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.
WR3 is the recessed version of the Dan W3. This light has a special fitting clip design for attachment to a lifejacket so that only the ultra-low profile dome is above the fabric on the jacket. The light is specially designed for lifejackets used on passenger vessels with excavation or chute systems for mass evacuation of passengers.
