As in the title, but sell me on your best alternative. This is what i’m leaning towards but I know you guys are a wealth of experience.

I don’t have a real need for it. Likeliest use case is getting stupid at a camp site. Here’s what appeals to me:

-Stupid bright

-Decent sustained bright

-Mostly floody

-3 x 21700 — long run time

Nice but I could live without:

-on board charging

-power bank functionality

Skeptical of:

-cooling fans because i don’t want to hear my light.

Wish it had:

-Anduril 2

I’d go $200 without blinking. If it’s more than that I’d better believe I’m getting something pretty special.

Thanks!

Hello,

I recently bought an L21B from convoy, which appears to be a fantastic thrower from my 4 camping trips of use. I was hoping someone could explain the differences between the 3x21 series. They come in A, B, C, D, and E versions. Or if there is a resource that explain the difference that I’m missing please let me know. Sorry to waste your time if there’s an explanation page I’m missing I swear I tried to find the difference for a half hour today. https://convoylight.com/collections/3x21

^{*Convoy does not publish lumen specs for each CCT offering. I suspect the 12,000 lumen claim is for the 6500k option. It would make sense that 3000k, 4000k, and 5000k would have a lower output than the 6500k option.}

Pros:

• Output doesn’t drop much for the first three minutes on Turbo

• Sturdy build quality

• A good balance between flood and throw

• USB-C Charging

• Flat-top battery adapter included

Cons:

• Real-world lumen output is lower than claimed*

• UI is inconsistent & below average for the industry

Summary: ★★★* (3.5 out of 5)

I purchased this unit because of the premise of a budget realm soda can form factor light that utilizes the new XHP70.3 HI emitters. I'm a big fan of soda can-style lights; most of my collection consists of these. I used three pieces of fully charged Lishen 35amp LR2170LA cells for my measurements. The CRI measured at a 70.5CRI on the higher lumen settings. The CCT jumped around depending on where the sensor was within the beam, but the average CCT I read was 4050k. Convoy claims 12,000 lumens*, but I could only attain 7,500 lumens at turn-on, even with fully charged cells.

For the first three minutes, output remained steady on Turbo. After three minutes, the output significantly dropped and then stabilized around 1800 lumens around four minutes. At the five-minute mark, I concluded the test.

The build quality is above average. The USB-C port and onboard charging work well. I found the beam profile to be a mixture of flood and throw - it reminds me of a jack of all trades but a master of none. The UI is counter-intuitive and inconsistent. On my example, the ramping speed is extremely slow. You can click six times from off and attain a more reasonable ramp speed, but once you activate Turbo, you lose that setting - odd. Overall, this is a decent jack-of-all-trades light - it doesn’t do anything poorly (except the UI). Still, it doesn’t do anything particularly great, either. If the UI were better, I would have no reservations about giving this four stars.

^{Disclaimer: This light was not provided to me by any entity and was purchased utilizing my own resources. I have not been paid or otherwise compensated in any form to review this item, nor have I been withholding any problems or defects.}

I recently received a convoy 3x21b, which I was super excited about. I have a lot of hot rod flashlights, head lamps, edc’s, etc. but I don’t have many big lights (though I do have a d18 and a sp36… but I digress). I’d seen a lot of reviews praising this light for its good sustained output, long battery life, and good tint. I had seen some people complain about the UI, but I’ve had lights with suboptimal UI before and I could get past it.

Yes, it’s great at sustained output and it produces a very useful beam with good tint. I like that it uses 21700 cells instead of 18650. Now the UI, in terms of how the interface works, is fine. But holy hell who approved of this ramp speed?! It’s so slow I actually thought my light was broken, because for the first 1-2 seconds of ramp I barely see a change. I decided to time it and compare to an anduril 2 light - my d4k will ramp from turbo all the way down in about 2.25 seconds. This light? I timed it at NINE AND A HALF SECONDS. So you’re outside and decide you want to turn your light way down as you approach someone walking towards you, and doing so takes almost a full ten count. I don’t know how they even approved of this in the first place. I might keep the light, I might return it, but I figured I’d share, because if someone told me it would take 10 seconds to ramp I never would have ordered it.

While I know I should not get into can lights because everybody I know that has one never uses them after the initial novelty wears off, I'm liking what I've seen in reviews and runtime graphs, looks like these will sustain around 3,000 lumens on high for most of the battery.

Would love to hear thoughts on this light from owners as well as other high output sustaining lights similar to it as other options

After a chipped LED and a shorted driver, third time's the charm! I finally managed to my Convoy 3x21B modded from the stock XHP70.3 HI to sliced 90 CRI XHP70.3 HDs. Overall I'm very happy with the mod; a 25% reduction in output in return for +20 CRI and negative dUV on all modes. I think I'll be keeping this one for a while as an efficient 90 CRI flooder/thrower type of light. AFAIK it's one of the most affordable efficient big flooders you can buy.

Convoy 3X21B 21700 flashlight

XHP70.3 HI R70

XHP70.3 HI R9050

Assuming 5000k what is the difference?

This will be a gift to replace a friend's old q8. Is this a decent flood withsome throw?

Tia

First beam is the 3x21b, second is D4K with 519a and boost driver. Both on turbo.

Sofirn Q8 Plus: 6 XHP50.2 HD (they say "XHP50B"...) Convoy 3X21B: 3 XHP70.3 HI

Price Range: Don't wanna spend 200 €. More like 100. Sofirn has a very compelling deal at below 70 € right now, that's only valid thru July 31st. I'm okay with buying used and don't need batteries included.

Purpose: This is gonna be a multi-purpose light that will be set on the ground or a table ceiling bouncing, mounted on a tripod or superclamp (UNC-threaded hole is important) or hand-held for a walk if need be. But I've got more compact lights for night walks or hiking, so size and weight are not no. 1 priority.
What I really want is two things:
Sustained output and
Lumen-hours
For both of these efficient drivers and great emitter efficiacy are key. XHP50 and XHP70 LEDs are great for that. I want 5000 K (4500 - 5700). I dont need high CRI, 80 would be nice, though. The Sofirn seems to have a crappy driver. Or the temp threshold is just set very conservatively... I couldn't find much info about the driver, so it would be great if you could shed some light on that. It does run Anduril 2, so that's a huge bonus.
I haven't found info about flashing Anduril to the 3X21B driver, but at least I know that it's a boost driver outputting 15 Amps at 6 Volt. And reviewers have drawn some nice runtime graphs for it.
Also: is there maybe a way to put a better driver into the Q8 Plus? In case it's really not that good. But it has its three cells in parallel and needs to drive XHP50s, so it has to step up the voltage. (Or am I wrong here?) This may not be a guarantee for 90%+ driver efficiency, but most of the time this is the case...

Battery Type & Quantity: I'm looking for a 3x21700 "soda can" light. 4x18650 is pretty much the same size, but has less energy, so the light would have to make up for that somehow... Let's keep it 3x21700.

Size: The Q8 Plus has a very nice form factor. The Convoy is longer and wider at the head but also good. I don't want a huge head like 100 mm or more in diameter.

Type: Soda can. :-)

Main Use: Laying/tail standing somewhere putting out lots of light for a few hours. Setting up for an event, tearing said setup down, small construction work.

Switch Type: They're all side switches, anyway.

I keep looking for online reviews, but so far my Google fu fails me.

Would be good to hear direct from any owners, how does it perform?
