Three output levels provide 32 hours on High, 112 hours on Low, and up to 298 hours in Eco Mode. The ML300L 3D combines LED Heat-Sink Technology, Quick Focus® spot-to-flood adjustment, QuickClik® electronic switching, four selectable function sets, dynamic power management, rugged aluminum construction, a knurled grip, IPX4 water resistance, and 1-meter drop resistance.

1. 403-Meter Beam Reach, Up to 298-Hour Runtime & 746 Lumens

The ML300L 3D combines high-output illumination with long battery life and a concentrated long-range beam. At maximum output, the flashlight produces 746 lumens and projects its beam up to 403 meters (approximately 1,322 feet) with 40,596 candela of peak beam intensity.

Three output levels allow users to balance brightness and battery life according to the task. High delivers 746 lumens for up to 32 hours, Low delivers 102 lumens for up to 112 hours, and Eco Mode delivers 23 lumens for up to 298 hours. The maximum Eco runtime equals more than 12 days of continuous light, making the 3D configuration particularly useful for emergency preparedness, extended outdoor use, security applications, and situations where minimizing battery changes is important.

2. LED Heat-Sink Technology with Quick Focus® Spot-to-Flood Beam Control

The ML300L 3D uses LED technology with LED Heat-Sink Technology to help manage heat generated by the LED and support efficient brightness and power management. Its optical system incorporates Maglite® Quick Focus®, allowing the beam pattern to be adjusted rapidly directly from the flashlight head.

With less than a ¼ turn of the head, the beam adjusts from a concentrated spot for longer-distance viewing to a broad flood for illuminating a wider nearby area. This provides fast beam control for searching, outdoor navigation, inspections, work areas, emergencies, security duties, and close-range tasks.
