This is an awesome mod. Too bad I don't like the design of the s200cs.

I agree. Mine has run flawlessy on Sony VTC5's and Samsung 20R's. No extenders or mod required, and much brighter then most protected cells.
I only have two Samsung 20R cells at the moment - and both require one rare earth magnet to work. In one case, I was getting intermittent contact issues, so I doubled-up on that one. I can only assume there is some variability here in the size or depth of the positive contact of the cell, or on the plastic disc in the head of the S200C2 (i.e., mine has a slight plastic lip, so I can see why the wide button of the 20R is right at the limit of what may work).Same here. 20r work perfectly.
I've order a set of PFs as well (with small button top), so we'll see how they do. Given the speed of mail these days, it will likely be a month before they get here.I have NCR 18650PF 2900mAh [Flat tops] and they work. They do have a small button for a flat top. I was not sure they would work so I bought NCR 18650PF 2900mAh Button tops!! Needless to say they work!
Yes, this one case where it makes a big difference. I don't normally report on IMR cells, since the difference in most lights is marginal. Once I get the remaining 20Rs in, I'll give them a try in the TK61vn as well, just to compare.I really appreciate that you tried different cell combinations, and, revealed what a difference each would make, that's really useful info.

I have another four 20R cells en route to me. Should be here any day now, which will help settle where the source of variability is (I'm guessing it's in the head). If so, an exacto knife would remedy that problem. . I'll update the review when they arrive.

Well, it IS nice to see that the $ sent to your battery fund is being put to great use!
For any one who has NOT donated to SB's fund, THIS is an example of WHY that's a great idea!

Hello, i am also working on a dedomed xpg2 S200C2 with modded circuitboard , and with the help of VINH i mannaged to have 5700lux at 4meter = +-92.000lux at 1meter.
Only tested on a protected cell. Waiting for a IMR.
I only want to know i you (selbuild) measure at 1 meter or further, because at 1 meter i only have +-70.000lux?
Thanks Marc
Indeed, just my battery purchases are extensive (especially for rechargeables). To maintain consistency, for output/runtime testing I typically discard cells between ~40-50 cycles (or ~6 months, whichever comes first). For my core AW 18650s, I have typically been going through >25 cells a year (although that number is starting to go up significantly with all the multi-cell lights I've been doing). When you throw in NiMH, primaries, high drain cells, etc., it does add up quickly. And of course, replacement equipment, licenses, etc.Well, it IS nice to see that the $ sent to your battery fund is being put to great use!

Thanks for the donation.I just gave him another donation. ... I wanted to leave a message w/ payment but was not able to!!
The message to SB would be that there are conditions for this donation!!! This will be for IMR batteries for upcoming Vinh lights to be tested!!!

Yes, all my beam measures are done under ANSI testing conditions, which is 10m. For a light like the S200C2vn, anything less will definitely give you invalid (and low) measures.You need to measure from further away to get a more representative number....as at closer ranges, the beam is not fully formed on many strong throwers. The ANSI spec is at 10 meters for example.
Well, the G25C2 Mark I had anodized threads, and the Mark II version did not (without much difference in the circuit).I though the reason EagleTac elected to not offer a tailcap lockout was the high power.
Well, if it isn't because of _ure_ire's overly grandiose patent claim, then I guess it can be thought of as cost cutting, and/or an attempt at upselling.
Hard to say (in part for the reason you point out - I don't know if there is a drive level difference). It's bound to be somewhere between my dedomed XP-G2 and my stock G25C2/TX25C2 with XM-L2 - but where exactly in-between I can't say.Selfbuilt any guess as to how much lumens and lux his dedomed XML2 might produce comparatively?
Does anyone know if Vinh drives the XML2 harder than the XPG2? (ie more amps albeit possibly a lower % driven over reccomended drive level?)
If so, am I correct in assuming that would make using IMR/INR batteries more important for maximum performance?
