Convoy C8+ - single mode option?

I’m looking for a low cost, high quality light for non-flashlight friends and family.

Past experience has shown that multi-mode lights are a failure with this demographic; they end up using the light exclusively on whatever mode first turns on (either low or Turbo.)

As such, I’m looking for a single mode light that offers 5+ hours of runtime of ~200-300lm, or 10hrs ~100lm. Enough light to get the job done, but enough runtime that even with the battery 50% discharged, they will have several hours of runtime. Malkoff M61L/M61LL would be my go to, but since these will be gift lights, I’d like a cheaper option.

Looking at the C8+, it has options for 10%, 20%, 35% light levels – but only as part of a multi mode.

Is there someway to get a C8+ programed exclusively to a single mode? And using the XPL C8+, what do the 10/20/35% modes correlate to in lumens and runtime?

you could get one of the standard factory type convoy c8s

sst40 with 3 modes

just set them all to 50%

ive got the sst40 from banggood and ive configured it to 10% 30% and then 100%

it is super easy to configure

you could just configure it so first mode is 50% and second mode is 50% and third mode is 50%

its the firmware without heating ramp down, so at 100% ran for over 30mins it would be really hot, maybe untouchable

50% and your safe

i bought the rampping model

super easy to program

can program any of the 3 modes to anything you like

just program them to 50%

That light says its 2000lm, so 50% would be 1000lm x ~1hr runtime? That’s really unsuitable for a utility / dog walking / blackout flashlight for normal people.

Ideally I’m going for ~100-150llm xs 10hrs or 200-300lm’s x 5hrs.

Do any of the Ramping ones have a 10-20% setting?

there is about 35 ramp settings in steps

so i could imagine it would start from 5% or something very low and go to 100% in steps. im not sure how it works out the steps but ive just tested it

mode 1 and 2 can be configured in what every steps you want

say both at 20% or 15% etc

and the 3rd mode is a bit funny , it can be a flasher, a strobe or beacon. or 1% or 100% or a slow flash at 20% brightness

ive not tested it at low on how long it lasts
but ive configured mine as this

1st mode is about the 5th ramp
2nd mode is about the 10th ramp
3rd mode is 100%

100% gets hot

i could think that if you put for example put the first and second mode to say the 5th step like me and the last mode as 1% . it could work

ill test how many mAs the 5th step draws in a miniute

3000mA battery would last you theoreticly 10 hours on the 5th ramp setting

id be happy with 9 hours

You can get a C8+

with a biscotti driver and only ONE 7135 on board giving you a 350mA high (10 hours on a 3500mAh 18650)

and set the driver for one mode 100% only. (option 12)

You can probably order this driver configuration from Simon at Convoy.

Thank you, that sounds promising.

What would 350mah translate to roughly in lumens? And would the output be regulated (ie a constant ‘X’Lumens for most of the battery life?

And how would I phrase the order request? “Can I order 3x Convoy C8+ with a 7135×1 driver for 350mah, set to 100% only?”

350mA could be 150 lumens but that is a very rough estimate.

Output would indeed be regulated for most of the battery life.

Your order request would be for Convoy C8+ with biscotti driver with ONLY ONE 7135 (350mA).
Also led and led tint of your choice. (xpl-hi is a good option)

Setting to one mode is something you will do yourself.

Thank you! 150lm x 10hrs would be ideal performance for a general purpose, newbie proof flashlight.

Would this Clear C8+ work?

I would prefer a clear one, they are both pretty and easier to locate.

Sure, it will work perfectly, just make sure to mention it while ordering.

Thanks again. I just messaged Simon, I will report back.

I hope it works out; frankly I could see this being a popular mod for those looking for a simple 18650 light to give to friends and family.

So the project is a go, I ordered the C8+ XPL Clear, and Simon agreed to do the 1×7135, single mode @ 350mah.

Will report back once I know more.

If the light ends up a success, I plan on ordering 4-5x more, and pairing them with the Keepower USB rechargeable 18650, then handing them out as gift lights.

Sounds like you got a handle on things pretty good. I have some S2+‘s with 1 chip and a few with 2 chips. They are the wife and kid’s single mode lights. The XP-L Hi in those C8’s are pretty throwy. Are you positive they wouldn’t like something a bit more floody? I think the C8’s are awesome. The fairly throwy beam with the large smooth reflector and XP-L Hi doesn’t exactly make it the best all around light. I have a few C8’s with XP-L Hi’s and they don’t get used much around the house, the fairly narrow and intense beam make me grab the S2+‘s for that kind of stuff.

If throw is whats needed, those C8’s will definitely do the trick on a budget.

Seems a waste to do something like this to a throwy C8, but diffusion film works wonders.

Just used my (Xeno) E03 with DF on the front lens. Great for a nice even blanket of light, perfect for indoors and close-up. Whether lighting up a crossword puzzle to try to read smudged-newsprint clues, or lighting up the steps going down to the basement, a super-floody beam from DF is perfect, moreso than even a normally floody light.

And unless you put it on the inside surface of the front-glass, it peels off easily if you want to remove it (temporarily or otherwise).

