It looks to more like the Streamlight TT1L to me just in polished aluminum and a rechargable batt,if only there was a way to use the LEDs without having to cycle through the xenon bulb each time. it is 4 1/2 inches the SL TT1L is 4 inches.My first addition would be 1 or 2 charged batteries to accompany it on journeys.It says 3 1/2 hours to charge a batt
