The Honeywell MALS System is a medium intensity approach lighting system that provides a visual lighting path for landing aircraft.

The MALS system usually is a 1400-foot-long array of lights but can be longer or shorter depending on local terrain and requirements.

A typical MALS system consists of the following light fixture components:
• 9 light bars each with 5 steady burning white PAR38 fixtures
• Threshold bar of 18 steady burning green PAR56 fixtures.

The MALS system can be mounted on 2-inch EMT, up to a 6-feet mounting height or on frangible towers over 6 feet. The system can be expanded to either a MALSR or a MALSF lighting system.

System control of the sequence flashing lights is accomplished through the master controller selecting one of three light intensities: low, medium, or high. The steady burning light system provides either local or remote control.
