First Flash light Recommendation? sofirn sp36 vs convoy 4x18a vs convoy m3c vs Haikelite MT40

hello there.

I am looking to get a good all rounder flashlight, and I have been searching for 3 days. I have gathered a lot of useful information from this site and YouTube. my requirements are both good flood and good throw. so I’ve learned that they are referred to as “search lights’. so after long search I am in a dilemma and I might end up geting 2 lights.. lets just say if I wanted to first get a EDC light which one should I get?

1. Sofirn SC31 pro $21 usd with battery aliexpress
2. Sofirn SP35 $33 usd with battery aliexpress

which one is better option from above. is there any other light one would recommend in the above category (small pocketable usb rechargeable waterproof good quality budget friendly) that is better than the two options I listed? is it worth to spend $33 dollars for sp35 or get sc31 pro $21?

And next question is about the second flash light category, I want to buy a manageable size mid ranger ‘search light’ type of light. i don’t like pencil beams or so called long throwers with very narrow beam!

Must have requirements:
1. budget under 100 dollars.
2. USB rechargeable (must)
3. do not get too hot (good thermal)
4. decent battery life
5. not too big in size

not too big, for example not Convoy L6 OR sofirn SP70 I consider them too big (although i love the light performance on those lights) but they are big and not usb rechargeable. I need something that can fit in for example a jacket/hoodie big pocket. so ive listed 5 below but i dont know which is better than the other or how they would rank..

1. sp36 (there is like 3 versions. all three versions selling for $50-52usd with batteries delivered from ali)

A. SP36 BLF – B. SP36 BLF Anduril – C. SP36 PRO

2. convoy m3-c (selling for $50 usd with battery delivered ali)

3. convoy 4×18a ( more expensive $76.35 usd with batteries and I don’t know if the quality/waterproofness is as good as sofirn)

4. Haikelite MT40 ( $64.95 usd no batteries seems like good specs but i dont know about quality from these guys, is it as good as sofirn and convoy?)

5. convoy 4×18a SBT90.2 ( $96.37 usd with batteries, I just learned about this one although I don’t know if its a thrower or a search light, I don’t know if the beam is like pencil which I don’t like.. would i have enough spread?

I want good light performance and I don’t want it to get too hot in high mode (not turbo mode) i only want to use them in high. which will give best high performance without getting too hot? which would you guys recommend for me as overall best choice based on my requirements? is there any other light that would do better than the ones I’ve listed? your help is greatly appreciated.

JMHO, but for the EDC, I’d suggest the SC31 Pro in 5000K. Slimmer, lighter, options for 18350 configuration, and Anduril firmware. I have two, love em. For mid-range thrower, maybe Sofirn or Convoy C8 with SST-40 emitter. Decent throw, wider beam, more spill.

…and PS: they both run 18650 cells.

sounds like you have one. is it true does it get really hot? how is the throw spread compared to the other 2 versions? the anduril version as far as specs seems to have the least throw like 350m than its the BLF at 550m than its the pro version at like 700m+

hi mate,

thanks for the recommendation, for edc have you tried the sp35 to compare it to sc31pro?

for the second recommendation ‘convoy c8’ its not usb rechargeable, that is a must for me. what about the other options I’ve listed?

I have the SC31 pro 5000k and I really like it. For EDC I’d pick this over the SP35 because it’s smaller and can fit in my back pocket without me really noticing it. I don’t have the SP35 but I do have the IF25A (4000k) that also uses a 21700 battery. This light I carry everywhere in my backpack but I find it a little bit too big for and EDC. I like the even beam (TIR optics) but for outdoor use I find it sometimes a bit too warm. It also can’t sustain the high output that long so for such a use case I’d prefer the SC31 Pro. Actually for real EDC-ing I use the C01S, doesn’t cost much but produces an amazing amount of light (on high, it has two modes and starts on low which is also really useful) for such a small AAA light. I carry it everywhere in my little right pocket. I also like the C01R a lot (red AAA variant with 3 modes) for night-time use, it’s beside my bed.

