I read this thread and couldn't help but run out and buy one. My local Target in Hillsboro, OR only had this one in stock. So far I am very happy with it as build quality seems good and it is decently bright with better throw then expected. My only complaint at this point was brought up by another poster - the switch is a "hair trigger" and protrudes from the end cap. It would be very easy for it to come on temporarily when in pocket, etc. I got a little crazy and took some pictures, beamshots and meter readings. Here is what I've done:
A size comparison with Nitecore D10, Energizer, Ultrafire C3 (DX), Ese LZ2
From the front, same order
I forgot to include my Rock River 1xAA but did include it for beamshots. All flashlights using fresh Eneloops. Here they are:
Argh, I forgot to lock the white balance on my beamshots - very sorry. Exposure is the same though.
Energizer left, Rock River 1xAA right (sorry, white balance different on this shot then others)
Energizer left, Nitecore D10 right
Energizer left, Ultrafire C3 right
Energizer left, Ese LZ2 right
Last but not least I measured peak throw from 1 meter using my cheapo LX1010B:
Energizer 1W 1460 lux
Nitecore D10 (max) 1398 lux
Ultrafire C3 585 lux
Ese LZ2 (max) 1075 lux
Rock River 1xAA 656 lux
These readings were taken from the brightest point of the beam. I find my meter to be very consistent but readings are often slightly lower then I find from other forum members using the same flashlight. In overall brightness the D10 and Ese are clearly a notch over the others. The Energizer is out-throwing all of them though. It puts out quite a tight hotspot.
Last thing I would mention is that I found current readings to be the same between the Energizer and Rock River. Both read .73A at the tailcap with a fresh Eneloop. I think they are probably putting out about the same amount of light but the tints are very different. My Rock River is downright violet in color while the Energizer is quite nice. Kind of a yellow hue with a slight blue tinge.
Hope this helps!
