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

SB - Great Job As Usual Sir!

I really appreciate that you tried different cell combinations, and, revealed what a difference each would make, that's really useful info.

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.
Same here. 20r work perfectly.
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).

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. :whistle:. I'll update the review when they arrive.

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!
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.

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.

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!

+1__________:)

I just gave him another donation. The reason I say this is because if I can do it, so can you. I am only working part time........and that may end. This is important as a whole and as "Teej" said to be able to test IMR batteries so we know their additional output when used in Vinhs lights! :thumbsup:

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!!!

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

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.

Some lights need even more than that.

:D

Notice that your 1 meter lux works out to a lower cd than your 4 meter lux reading...and, that relationship would continue, with the lux dropping but the cd rising until it represented the full range of the beam.

At that point, the cd would remain the same even as the distance increased and lux dropped as per the inverse square law.

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.

FYI, I do keep the older cells around for awhile afterwards, but just for doing the repeated beamshot photos. Given that I often take >20 lights with me when I head out for the outdoor shots (for the repeated comparisons), that's a lot of cells to pre-charge to 4.2V and load into each light ahead of time. After awhile though, they are off to the recycling center (with my typical bucket of spent primaries). I do get some funny looks when I drop those off. :rolleyes:

Thanks for the donation. :)

I'm limited by the "payment" form Paypal provides, but you can always put any special requests in the "shipping instructions" box. ;)

In any case, I always follow up every donation with an e-mail thank you, so that's another opportunity.

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.

Thanks TEEJ , i get it that i have to measure at greater distance to have a accurate test. But i want to know at what distance selfbuild measure to have the 122.000lux reading?
(Because my led is getting +-4 amps instead of 4.5 amps in the vinh modded s200c2)
Thanks Marc

Sorry, i was to late with my question, selfbuild already anserd.
Thanks

Update: just measured 1600 at 8meters (not more place here)= 102.000lux (getting there!!!)

It's like someone brought a laser to a blunderbuss fight.

I though the reason EagleTac elected to not offer a tailcap lockout was the high power. 10+ watts for the S200C2 / T200C2 when in TurboBoost, and there is potential for melted aluminum if there is marginal contact from a non-fully tightened cap/retention ring, etc.
Plus a more robust platform, if you want to prevent inadvertent activation, take out the cell(s).

My additional Samsung 20R cells arrived today, and none of them activate in my S200C2 without a magnet. This makes it pretty clear to me that the issue is the physical protection feature on the contact disc in the head of the light. Depending on tolerances, your sample may or may not take these cells without modification.

I though the reason EagleTac elected to not offer a tailcap lockout was the high power.
Well, the G25C2 Mark I had anodized threads, and the Mark II version did not (without much difference in the circuit).

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.

As including a contact disk would not fit into the cost cutting paradigm, the Sure solution would be patent related.

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?

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.

I would agree though that IMR/INR are probably a good idea for the XM-L2 Vinh version (assuming it is driven harder than stock).

Somewhere between 20,000 & 137,000 lux? You're probably not wrong there! :crackup:

Thanks for such a great review. I was trying to decide where to start with a modified light and this really helped me a lot. I am a fan of smaller high output lights and this certainly seems like a powerhouse in a nice little package. Is there a preferred IMR mAh rating to get the most out of this type of mod? Thanks again for your great reviews.