The SC31 Pro can also use a shorter battery tube so a 18350 battery can be used. I have some of those batteries on their way so I look forward to make the SC31 Pro a really compact light Big Smile I also really like Anduril, especially the battery-voltage check function. It can be a bit much with all the clicks (I sometimes get in the wrong menu’s) but that’s a small downside to the amazing number of functions it has.


I also have the SP36 Anduril in 2700k, 4000k and 5000k. I got the 5000k first and liked it a lot but figured I’d like the 4000k more because it’s slightly warmer and maybe a little bit more “neutral”. I found however that all of the CCT variants have a different purpose for me: 2700k is good for lantern/late night/indoor use, 4000k is good for overall indoor use and maybe a bit in nature (leaves and stuff) but for that I actually tend to prefer the 5000k because it produces more light, gets slightly less hot (I think) and it also throws a bit further. It’s good that I have all of the variants so I can compare them but if I only get to keep one I’s probably pick the 5000k (even though I use the 2700k more, it’s beside my bed).


The included batteries from Sofirn are not the best but perform very well, especially for the price. I’ve ordered a SP36 without batteries but I regret doing that because for the price you really can’t go wrong. The lights can perform slightly better with higher drain/higher capacity batteries but I only recently ordered some of those and don’t have them yet.

You can also take a look at Wurkkos, it’s a brand closely related to Sofirn (same factory) but they have different developers (I think). Maybe the TS30 can also fit your second category but it’s runtime will be lower than the Sofirn SP36 because it only carries on 21700 instead of 3× 18650, and the TS30 also doesn’t have Anduril.


Good luck Smile

The Anduril SP36 uses LED’s with a higher CRI value (Color rendering Index) so it’s supposed to have a better contrast between things at night, among other things. These LED’s tend to run hotter (not as efficient) as lower-CRI variants like the other SP36 variants use. These have a higher light-output and throw but I could not compare that. When I bought my SP36’s I chose CRI above output, but for your use case it might be the other way around.

On turbo these lights get very hot (make sure to temperature-calibrate the Anduril versions), a bit less on high.


EDIT: About the throw, the lights probably won’t really reach the advertised throw distance (not in regards to “useful throw” at least), so maybe divide the advertised throw in half or take 2/3rds of the original value. I am however very impressed with the SP36’s, certainly on turbo (but they step down after a while because they get very hot)

thanks for the explanation. so about the sp36 does it get too hot in ‘high’ mode if you run it for prolonged period? after how many minutes would you say it gets hot while running in high mode? (i don’t mean turbo im just talking about high)

also yeh i kinda got the idea the advertised throw is not very realistic after watching many youtube videos, you are absolutely right divide advertised range by half is more realistic..

the sp36 anduril version its running samsung LH351D and based on the spec sheet these have the lowest throw out of the three sp36 varients. also you did mention this version runs the hottest which is a huge down side for me. so out of which of the 3 would you say runs the coolest?

It doesn’t matter which you buy first. After a month on this forum you will own more flashlights than you could ever need . At which point you start giving some away so you can buy more expensive flashlights that do all sorts of things , which are of no value except to amaze and bewilder your friends and family .

Too hot is relative because on the Anduril version you can configure the temperature after which the light will automatically reduce the output. I think it can sustain the output on high though (at a high but not-too-high-to-hold temperature), but I’m not 100% sure about this. I’m sure there are tests about this somewhere but good luck finding them haha, the struggle is real.

Don’t quote me on this but I’m pretty sure the LH351D’s can be ranked from running hot to cooler as 2700k>4000k>5000k. I’m pretty sure the XPL2 or SST40 variants generally run cooler, or at least produce more light while producing the same amount of heat. The “quality” of the light the XPL2 or SST40 variants produce is however lower, but I’m quite alright with the SST40 5000k SC31 Pro (although it tends to have a green tint on low outputs when shining it on white surfaces)

I would go for the SP36, the normal edition. Usually I would prefer the more lumens of the Pro edition, but that uneven pattern that I saw in the reviews made me go for the plain edition. It’s just confusing when you have different intensities scattered all over the place, makes identifying things harder. But then again, that’s just me.
The size of the SP36 feels perfect in hand, and even fits in a jacket pocket.
For my first light, the SC31Pro might be too small, it feels more like a toy, especially compared to SP36. They are just two very different lights.
I still think it has it’s benefits and is a good light, but I’m afraid you might be disappointed with it as your only light.

