Same as the 3320 flashlight, but in an LED version. the PM6 3330 led flashlight is made of lightweight xenon polymer that's corrosion proof, resistant to extreme temperatures, and extremely strong. it uses a 1 watt LED and is powered by 2 CR123 lithium cells (included). A black oxide coated steel clip is built-in and the one-handed tail switch activates the 3330 on, for constant light or momentary blink.
