All Daniamant Lifejacket lights are designed to deliver, as a minimum standard, the 0.75cd output specification and 8 hour duration required by IMO SOLAS regulations. The L7A2 light slides into the recessed housing unit which is permanently mounted in the life jacket, leaving only the small dome and light visible. The light is safe from any damage when the jacket is used in a safety drill and during any evacuation. The light is easily replaced after 5 years. Note: The L7A2 supersedes the earlier L7A which is no longer available. The L7A2 also fits into the old L7A receptacle to ease retrofit.
