Bridlington Spa

The client had large square decorative ceiling luminaires, illuminated by 6 x 55W TC-L lamps. With the constant maintenance and ever decreasing supply of fluorescent lamps, the REGEN Initiative was approached to find a long term sustainable solution. 

The Challenge & the Clients Brief

The client requested a preservation-focused upgrade for their historic, decorative glass-fronted luminaires. While determined to keep the original architectural housing, the existing system—which relied on three traditional fluorescent lamp trays—was no longer meeting modern standards.

The core objective was to completely modernise and future-proof the fixtures while respecting their aesthetic heritage. Additionally, the brief demanded a significant upgrade to the quality of illumination. This required a dual-focused approach: drastically increasing the overall lumen output while simultaneously enhancing the colour rendering index (CRI) to elevate the visual experience and atmosphere of the space.

3D Visualisation

The new LED Light engine was designed to mount to the existing metal trays to make reinstallation much quicker.  The 3D visualisation helped the client understand the technical proposal 

Design Drawings

The new LED Light engine features a streamlined mechanical design engineered specifically to interface with existing metal trays. By utilizing the legacy mounting footprint, installers can bypass complex structural retrofitting. This compatibility drastically reduces labour times and simplifies the entire reinstallation process

Manufacturing

We Upgraded the existing 6 x 55W TC-L fluorescent fixtures with this premium, all-in-one Retrofit LED Gear Tray. Supplied as a fully integrated, one-piece unit complete with pre-wired drivers and LED modules, this tray guarantees that the onsite refurbishment of the existing commercial luminaires is quick, simple, and hassle-free. By utilising the existing carcass, this solution drastically reduces installation time, minimises waste, and lowers overall project costs.

Key Technical Specifications

  • Light Source: High-quality Tridonic 4000K (Cool White) LED boards.
  • Control Gear: Dual Tridonic drivers (one dedicated to each side).
  • Optical Cover: High-transmission, frosted PMMA (Acrylic) diffuser.
  • Legacy Replacement: Directly replaces 6 x 55W TC-L fluorescent lamps.

 

Final Result

The final installation successfully demonstrates a brightly lit, highly aesthetic decorative luminaire engineered for optimal light distribution and minimal glare. By integrating high-efficiency Tridonic LED boards, the system ensures a prolonged operational lifespan, resulting in a drastic reduction in ongoing maintenance cycles and labour costs. Furthermore, this upgrade achieves exceptional energy efficiency, delivering over 120W in power savings per luminaire compared to legacy systems. This reduction in power consumption directly correlates with lower carbon emissions and a rapid return on investment.
