Was looking for a compact and lightweight as possible lamp. This is to be used both as a head lamp or as a backup lamp. The lamp does not only look at the photo look good, but it is top handles. It comes in a well-made, padded case with zipper + flood reflectors + wrist strap and a tube of silicone for the care of the O-ring. It works in the real world smaller and more compact than I expected it (which I find good ;-). Have them fitted with 6 AA batteries Enelope XX. Lights she does ;-)) The correct test is of course only in the water. On Dec. 27. It goes by plane to dive. Hope that I can then only positive things.
