This is a reproduction of Princeton Tec Charge Mpls. In addition to being able to attach directly to the ARC rails on Ops-Core helmets, it also includes a mount that attaches directly to the helmet rim, and a mount for attaching to MOLLE parts such as a vest.
It operates on a single AA battery for good cost performance, and the flexible arm makes it easy to adjust the irradiation direction.
Battery: 1 x AA battery (not included)
Due to differences in the shape of the helmet manufacturer and individual differences, processing may be required for installation and may not be possible to install.