M3-C is certainly very close to SP36, even though only on 1 battery (I use a 26650), it feels quite heavy. Nonetheless, solid performer. It would be even better if it would come in the SBT90.2 flavour.

Lets not talk about watches. I started with the $5.00 knock off Rolex watches from China Town in NYC back in the late 1970’s . Over the years I purchased an Omega a Rado ,a Panerai a Rolex a few Eterna Kon Tiki’s and a bunch of other watches I can’t even remember the names of . I am 70 now , have 3 grown sons and non of them wear a watch , except for maybe an apple watch .
Of course they were much cheaper when I got them compared to todays prices

In your 2nd category, I have both the SP36 LH351D and the Convoy M3-C XHP70, both in 5000k. You can run the SP36 at top of ramp with 18650 GA batteries without over heating. Turbo can only last a couple minutes or so. Being unregulated, the lumens are going to drop with battery voltage. The M3-C with run the highest level in winter temperatures and drop a little in summer until the battery reaches about 3.5 volts. After that it will only run at medium level. I would recommend either light. The 5000k LH351D is green at low levels and white at turbo. The XHP70 is white throughout. More run time with the SP36. The Anduril UI is better. Your call.

Yes, I have both SC31 Pro, and SP35 with ATR (6500K). I still prefer the SC31 Pro as an EDC for the reasons listed. My bad, I glossed over the USB rechargeable requirement. I do not own or have experience with the other lights you listed. Good luck.

This is a very interesting comparison, these two flashlights are neck and neck. I’m currently looking at some reviews and I’ve seen these very important and impressive results: the m3c holds the high beam (one before turbo) which is %40 it’s total output which is 1500lm for the entire battery life of 2 hrs and 20 mins till it turns off and it does so with ease it does not get too hot to hold, this is exactly what I’m expecting from a flashlight, now what are the numbers on the sp36 blf Anduril? For a high beam setting of say %40-%50 it’s total power can it hold similar numbers of 1500lms for the entire time till battery runs out without getting too uncomfortably hot and without dimming down as time passes?

It's nice to see you, easyshades!

The Sofirn SC31 Pro is an amazing flashlight, and very inexpensive considering what you get.

I prefer the similar Lumintop FW3A because it has a tail switch, but it's a lot more expensive.

Being unregulated, the output of the Sp36 will drop as battery voltage drops. Fully charged, I’d say it can sustain 1500 lumens without excess heat. If you don’t mind the 4 step ui of the M3-C it is great. I don’t use the ramping option because after Anduril, the M3-C’s ramping can’t compare. The 4 step ui is ok. Long press for lowest setting, Double press for highest and single press for memorized .

Gotta confess, that’s a hopeless question, as 99% of it would be personal taste. It’s like asking what’s the “best” flavor pudding, as there’s chocolate, vanilla, pistachio, tapioca, french vanilla, key lime, etc. (damn, now I’m hungry…), and one person’s must-have is someone else’s “ewww”.

Get one (eg, the SC31 is a good all-arounder), then see what different thing you want in the next.

My nighttable has like 6-8 lights on it, depending on what I want a light for. GTmicro for a small thrower, runtime not important. DC7 (Q8ish light) for a wall o’ light. EC50 for a nice wide hotspot and great beam. MH20 as my un-dethroned EDC light that does almost everything pretty well. E05 (Wuben) if I want a diffuser. Etc. And that’s not even listing others that go into rotation for one thing or another (WK30, SC31, E2L, etc.)

Same analogy I’ve been using forever, there’s no such thing as a do-all wrench, not even an adjustable. You might need a box-wrench, crescent wrench, socket, deep-socket, or even a special wrench for an O2 sensor or sparkplugs.

