Where did you get this? It appears to be another Sipik 73 clone. I already saw an add. for a UltraFire Sipik 73 clone. This looks closer to the Sipik. I have a Sipik 73 and like it, except the detail appearance could be more to my liking. Very good design. Not much throw with the XM-L and small size, but great flood, uniform and a bit wider than either of my UltraFire Sipik 68 clones, and small size. Cooling seems good, in spite of the fins being on the head instead of on the body, because the head fits snugly on the body. Low mode is not very low.
