ProTac 2L-X USB LED Flashlight



A pocket-sized light with a big output, the Streamlight PolyTac 2L-X USB LED Flashlight offers the convenience of a rechargeable power supply—with no battery charging cradle needed. The included 18650 cell has its own micro-USB port for easy charging anywhere. The light can also run on two CR123A batteries. With a high-power setting of 500 lumens, a power-saving but still capable 40-lumen low setting and a strobe for disorienting an adversary or emergency signaling, the PolyTac 2L-X is suited to a range of professional, recreational and home uses. The tailcap push-button switch is used to cycle through the settings and you can select from three programs that put the light levels you use most often at your fingertips— high/strobe/low, high only, or low/high.
The type II anodized machined aluminum housing has an IP68 water-resistance rating, submersible to 3.3′ and impact resistant to 6.6′.
