DW Windsor, a UK manufacturer of exterior lighting equipment for public and commercial outdoor applications, has completed a bespoke lighting upgrade for Gosport Harbour, replacing over 100 lanterns while maintaining the distinctive visual identity of the original scheme first installed to mark the millennium.
Located on the edge of the Solent, Gosport Harbour’s lighting has long featured a unique design inspired by maritime forms, specifically echoing the shape of a ship’s masthead. The new lighting retains this heritage character while introducing energy-efficient LED technology and improved performance.
DW Windsor was commissioned to provide a like-for-like design that respected the harbour’s historic setting.
The original scheme used two separate light sources: a SON lamp for white functional lighting, and a metal halide lamp for decorative blue light.
The updated version replicates this concept using two dedicated LED sources: one to deliver precise white light via modern optics, and another to provide the distinctive soft blue glow that has become synonymous with the harbour’s night-time appearance.
The new lanterns were developed to withstand the challenging coastal environment.
Manufactured with marine-grade paint finishes, high-grade stainless steel components, and robust gasketed seals, the fittings were tested in DW Windsor’s in-house laboratory to ensure compliance with relevant Ingress Protection (IP) ratings.
The updated lanterns are compatible with the original custom-designed columns and brackets, allowing for visual consistency and minimising installation disruption.
To accommodate the complex design brief, the manufacturing process included a combination of cast components, CNC-machined parts, and specialised plastics.
Given the size and weight of the luminaires, additional lifting points and reinforced couplers were incorporated to support safe handling and fitting on site.
The project was delivered in partnership with contractor Enerveo as part of a Private Finance Initiative (PFI) agreement with the local authority.
Martyn Dancer, Interim Regional Director (PFI’s South) at Enerveo, comments, “This project demonstrates what can be achieved when collaboration, craftsmanship, and respect for heritage come together.
“Working alongside DW Windsor, we’re proud to have played our part in delivering a lighting solution that honours Gosport Harbour’s history while providing a resilient, sustainable future for this iconic waterfront.”
Alex Winship, Specials Product Design Manager at DW Windsor, adds, “This project required balancing heritage and performance in a challenging environment.
“From how a lantern looks during the day to how it performs at night, and how it stands up to the elements over time, every detail matters.
“The key is flexibility: listening to the client’s needs, understanding the character of the place, and adapting our designs to suit.”
