The NiteCore SRT7 Revenger is a top processed flashlight. On the Internet there is a video, since they have been tested even to 60 meters in the water under pressure. What is a super power. The infinitely variable adjustment of luminance is a big advantage over other lamps. The three-color LED is not bright, but fulfill your purpose. Each color for a specific function, which I will not explain in detail here. The explanation can be found on the net. I find this very useful features. Very handy, very bright light at this size.
