Weight Approx 113g including batteries. Wears comfortable. Light downward with nice solid Rastermechnismus adjustable (better than the soft mechanism of many to be found, anscheinenden1W cheap copy (variant) (?) Of this China lamp, which is supplied only with gray headband without Cree embroidery). Large, much brighter LED (for comparison with the small LED 1W about my cheap copy). SOS function! (Has the low-copy may not). Battery smoother to open, at the low-copy Cancel the Hold Assen is virtually inevitable. Value for money phenomenal. About water resistance, power consumption and durability I can not comment.
