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… 
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…
Yes I think I used an acid one… Was this the problem? :person_facepalming: Oh thank you very much, you could save my life… :person_facepalming:
“Yellow freighter,” I love it!
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.
I tried to write him, but when I click the simon’s contact, it show me there is a problem and I can’t write him yet…
Have you joined AliExpress as a member? I think they want you to be signed in to leave a message…
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. 
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 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… :person_facepalming: 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… :laughing:
This is the emitter at the moment
And THAT, my friend, is how you learn and get addicted!
Good luck!
You are in good company here friend. This forum is filled with a great variety of people from beginners with questions and lots of problems to advanced mad scientists (like Dale) who are happy to help beginners while dreaming up incredible new levels of flashlight technology and pushing boundaries.
Thank you for sharing your experience!
We all learn from each other here. That is the magic of BLF. 
Cheers!
