Vista 2 Elevated High-Intensity Airport Light (Signalight-made) vs PAPI & Airfield Photometric Calibration System — mobile (Unika / PAC, distributed by Vardhman Airport Solutions)
Spec comparison for two products on Aviation Souk. Both compete in Runway Lighting & Airfield Electrical.
Runway Lighting & Airfield Electrical
Vista 2 Elevated High-Intensity Airport Light (Signalight-made)
by Signalight (Electromax SRL)
VISTA-series elevated high-intensity airport lights for non-precision runways, delivering five-step brightness control from 1% to 100% with IP67 protection rated to −55 °C.
Runway Lighting & Airfield Electrical
PAPI & Airfield Photometric Calibration System — mobile (Unika / PAC, distributed by Vardhman Airport Solutions)
by Vardhman Airport Solutions
A paired photometric calibration solution — vehicle-mounted mobile runway/taxiway light measurement and tripod-based PAPI angle calibration — enabling airfield maintenance teams to verify ICAO and FAA photometric compliance on the airfield without the airport closing.
