Red, Green, Blue, and White LED’s

On top of its ultra-bright XM-L2 U2 primary LED, the LD75 also packs red, green, and blue LED’s. Each of these modes offers preserved night vision, enhanced, map reading, and optimal blood tracking for hunters, hikers, tactical users, and adventurers. Accessing the various modes is easy with the light’s three side-switch configuration. Each colored light has a single mode, while the primary white light has five outputs to choose from.

Advanced Circuitry

The LD75’s double circuit design provides flexible power options so you can power your light in a jam. Normally, the light runs off of four 18650’s or eight CR123’s. Thanks to its advanced circuitry, the light can also run off of only two 18650’s or four CR123’s. The light is fitted with reverse polarity protection and thermal protection which guards against improper battery installation and high temperatures.
