One of our favorite features of the ProTac 2AA is its programmable switch that allows the user to select one of three different programs for its tailcap push-button switch. Settings include high/strobe/low, high only, or low/high. Compact and powerful, the flashlight features LED solid-state power regulation, which provides maximum light output throughout battery life for efficiency. Listed runtime is for alkaline batteries; it'll increase with lithium batteries. The ProTac 2AA has a glass lens and aluminum body and comes with a removable pocket clip and nylon holster.

Pros: Dual power options, programmable switch
Cons: Smooth body can become slippery
