Convoy C8+ 18650 Powered Thrower with Biscotti Flashlight Review

There’s a new seller in town!  The US-based store MohrLumens.com has opened and is selling the likes of Convoy, Lumintop, and Sofirn lights.  The benefit of course, is that the items are shipping from the US, so you’re likely to get your items much quicker than from other (even official) channels.  MohrLumens.com sent the Convoy C8+ for a bit of testing, and I’m hopeful that many more Convoy reviews are on tap!  This Convoy C8+ is a 18650 thrower with Biscotti.  Read on for more!

Note that this light was damaged in shipping.  Big ol chunk in the side of the package straight through the box and straight into the box.  Like some USPS employee smashed the package under a piece of equipment or whatever.  MohrLumens.com will treat you right if this happens to you (which is pretty unlikely).


Official Specs and Features

Here’s a link to the official product page.

Versions

There are a ton of versions of the C8+.  There’s a black body (seen here) and a tan body.  There are many emitter options, too.  The Luminus SST-20 5000K is the version I have in for testing.  Also options are Cree XP-L HI, Luminus SST-40, Osram KW CSLNM1.TG, Nichia 219c, and Osram KP CSLNM1.F1.  There are plenty of choices!

Price

The version as tested is going for $19.95 at MohrLumens.com.  You can get yours here.


Short Review

This is a great little thrower, and probably the very least money you can spent to get 500+ meters of throw!  When speaking with MohrLumens about emitter options, I mentioned Cree XP-L HI being my favorite but I have to say I really love this SST-20.  It’s neutral without being yellow, but still not muddy.  A bit hard to describe.  The light handles well and the build quality is great, and again, this light is under twenty dollars!

All my Convoy reviews!
  • Measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

What’s Included

  • Convoy C8+
  • Lanyard (attached)

Also see in the photo above the damage USPS did to the light.  It’s pretty dramatic really.

Package and Manual

There is no manual included.

Build Quality and Disassembly

Convoy seems to make lights that have a higher build quality than would be expected based on the price.  Again, this light is under $20.  The build quality is much higher than $20 would predict.

The C8+ differs from C8 in a few ways, including the tailcap seen below.  There’s a bit more grip, and it feels beefier than my other C8.  Unfortunately no comparison photos – the C8 makes a fantastic giveaway light – it’s inexpensive and trustworthy.  So I don’t still have any of my many others!

The head is covered with fins which help with cooling.  Not that cooling is all that important here, because the light isn’t driven terribly hard.

The cell tube has a good bit of knurling, which aids grip.

Here’s that damage again.  The perpetrator actually sheared off metal and left a bit hanging.  I can knock that off and then fill those spots with some Sharpie and probably never notice it again.

There’s very minimal branding on the C8+ – all seen below.

The tailcap is held together by a retaining ring, and there’s a beefy spring in there.

The head end also has a spring.  This means any type 18650 will work fine.

Despite being different on each end here, the cell tube is reversible.  Typically the unanodized end will go on the head side of the light.

The head components are held in place by a retaining ring, too.  All the parts are extremely accessible!

The bezel unscrews easily, leaving access to the mcpcb, which is held in place with two screws.  The little plastic on the metal reflector is the centering ring which goes around the emitter.

The tailcap threads are anodized, square cut, and very smooth.

Due to the purple hue seen below, I expect the lens has AR coating.

Size and Comps

Body Diameter: 25.5mm
Head Diameter: 44.5mm
Length: 141mm

If a light will headstand, I’ll show it here (usually the third photo).  If a light will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 format.

Here’s my closest similar sized light, the Lumintop GT Mini.  I thought about cleaning this one off but then I thought “why not leave it?” because…. wow I have so many lights, and some of them really don’t get used much….  case in point….

Retention and Carry

For the C8+ there is only a lanyard to aid in carry.  The lanyard ships attached.

This lanyard attaches on the tailcap, through these two holes on either side.

The lanyard always ships from Convoy in the [incorrect] configuration seen below…. This irks me slightly, because it prevents clean tailstanding.

You’ll find the orientation below better suited for all things!

That’s it.  No pocket clip, no pouch, nothing else.

Power and Runtime

The C8+ is powered by a single lithium ion cell – this light fits an 18650.

Due to long (enough) springs on head and tail, the C8+ will work with most (or all) 18650 cells.  Unprotected flat tops, long protected button tops.  They should all work fine.

Below are runtimes on the highest two modes.  The output isn’t regulated, and drifts downward as the cell voltage drops.  There’s a stepdown after “a while” and the output drifts again.  The output shuts off at 3.0V

High has no stepdowns all the way to the shutoff.

Testing with a bench power supply, the light shuts off hard at 3.0V.

Modes and Currents

There aren’t really any claims for output on this little guy, but here’s what I found.

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
100% 732 2.74
35% 318 1.20
10% 95 0.34
1% 10 0.06
0.1% ~

PWM

The light has PWM on all four lower modes.  Surprisingly I wouldn’t really call even the lowest mode “visible” PWM, despite how it looks in the graphs.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  And here’s the worst PWM light I have ever owned.  Also one of the very first lights I ordered directly from China!

User Interface and Operation

There’s just one switch on the C8, a tail mechanical reverse clicky.

This driver is known as “Biscotti” and has a bunch of mode groups.  Mode memory can be turned on or off (yay!), and programming is easy!  But there are simply too many possibilities for me to list the UI in a table as I usually do. Here is Simon’s flow chart for the UI.

From the mode group selection above, the light ships in mode group 1.

LED and Beam

The emitter in this Convoy C8+ from MohrLumens.com is a Luminus SST-20.  The temperature is 5000K, and let me tell you, it’s very appealing.  The reflector is smooth, and provides a beam with a tight hotspot, but reasonable spill.

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

Test light is on the left!

I compare everything to the KillzoneFlashlights.com 219b BLF-348, because it’s inexpensive and has the best tint!

Conclusion

What I like

  • Low cost thrower!
  • Nice tint/tep on the Luminus SST-20 5000K
  • Good UI and plenty of UI options
  • Easy to avoid blink options
  • Direct access to low (if memory is off)
  • Memory can be turned on or off.

What I don’t like

…. I really don’t not like anything about this light.  For twenty dollars, everyone should have one.  I don’t like that USPS marred up the surface.  But that is what it is.
