Hi,
Does anyone know what are the real modes & output levels are on the EagleTac D25A Ti Clicky? The manual says that in moonlight mode, the sequence is Moon > Low > Med; and in normal mode the sequence is Low > Med > High. However, I am able to visually discern a difference between modes that should be, in theory, exactly the same (e.g., step 1 in normal should be the same as step 2 in moonlight mode, but on mine it clearly is not). So it appears that there are really perhaps 6 or 7 completely independent levels.
The specs are not only wrong in that they omit the difference between modes as noted, but also because they only list 4 output levels (0.5, 9, 85, 141 ANSI lumens) when there should be at least 5 (moonlight, low, medium, high, turbo).
I've also noticed that Turbo is only very slightly brighter than High, although it's possible that it's quite a big jump in lumens, just not really very noticeable visually. Currently I'm just using the Duracell that came with it. Should I expect very different results with different chemistries?
Speaking of battery chemistries, is the EagleTac OK with all chemistries (Alkaline, Lithium Primary, NiMH, Eneloop, Li-Ion). I recently noticed that Titanium has a much lower thermal conductivity than Aluminium, which makes certain torches prone to overheating. I think it's OK on the basis that the spec says 14500 Li-Ion cells are OK, and those are probably capable of delivering higher current and voltage than any of the other chemistries, I believe, but I'm not 100% certain about that.
I don't care so much to know what the exact luminosity is, but it would be handy to have a better guide to the expected battery runtime at each level. The specs also don't mention which battery chemistry was used to obtain the results shown, but I believe if they supply a Duracell with the torch, then according to ANSI specs, that's what they should use for their testing. In any case, it would be useful to get either a rule of thumb or an accurate formula that can be used to convert between expected run-times for one chemistry under a given load to another. I don't know if such a formula exists or is even calculable, but an approximation would be more than adequate.
