into surfaces ​

The XT9778S has been specifically designed for recessed installation, allowing the extrusion to sit within a suitable surface rather than being mounted directly onto it.

The profile provides a generous 55.4mm lighting source width, creating a broad dedicated area for compatible LED lighting. Its 97.6mm overall width and substantial 78mm depth give the extrusion a distinctive presence, making it particularly suited to larger architectural lighting features.

The recessed format allows the profile to become part of the surrounding structure, helping create a deliberate and integrated finish.

​ A substantial profile for architectural lighting

The XT9778S stands out through its considerable size and deep construction. Rather than simply providing a narrow channel for LED strip lighting, this profile creates a much larger recessed structure around the lighting source.

The 55.4mm lighting source width provides a broad lighting area, while the surrounding aluminium construction gives the installation a strong architectural character.

The profile can be used as an independent lighting source for practical projects or as part of a wider lighting design where a larger recessed feature is required.

A profile designed to make an impact ​

With an overall width of 97.6mm, the XT9778S creates a considerably wider feature than many conventional LED extrusion profiles.

Its substantial 78mm depth also gives designers more scope to incorporate the extrusion into larger surface details. The result is a profile that can form a prominent part of the surrounding architecture while keeping the LED lighting itself neatly integrated within the structure.

For projects looking beyond a conventional slim LED channel, the XT9778S offers a much more substantial format.
