The new SEAL-M1 is an autonomous base module of a System for Expeditionary Airfield Lighting designed for NATO-STANAG Minimum Operating Strips (MOS) airfields and applicable for any temporary airfield/helipad lighting installation or replacement. This LED based system reduces drastically the maintenance of the system and has an operation period which is more than double with respect to the standard systems. In addition to the NVG compatibility it allows the covert operations thanks to the infrared LEDs. Use and installation are improved significantly with the minimization of all type of cabling.
