The Research Engineers brand is synonymous with PAPI. Manufacturing the very first PAPI in the 1960’s, RE has remained a market leader ever since. Building upon the sound engineering principals and risk-averse methodology necessary for such a safety-critical piece of airfield lighting infrastructure, Research Engineers has developed the RE LED PAPI.
Contact Airport Lighting Specialists today to find out why the Research Engineers LED PAPI is the product of choice for the Royal Air Force, the Royal Australian Air Force and numerous major airports worldwide.
LED PAPI
For 6.6A Series Circuits
The new LED PAPI retains the features that made the original PAPI the most highly regarded and widely used product on the market. The compact dimensions and field replaceable projectors make maintenance easy and convenient. LED PAPI uses 75% less power than a lamped equivalent and can be powered by Series Circuit, Mains AC or 24 volt DC.
The modular concept
Interchangeable Projectors – Simplifying maintenance & spares management.
Minimal Field Maintenance – Individual projectors can be replaced in seconds.
Stable Reference – Projectors are mounted on a precision base plate.
