The 640-LRS is an approved strobe light for boat crew and scheduled mission personnel listed on maintenance procedure card KB0107.0.
Typical SOLAS and USCG Approved strobe lights are effective signaling devices but have a visible range of only a few miles. The SIRIUS LRS (Long Range Strobe Light) combines the same characteristics of our SIRIUS Strobe with the long range signaling power of a focused beam strobe to reach out over great distances to searching aircraft and surface vessels.
