Convoy L6... XHP70 Beast!

Well, JasonWW was right it seems my led was in backwards.

I just installed a new TA driver with Narsil, and kept the wires reversed……it works!!! (Thanks Lexel & Texas Ace).

This is huge, big deal for me, as it was my first real mod, with my extreme lack of soldering skills. It ain’t pretty, but it is functional. Now to figure out how to keep the ramping going in the same direction.

A single cell won’t deliver max power through an XP-G2 due to high forward voltage. Using 2 cells with a Buck driver allows 5.5A or more, which one cell alone simply can’t reach.

Etex, pause for about 2 seconds, maybe a second a half, the ramping will continue in the direction you were going before.

Or if you don’t wish to wait, quickly hit button to reverse then release and do it again and you’ll be going “forward” again.

Congrats!

You’ve got the bug now, won’t be your last.

Thanks Dale, that works consistantly now, guess I was being a little to quick on the trigger.

This ramping is soooo coool!

If I’m one to presume, it’d likely be a difference similar to the one between the M1 and the M2: not much, but it’d be floodier.

Now on the note of beams, if we could get an L2 with the same beam profile of the L6, I’d be one very happy flashaholic :smiley:

Thanks, Dale (you posting fiend!). I’ve never really messed around with buck drivers, still a lot to learn there.

Thanks, I did happen to buy 2 of those drivers….so I’ll get to do it again. I may have to get a new Iron, the old Weller 3202b seems to be inconsistant.

PM inbound regarding soldering iron…

I love reading all of this, but I do have one question…

Does everyone know that there is a thread entirely dedicated to modding the L2 and L6? HERE IT IS!

I don’t think that I can un-derail a BLF thread :smiley:

That is beyond my level of influence but I do have to try once in a while!

The main reason I bring this up is that if I were searching for how to mod my L6 or L2 and I were either not a BLF member (ridiculous, I know) or a BLF member who was not as obsessed with this madness as I and most of you are then I would probably look at the modding thread where sadly, I would miss much of this excellent discussion.

Sadly, the modding thread only has a fraction of what is being posted in the main L6 thread. :weary:

So if any of you want to head over there please do! :wink:

The pic in the OP of that thread BTW is a mash-up combo of L2 and L6 modded and stock (the modded version a DB custom) and topped off with a knife customized by our late and great modding mentor and very missed friend, Old Lumens. RIP brother…

It’s just that this thread is seriously notorious… Hey J-Dub, how about you put a description of the mod thread front page first post on top with a link? More people will see it instantly (hopefully) and use it… Just an idea. :slight_smile:

My bad, I’ll do better. The reverse wires were an anomally, but still only relevant for modding.

Thanks

That’s why i want to build the single cell version , for comparison and because it will be a cool thrower .

I have seen very good results from single cell powered xp-g2 S4 emmitters , and i would really like to know the outcome on this too .

Sorry Jdub:)

Ha! Not bad advice coming from a “noob” :wink:
Done. Thank you. :+1:

The spring bypass at the tail end of my L6 has broken off (at the lower end of spring). Looks a bit tricky to re-attach (my soldering skills are limited). How much lumen loss do you think I would be getting by not having the tail spring bypassed?

Probably most critical if your L6 is bumped in power. If stock, the output difference won’t be all that noticeable. If bumped, your spring could collapse under the load, which is the real reason for the spring bypass in the first place.
It’s not difficult to solder a wire in, try to wrap the bare wire over the top coil of the spring before applying solder, this helps it stay together better.

Hi,
My L6 is stock, so I’m not sure if it is worth re-soldering. I’ve not noticed any visual change in output. Still, might give it a try based on your advice.
Regards,
Stephen

Cheers buddy! :slight_smile:

However… I actually meant really on top of first post. Now, one needs to scroll down the first post all the way to read this message. If you put the message all the way on the top, then it’s more likely that people will get to read it, instead of clicking directly to last post and not reading it…
… And you could also post the latest news (tan/sand colour L6, or illuminated switch) right below this message, so it’s easier for people to spot it, again, instead of scrolling all the way down first post to read latest developments. Cheers again!

In terms of difference in output, the absence of a spring bypass is I think primarily of interest with a FET drive, where you want as much voltage as possible to the led (and as little voltage consumed by other components, such as the spring). The L6 has a constant current driver, so I don’t think you’re going to have much of a difference in output at all, let alone visual difference. It’s primarily a slight reduction in run-time, but I guess it’s pretty marginal. As Dale mentioned, there is a difference whether the L6 is stock or not. In stock, there is 5A going through the batteries, hence 5A through the spring. This is not a stupid high value. If you have 10A going through the batteries and spring, then a doubling in amps means quadruple in losses. This is where things get nasty. But in stock 5A form, it’s not really too big of a problem I think.
