Whether you're on a nighttime patrol, navigating a trail in the wilderness, inspecting a dark job site, or just preparing for an emergency, the Streamlight ProTac HL USB 88052 delivers professional-grade performance in a compact, rugged package. Its 1000-Lumen LED light creates a powerful beam reaching up to 219 Meters, giving you confident visibility even in pitch-black conditions. With selectable brightness levels from low to high (and a strobe option), you can adapt to any situation from subtle map reading to full-blast illumination. The rechargeable Li-ion battery keeps things convenient and cost-efficient, while the ability to run on two CR123A lithium batteries provides an essential backup when power sources are scarce. Built tough with an anodized aircraft-aluminum body, sealed glass lens, and IPX4 water resistance, this flashlight is engineered to handle drops, rain, and rugged conditions. Add TEN-TAP mode selection and ergonomic tail-switch control and you get a versatile, durable flashlight ready for work, wilderness, or emergency use.
