The Maglite® ML300LX® 3-Cell D LED Flashlight is a full-size, high-performance LED flashlight designed for professional work, security, emergency preparedness, outdoor activities, camping, vehicle use, home use, and general-purpose illumination. Powered by three standard D-cell alkaline batteries, it produces up to 746 lumens, projects a beam up to 403 meters (approximately 1,322 feet), and delivers 40,596 candela of peak beam intensity. Three power levels provide 32 hours on High, 112 hours on Low, and up to 298 hours in Eco Mode. The ML300LX 3D combines LED Heat-Sink Technology, Quick Focus® spot-to-flood adjustment, QuickClik® electronic switching, four selectable function sets, rugged aluminum construction, an aggressive knurled grip, stealth matte finish, IPX4 water resistance, and 1-meter drop resistance.

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

The ML300LX 3D combines high-output long-range illumination with extended battery life. 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 let users balance brightness and battery life. High provides up to 32 hours of runtime, Low provides up to 112 hours, and Eco Mode provides up to 298 hours, or more than 12 days of continuous operation. This combination makes the ML300LX 3D practical for professional work, security, extended outdoor use, emergency preparedness, inspections, and situations where long battery life matters.

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

The ML300LX 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®, providing rapid adjustment of the beam directly through 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 gives the user practical beam control for searching, inspection, navigation, outdoor work, emergency response, security, and close-range tasks.
