I have the Klarus XT12-XML2-DGREY-A, and absolutely love that flashlight. However, someone got it wrong with the XT12GT. The first unit worked for about a week, and then suddenly the flashlight made some noise and just refused to turn on again.
This light is bright. It is a very powerful light.
Notes: The light will get hot on the high and turbo settings. Low and medium do not cause the light to get hot.
Pros: Small package. The light fits easily into a side pocket and perhaps a front pocket. It pushes the limits of being able to fit but it does indeed fit. It comes with a holster which may be the best option for some. The clip is strong and hold the light in place very well. The dual switch is a great feature to allow for low lumen operation when turbo isn't needed.
Cons: Not so much a con but more of a quirk. If you click the soft button while operating in a separate mode operated by the switch, the light will go to turbo. But then the light will not be able to turn off unless the switch is pressed again, rather than pressing the soft button. Just a quirk. I wouldn't say that I have any cons for this light.
It was a great purchase and works very well. This would be a great light for a police officer, security guard, bouncer, etc. Klarus as a brand seems very well made and high quality. The attention to detail is great.
I purchased this tactical torch a little over 4 months ago and have been using it for EDC (every-day carry). This light is extremely sturdy, which is noticeable simply by holding it. I've dropped it numerous times, has had car grease/oil on it, thrown into bags, etc. and never had a malfunction. I have even washed this tool with soap and water to get grime out of it multiple times; no rust in sight.
This flashlight is extremely bright on the high setting.