I had and am still considering the S2+ as well.

My reasoning for the C8+ is that ‘throwier’ lights are more ‘lumen effecient.’ For example, the 150lm setting on my Armytek Predator Pro can still punch out a long ways; at 100yds its much brighter then my 780lm Quark.

So for a single mode, ~150lm light, I figured the C8 would end up punching above its lumens, especially if used outdoors (walking the dog, looking for the lost cat, dazzling tresspassers, etc.)

That said, I have been quote satisfied with the range of my Malkoff M61LL, which is a 100lm OTF light, and uses a reflector thats much smaller then the C8 / Closer to the S2+. However, all the pics of the s2+ seem to show a really floody beam, whereas the Malkoff has a decent spill + strong hotspot.

Another option is M4U with 1*7135 – same Biscotti firmware, bigger battery and very important for newbies – USB charging.

some great options people have been saying

my pennys-cents worth

you cant go wrong with convoys
ive got 3 convoy c8s and a few more on te way
ive got 2 s2 on the way and a fw1a on the way

it adictive torch owning! but its fun

sand coloured c8+ that i took the gubbings out of the black c8+
running sst40 6500k 2000lm (factory specs) and standard firmware that is factory, programming is super easy and actually very good. this is my EDC ,tail cap says 4.8amps

clear c8 with xhp50.2 6500k with bistroHD firmware configured with 4 mode, .low-med-bit more then med-max (temp controlled) not sure the lumens but matt smith says the are about 3000 . tail cap test on high makes 9.65amps on my multimeter but i dont trust that so much

the convoys s2s that come are 1x sst40 5000k and one host that is a project , not sure the led or driver going in

the fw1a maybe my EDC when it comes and i ordered the xhp50.2 .not sure the tint but it has OP reflector

one thing missing from convoy c8s is usb charging. it would be super cool if someone made a tail tap that had some usb charging in , im sure there could be a engineer that could make one

imight even try salvage a zoomie i have and try make something

1*7135 C8+ reminds me of the old 6-cell alkaline maglites. Not a ton of overall brightness but a lot of throw that made them surprisingly useful.

Absolutely; 5D maglite was 151lm – but only for 30 minutes, after which brightness decreased by 50%.

Beyond that, the 150lm setting on my Armytek Predator (C8 sized) is surprisingly effective. And the 150lm setting on my Armytek Barracuda (64mm head) is awesome with how far it throws, can easily light up a palm tree at beyond 100yds.

For a regular person / muggle, I think a 150lm C8 would seem incredibly bright and effective; when I checked my Aunt’s 3D maglite in her drawer she keeps for emergencies, the batteries had degraded to the point that it was putting out ~1lm….

For 3D and 2D Mags, I kinda like the LED replacements. They ain’t screamers, but they’ve got more consistent output vs hotwire bulbs, and even alkaleaks last longer.

Still gotta pretty much beat people over the head with said Mag to get it to sink in that alkaleaks don’t last forever, and “emergency” or not, dead cells in a light won’t be of any use.

I hadn’t really considered them in awhile, but their newest Rechargeable light actually looks pretty solid:

Maglite Rechargeable

A USB charging version based on 2×21700’/ 2×26650 would be really promising as a ‘civilian’ light. Even moreso if they designed it to also function as a power bank.

I feel like a 150 lumen C8+ is just not going to be enough light

I’d recommend a driver with 4* 7135 chips which you could remove one at a time to get what you want. It’s going to be disappointing to receive a light that’s too dim and you have to buy another driver.

this is what i was thinking, a c8+ running 150 lumens is such underkill

ive want 2 modes , 150 and 500 at the least

c8 is such a nice torch to be running 150 lumens

but if its what he wants then its ok

I spent $100 on a Malkoff MD2 M61LL, specifically to have a single mode, 100lm light that could run 10hrs.

So by comparison, 150lm is 50% brighter, and at $25, the C8 350mah is 400% cheaper.

I’ve been around flashlights a pretty long time; I had a 65lm incan Stinger, back when that was considered ‘blindingly bright,’ and later Innova X5’s ~2003, back when that was the height of LED tech. That was pumping out ~31m (on High!)

As such, I remember that 150lm is actually really bright. And paired with a decent reflector, 150lm has plenty of effective range; my Armytek Predator on 150lm mode (44mm head) has no problem at 100yd.

That’s why real garbage C8 clones on Amazon would still appeal to some as “blindingly bright”.

Stick a cheap Angry Blue™ XP-E clone (not even a real one) behind a plastic reflector and belt out a whopping 70-80lm into a teenytiny hotspot, and it’ll be pitifully dim but still manage some decent throw. And they’ll get those 5-star “Wow! That’s BRIGHT!!” reviews on Amazon.

Can someone confirm that 350mA on the XPL HI is 150 lumens out the front not just led lumens.

You could also ask Simon to do 1*7135 S2+ with XPL HI and a smooth reflector for better distance. I used to have one and thought it was excellent.

I’m also curious what the 350mah translates to in actual lumens.

You had a 1×7135 S2?
