Those like me who had lancer reliable and Light lamp needs and but so far only cheap junk has just kind of lit up will be very surprised at this lamp! These are great for a lamp of true (!!!) ~ 1000 lumens. This is confirmed by independent tests by amateur enthusiasts and specialists in div. Flashlights forums. The lamp has the (with beginners) with a protective circuit board (PCB) are operated with a 18650 LiOn battery should be provided and still provides the highest possible discharge current to the max. extract possible performance out of the circuit. Accordingly, you should also use good charger like Xtar, NiteCore, Efest etc. Please no charger and battery's with a "... fire" in the name! The net is full of reports of how dangerous can that be, please inform you! Good battery's include AW, Keep Power, Fenix, NiteCore, Efest, Panasonic, LG etc. The lamp is very well made, use the Tailcap to the battery's also carries the on / off switch can be screwed smoothly and ends suddenly and without play, the movement when it is fully screwed. This feels very valuable as the whole feel of the lamp. The positive terminal in the lamp may be used provided with a small spring so that even battery's with Flat top (ie flat positive terminal). In addition to the power switch on the tailcap there is a mode button once forward within reach. With this, the individual lighting levels can be selected: Firefly 0.3 Lumen - 20Lu - 280Lu - 800Lu - Turbo 1050Lu. When pressing the button ~ 1 sec., The strobe mode is activated which is automatically executed at the highest possible level and to pressing it again returns to the previously set light level. The TN 12 is a so-called "Memory Lamp". This means that the last set level is retained even after switching off or changing the battery / charging the battery. While the battery in the lamp, the higher levels are no longer discharges Switchable because the driver electronics is no longer enough voltage available over time. This is not a bug, but a protection. If you go to the middle stage (280Lu) has arrived and it now and then blinks twice, it is advisable to replace the battery or tolerated him to store LiOn batteries no deep discharging and as the lamp does not know whether to use a protected or unprotected battery, this should be a safety mechanism to the battery is not to kill. The highest level (Turbo) should also acc. To instructions no longer than 10 min. To be used at a time because the lamp head in this performance is very hot. In conclusion the TN12 2014 very thoughtful, superbly finished torch is heard in spite of their small dimensions to the "light beating". Mir makes it fun and beautiful thanks Gürtelholster it is always there and it's fun to amaze skeptical contemporaries who believe such a small thing does not help. :-)
