The XinTD is built like a tank. Other than that, they’re quite similar. Now that Convoy C8’s have an integrated emitter shelf there really isn’t a whole lot of advantage to the XinTD except for more thermal mass. Both are quality lights, to be sure.

I guess I got rid of my XinTD C8, can’t find it. But I did find my SupFire F9, similar size, nice style, don’t know if they’re making it anymore. The anodization is a sort of brown color and shiny, nowhere near what Convoy is doing. And it has the old style aluminum pill. LOL

Leave it to Convoy to show a guy how old lights once loved have become outdated….

I have a XinTD C8 and I can confirm the quality is excellent. Looking at it next to the latest generation Convoy C8 the biggest difference I see is the XinTD is roughly half an inch longer. Most of that difference is in the tail cap. I’ve read that the XinTD head and reflector are different internally and have heard arguments that the XinTD is “internally superior” to some degree. That may be true but I don’t really know. I have both but at least in the beam I do not see a XinTD advantage, in fact the hot spot on my Convoy is a bit tighter with the same emitter. To be fair both lights are modded and not by me so I can’t really confirm specifics. My XinTD C8 and my Convoy C8 are both excellent and by far the best C8 specimens I have seen.

Any word on when the new firmware/UI will be standard across the board for the other Convoy models? Thanks.

The New drivers will have a contact regulated output based on the number of 7135’s you select.

They are also a fast PWM so you will not see any flicker or hear any whine, as I assume that os what you are talking about.

The beam that comes out of a Convoy C8 looks cleaner, less rings…from what I’ve noticed anyway. The reflector of the XinTD screws into the pill like a P60 drop-in reflector does. It seems like the XinTD has a better beam pattern with domed emitters than it does with HIs or dedomed emitters.

In the process of ordering some drivers.
A 4*7138 that I plan on configure for the modegroup with a low highest for my wife’s short S2+
And one with more chips sure I will find a light for it.

Yes, he is one of the few stores that I don’t worry about products being genuine from. He even lists some of the off-brand flashlights he sells as having Latticebright led’s!

I searched for “biking” in this thread, but did not find any detailed info. Is there a video of the biking mode? I’m curious what the frequency of the strobe is. I find as a driver (and a bike rider) that high frequency strobes are terrible on my eyes. I’m happy with the XinTD for night riding, but daytime strobe would be beneficial.

Biking strobe is about a 50% level I think, with a one second stutter of High or Turbo that gives like 5 or 6 pulses in that second. It’s main objective is to make a car driver realize that the light he’s seeing needs some attention, it’s not static.

Does this driver use the stutter or the flash? Same basic idea either way, except the flash only flashes once instead of “stuttering”. I prefer the flash myself, the stutter is quite annoying as a driver IMHO.

First you think it is a cop, then you get distracted and keep watching the light. A proven fact is that you are FAR more likely to hit something if you are looking at it while driving. When racing on a track you learn to always look where you want to go and never at anyplace you don’t. So I could actually see the flash being better for the biker as well.

The flash is enough to let you know something is there but not enough to distract IMHO.

It’s the bicycle strobe that TK has put on the A6 and Bistro before this. Same thing.

Not sure what you mean by flash vs stutter. In about 1 second it flashes 5 or 6 times, I call that a stutter, result is the same to me. When in the configuration mode the “stutter” is dimmer, whereas in the Bicycle Strobe it’s brighter.

FWIW, I too have been trained to hit what I’m looking at and have wondered if an inebriated driver would be prone to hit the flickering light or steer clear.

Simon is truly a certified flashaholic!

Out of the box you already have a light that comes with AR coated lens, DTP board and a driver with awesome UI, it is indeed a strong rival to the XinTD C8 especially at a lower price.

Now imagine that Simon would use a FET driver in this light… Silly

If I don’t already have two C8 which were modded by myself few years ago I would’ve bought this shiny Convoy C8 in a heartbeat!

In the bistro firmware options TK has 2 different bike modes setup. One is what you are referring to with the “stutter”. The other is a simple single flash at the same time interval. I prefer the single flash myself. I was not sure which one she put into this firmware.