So forget about “Which light is The Best for me?”, and just start buying. LOL

thanks mate, the sc31 pro seems to be a favourite amongst the forum members here, what would be your choice from the second section “mid ranger flooder’?

i see, so as far as a ‘full charge’ you would say that it can also hold at least 1500lm till battery runs out without getting too hot to hold and is there anyway to program it to not drop below 1500lm?

haha buy em all is not an option atm lol, but whats your pick for a mid ranger flooder? usb rechargeable, good battery life, good size, good throw good spread just an overall daily use mid range thrower.

I don't know if this is what you're looking for, but my other favorite flashlight (the FW3A is my fave) is the BLF-D80v2.

It used to be dirt cheap, and now it's more expensive.

If you're looking for a pretty compact thrower with a tail switch, it's an excellent choice.

It fits in my pants/shorts pocket really well.

If it were still about $28, and if the brightest emitter were still available cheap, I would recommend it more.

haha buy em all is not an option atm lol, but whats your pick for a mid ranger flooder? usb rechargeable, good battery life, good size, good throw good spread just an overall daily use mid range thrower.

Wellp, “mid range flooder” and “mid range thrower” are mutually exclusive.

Will toss it out there, my MH20s are as yet un-dethroned by anything else as my EDC, even the ’31.

Simple dual-stage switch, incredibly intuitive UI, as compact a light as I’ve seen for an 18650, and a nicely balanced beam (ie, “compromise”) as is possible. If you still want throwier, get the MH20GT. If you can find ‘em, that is. Might have to hunt around a little.

Let’s put it this way, my MH20 and i332 have almost exactly the same shape and dimensions, both have on-board charging, yet the MH20 takes an 18650 whereas the i332 takes a 16340!

But as you’ll find out, Grasshopper, is that mid-anything will always be a compromise. It won’t reach far enough to be a good thrower, nor spread light enough to be a good flooder. It literally is mid-range. Fine for dog-walking or whatever, but forget about looking 100yd down a trail or lighting up a whole basement at once.

 

Yeah, some wanker will hoot’n‘howl that cranking up a light to 3000lm will light up whatever it is 100yd away, but it’ll be useless to see because the foreground 10’ in front of you will be lit up and washed out like with stadium lighting. That’s all that “useful spill” everyone talks about…

UPDATE: ill be buying the sp35 for EDC and for the midrange I’ve short listed these 3 ill buy one of them by the end of the week. any input on which of the three to choose would be appreciated. most important thing to me again is maintainable (at least %40-50) brightness throughout the battery cycle without drop in brightness or getting to hot to hold.

Sofirn SP36 BLF Anduril 54usd (rechargeable mid ranger, with batteries included)
convoy M3-C 54usd (rechargeable mid ranger, with batteries included)
convoy 4×18a 86.4usd (rechargeable mid ranger, with batteries included)

In your 2nd category, I have both the SP36 LH351D and the Convoy M3-C XHP70, both in 5000k. You can run the SP36 at top of ramp with 18650 GA batteries without over heating. Turbo can only last a couple minutes or so. Being unregulated, the lumens are going to drop with battery voltage. The M3-C with run the highest level in winter temperatures and drop a little in summer until the battery reaches about 3.5 volts. After that it will only run at medium level. I would recommend either light. The 5000k LH351D is green at low levels and white at turbo. The XHP70 is white throughout. More run time with the SP36. The Anduril UI is better. Your call.

This is a very interesting comparison, these two flashlights are neck and neck. I’m currently looking at some reviews and I’ve seen these very important and impressive results: the m3c holds the high beam (one before turbo) which is %40 it’s total output which is 1500lm for the entire battery life of 2 hrs and 20 mins till it turns off and it does so with ease it does not get too hot to hold, this is exactly what I’m expecting from a flashlight, now what are the numbers on the sp36 blf Anduril? For a high beam setting of say %40-%50 it’s total power can it hold similar numbers of 1500lms for the entire time till battery runs out without getting too uncomfortably hot and without dimming down as time passes?


