I received the D25LC2 XML clicky over the weekend along with a Jetbeam Intellicharger i4 and an Eagletac 3100mah battery. This is my first "real" flashlight (well... larger than AAA anyway

) so I'm not really qualified to do a full review. My thoughts are pretty much the same as zenbeam stated in his review anyhow. I really like the 18650 form factor; it seems to be well-balanced in terms of size, current, capacity, and rechargeability.
One problem I'm having is that the light randomly refuses to turn on. It happens only once or twice a day (once today so far). When this happens the light won't operate at all until I unscrew one of the ends and completely remove contact with the battery. At this point the flashlight operates normally.
I have only one battery at the moment, so I'm unable to rule the battery out as the cause. The positive contact was a little messy (as zenbeam stated) and I just now cleaned it... don't know if or why that possibly would have been the issue. Anyone have any ideas? Seen this behavior before?
I love the light, output is incredible! I do wish it had a lower low mode. Moonlight mode is somewhat of a joke; barely discernable from the regular low, but that's what other lights are for
