Oxley has developed the external LED lights for Gulfstream’s G500 and G600 executive jets. According to the company, the comprehensive suite has been developed especially for the new jets, delivering improved reliability and reduced through-life costs.

G500 executive jet

The three-year development process through design, prototyping, testing and manufacture was completed by a team of mechanical, optical and electronics engineers at the Oxley Priory Park site in Cumbria, UK, and Oxley Inc in Connecticut, US.

As part of the delivery of the project, there was a requirement for Oxley to provide sophisticated software and to develop complex lighting assemblies.

The Oxley team worked closely with the design and production departments at Gulfstream in Savannah, Georgia, throughout the development phase, creating a strong working relationship between the two companies.

Key application details

  • The Gulfstream lighting suite includes the exceptionally bright LED landing light, which meets the 400,000cd required industry standard. It is rated to operate for 27,000 hours mean time before failure (MTBF) compared with the 25 hours typical for halogen technology.
  • Total power consumption is 115W compared with the average halogen technology power consumption of 450W — representing a reduction of more than 70 per cent.
  • The units meet the stringent Aerospace Environmental and EMC requirements and are qualified to RCTA DO-160G. The Oxley landing light meets and exceeds SAE ARP 693 performance specifications — and does so over a full standard aircraft temperature range of -55°C to +70°C.
  • Smart technology has also been integrated into the lighting assemblies. The wing tip assembly (incorporating a navigation, anti-collision and separate forward-facing flood light) and the tail assembly (incorporating a navigation and anti-collision light) have built-in visible and discrete end-of-life feedback to enable predictive maintenance so as to prevent unscheduled maintenance that could inhibit aircraft despatch times.
  • The system utilises Oxley-designed software that is qualified to RTCA/DO-178B DAL C.
  • The full suite of LED lights includes a high-intensity taxi light and an ultra-low-profile ground recognition light, which protrudes 13.5mm outside the fuselage body. Oxley is also supplying wheel well, ice inspection and logo lights, pylon lights, entry door and over-/under-wing emergency ingress lights and service panel lighting, all offering 30,000 hours MTBF.

Oxley Developments

Oxley is a pioneer in the design and manufacture of high-quality components and systems, primarily for defence, aerospace, electronics and telecommunications industries.

Our main business is in night-vision lighting systems, LED solutions, EMI filters and interconnect components. Robust, reliable and high in quality, we design our products with performance, specification and longevity in mind.

We are renowned for our innovative work in lighting and developed one of the earliest night-vision lighting systems when night-vision goggles (NVGs) were first adopted for use by the UK Ministry of Defence. The company has since become a world leader in the supply of night-vision lighting for military aircraft, vehicles, shelters and naval platforms.

With more than four decades' experience, Oxley is highly regarded in the development of LED solutions to replace traditional incandescent and fluorescent lighting. From miniature LED components to integrated lighting systems, Oxley is the supplier of choice for both off-the-shelf and customised solutions.

Oxley is equally renowned for its electronic components business. Specialist products such as EMI filters and interconnection are all produced at our unique, high-tech facilities to bespoke and off-the-shelf requirements.

Established since 1942, the company has facilities in the UK and US, which include optical coating, machining, plating, manufacture and test facilities.
