Triple XP-L Convoy S2 MTN Edition BLF17DD Review

This is a quick review of the Convoy S2, sold by RMM at Mtnelectronics.com (in pieces.)

First I wanna say big thanks to Richard at mtnelectronics.com .. without him it wouldn’t be possible, and he put up with a bunch of shit out of me in getting this light lit. (The spacer does not fit the S3, DMM’s do not read 10+ tailcap amps, etc etc. Sorry Richard, I’ll know better next time.) Also a big thanks to this forum in it’s entirety, as without ya’ll well.. I’d still be carrying a Klarus XT-11 2012 model and thinking it was bright and moderately priced.

So my thoughts:
ZOMG WHAT A LIGHT. That’s really all I need to say, actually. It’s a massive wall of light. Certainly 3000+ lumens. Just as bright as a fandyfire/SRK, and actually brighter inside of 140 feet, due to the TIR!! Excellent color with the dedome and the 10507 Carclo TIR.

HEAT: fortunately either rmm forgot to program the sixty second turbo timer, or I messed it up during the build, but at the 30 second turbo step down on a fresh battery, the head of the light is bordering on too hot to touch.. ! Out at the business end, anything less than an inch away is in danger of combustion; a dollar bill laid flat across the TIR will ignite in seconds.

more data on heat:
With an initial head temp of 80 degrees F, after a 30 second turbo run, the head temp rose to 125 F, and took 20 minutes to cool back to 85 F. (Can you say copper?? amperage!?)

  • Total current loss after 3.5 minutes of 30 second turbo sprints: 870ma
  • approximately 125 miliamps per 30 second run.
  • 2000 miliamp Samsung INR 20R could last for 16 thirty second sprints, or 8 minutes.
  • 30 second turbo timer is a safe bet, 45 seconds would likely be the longest you would want to run this light on high.. 60 would be really pushing it.

Distance: ~ 140 feet
A gold unmodded Fandyfire 3x SRK XM-L U2 running on Samsung INR 20R’s
A 18sixfifty mod 4x SRK XM-L2 half dedomed running on standard panny’s
A beat up Convoy S4 XM-L2 U2 pulling about 4 amps on a VTC3
A stock stock Convoy XM-L U2 on a laptop pull
And then the Convoy S2 triple XP-L on a Samsung 20R pulling over 10 amps

That is technically correct. He only sells the parts, you have to actually assemble them.

He decided it makes too much heat too quickly to sell out right.

wdkingery — I guess you’re running a fet setup to achieve 10+ —— I’m running close to the same setup in Solar Force P1D host (1 of their thickest wall host) with a modified Sportac module— It will run at max around 3-4 minutes—I had Richard make the medium around 4.5 amps still plenty of light —I’ve ran it upwards of 10 minutes—amperage most likely had drpped a bit—you’re right at 10 + amps I call mine the SICKNESS

yes this is the actual light that we have modified, for sale at fasttech. here’s a photo of it I stole from Bort:

here is Bort’s review of the stock/unmodified light.

this is what 3 XP-L’s under a TIR looks like:

Wow first post!
Yes, I don’t quite know the whole background to the thing, but here at BLF we have our own custom FET-based driver, known as the BLF17DD. RMM at mtn sells them pre-built, and it’s what I’m using in this flashlight. DD stands for direct drive.

The new XP-L in a 3up setup is seriously a new level of flashlight.

It’s like that time you got your first LED flashlight and were amazed by the output. (Mine was an overpriced Innova X5 with Snap-On written on it. I was so enthralled I bought another for my cousin cause someone just had to see this thing.)

The pictures I take come nowhere close to what I see— I quote Vinh about a light he had modded “makes me giggle everytime I turn it on”

OMG, you're killing me! LOL!!!

i am waiting for my XP-L emitters to arrive from FT for the same exact build. Now I know what to expect. Big Smile Awesome job, bud!

i also have an EE X6 in the works with quad XP-L emitters. Emitters and driver should arrive next week. I expect 4000 lumens at least.

On another note, wait until you see what DBCstm just finished. Silly

All of you are killing me!!! 

I guess I need to speak to Richard about the triple I want to build. Not quite as beastly but .... Oh crap..maybe just build two.

It's the simple things that we take for granted that cost us the most

I have the parts ordered for the same build as well. Looks amazing!

Man that’s insane. What’s the longest you can run it for before heat becomes an issue?

On triple at 5+A on a DD…not long..under 60 seconds (I am going to finally build me a BLF15.17DD and see if I can keep it around 4-5A w/o overdriving it too hard and set the turbo timeout for 30 seconds)

Beautiful thing is STAR firmware and it’s ability to auto throttle back to a lower current…got a 1/2 to full minute of sock em in the puss mega light if you need it, but the protection of the PWM going to approx 50% output automatically to protect itself.

