Very good can also be used as a helmet lamp

Have decided to use the longer variant with two AA batteries. Has more lumens, that was the reason.
The lamp is very good to use even the individual graduations I think succeeded. More flashlight really need no man. I have recently made me also with two cable ties on the helmet - top illumination and especially no Kabelgewurstel as other helmet lamps where the batteries must be transported separately from the lamp. Through the two easily accessible operating buttons also at the helm well set. The times specified by the manufacturer also cut out about which processing is really great.
Only negatives: the tube for the batteries or accumulators is mE little too far in diameter, making the batteries when jerky movements around a bit in them rattle, rattle which is certainly exaggerated and I do not think that what is happening. Here one would have to work a bit more precise, but this is whining at a high level.
Furthermore, the state function is a little too shaky as is given only on the half of the area of ​​contact with the ground. Due to the criticisms only four stars.
