Streamlight ProTac HL 4

A powerful 2200-lumen maximum brightness level, a self-defense or signal strobe, and a strong aluminum housing make the Streamlight ProTac HL 4 Flashlight a good choice for professional, recreational, or around-the-house use. A tailcap push-button switch turns the light on and off and selects output levels. The light can be programmed in three modes—high/strobe/low, high only, and low/medium/high.
Power is supplied by four included CR123A batteries, and the light can also run on two optional 18650 cells. Output is regulated to ensure consistent performance across the batteries’ lifetime. Rated IPX7 for water resistance, the light is both submersible and impact resistant to 3.3′. This item comes in clamshell packaging.
