[Review] Convoy S11 GT-FC40 26650 Flashlight (with runtimes and pwm tests, etc)

Convoy S11 GT-FC40 Flashlight Review

Official Specs and Features

Here’s a link to the official Convoy S11 GT-FC40 flashlight page.  This is not a referral link.

Versions

This is a Convoy flashlight, so I’ll go out on a limb and suggest that there are 100 versions of the S11 specifically.  Of “this” version (which I’m saying very non-specifically) there are basically three.  The body colors are Black, Gray (seen here), and Silver.  This S11 has the GT-FC40 emitter, but there are two versions available:  4000K-4500K (seen here), and 5000K-5500K.

Price

This Convoy S11 GT-FC40 flashlight weighs in at a reasonable $27.53.  To the best of my knowledge, this is the least expensive complete flashlight with the GT-FC40 (which is precisely why I bought it).


Short Review

As I hinted above, I mostly bought this light to test this neat GT-FC40 emitter.  There are other less expensive ways to get this emitter, but not without modding.  There’s an mcpcb and driver for the Convoy L6, but…  what better reason to buy a new flashlight than this?  So this review is sort of two parts.  First the emitter:  yes, it’s great, buy it.  Second the Convoy S11.  It’s fine.  The fit and finish only get an “ok” from me, and 26650 tube lights are not tiny, but at this price, I consider this to be a good value.

There's more at my site, including runtimes and all that other good stuff. Head over there if you're willing, and if the table above doesn't satisfy your need for data.

I don’t get it, The chart shows it ran at full power for 10 minutes then dropped to half power and ran for another 80 minutes? No?

It would be interesting to see graphs of 35% and 50% without cooling. And find out how many lumens are in 50% mode.

Thanks for the review Smile Thumbs Up

Sorry for my poor english.

Has anyone else gotten this light with this LED?  I’d be interested to hear more about it.

I have it. Great light, Very floody. Almost no hot spot. Looks like an S2+ on steroids.

Great review, always comprehensive! I would love the see this emitter in a light with the heat handling/sustained output of the M21C but with a shallower reflector for a wider floodier beam.

Sounds like a good bike light.
