Should there be some allowance in the equation for the Zener diode?

Sorry, I don't understand the question.
You have a linear driver. Input amps is the same as output amps.
This is just like a single cell light running a FET driver. Only that you have 3 batteries in series, and therefore also need to have 3 emitters in series.
The Zener is basically there in order to fix the input voltage to the MCU, because the MCU is not built for 12V input, so the Zener takes care of that bit, as far as I know. (Im not much into the technicalities of the zener mod, I just know it works.)
I don't think many have done these mods with 12v input yet. Only heard RMM mention it. Is it the same zener diode as used on the regular (2 cell in series) zener mods?
If cells are in parallel, you can just wire all emitters in parallel. Otherwise, not so easy..
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.
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.
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?
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.
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.
… Would love to see what you guys can do with it.
