Believe it or not…That convoy s2+ beam is nearlt as nice as my Fenix BC30 beam/tint _.
It is my commuting light for short night trips. The 500 lumens mode is awesome. It would have no problem holding the 1000 lumens (cooling) while riding.
I guess they work for some people and not for others. Are you riding roads or trails? I ride mainly roads and have not problems with the 2nd and 3rd mounts on the pictures. Otoh I’m still looking for a mount for a 26650 sized light.
The second mount wouldn’t fit my S2. The third one required a ton of effort to get the light in and out each time. I think i was literally scraping away a little of the mount plastic each time i put the light in. It’s super hard/dense rubber. Feels like the vulcanized rubber from a hockey puck. I’m using the first mount now just for the convenience of removing the light. It’s just not very secure.
Was the 2nd mount too big? Most of my lights have a 25.4mm body.
Yeah, it was too big. It was made to fit a cheapie 3*AA zoomie light that came with my old bike. I tried some foam and rubber pads but at the end, it just looked ridiculous.
You might check with M4D M4X on getting a discounted price (link) for the Fenix ALB-10 Bike Mount.
I did. 
What do you guys think is the max amps one can push an S2+ to not overheat as a bike light?
I used my S2 with 2100mA driver at full until the battery die many times.
It was during winter so it surely helped to keep it cool, and had no problem with bumpy trail.
Thanks X3. I like to push my lights to the limit, so I’d like to know what might the limit be for an S2+ on a bike. I’d like to do more than that? Maybe 3amps?
I use those ones for my S2 -> https://www.fasttech.com/products/0/10003391/1251801-universal-adjustable-mount-holder-clamp-for-bike-l
I have the 2800mA S2+ and it gets hot on high very fast. If you’re biking in cooler weather, it should be ok. I never run mine on high while biking long distances though because of run time and I live in a very warm climate most of the year. There are some interesting mods that people have used to add extra heat sinking for bike likes though. I’ve seen a heat sink from a CPU modded to go around a flashlight.
Thanks. Think I’m going to do some testing… 
What we need would be a C8 for heatsinking with a big TIR for floodness
Mmm, what about a Convoy M1? Very good heat sinking. Too little flood?
I don’t know M1, I think they are more throwy than S serie and less than C8. This might be a good compromise !
M1 with an OP reflector is rather nice. It doesn’t light up as wide an area as an S2+ at similar output levels, in my experience. It tends to be a fair compromise, as was mentioned, between the throw of a C8, and the flood of an S2. I like to use mine as a good all-around, multi-purpose light. It’s tough, not too big, good heatsinking. But I EDC an S2 at 2.1A max, the form factor is just better for me for every-day tasks.
If I have to loan out a general purpose light, its one of my M1’s. With a 3B tint, it’s perfect. I have one in a 4C tint that very much feels like an old style incan light, but with much higher output of course.
I sometimes (ok, often) feel bad that I can’t use all of my lights all of the time.
I also use this one and i like it, straps are strong and rubber is adaptable to the diameter of the light/handlebar.
I started out with one of those on my handlebars. It is just OK and I got tired of having to readjust the holder on the bars. If you have a 1” diameter light, the universal U shaped piece of rubber (without the 360º functionality) is the best. I’ve been using mine for four years and have hundreds of hours holding C8s of various generations without any problems.
Yes, C8 may be too heavy for fasttech´s holder, weight make it spins arround the bar.
Did you try using the holder upside down? Using the small cavity on the bar helps holder to stay in place.
Hi a1penguin. What exactly are you talking about here? Can you maybe supply a link? Thanks!
