First of all, I was pleasantly surprised when I, contrary to the title of the product description, but the latest model of lamp erhielt.2013er Model = 3500 lumens and the current 2014er model has 3800 lumens max. The lamp has a luminosity ... disgusting! I know what I'm talking because I have a few other "searchlights" at home (Xeray 75W, Polarion PH50 + PH40, Microfire Warrior 35W, Olight Marauder X5 ... etc.) It's just brutal as with something small such an amount can be generated to light! One major reason for this purchase was the one the opportunity to können.Das load the 18650 batteries (4 pcs required) directly in the device out and reingefummele is annoying in the long run in so many other products! Then the possibility in an emergency lamp to betreiben.Es with only one or two 18650 but is strongly discouraged in the manual ... "Only in an emergency!". And then would be the super practical OLED display for voltage, maturity (very handy!), selected mode, Lumen Output. Temperature modes. Overall, the lamp has 8 Modi.5 "normal" and special modes 3 = Strobe, SOS, and Beacon. Although I would imagine that would be handy Beacon night scene of an accident to identify (Beacon = position light) .Hierbei the lamp blinks at 1-second intervals as a flash tube. It is at the beginning a bit confusing how to reach the entire modes and umschaltet.Aber careful reading of only two sides (including more?) Comprehensive instructions quickly creates Klarheit.Sehr practically also the fact that if in an emergency situation as much light as possible (turbo mode) needs, you do not only have to press cumbersome through the modes: On any normal light level twice more firmly press the dial or in standby mode once the button a little harder drücken.Sehr thoughtfully. For Turbo Mode is not to say that upon reaching 60 ° of the output of the lamp to the next lower level lowers ... Überhitzungsschutz.Wobei 60 degrees without gloves can be quite warm. Another thing about the battery: It is expressly warned (also available on the lamp itself) to use unprotected batteries. They have no protection against overload, deep discharge, overheating ... etc.Soll yes so many already be quite evil explode if mistreated! So, I think that's enough time ^^ My conclusion: The price is gerechtfertigt.Absolue by equipping, luminosity and workmanship buy recommendation!
