The Tool AA is a legendary light from Lumintop, well known for its durability and easy to use interface, as well as its incredible brightness.

This is the Premium Titanium 2.0 model, which now features a gold plated copper head to better dissipate the heat generated from its high output modes (previous models could get to hot without the copper heat sink). The Tool runs off a single AA battery, but for best performance a 14500 Li-ion battery is recommended.
