Lightbringer, I’m sure if you ask Simon when ordering you can get the 6*7135 you prefer. I think the C8 comes with a forward clicky, but you can also ask him to use one to make sure. With Bistro-Mini (or Biscotti) you can select mode 12 and forget about it. 100% all the time. The light will be coming with DTP, you will already have an AR lens, and you should be quite happy.

Simon loves flashlights like we do, ask him in the messaging screen before finalizing the order on AliExpress and he will get back to you, pretty sure he’ll fix the light up any way you like it and would probably even engage level 12 at 100% only for you so you would have it operating as you wish right out of the box. Wink

Simon is just really great that way. Big Smile

This new C8 foes have coated glass and DTP star and XPL hi right?
Just choose your mode in Biscotti and it seems like you have the light you want!

The BD01 and 06 are almost the same light with these differences:
BD01 comes with two rubber rings under the tail spring to slip over 18650 cell so that can be used instead of 26650.
The BD01 is bigger

Tube and tail of them Lego
the 06 is easier to pocket and a bit cheaper.
I like the looks of the 01 more but use them both (working on reviews so while doing that do a charge cycle twice a day and they both charge excellent)

The BD01 has a ~50mm head as compared to the BD06 having a 42mm head. The crenelations on the 01 are smooth, more gentle where the crenelations on the 06 are sharp and more pronounced.

I know the charging indicator lights through the reflector on the 01, don’t think it does on the 06. What I mean is, with the BD01 when the light is charging you see the illumination inside the reflector cup, it comes through a clear centering ring around the emitter. Looks really cool, I don’t think the BD06 has this feature but I’ve not seen the 06.

The BD01 I also know to have a 7135 regulated driver, easily bumped for more power. Wink While I THINK the 06 does as well, I haven’t seen that one.

Is it just me, or do the 7135’s on the spring side of the board seem to be closer to the center on the new driver?

I seem to recall soldering the drivers to the pill in the Convoy S-series (S2/S3/S6/etc) because the resistors got in the way of the retainer ring. I wonder if these drivers will allow the retainer ring to be used in the S-series pills? Does anybody have one that they can test?

Good eye ‘gchart’, and good question. Thumbs Up
I hope the retainer ring will work with these.

If everyone’s sure it’ll run forever at 2.8A w/o cooking the LED (DTP, integrated head, etc.), then I’ll take it on faith that it’ll work, and be happy with it. Big Smile

My only issue with AX is that, for whatever reason, it always redirects to it.aliexpress.com and everything comes out in italian. Hell if I know how to change that…

And yeah, I go and put “www” back instead of “it”, but same thing, still back to italian. ?!?

As for the light, I’d figure out the config, no worries. My only concern is that it cannot flip modes or even go into config by any kind of diddling with the switch. That’s why I might have to go and reflash it anyway or just hardwire the ’13 out of the way (ground/Vcc/NC the offending PWM-out pin, forgot which), which is a pain.

Wonder if I can just buy it in “kit” form… That way I can use the goodies in my black host and use the “clear” one as a regular light.

Feh, I always gotta make everything difficult…

The S2+ can be run at 2.8 A until the battery runs off without issues, but your hand may suffer a bit. I don’t believe that the bigger C8 could have worse thermal management than the S2+.
I can testify that apparently what was said about the S2+ is true.
I did it by accident one time with a fully charged 3400mAh Panasonic. No apparent damage to the S2+………
But that is another story. Wink

If AliExpress kicks you in a strange language I usually place the item in cart then click global site top right
Then gobto cart and click item to return and browse the shop or whatever.

Dang Dale I can test that cell status thing of the BD06 I got it here.
Give me a few hours and I’ll post a pic.

Hey all. I don’t have time right now to respond to everything but as far as the naming goes it doesn’t all make sense to me either. Some of these names and designs are “publicly available designs” meaning essentially they’re open source. Anyone can build a C8 and call it a C8 but some companies (like Convoy) do it better than others. In these publicly available designs they may be required to use the original name but I’m just guessing.

The BD series lights to the best of my knowledge were originally made and solder under the Dipper brand name but Convoy now manufactures most of them. I don’t know what the exact rules are but take the BD04 for example. It’s made by Convoy but it’s also sold by Thorfire under the same name and neither company is doing anything illegal in doing so. Convoy does use some of these public designs and does a very good job of them.

As The Miller correctly said earlier, the L2 and L6 are both original Convoy designs and can not legally be produced by anyone else. Hopefully we will never see clones of these lights but it’s quite hard to control in China. It wouldn’t be a very cost effective design to clone though. Simon isn’t making huge profits on these and it seems like a cheaply made clone would stick out like a sore thumb…

No J-Dub74 you say it wrong, IF we see a clone of the L series (so please make that L1 happen Wink ) we buy a L at Simon of BG/GB/DX/FT with the Convoy name.

Snip

Holding the BD06 and no sharp edges.
And while charging it shows red or green just like the 01
The only real difference is head size.
About more pronounced edges, I am thinking of a test to kind of prove “pocket friendliness” but havent figured it out yet
It is good to think of something so I am devoting time on it Wink

Sweet! The site didn’t go on about it as they did the 01 so I wasn’t sure. The bezel has much different crenelation on the 06 than the 01, 6 ridges instead of 5, and this on a smaller head so they are more compact, look to be more angular instead of flowing like on the 01.

