Tom i havent found a soutable method of dedoming clearly V6 0D, tried everything though – i mentioned this issue like 10 times here so far, but it seems you all missed it…i tried like 20 + emitters, both electricaly and chemicaly

V6 1A on the other hand is quite a different story

Mouser also offers V6 from the E1 kit, they are great emitters and dedome pretty fine

About the LE1 thing- its the way Cree supplies big destributors you know- a whole kit, i allready bought from those and they are exacly like those S4 1D that i bought several months ago from Cutter Aus

About those new S5 emitters- they cant be dedomed, at least i cant, the p coat is too fragile ….from 20pcs i managed to get 1-2 good ones, even so the core is bigger and results arent good- its better to use V6

I would never suggest for ppl to order kits like 50, 51,k50 or k51: go for E1-2-3 only: i already got ME2 and ME3 and they are cheap and good

Thanks Mitko! I know there was mentioning of new XPL dedoming problems, but could not recall it was limited to 0D's - sorry bout that. I really haven't been doing dedoming much, and don't have a great memory, and didn't think of searching for it. Just been too busy on firmware, reviews, ATtiny85 projects, etc..

Good to know bout XPL V6 1A's (E1 kit) - definite way to go then. I'll still try the 0D I got mostly dedomed because it looks pretty good. If doesn't perform or look well in the beam, I'll go with a 1A dedomed.

 

Just found this post by MEM: http://budgetlightforum.com/comment/954303#comment-954303, in this thread: http://budgetlightforum.com/node/47139.

He's dedoming XPL V6 0D's and XP-G3's? Yikes, wonder how? But MEM has a few tricks for sure...

Well m8 , i also got 2-3 good dedomed G3s yet S4 outperform them: even the new ones, just ask yourself, why then he offers those modded M3X with XPG2 but not with XPG3? Actualy M3x XPG2 modded should give like above 420k mcds, i have several of those modded too/ emitters running at M3X driver default( 4.5amps) /

By the way, a good XPG2 modded and well centered M2x gives above 350mcds

For the V6, so far i have tested V6 1A( both IOS and KD breeds), V6( various bins) from Mouser, a localy found V6 E1 kit and E2 too: only V6 0D and those V6 E2 gave me those dedoming issues…maybe a sigle batch issue, who knows

The tint i do prefer is warmer but thats another topic

The other interesting found of mine is the fact that V5 would never tops 6 amps( usualy running at 5.2-3 tops) yet V6 reaches it fairly easy with a good fet and VTC5A.

I also tested V5 and V6 top amps , with my own fet drivers (using sir800dp fet) , v5 topped at 5.3 amps and V6 at 6 .

Never tried dedoming xp-g3, because i don’t think it really matters …

I also can confirm on low Vf V6’s, i have seen few 3D’s pull 5.8-6A from 25R measured at the tail, might be slightly lower at the emitter but those are very good numbers.

 Olight i3s, Olight S1, Olight S Mini, JetBeam Jet-1, BLF 348, Astrolux S41S, UF SK-98, Convoy S2+ 3*XP-G2, Convoy S2+ 3*XPL, Convoy S2+ 219CT, Convoy M1, Convoy C8, Brinyte B158, Courui D01, Convoy L6, Noctigon M43

Yea, not sure what MEM was think'n of, or his results of the de-domed XP-G3 exactly. He's checked out for a while now - hoping he comes back. Haven't followed the M3X stuff - wasn't interested in yet another 63 mm head 2 cell or 1 cell thrower, and not cheap as well, plus it's Olight - not my favorite manufacturer.

For throwers for now, my interest lies in something small and pocketable, or really big.

Indeed Tom, and here comes our lovely C8 host , good old S4 2b and the fet driver- if you get lucky: 200k, Uniquefire C8 has a very nice reflector you know

Why not X6? With your A85 driver mine gives 115k mcds, quite pocketable too

Speaking of Olight M22 warrior can still be found at a very reasonable price, its design is quite good plus it could top 90k mcds with a V6 emitter and a fet dd driver

The new UF 1508( the 75mm head) is a great big thrower too, i was able to get 480k mcds out of one( again V6 modded)…sadly those days dont have the time to try the XPG2 version out

Your A85 drivers and firmwares are lovely btw, keep the good work going! Beer

Thanks! Yea, I got great #'s from the 1504 (big head one) with the good S4 2B, think it was 540 kcd, at least. It's a true light saber - love it! Also got a 2nd one in green, and spare pill with red - both outstanding.

Dunno where the best deal is on the 75 mm 1508. See a few listing on AliExpress. Maybe this one for $53: http://www.aliexpress.com/item/UniqueFire-1508-T75-xm-l2. Little pricey...