Being unregulated, the output of the Sp36 will drop as battery voltage drops. Fully charged, I’d say it can sustain 1500 lumens without excess heat. If you don’t mind the 4 step ui of the M3-C it is great. I don’t use the ramping option because after Anduril, the M3-C’s ramping can’t compare. The 4 step ui is ok. Long press for lowest setting, Double press for highest and single press for memorized .

i see, so as far as a ‘full charge’ you would say that it can also hold at least 1500lm till battery runs out without getting too hot to hold and is there anyway to program it to not drop below 1500lm?


No. If that is your main concern, get the M3-C.

I see, so there is no way to lock in the lumens in the thermal settings of the sp36? I was thinking maybe that would be an option since everyone mentions the flexibility of the anduril UI I thought that would be a fix to the gradual drop in light as its being used, i just don’t like drop down in light while using a flashlight, id rather maintain the same light strength (example %40) till the battery runs out (I don’t mind if the heat/warmth of the light goes up) but if it does not do that or has great thermal handling than that is also a huge advantage.

EDIT: I just searched up the manual that comes with the sp36 there is this part in there.

[“2. Temperature limit. This
sets the maximum
temperature the light can
reach before it will start
doing thermal regulation
to keep itself from
overheating. Click once
per degree C above 30. For example, to set the limit to
50 C, click 20 times. The default is 45 C (15 clicks).
Hint: If you don’t click, the lamp will leave the value
unchanged. The lowest value the user can set is 31 C,
by clicking once.”]

Could this be it? i mean its set at 45c i could raise it to 50c (122F advertised touch limit) but than how long would it hold the light on high beam before thermal throttling kicks in. would it hold it till the battery runs out like a good flashlight should?

in my growing collection, my SC31 Pro is my love-hate torch. Buy it. You won’t regret it :). Except, maybe... when you compare it to the more expensive torches you buy...

I love its great brightness, good heat management, superb small size, and long runtime. I hate that it outdoes my other lights when I take all the factors together.

(I also have Wurkkos DL30, DL40, and TS30 and like them all. The DL40 is awesomely bright and long-lasting, with good heat management - but it’s 2 x w21700 :). The DL30 is definitely more of an underwater torch -it rapidly heats up, because it’s a much smaller torch, so less mass to dissipate heat. 

The WK30 is fun, the UV is neat and the deep red, the reason I bought it, is brilliant. It’s white is totally outdone by my SC31 though.

The HD20 I mention last: bought after reading a very a favourable review but it’s the only light I regret buying. The brightness and throw and runtime just disappointed relative to my expectations. If anyone is in the UK and wants to buy it nearly new... Wink It would make me happy to pass it on to someone who’d appreciate it more,)

thanks for the explanation. so about the sp36 does it get too hot in ‘high’ mode if you run it for prolonged period? after how many minutes would you say it gets hot while running in high mode? (i don’t mean turbo im just talking about high)

also yeh i kinda got the idea the advertised throw is not very realistic after watching many youtube videos, you are absolutely right divide advertised range by half is more realistic..

the sp36 anduril version its running samsung LH351D and based on the spec sheet these have the lowest throw out of the three sp36 varients. also you did mention this version runs the hottest which is a huge down side for me. so out of which of the 3 would you say runs the coolest?


Look your original post was massive & my patience prevented me from reading it all. A year ago I had a plastic dolphin torch with a flat big 6v battery. I needed a good light for a number of reasons likely similar to yours. Ok I got out of control & probably own too many but now over 50 lights. They all do something better/worse and are different. Point being you ideally need more than one light to have the right light for the situation. Good news is your at the right place & great performing top quality lights can be bought very cheap. Don’t sweat every detail, generally the more lumens a light produces the more heat it generates & if it’s small that amplifies things. But you don’t need to run then full noise all the time, often @50% output it’s more light than anything from decades padt. All the lights your looking at are decent quality affordable options. For about $100 you can buy a 2/3 lights that will last many years. I say just buy a few and get ya feet wet.
