Yes. Just the standard Zener diode and R200 resistor.
Okay. Here’s my question, and it’s not a joke. I’m dead serious.
Can one of these drivers be modded to run 6 cells in series? Yes really. 6 cells in series with 12 emitters.
Ill leave that question to others.
But Im planning on running 6cells (2s3p) with 12 emitters (2s6p) from Zener modded FET driver.
Are we both looking to mod the same light?
I have ordered this:
That’s the one I’ve been planning on modding ever since you showed it to me. Looks like were building the same light. Hope you don’t mind. Are you going to keep the XM-Ls or go XM-L2? Lots of investment for twelve new emitters.
Cool! Go for it!
I have not decided between XM-L2s or XP-G2s.
The build will probably have to wait some time though. So you might beat me too it.
Dx has the xml2 version for a bit more.
I could probably use some advice on the way. I always find unexpected hurdles.
I’m ordering it now. I’ve had it bookmarked for ages and look at it every day. It was only a matter of time. I was originally trying to decide if I wanted the Hyperboost, but it has no modes. This light will get hot on high.
whoaa… nice mod, I was about to give up on my 9T6… I guess this will help me kick start my project again… thanks,
BTW is this FET driver was the one meant for building Mt-G2 light?
Yes. The same one.
I don’t know if I want to trust DX. It does say XM-L2, but they still have the stock XML pictures. I mean if they’re XM-L2 great.
Now I don’t know what to do.
I wonder if I can run that FET driver with 9 XP-G2 LEDs on noctigon? :bigsmile:
Nice! What firmware did you use on that FET driver?
man 10A whoah! Gotta be getting mighty warm on high
Excellent job!
absolutely!
Will be pushing ALOT of amps but if the XP-G2 can handle it…will make one HECK of a thrower !
I got the FET driver from RMM.
OOOohhh… my hand are itchy tonight… I got spare MT-G2 FET driver and sadly no XP-G2 on noctigon :_(
can you mix them LEDs? say 6 XM-L and 3 XP-G2? in the middle? is that even possible? 
I think Vf is different between the dies, would cause one set to pull more current than the other…don’t think they will work w/o one set of them getting way to hot and burning out
I’d probably take the chance for $1.30 difference. L2 in the link, title, desc, and specs. Worst comes to worst and they are XML you could probably file a ticket and get the difference back at least.
I really liked the light as soon as I saw it as a new arrival, but the price tag and my lack of 6 good cells to dedicate to it 
… Would love to see what you guys can do with it.
Does that link pull up in Spanish for anyone else?
I kept getting it in Spanish. I mucked about for awhile til I got the English site.
I ordered it there. There was a BLFDXDEAL coupon that gave me $4.50 off.
I had a bit of a scare. Light was getting sporadic when I turned it on. Thought the switch was going. Bridged the tail and was only getting faint modes, then nothing, then very faint lows only.
I went to pull the driver and noticed there was a tiny bit of play in the driver. I cranked down the retaining ring and all Is good.
I did a little tweaking on my light today. Braided the tailcap and got the reflector sitting down properly.
Three of the emitters, though not off center enough to notice, were off enough that the reflector was sitting on top of the raised part of the centering discs. This caused the bezel to not tighten properly and leave a gap. I removed the three offending discs and sanded the raised part flush. Since the other six were still intact, the reflector centered itself nicely and the bezel threads down tight.
I remembered I had some UCLp AR Acrylic Lenses for my COURUI that LinusHofmann brought up in his COURUI thread. https://budgetlightforum.com/t/-/23051?page=2#comment-509979 I had ordered two, and they sent me three...and they were the perfect fit for this light.
These are really nice lenses, and they come in large sizes from flashlight lens.com.
When you install them, it looks like air, like nothing is there, with a Light transmittance: 97%
If you hold it just right, you can see a pinkish tone from the AR coating.
Now that I've got everything just how I want it, this light definitely earned its clear bootcap award.
