the madness! :) 9

positive:
- The brightness, there really is not an ordinary lamp afterwards!
- The size, not too small and playful, no, really perfect in my opinion!
- The focus, I was really skeptical when I read it the manufacturer, but am surprised that (without "holes" in the light) is it really as good and accurate!
- I can to life of the batteries / batteries not comment because no consumption / change notice in a few days could

negative (here I am afraid to be a little more detail;)):

What I find extremely annoying the switch.
Quasi there are 2 "primary" positions that you can switch:
Press 1x: light = dark
Press 2x: light = light (100% according to the manufacturer)

now one has however (which extremely annoys me personally) between each switching cycle a kind second assignment with inserted. ie every time when the pressure switch lightly pressed (such as when focusing on a digital camera) gets you 130% (according to the manufacturer specification!) of light. Although this is in itself a very great thing only would you look at that also can completely save in my opinion and it only "1x = dark, 2x = light" to leave. Me personally it bothers extreme if I every time "verblitzdingst" if I'll only need a short time dark light. But nagut, you can also simply hold the lamp while against the jacket then adjusts the already;)

All in all I'm really impressed that (okay a CREE) LED to such an enormous power is capable of! Still, I'm not really sure whether the price is justified!
