Really Good


I use the light for late night drop and hook and inspections. Purchased this light because of being able to use both cr123 and AA battery. So you get the brightness of cr123 and can run into any gas station if you lose your spare battery. I also really prefer simple operation of a tailcap switch. Only downside is Streamlight reccomends not using rechargeable batteries. Overall really good light!

Great Light! Will not leave home without it!


I have carried mine for years and love it. The option of using AA batteries is huge with the price of the 123 Batteries.