I’ve had the 01 here, bumped output on it and fine tuned the beam profile a little, it’s really quite nice with a small bit of TLC to tweak it slightly. Smile

I can attest to that. Bought a bunch of cheap C8 clones at too-good-to-be-true prices, intending to just use them as hosts. Yeah, too good to be true.

I’d gotten some before, pretty decent brass pills, XM-L (genuine or lookalike, dunno, but pretty good), pretty bright (>300lm, at least, from ceiling-bounce tests), not bad for an Amazon special…

These… pfft! Plastic reflector, cheap featherweight Al pill, XP-E sized LB emitter, maybe 80-100lm of angry-blue light, tops. With a decent brass pill from FT that fit fine, a real 4300K XP-E2, new driver, it throws pretty nicely, but still isn’t a light I’d put much faith in. Still got the plastic reflector (ordered 3 different types of Al reflectors from FT to see which’d fit best), but just adding up the costs of getting the cheapo host to do anything (decent pill, reflector, switch, etc.), it’s just plain not worth it. I’d rather just get the real Convoy host from FT that’s all ready to go with solid parts, not crap. Much less agg as well.

If they were to ever clone the L2/L6, you can bet it’d be rated 45,000lm (maybe 150-200lm tops in reality), be half the weight, have horrible purple-blue 7500K LB XP-E clones, and just be an embarrassment to flashlights everywhere.

Sad part is, people’d buy ‘em.

So, got my new C8. Looks really nice. The glossy silver look is really catching.

However no matter what mode grouping I program the light to, no light is emitted in any configuration while in moonlight. Down to 1% everything is fine and on high it seems just as bright as my older C8s but no moonlight.

Not a huge deal, I can use it on a mode without moonlight, but just wanted to see if other people have/are experiencing the same issue.

Edit to help diagnose:

Tried with NCR18650B flat top, NCR18650GA raised flat top and EVVA protected NCR18650GA button top.

Programmed into configurations 2, 3, 8, 9 and same behavior. No light on moonlight.

Edit2 : Reprogrammed it back into a mode with moonlight and got the led to flicker on moonlight mode, eventually resting on a level that is indistinguishable from 1%. After a few cycles though, moonlight goes back to emitting no light at all. I actually have a second new C8 but left it on my desk at work without testing it. Eager to see if it has the same issue.

Hmm, curious observation msim. ToyKeeper has mad firmware skills, so I’ll bow out when she arrives. But until then…

I see Biscotti has moon defined as PWM level 1, but I’ve had trouble before with the LED not turning on until I started at 3 or sometimes 4. It seems like 1 just isn’t enough sometimes. I wonder if that’ll need bumped up.

TK doesn’t set a value of 1 out of 255 for moon with 8*7135 chips. Even one 7135 chip needs a value of about 3 or 4 maybe. So the dilemma most likely stems from the specific 7135’s on this driver not liking the absolute low value, it’s always a gamble, trying to get it as low as possible but still have it work on “all” the drivers. Really difficult to do.

Edit: I’m seeing values of 3,4,5,6,7,8,10,11… in the code for the 7135 driver. So 3 is the lowest and in some cases it’s not quite enough by a value of 1. If you set it that 1 or 2 higher, the vast majority complain it isn’t low enough. Set it low enough, a few get a driver that loses moon… whatareyagonnado?

Yeah Dale, dunno. I’ve been compiling a modified version of Biscotti today but haven’t had a chance to flash it to anything yet. The Biscotti source on launchpad has the following array of PWM values:

Quote:
#define RAMP_FET 1,10,42,75,122,133,255

Every other line of PWM values (commented out) starts out at 3, indicating she usually does use 3 for moon. I think I typically stick to 4 to be safe. Not sure why this one starts at 1.

Dale, what repository are you looking at? I only see one active line of PWM values (line 82 here), and it starts out at 1. Does TK have another place she keeps code?

I can live with it, but I would expect Simon/Convoy is going to hear from people who want a refund or new light because of the moonlight malfunction.

Sadly you might be right. that would be a shame too in my book…… considering the apparent reason it’s like that. Facepalm

Possibly, but hopefully this is just a one-off situation. And while I like having the option of a moonlight mode… how often do you pick up a light the size of a C8 and say “I want an almost indiscernible amount of light from you!”?

This world takes all kinds of people! Some of us code all day long, some drive tractors, other save lives. We’ve all got an amazing role to play! (not to down play TK’s great work – code can be a work of art sometimes!)

Very true! That’s why it’s really not a big deal. 100%-20%-1% gives me enough flexibility for a light this size.

Notice that the line starting with a value of one specifies it’s for an FET driver, not the 7135 regulation chip driver. Different beast.

TK sent me the code she was sending to Simon, I flashed it to a C8 for JDub as well as a different code set to a few other lights (mistakenly, sorry Jared!)

She very thoughtfully has the code set up for those who would like to tweak it to their own drivers, both FET and 7135 lines are present throughout, all one must do is choose which style they are using.

Please contact Simon through the store. I’ll mention it to him as well but I know he will want you to contact him directly. This is the first issue I’ve heard of but this is all completely new. Hopefully it’s just a fluke. Any problems will be resolved properly I’m sure. Simon would not ask you to “live with it”.
