Hopefully one “apology” will do it. Beer
Big Smile I’m happy to say I’ve never left a wounded deer to wander the woods. I’d feel quite bad if one “apology didn’t do it. I love and respect animals and would never want one to suffer. Unfortunately for the deer they’re just too delicious! I don’t hunt for sport. I’m very selective of what deer to take and choose my shots carefully. Typically they topple over and that’s that. Thumbs Up

Sounds as though you do it the right way J-Dub… there is a lot to be said for that. Thumbs Up
I too strive for the “topple over” result when I have the opportunity to “apologize” to a deer… or anything else for that matter. Wink
Seems here regular “apology season” to deer begins 19 November. Looking forward to it…. Wink
Probably pack in my L6 in addition to a Convoy M1 should the need arise for a big light. <:——— that was the light content of the post. Wink
Good luck on the 15th.

Seems like a lot of Dove hunters around these parts don’t follow y’alls “one apology” rule. And since we have a daily limit, I really can’t imagine just why these guys are expending so many shells! (Well, yeah, I can, but really? I mean, if it takes a box of shells to get the limit maybe they should just be buying Cornish Game hens at the market or something.)

Interesting. I’ve always been disappointed with the XHP50, to the point that I’m determined to never use one again. I have a triple XHP-50 that I had high hopes for, but that is easily beaten by a single XHP70.

My L2 is getting an XP-L HI, not matter what. But I just grabbed an XP-L JM30, and was planning on doing either MT-G2 or XHP70 in it.


Yep, I felt the same way about the XHP50 and I’ll probably never do another one, but the whole build went off with out a hitch, which rarely happens, well maybe a couple times?

I really wasn’t expecting much, it was there, and I was waiting on de-doming a XPL V6 in racing fuel, so I threw it in, but when I turned it on, it was the best I have done with them, so I kept it that way,which in itself another rarity!

The L2 XHP50 has the same little yellow dot in the hot spot, just like I have in 8 of my KRONOS lights which are XPL-HI’s which didn’t bother me a bit.

For me the “one apology” rule does not apply to things that fly. And when it comes to Dove’s… I would usually be much better off monetarily buying “Cornish Game Hens” or a Rotisserie Chicken at WalMart…….. Facepalm .. Cash

No not yet, I had like 3 other builds (L2 SD75 and 2 T90-2’s ) while testing /blowing up drivers and LED’s going on Facepalm , I have to test the L6 with the XHP35 and smooth reflector when I get home in 15 day’s, ( I’ll have 10 days off) I’ll do them both and post up then. I have a few de-domed XHP-35-HD’s and XHP70’s I would like to directly swap out and see if they make a big enough difference also?

If you ask me Simon shouldnt gave the 1S L2 version up, now we are forced to buy 2s and mainly use it as a 1S: 2S is kinda bulky…plus we do have L6/S70 now
I have already builded L2 using XHP 35( D4 1A) and hornestly i aint impressed, it would never outthrow s good Dded V6 and it runs pretty hot too/draining batteries way faster
Ofc the lumen output is good

Not sure I’m following you there Mitko. The XHP-35 running at under 3A almost matches a de-domed XM-L2 U4 in the Shooter 2x at 4.5A while gaining over 50% again the lumens output. Sure, there are 4 cells to charge instead of 2, but run time should be longer on the 4 cells at 2.8A than 2 cells at 4.5A, right?

Out thrown by a slim margin, much more lumens and longer runtime. Impressive all around.

Enough so that one of the newest thrower lights from a manufacturer is using it to hit 600.75Kcd at 1550M throw. The L6 should come close to that with an XHP-35, haven’t done one yet but will soon.

The 1S battery tube of the L2 was indeed much to my liking.

Just not seeing the “runs pretty hot too/draining batteries way faster” aspect. Probably missed something somewhere…

Wow, I never heard or read about an XHP35 performing in throw close to what a dedomed U4 does. But 4.5A is kind of low for a dedomed U4 - I generally get ~5.5A out of them. In the stock Manker U21 w/XHP35 for example, I nearly doubled the kcd with a dedomed XPL V6 0D, running at 6A. But the stock Manker U21 is fairly low in LED amps, but draws about the same exact power from the cell.

I actualy ran it at 2.4amps( the XHP35) and it gave like 170k cds – thats what my driver is capable of
The heat on the other hand was quite a good ammount

At the same time the L2 V6 1A( at 5.8amps) build that i have here gives 280k cds and pretty good lumens too: a dedomed U3 0d( running at 5amps) is pretty close to that too..afaik 272k cds or smth

For some reason i aint saticfied with the results with U4 both 1C and 1A so i gave up on them

Yeah, i would order that light the moment it came out with a promo code Smile Imagine what will that reflector give with a V6 emitter…or S4 2B…

Btw, i do hope for Simon to solve that reflector problems of his for good , earlier that year i got several L2s with not so good reflectors

He’s been working on that issue for a long time. Trust me when I say that nobody is more frustrated by this than Simon and he is doing everything he can to make sure that doesn’t happen again. He’s not satisfied with the smooth L6 reflectors which is why they are not yet being sold. The prototypes are good by most accounts but not up to his standards so he is not selling them yet. Simon stands behind what he sells so if you received a few of the flawed L2 reflectors that slipped through you all you needed to do was let him know.

