Product Specification

Kellwood Lighting's designs demonstrated the 460W Ayrton 3 Series was the right product
for the job:

• IESNA Type IV Short Optics provided maximum forward throw, ensuring target lux levels were achieved across the extent of the aprons, while minimising tilt
• Observer Points at ground level and pilot eye-level minimised glare
• Environmental Temperatures, Operating Hours and Lumen Maintenance (TM21 Calculated L90B10>160,000hrs) were assessed to ensure designs had an application-specific Maintenance Factor
• In the unlikely event of overheating, Driver Safety Features included a temporary power de-rating ensuring continued operation, rather than a full thermal cut-out
• Iterations of Luminaire Tilt and Direction optimised minimum lux levels and uniformity while ensuring upward light ratio (ULR) was within tolerance
• Marine Resistant surface-finishes and stainless steel fixings (saltspray tested in accordance with ISO9227:2012), and an IP67 rating, protects the product and the investment

The Results

On-site lux surveys confirmed the modelling of the new lighting system had been accurate; light levels complied with the project brief.

Perhaps more pleasingly, on-site feedback from staff was positive. Pilots, when taxiing and stationery, as well ground handling staff, felt it was a more comfortable environment to be working in.

The airport will enjoy both environmental and economic benefits from a 40% reduction in energy costs.
