@zak, Fireflies has been using the FA3 chromacity tint bin.
Most of what is listed in the spec sheet are unfortunately unavailable for purchase in small quantities. There are very few Cree 5A 5D tint hi CRI emitters that can be bought by small consumers. I did buy a XHP70.2 5D 80CRI from Kaidomain and it has a nice rosy tint but such emitters are rare to come by.
Why do you want to remove the knurling Simon? It’s beautiful as it it’s and the appearance of the S2+ has always been your trademark.
Using chrome material to process knurling, the defect rate is very high. If I don’t process knurling, I may reduce the cost by 1/3.
:+1: copper pill!
Please dont remove knurling. Its good for grip and adds surface area for heat dissipation.
removing knurling doesnt mean smooth surface , i will consider “grip” ,too
Will it be offered in the clear ano version?
Yes, I can supply clear version
Thanks for offering the new emitter options. The S2+ was always a good budget light, but XM-L2s aren’t exactly pretty. I maintain a popular recommendation list and I was happy to be able to add the S2+/SST-20.
FA1/4 bins for the SST-20 would be most welcome. I’ve been using FB4 from Kaidomain, and the tint is OK, but could be improved. I can add to what others have said about the 219C as well: it’s fine at 2.8A. It’s fine much higher than that, actually and can take more current without failing than the SST-20 can. (7A is fatal to an SST-20.)
I’d really like to see an official listing for the C8+ with the SST-20 and 7135x8 driver. I know it’s possible to custom order it that way, but I want to add it to my list, and it’s much easier to provide a direct link than explain a custom ordering process.
Thanks ,buddy, i will add 7135*8 option for C8+ and S2+ nicha 219C flashlights soon
If you have problems making enough profit it would be a better idea to slightly rise the price of your products or stop implementing rising cost improvements such as new copper pills etc. in favour of maintaining the current build quality and knurling.
See your lights are popular because they offer very high quality for a decent price, not because they offer low quality for a low price.
I personally would like to see project of S2+ with no knurling. There are various manufacturers that don’t use it (Zebralight, Armytek) and people are not complaining about low build quality or lack of grip on their products.
I’d much rather have copper pill than knurling if I could choose.
Will a cool white luminus LED be available for this someday? Or would that be an SST-40?
OK, this is going to be a post which will probably heat up some discussion…
Copper is overrated, brass or aluminium wil do just fine
Especially for a S2+, it doesn’t matter much, since the flashlight is just to small to dissipate the heat very well, so it will gain maybe a couple of seconds in heat transfer.
The power of Convoy is that the quality of your products is always good and the design doesn’t change suddenly, (like what happens with other Chinese sellers, to reduce cost and get a higher profit rate) so all available spare parts always fit. (as is not always the fact with other Chinese sellers)
So, to reduce the price, please only remove knurling and keep using the existing pill, which is good enough.
Please get rid of the 3/5 mode driver and ONLY use biscotti
A smooth S2+, i can live with that.
Zebralight does use knurling on the SC600 handheld models, which are still way smaller then the S2+. Armytek doesn’t even know how to proper assemble their lights so adding knurling is probably too difficult. And objectively a plain tube without knurling will be more slippery in wet conditions then a knurled one, or when used with gloves.

Have you done any testing to compare it? Do you have data to back this up? I timed my copper host S2+ compared to aluminum regular and high mode can be maintained at least twice as long without burning. Output also drops slower when measuring lumens with copper pills compared with brass pills when using triples.

yes ,i have SST40 LED in stock now ,but driver is not ready,yet
I think I misrepresented what I meant.
First of all, I will not reduce the quality of the product. The current knurling is difficult to process, and one third of the products will be scrapped directly.
I don’t meant to make a smooth surface.
I just want to change a style, on the one hand, it will improve the product yield, on the other hand, keep the original feel of grip.
For example, I can change it to the following
Thanks Simon, I’ll check back when driver is ready. Also the new rendition looks very nice!
Is the S2+ Nichia 219C in 5700K 95% CRI too? Or just the 4000K version?
No, the S2+ 219C is only in 90CRI.
Just the SST-20 is available in 95CRI.

Nice! I like it.
No, the S2+ 219C is only in 90CRI.
Whoops. But that’s also for the 5700K option? And is 90CRI still considered HighCRI? I want to get a glimpse into the HighCRI goodness so many people seem to enjoy - would this be a good specimen?

219C 90CRI ,friend
