The ML150LR1019 from Mag Instrument is the brand\'s initial mid-size flashlight that utilizes Lithium Iron Phosphate (LiFePO4) as its battery chemistry. This innovative adoption of rechargeable battery chemistry not only promotes better safety precautions compared to previous models, but also enables a quicker recharging time. In fact, this flashlight can be fully restored in approximately 2.5 hours from a completely drained state.
