The ML300L LED 3-Cell D Flashlight from Maglite is a focusable white LED light featuring 625-lumen maximum output, several power and lighting modes, and a water- and impact-resistant aluminum housing. The ML300L offers momentary and constant-on operation, high, low, and eco modes, and an emergency strobe. The high output mode flashlight delivers 625 lumens of light for 16 hours, the low setting runs for 77 hours, and eco mode runs for 117 hours. You can arrange the switching sequence of these modes to suit your needs by selecting the General, Outdoor, Law Enforcement, or Military priority setting. Activation and switching between the modes are performed via a push button located on the side of the body. Quick-Click switching allows changing between output mode sequences. The flood-to-spot quick focusing is performed by twisting the head in 1/4 of a turn. The housing is water resistant and impact resistant to 3.3' and has a textured handle and tailcap for a secure nonslip grip.
