ELF battery operated portable emergency runway lights are made from tough polycarbonate. They can be placed on the strip from a slow moving vehicle and operate via a push-on switch. Each light is powered by two 6 Volt (dolphin torch type) disposable batteries.
ELF lights can be supplied with either clear or coloured lenses. Clear (white) is used for runway edge lights. Blue is used for the taxiway and apron, and Green or Red/Green for the threshold/end.
Lights must be stored ready for use with relatively new batteries. Batteries should be kept in stock and checked to ensure lights are ready for immediate operation. An affordable alternative to solar powered lights.
