New Convoy C8 – Clearly better

Pat, there is no “varnish” and there is no “coating”, it’s the same anodization as the black flashlight except for the black dye added in the process. Essentially, there is no black water trapped in the microstructure of the ano.

Same light, same quality, same surface hardness and durability, with the exception that small nicks, scratches and dents won’t show up as well on the silver finish as the black one. :wink:

Doesn’t hurt to ask and Simon is very accommodating. He will take care of all your requests if they are feasible.

He has said yes to both installing AR glass, and the new driver/firmware. :partying_face:
Just awaiting paypal invoice info now.

hi,

Another question on Convoy C8, is this unit passed the IPX-8 standard for waterproofing? TIA! :slight_smile:

Awesome. :+1:

Very awesome!
Still awaiting response over PayPal details, but I’m Simon is very busy, so I’ll wait a few more days before reminding him.

Yes. All versions of the Convoy C8 are rated IPX-8.

All sorted. Cost $1 extra for new firmware in each Black S2+. Big thumbs up to Simon for going out of his way to keep us Flashaholics happy.
:beer: :slight_smile::slight_smile: :partying_face:

I like that.

It looks like it’s silver-anodized (silver dye used instead of black). So, it should be a lot harder than bare aluminum but visually similar. A bit more shiny, and a lot harder to scratch. And if you wear through the anodizing it should be difficult to spot.

On another note, my empty Convoy C8 seems to weigh a bit less than an empty Kronos X6. It’s slightly bigger but slightly lighter. I haven’t tested throw yet but the C8 reflector is significantly larger so it likely throws a bit better. It’ll be fun fine-tuning the focus before I measure it… I kinda took it apart right away to get the driver out.

Life has been a little turbulent lately, but I got some pictures… A capacitor and diode are a little too close to the MCU so they prevent contact with four of the pins (of which two are needed). Someone probably just didn’t realize that SOIC8 keep-outs were needed around the MCU. It’s pretty unusual for customers to want to reflash ROM like we do.





About 15 seconds with a file and your SOIC clip will fit right on there. :wink:

The cap can be moved over to the next set of pads, and the diode can be swung around a bit, maneuvered to give clearance. Looks like it really is true what they say about the devil being in the details. :wink:

TK, I’ve heard the blue clips are nicer, but do you happen to have one of the cheapo black clips to test? Mine doesn’t seem to have any plastic extending out beyond the width of the MCU.

Also, do the two components (resistors?) in the center of the board interfere as well?

Let me address these things…

The color:
To the best of my knowledge there is no dye used at all. I believe the metallic look is caused by the light being bead blasted prior to clear anodizing. For example, If you bead blast aluminum and then clear coat it, the result is a silver look. I am awaiting official confirmation of the details of the procedure and am also seeing if we can get a just machined look in the future which should involve nothing more than skipping the bead blasting process prior to anodizing.

Throw:
My C8 lights do out-throw my Kronos X6 though I don’t have any equipment to test the numbers. The Convoy C8 with the XPL-HI throws pretty well stock but can definitely be improved if you can get the emitter a bit further into the reflector. The simplest method I’ve heard of to achieve this (modders correct me if I’m wrong) is to sand down the centering ring to make it thinner. This allows the reflector to sit a bit lower, then replace the stock o-ring at the lens with a little thicker one to make up for the difference which will probably be 0.5mm or so. I may get brave and test this over the weekend. That would be my first real mod. LOL

Chip clip:
Thank you for the pictures! That is exactly what I needed to see. I’ve already sent them to Simon along with an explanation of what would need to change to make this home-user-flashable. I don’t know how difficult it will be for them to rearrange things on that board and I can’t make promises but I will try to make this happen. If it’s not doable does anyone know of a smaller clip or clipping method?

Edit: Once again proof that I type too slowly. I see there were two possible clip solutions posted while I was typing! :person_facepalming:

got mine. My first light (it is convoy!!!) have few problems here and there including few scratch, just consider it “additional features”. Keep up the good work.

Yes J-Dub74 a C8 out throws amd stays cooler then the Kronos x6
I have a Convoy C8 with the exact same driver, led and tail pcb of the X6 so have compared them side by side.

Just ordered mine on Ali. Waiting on the order processing now. I’ll report any QC issues here when it arrives.

But it’s ugly.
It’s not the “C8 look”.

+1 !

It seems (to me) to be the obvious thing to do, in stead of pulsing 3 Amperes.
.
edit:
It’s been discussed further, should have read on…

So i read the whole topic, only skipped some of the chip programming stuff.
For all i care LOW - MED - HIGH is enough, maybe a ‘moon’ mode too.
Finally on this page i read this, which i think is a kind of an issue:

So this is not solved in this newest version, unfortunately.

It seems the C8 is made for XM-L(2) with dome.
The base of the XM-L is thicker than of the XP LEDs, and the XP-L HI has no dome to optically raise the die.

I recently got a black C8 with XP-L HI and not only was the spacing between reflector and MCPCB too big, on the top the centring spacer shrouded the LED.
So i filed down both sides, and now it’s okay.
Looking in the head (at a certain angle) i can now see the edges of the die reflected in the reflector.
So it would be good to use a flatter centring spacer ring, with 0.7mm maximum spacing between reflector and MCPCB and lower rim around the emitter.
But, indeed, you will need a thicker O-ring in the bezel too
Or two normal ones on both sides of the lens maybe (haven’t tried that).
But the reflector now rests on the head, it can not go in deeper, even if you remove the centring spacer.

Another solution would be a thicker MCPCB, say, 2+ mm thick in stead of the regular 1.6 mm
Maybe you can discuss this with Simon, it would improve the C8 for XP (3535) LEDs.

For the rest:
I’m not too sure about the clear anno looks…
I would personally prefer it as seen here: New Convoy C8 – Clearly better - #51 by vwpieces from member vwpieces

But this seems to be polished bare aluminium, which scratches easily (or is it anodized?).
I could de-anodize my UltraFire C8 with the ‘American oven cleaner’, but haven’t found it here in NL yet…

For the other rest:
I saw a picture of a Convoy C8 with a 18350 battery tube and i love the idea.
Anyone know of a short tube that fits the C8?

For the remaining rest:
Great stuff, i’m a Convoy fan, especially the C8. (actually, i only have 2 C8s by Convoy)
Will get a grey one too at some point and hoping for that SS bezel to become available.
Simon is cool and so are all of you who participate in creating these lights.

I was getting kind of annoyed that Simon wasn’t replying to my message, but it appears he had actually replied within 4 hours and I didn’t receive an alert notification from aliexpress. :person_facepalming:

He offered to send me a new piece of glass.

I’ve noticed that you don’t always get notifications from existing message threads on Aliexpress.