Of the hundred plus drivers I’ve built with Bistro, I’ve yet to see that. Interesting.

The option is under the “full_biking_strobe” option. If you comment that out it will go to the basic single flash instead.

Same deal as the police strobe, if you comment out the “Police_strobe” define, it will revert to the simple constant strobe instead of the alternating one.

Once again I prefer the simple version as strobe is basically worthless in a tactical situation over turbo. Strobe IS fun to play with due to the way people seem to go into stop motion on the other hand and the constant strobe does this better. I actually added a few different constant strobes to my version of bistro since I had some extra space left. Great way to have fun at night with kids!

I just tested two variations of Bistro, the one that shipped in the X6/X5 lights and the revision that was SUPPOSED to have shipped. Both have the same bicycle strobe whether reversing into it from moon or setting it up as option level 8 on the newer firmware. Either way, they both work the same. About 2 seconds on a medium output level (about 400-500 lumens) then one second of stutter which is about 6 flashes of Turbo.

What am I missing?

TAce is saying in the code for Bistro (before flashing to the MCU) you can set if biking strobe “stutters” or just does a single bright flash every few seconds. He is asking which option is built into biscotti or whatever we’re calling it.

The stutter is the default. That is what comes in the X6/X5 and that is what is in Bistro-mini for Convoy as far as I remember… I sent the primary C8 test light to JDub, he can verify it…. I just remembered I also have it on my ReyLight Brass AA… hang on…

Bistro-mini has bicycle strobe in three places, level 1, 4 and 7. All three have the stutter in the bicycle strobe.

I don’t ever open Bistro in my AVR programmer because it wont re-write it – I always get a ton of cautions and errors with any change. And since I seldom use Bistro due to the bounce-to-moon issue I haven’t seen that option.

And FWIW, I did open the Bistro-mini in AVR and it’s MUCH different, there’s a veritable Library of stuff in there! A simple change I tried to make gave me all the errors in the build so again, I haven’t modified it.

Edit: I’m assuming what you’re asking is found in this section of the code…

#define TURBO RAMP_SIZE // Convenience code for turbo mode
#define BATTCHECK 254 // Convenience code for battery check mode
#define GROUP_SELECT_MODE 253
//#define TEMP_CAL_MODE 252
// Uncomment to enable tactical strobe mode
#define STROBE 251 // Convenience code for strobe mode
// Uncomment to unable a 2-level stutter beacon instead of a tactical strobe
#define BIKING_STROBE 250 // Convenience code for biking strobe mode
// comment out to use minimal version instead (smaller)
#define FULL_BIKING_STROBE
//#define RAMP 249 // ramp test mode for tweaking ramp shape
//#define POLICE_STROBE 248
//#define RANDOM_STROBE 247

Yeah, the only way to access the single flash version is by editing the code for bistro. By default it is the stutter option. It does take up a lot more space then the single flash though so I was not sure if TK may have gone to the single flash for the tiny13.

Far as the errors go, we were talking about this in the firmware thread a week or 2 ago. TomE posted some things to get bistrol to compile on Atmel studio, I gave up awhile back and just use linix for it now. I might try atmel again at some point.

Correct, if you comment out “#define FULL_BIKING_STROBE” by changing it to “//#define FULL_BIKING_STROBE” then it will only give a single flash instead of the stutter.

Looking at that sinpit of code, it looks like TK simply edited out all the options for bistro to get the size down to Tiny13 sizes. I should look at the full code, with an OTC added to a 105C I wonder if it would work like bistro on the 13A with most of the features removed. I have some 105c’s to use up but had not decided on a firmware.

After my initial problems, it’s compiling fine for me too. You just have to get all the directories right for the header files. Definitely different than everything on the 13 was.

Anyways, wrong thread

I like how TK set’s it up, can’t wrap my damaged cells around the code to make changes anyway, so… shrug. Some famous person once said “It is what it is.” (Yes, I know, it was Justin… aka Old-Lumens)
