Thank you! I plan on using the BLF A6 firmware so it seems this switch will work very well.
Mountain Electronics sells the
Convoy S2+. So does the manufacturer of Convoy flashlights, Shenzhen Convoy Electronics Co., Ltd. No problem with fakes from these vendors! Simon, the owner of Shenzhen Convoy Electronics, is currently offering members of BLF a
15% discount on the blue S2+. If you send him an email, he might extend that offer to the red S2+ as well.
Mountain Electronics can also make a modded version of the S2+ that uses the same emitter, driver and firmware as the
BLF A6 Special Edition.
The BLF driver and firmware are great because they give you seven constant brightness modes, including a sub-lumen low and a direct-drive turbo that produces anywhere from 1100 to 1400 lumens, depending on battery. I like this better than the three constant modes the stock S2+ has.
If I were buying a stock S2+, I would go for 7135*3 or 7135*4. That way high, medium, and low modes all become more usable (at least for the way I would use the S2+). The 100% high would not overheat as quickly. Both medium and low would be lower than they are in the 7135*8 version, in the ranges I prefer.
The S2+ has a short body tube that is sold separately. By swapping the regular tube with the short one, you create a "mini" S2+ that runs on 1x18350.
Blue and gray versions of the S2+ are currently available. Green is on the way. As I recall, the gray version does not use the steel switch. It has a "regular" switch that is covered by a rubber boot. Because of this, I think the gray S2+ it is a bit more waterproof than the colored versions.
Are there any other differences between the gray (natural) version and the colored ones? I am not sure. I have read that the dye process used in colored anodizations limits you to type II. Natural anodization, of course, can be type III. It is possible that the gray S2+ uses type III anodization, while the colored versions use type II, but I do not know the fact.
I bought a couple of BLF A6 flashlights to have around the house as backups. They won't replace the two flashlights that are my go-to general purpose lights. Those are the
Zebralight SC62w and the
Nitecore P36, both of which I feel are more dependable than the A6. At the price, however, the A6 is an amazing backup.
If I did not already own the A6s, I would probably buy a couple of S2+ lights for the same purpose.
By the way, the
Convoy L2 is back in production, with a design that is close to the original available now. This light has an XM-L2 emitter in large, SMO reflector that is mounted in a 65.4mm head. It runs on 1x26650 (or 1x18650) and has a current-controlled driver that has no PWM.
The L2 is getting good reports, but I have never tried one.
