Ammonite Solaris + Accu Type 24 umbilical torch, E/O connection

LED SOLARIS NextGen is a universal primary dive light that is built to withstand the harshest underwater environments while reliably pumping out up to 4500 lumens of light that narrows to 6 degrees spot surrounded by a bright spill around the central beam. LED SOLARIS NextGen has a tough aluminum design, offering protection against knocks and scratches, substantial depth rating, and an ergonomic design that’s comfortable to use.

Connecting the head and separate battery means you can have a small torch that produces lots of bright light with extensive burn times.
ACCU TYPE 24 contains a lithium-ion (Li-Ion) battery pack, completely free of the so-called lazy battery effect and protected against overvoltage.