I had a bit of fun with my XHP-35 L2 tonight. Walking the trash down to the road I spotted a grey fox about 120 yds out. Shadow, my 100+lb Yellow Labrador, caught sight of him in the light and boy he took off like a cannon shot! He was huffin, scrunched down and really hauling it across the field. The fox turned and headed away but was like trotting. Shadow closed across the 100 yd section of field and was really closing fast. The fox started trotting a bit faster. At about 30 yds away, now some 200 yds from me, the fox shifted into Usain Bolt mode and ran off and left my poor yellow freighter like an F14 fighter jet! I laughed, and I swear the fox was laughing too! I saw the fox out to about 350 yds when he went into trees across the road and in the neighbors field. Shadow lost him at the bar ditch.

So, while the XHP-35 HD was lighting everything pretty well out to 300+ yds, I came in and opened it up then sliced the dome off. The 4 little half cells, 26350’s, are charging back up but I’ll get a glimpse of how it performs before I go to bed. 10:34PM Thursday night here as I type this. Wink

I’ll get lux and lumens measurments tomorrow.

I have an XP-L HI in an L6 that’s making 303Kcd… the sliced XHP-35 in my L2 is now making the same size hot spot as that L6 on the wall. This should prove interesting on the meter… Big Smile

Well, a bit of a disappointing surprise with the meter on the L2 XHP-35 sliced. “Only” 208.5Kcd at 913.24M with 2380.5 lumens. (“moon” is 16.25 lumens with the LD-2 modified for 4 cells)

I did gain throw, but the lumens loss is enough to make it hardly worthwhile.

All in all it’s still pretty wicked and the overall beam profile is much to my liking so I’ll call it a win, albeit by a smaller margin than I had hoped for… I’ll double check things and verify.

What was / is the reflector problem with the L2 ???

Hi all, I have a big problem, I modded my convoy l2 new, but something went wrong, after 1 hour the reflector of flashlight become Grey and lost the mirroring as the acid corrode the cromo… I don’t know why this happened, maybe the component of solder or solder paste corroded it… Now the problem is: do someone know if is possible to buy just the reflector without all flashlight? Or maybe someone have 1 reflector to sell me? Sorry for English and thank you for help

Did you use acid flux solder?

I would contact Simon at his AliExpress store and see about getting a new reflector…

I’m sure Shadow had fun ‘working,’ and I’m glad the two canines didn’t meet face to face.

I don’t know that for sure but it sounds likely. Someone else might chime in and confirm or deny…

Still, contact Simon through his Convoy site on AliExpress and get a new reflector.

Ok i contact him, 9€ and I can buy it, so the problem now is, how can I stop the corrosive effect? I don’t want to broke another reflector, could I clear contact with electric clear spray? Or do you have a better way? I have in my flashlight: driver Fet +1, xpl hi with noctigon and normal dissipating paste for CPU, then I used solder paste to solder driver and led, I think is this last paste the problem, but not 100% sure…

I’m not understanding why anything in the lights head would cause vapor once the light was reassembled. Seems odd to me, I would have bet everything, once cooled down, was neutral and wouldn’t do that to the vapor deposition of the reflector. But obviously something did, so yeah it’s pretty crucial to figure out just what caused it so you don’t do the same to the new reflector.

What is the brand and type of solder paste you used? And how did you go about soldering the driver and led… the reflector was nowhere near those when you were working, right?

Edit: Some solder pastes and flux core solders are no-clean while others demand being cleaned after application. Find out if you need to use an alcohol cleaner or a water based cleaner to clean up everything before reassembly. Wink

The reflector start to broken after 1h after I was using the flashlight,so I think something vapor went there with the hot… the conduct paste and solder past were economical, but the solder paste have the acid icon, I think depend by acid vapor because the mirroring was clear when I reassembled the flashlight, and it become Grey when was closed, I didn’t rub it…

Hmmmm, must have been the acid flux getting hot from running it. I haven’t been soldering for a long time, but I use the no-clean solder and top brand solder paste as well, Kester for both, and I don’t ever clean up. I’ve heard people talk about clean-up of the flux though, so this must be why.

Did your emitter get burned? Sometimes flux will splash on the silicone dome and then it burns when in use, this can smoke up the reflector as well.

Mmm I saw same paste on top of led silicon come to think of it, maybe it burned on top of led and did an acid smoke… Could be this one the problem? How can I clear the emitter good?
But the reflector is corroded, can this kind of smoke corrode the mirroring?

Oh yeah, that can do it for sure!

If I see any flux spatter on the dome I clean it with de-natured alcohol. Many use regular alcohol I think. I’ve even heard of people washing it with water, but … alcohol evaporates almost immediately. De-natured alcohol doesn’t leave a film, or that’s why I use it (could be wrong, don’t trust my memory! Get more feedback…)

Edit: To be honest, I’ve flicked off the spatter with a careful fingernail before. But man, I’ve killed a lot of emitters in a few hundred mods, I don’t sweat it anymore because I have so much stache it’s not a big deal… used to HATE having to order a new part and wait for it to get here! Now I have boxes and boxes of pieces parts of all kinds. Stuff I forget I have.

Oh, thank you very much for help man Big Smile I’ll clear the emitter tomorror and I’ll start to wait the reflector from aliexpress, yesterday I tried to clear the emitter with a fingernail, I’m lucky I didn’t broke it… Facepalm it’s like 3 months I’m modding and waiting for parts, all the times somethings went wrong: Fet driver 17mm and flashlight 20mm, spring oring adapter too much big, burned led because not noctigon, and now corroded reflector, I hope this will be the last problem… LOL

This is the emitter at the moment
