The lamp is extremely bright and really to be regulated even in 5 stages. The 2 red LEDs can be separately switch either on a permanent or flashing mode. Apparently should not affect night vision when in the dark for a short time needs the light. The 5 stages of the white LEDs are very well matched and also really useful the Different personalized management adaptable. The weight is in my opinion very acceptable, it falls not adversely affect the wear and the tapes can be very quickly adapted to the head shape. It wiggles hardly at work and short jumps. The workmanship is on a very high level, the threads of the battery compartment has a lubricated rubber gasket. The water tightness I have not checked, but the lamp does definitely a dense "impression". As a very nice additional function flashes when you insert the battery, a green / red light on the switch according to the charge level (eg 4 times flash - pause - 2 times flashing corresponds to 4.2V) The lamp can also be removed from the holder.
