Basically that's what I absolutely ok for not even 50 sent got. Very good workmanship, good material and when turning on the lamp then not defined the term "flashlight" new, the Trustfire fits naturally because of their size in any pocket, even more so with the enlargement of the 3rd battery. I had previously stayed spontaneous Cree Flashlight (with a LED) at Lidl or Aldi (I forgot) bought. The lamp fits in one hand and in fact in any pocket. At that time I was extremely surprised because it was very bright beyond all expectations. Therefore, I naturally had with 7 Cree T6 LED's obviously abstruse ideas about the achievable brightness and was a bit disappointed. Yes of course it is much brighter than my Aldi lamp, but not at worlds brighter. If I place the lamp at night with the light cone up on my desk and the light beam illuminates the white ceiling, then my room is about as bright as I would turn on a 50 ... 60 watt incandescent lamp. If you hold your hand about 10 cm from the light beam heats the light skin that I have never experienced in a flashlight. The lamp itself is hot after 5 minutes in the region of the reflector warm after 10 minutes. The lamp developed a very bright center point, but also lights diffuse a little less light around this point, which I think is very good.
I use the lamp together with a high-speed camera for high-speed recording (slow motion) when analyzing machine processes. Therefore it is very suitable because it has a very bright, focused light without the hassle of wires and always with due to the torch form a flexible illumination from any angle no problem group.A battery pack lasts me about 20 to 30 minutes (3 battery).