I was even thinking of potting the inside of the pill to add a bit of thermal mass but it’s not really going to improve it that much

I have a regular S2 w/ aluminum extension epoxied in [better thermal transfer]), right now I have a regular Nanjg 105C w/ 4 extra chips on it flashed with a non standard STAR (instead of a click down from 255 to 120~ it steps down incrementally, 1 tick every .25 sec, but I think the FW programming borked and will no longer start in anything but moon mode and the modes won’t change, going to build the BLF15.17DD and put regular STAR on it)

Dedomed XPL is about the same beam pattern as non-dedomed XPG2s.

I have a couple of triples in S series host— from my fooling around (testing) 2.5 amps seems to be the limit for extended run times-actually for this type of floody light that’s still lots of light—I’m building a couple XPL s with a 4.4 30sec turbo and a high of 2.5—Also has anyone else tried the 10511 optic the little bit of throw you loose it more than makes up for with smooth beautiful light—no kaleidoscope edges

I’ve been swapping email toward a triple Rebel using this star and one of these optics. Heck, I’ll get several different optics and swap’em.

Comfy—never thought of polishing—I’m gonna try modding a 507 though from the underside—maybe light bead blast or blacken in—I like the hot spot but hate those outer effects from the internal reflections

I’ve yet to run it full steam for very long.

It does get warm quick, but I think it’s not as bad as originally reported, as it’s sitting on hundreds of grams of pure copper.

These lights are the best EDC I can imagine. I’ve been building them for a few months now playing around with different hosts to see which I like the best. I haven’t stuck a BLF17DD driver in one yet though. Might need to give that a shot. I’ve been running mine at 3-4A with a 60 or 120 sec turbo timer. They do get fairly hot even at 3A in 120 sec – though not nearly too hot to hold. But yeah. They are seriously awesome.

I propose naming this the Mtn Electronics triple STD.  It'll literally create a burning sensation in your pants.

A word of warning to those that have or are building Triple XPLs with the DD17 in any small host and especially the Cypreus... Laying down reading this evening somehow I turned the light on in my pocket, burning a hole in the pocket of my slacks and burned my thigh. Not bad, so far just one blister. Could have been worse! Just thought a word of warning might be good for the others that have or are contemplating a stupid bright light. Mmmmm, does anyone smell bacon?

The low mode should be lower.

I have the Cypreus EDC 18350 as well, with Richards copper heat sink/spacer in an all copper light using triple XP-L’s with the BLF17DD driver. 2960 lumens OTF from a single Efest Purple cell. Start amperage ~9.37A. Insane stuff.

Yesterday I crammed an MT-G2 into an Eagle Eye X6. How about 7.17A at the tail cap for 3485 OTF lumens from a single emitter? :bigsmile:

2 of the Efest Purple 18350’s have to be massaged into this small light. Spent most of the afternoon on it.

Both of the above pics were taken with the Canon G1X at ISO1600, f/5.6, 1/2 second exposure in Manual with manual focus and 2 second timer. Same settings, same spot, different days.

Gonna have to take another beamshot of the Cypreus Triple XP-L, that looks way to different, maybe I didn’t have it in Turbo or something. (been feeling bad for a while now) A lot of my lights have 5 levels, I put 7 in the Cypreus to maximize it’s usefulness. Perhaps I went to 5 and took the shot, with a migraine like headache from a previous concussion that’s probably what I did.

Glad it turned out well!  The original one I built was in an S3 and it got too hot for me to comfortably touch in about 30 seconds, pulling over 12A from a 20R.  The S2/S6 with the massive copper spacer obviously buys you a bit more time before it heat soaks, but it is still going to be getting hot in a hurry.  

Be careful!  It may be improbable, but I would hate to see what would happen if a lead desoldered itself and a 20R created a dead short inside the light...when I've shorted them usually a trace or something else has popped like a fuse, but if it didn't it could be crazy.

Also, these little triples have so much light coming out the front that up close they burn things like a magnifying glass focusing the sun!  The light coming out the front will burn stuff, like paper, clothes, and skin.  

I will probably offer these at around 6A, but I won't be building them with an FET driver.  What you build for yourself is your business, but I think these are just a little too much for most people to use safely.

How hard was it to get the xp-ls to fit in the optic?

Dedomed no work is necessary.  Domed doesn't fit without modifying the optics, which are difficult to open up without destroying the clarity or uniformity of the lens opening.

I wonder if it might be prudent in lights such as this to Arctic Alumina Thermal Adhesive the wires into place after all is established and working well? Just in case one does desolder from heat, it won’t shift and cause that short problem. Cheap enough insurance anyway.

It’s funny how you say be careful watch out for desolder problems—I added a brass spacer to my tail spring in my P60 version of this light—seems like it desoldered and moved—I don’t remember it being that crooked on the spring—might have been a cold joint- I know one thing the battery is quite hot as well

The problem with AA is that at temperatures hot enough to desolder a lead the bond actually gets quite weak, although it may provide some insulation to the top of the wire to keep it from contacting.
