The ML150LR offers eco, low, and high power settings as well as a strobe mode, with momentary and constant-on operation, all controlled from a side-mounted push-button switch. The settings are further organized into four function sets: General (high, low, eco), Outdoor (high, low, strobe), Law Enforcement (momentary, high, eco) and Tactical (momentary, high, strobe). Runtimes range from 3.3 hours on high to 79 hours on Eco. Spot-to-flood focus is adjusted with the classic Maglite quarter-turn head-twist mechanism. The light's three lithium-iron phosphate batteries recharge in about 2.5 hours and are rated for up to 1000 charge/discharge cycles. Measuring 10.7'' long and weighing just under a pound, the light features an anodized aluminum housing and is IPX4-rated water resistant. The charging cradle has a status indicator light and an ergonomic quick release button and is designed to grip the light securely, even upside down or in a moving vehicle on rough road.
