Description:
All the listed flashlights have the C4 LED that Streamlight has recently been putting into each of their flashlights. The Protac 1AA and HL are both ten-tap programmable flashlights which you can switch the High-Strobe-Low order of occurrence, works really well for hard use flashlights that you want a specific option only and not others. I purchased all the above from Amazon (see links above), since they have the best deals.