So… i ordered 20 pcs from those S4 binned Moser breeds…and they came out from the old stock…quite a surprice Smile

Yet, the suprice wasnt just one – instead of S4 1A or 1D they are something like S4 2C/ or at least very colse to those S4 2C that i got from Cutter earlier this year, i saw this the moment i powered one for a hot dedoming

The tint after dedoming is clearly warm with a nice greenish addon ! Great for hunting, and no that great for your BLF taste

4 pcs are already dedomed and tested, they all pass 4amps easy

The bad thing is that one cant trust Mouser binning and labeling too

No offense, but I’d personally trust mouser labeling more than cree binning

Mitko you could start small business selling us leftovers of old S4 emitters?
You are lucky(or knowledgeable) in getting what you want. I don’t have luck… You got good old S4 from Cutter for example while I got crappy new one.

I gave up on searching them.

If you want i can share some of those Mouser XPG2 m8( have 14 pcs atm, will order more), but you can buy them yourself- when i saw them the reet was full, now it has 980 pcs

its highly unlikely if they send you something different if you order that “wanna be” LE1 bin

I aint saying they are bad- vise versa: C8 mad eon a fly went with 162k cds with no AR glass and no tail spring bypass: and it wasnt that 100% focused you know, i tested it with not fully charger old 25r battery
A Clean 20% gain from the best S4s atm
i will order more of them cause they are the best atm, its just they are not LE1 but more or less E2 or something, even with the dome on you can clearly see the difference

The tint aitn that bad( for ppls taste) actualy, its looking EXACLY as Olight M3x default emitter`s tint

S4 2B are to be kept for special occasions only Smile

I would also like to order a few, but I don’t understand the mouser cataloque yet – how/where can I find them there?

My 2 cents regarding best throwing LED for single cell lights:

XP-L V6 1A dedomed in Convoy L2 (single cell) with fresh Liitokala 5200 and FET+1: 280,000 Cd.
New production XP-G2 S4 2B dedomed in same host with same cell and driver: 290,000 Cd.
Not much of a difference.

But – the XP-L pulls 6 Amperes and the XP-G2 only 3.7 Amperes …

Seems like new production S4 2B is better choice then V6 1A cause it smokes less current and therefore longer battery life for fet drivers. With buck drivers it could be opposite.

on the contrary, I was pretty fond of the XP-G2 S3 3D stash of intl-outdoor, because of the (dedomed) good throw and still good tint, and recently I ordered a few extra and I received them now labeled ‘S4’ on the package (normally we are happy with a bin-upgrade Facepalm ) and on inspection they are new type!

Very unlucky Djozz…

There must be more of them around. Probably in China market and it seems that we have only few China forum members here that could check that out.

I doubt that on the China market they have the highest bins S2-S4, most probably are not with known bin at all (tint or output). Hank was pretty good in getting specific high bins, some even exclusive.

They don’t necessary have to be S4…
S3 is also fine or even S2 is fine… Even R5 is better than new production XP-G2.

I am very lucky to have few good old XP-G2 S3 2B from Taobao thanks to our forum member wkhchin81 but I am running out of them…

He also tried to contact China market dealers and says that plenty of sellers are not familiar with such issue and the few sellers that are aware of problem say that their stock is first in first out…

I’m gonna buy some XP-G3s and compare them to my old XP-G2s, see how they perform at 6A.

Very well probably, the point is: how do they perform when they are dedomed?

I can’t remember if it was you or someone else who tried dedoming it and it didn’t perform anywhere near as good as an XP-G2?
I will do a test with dome on, then a test with shaved dome, and finally if both methods perform worse then I will try dedoming.
I will be comparing to a dedomed XP-G2 and dedomed XL-L2 and XP-L HI.
I think with dome on or shaved dome the XP-G3 should be able to have higher intensity than dedomed XP-G2 simply due to higher lumens at the same current.

I don’t know about the higher intensity, the footprint of the old XP-G2 S4 2B is smaller than that of the XP-G3 so the intensity shouldn’t improve…theoretically.

Guys I did my redneck tests with my diy Djozz style FET drivers and imho XP-G3 sucks! I would toss them in trash any time and anywhere… Evil

Maybe you’ll be better luck with buck drivers. I support professional testing although Djozz, MEM and FMC already did some preliminary tests of G3.

Now that the old XP-G2 is impossible to find, should we start focusing on Osram leds? A while back FMC dedomed one and was able to get 410kcd out of a Courui D01 (as opposed to 440kcd with old style XP-G2 S4 2B.)

That’s only a 7% difference in performance. Much better than the 39% difference between new and old XP-G2.

Pretty sure it’s the exact same size as these larger “new” xp-g2s.

I’m guessing the answer is they don’t know what they are selling, but fasttech has 2 listings for bare XP-G2 S2 0D, with different sku’s and also 2 different listings for bare XP-G2 S2 1A.
