Fenix TK35UE V2.0 Tactical Flashlight soldier helmet
I'm looking for any comments on whether or not the Fenix TK35UE V2.0 could possibly/realistically be mountable to a soldier's helmet, and if so, any logistical recommendations would be appreciated. Or, is this a silly question in that headlamps for soldiers are more typically used for general... -

The just-new Fenix BC30 V2.0 bike light
I've been reading a number of reviews of this light from various places and there seems to be a downside to the upgrade in that now that the 18650s are easier to remove from the new holder, the light turns off at the most inopportune times such as when going over bumps or uneven ground. I...- DougL

Nitecore EA4 (XM-L U2, 4xAA) Review: RUNTIMES, BEAMSHOTS, VIDEO and more!
Speaking of emergency use, I think it's very important to know approximately what can be expected as far as emergency mode run times in a light that is being put in the role of one's emergency flashlight; I would consider the sos and beacon modes to be this light's emergency modes...- DougL

Olight M20 R5 Vs. M20 S2
I know this is an old thread, but maybe someone who knows the answer will see it and chime in. Is the S2 really 600 hours (give or take) on low and twice the run time on medium compared to the R5? When I contacted Olight about a year ago with this question, believe it or not, they actually...- DougL

Fenix TK12 18650 tube on a 4Sevens Quark 123 Turbo X. Does it fit/work?
The title says it all. I know that the 18650 tube for the Quark is well nigh impossible to find as it was a very limited run. Does anybody know if the Fenix 18650 tube for the TK12 would fit on the Quark to enable 18650 compatibility? Thanks, Doug- DougL

Hot batteries in Fenix TK40
Any idea why Fenix specifically recommends that we not use the lithium primaries? Is there any danger of anything, including reverse charging when they get low in charge? Any precautions I need to take aside from taking them all from the same 8 pack, such as perhaps when the highest level, or...- DougL

Hot batteries in Fenix TK40
I know this is an old thread, but I just picked up a TK40 recently, and I'm concerned about the last comments made by was.lost.... Does this mean we should not use the Energizer Ultimate lithium cells in the TK40 as it will void the built in reverse polarity protection of the circuitry...- DougL

Poll: Do You Use Strobe/SOS Modes?
Early last month I started a thread on this forum/site purely related to beacon mode, its optimal frequency, and the uses people have for that mode. Buds224: You were one of only two other posters in that thread. You and I both seem to like the versatility of the Fenix TA21 in general and in...- DougL

Beacon Mode
I'm interested in people's opinions of the most useful frequencies for beacon mode, what purpose they use for this beacon and which lights (currently produced or discontinued) are best for this use. Right now I'm thinking most practical uses are as an actual beacon for a campsite or boat launch...- DougL

Warning do not carry exposed batteries in your pocket.
I keep my spare batteries in one of two cases: a) pharmacy pill containers; these come in various lengths and diameters so you can fit various types of cells in them from single 18650 to multiple aaa and aa combinations, and b) blood test strip containers with the attached flip top lid which are...- DougL

Dangerous explosion with 2 CR123A primary
Given Helmut.G's comment that, "Oh and since checking on batteries with a voltmeter or multimeter was mentioned several times, everybody please be aware that the resting voltage of a CR123 primary battery doesn't tell you much, if anything. It's only true for Li-Ion rechargeable batteries that...- DougL
