The TAC660XL from Bayco Products, a part of the Nightstick range, is a compact yet powerful rechargeable tactical flashlight that boasts a dual-switch functionality. This is further augmented by an 1100 lumen LED light that, combined with a high-efficiency, deep parabolic reflector, throws a strong and focused beam of light up to 228 meters. This flashlight offers users the convenience of either momentary or constant-on functions via its bezel and tail-cap switches.Constructed from aircraft-quality 6061-T6 aluminum for optimal strength and durability, the flashlight has a Type III hard-anodized finish for a robust and resilient surface. A rapid drop-in charger is part of the package for quick reloads of power, providing convenient and efficient energy replenishment. The power supply for this flashlight comes from a rechargeable Lithium-ion battery. However, it also possesses the flexibility to operate on a pair of CR123 batteries. The purchase includes the light itself, drop-in charger, rechargeable Li-Ion Battery, AC & DC Power Supplies, CR123 Battery Carrier, and the Charger (please note: batteries are not included). Please be aware that rechargeable CR123-style batteries are not compatible with this model.
