variable-output tailcap-switch LED flashlight

  (1 review)


The T20 is a compact, robust and affordable LED flashlight featuring a tail switch and powered by long-lasting CR123A batteries.  The T20 is a great tactical or emergency light, with simple, intuitive controls and a highly efficient CREE XP-G2 R2 LED that throws a long, powerful beam while maintaining long battery life.  Twisting the mode selector head cycles through three brightness levels, including a max of 380 lumens out to 525 ft, and a disorienting strobe mode.  The T20 is constructed of tough hard anodized aircraft-grade aluminum, and its tail switch is well suited to tactical techniques for employing a light, allowing momentary activation as well as clicking on and off.  On a duty belt, in a purse, or in a bug-out bag, the rugged and practical T20 is a great choice.

The specifications in the chart to the right claim to ANSI/NEMA FL1-2009 Standards. Tests are performed with 2x CR123A(3.0V) 1500mAh batteries.

Olight T20

Frank King Charleston, SC
I purchased this light as a pocket light to carry at work. Although it is just a tad large for a pocket light, I was willing to sacrifice the pocket space if the claims were true with this light. When it arrived, I was blown away by the brightness level and construction. I never thought that a flash light could be TOO bright, but I find myself running this light on medium intensity because the brightness on high can be blinding when reflecting off of items that are close by. I would recommend this light if you are looking for a smaller flashlight with a HUGE potential. I just wish that there was a suitable rechargeable battery (other than the 18650 which is lower voltage) that could power this unit. Other than that, GREAT Purchase!
