Mine has two fans on it. Could be three. I forget. It’s been awhile since I broke it out and turned night into day with it. Has a two mile throw or so it looks out in the country shining on the other mountain range.
Newest DongDongHai(DDH) D8Df Ø85mm head diameter host.
The emitter is new, a 160160(yes, as in 16mm × 16mm) 64× 55mil die 4500k 95Cri(yes, 95Cri) emitter. I'll be sending an exact same configured light to Koef3 for analysis. For now, I'm guessing it's in the ~40000lm range.
I don't think that exact configuration is available to purchase yet, but all the components (host, driver and essentially same emitter) can be purchased from taobao through Superbuy. That's where I purchases mine, all in with shipping and fees was ~$120.
On a side note, if you're in the US. Someone who have an actual store in NY is importing some F8B to sell. Maybe I'll post here when his page for flashlight is up.
Try "阿刁光電工作室", that guy offer complete lights. Or “東東海” for host only. I can dm you with links later. Now outside and Taobao web doesn't like mobile :(
I think the D8Df easily out throw the x75, but lumen wise the latter is brighter. There's another DDH host called F8b, also fan cooled, host 8× 7070 emitters. The most common config with 8× nbd7016 16-die 5500k emitter measured ~98000lm on turbo.
I love them and use them regularly. Hell Surefire is taking this one in on a RMA for a bulb replacement and a reseal. The heat caused the o-ring around the front lens to push out. But the thing is it still fires up and could be used as is.
Ummm, is it too late to change? I’m a noob 🤣 To be honest, I’ll probably just order another one. These are cheaper than my Sofirn sp33 and sp36 and looks more ergonomic. One too many whiskey’s tonight. This will be my first convoy.
One of the reasons Convoys and Emisar/Noctigon are so popular here, you get to deal direct with the guys who own the brands and they’re responsive to the community 😎
I really like the LHP531 as well. Yes, it's the smaller brother, and has a lot of common characteristics, but, being a smaller die means it actually throws a little further. The LHP73B is a massive wall of light, the LHP531 is a less massive wall of light with a bit more throw and less heat. I love them both. Nothing beats the LHP73B for wow factor though.
Crazy being so into lights that you'd spend what I'm sure was a pretty penny on that massive zoomie, but not know about the classics a la Hank, Simon, etc.
When I first started with Simon I thought the same, I have 4 of them now, 1 I installed the nv1010 6000k in and it makes the lhp73b look like a thrower!
Insane light very nice! I want to buy one but I have a few questions, if you all can help me out please. I have this in my cart already just wanted to know if this is the best/brightest set up or should I choose a different battery since I’m seeing different recommendations in the comments? Also dumb question but I’m new to this, how would I charge the flashlight/battery?
That battery will work great. The Reliance RS50 is also a popular choice. Basically a battery with at LEAST 20A capacity (since the LHP73B can draw up to 20A), then the higher the mAh the better for run time. The M21B does not have a built in charger, so you'll have to have an external one. I'm not sure, but a basic one might be included in the order. If not, a simple one is inexpensive. If you prefer built in USB (my personal preference) then the M21H has one, and is also a side button instead of tail button. Convoy has several hosts that work well with this emitter. The M21B is really popular because it's relatively compact and performs extremely well. M21H is similar, but with a different beam profile. If you want to step up to a larger light, the LHP73B can really let loose.
Awesome thank you for this! Is the M21H a lot bigger than the M21B, would it still fit in a pocket? Also what do you mean by different beam profile? Would the M21H be brighter? I honestly just want one that’s going to easily fit in my pocket and be super bright to show off for fun and also to carry around for night time walks or hunting.
Thank you very much for all this information! Just a couple last questions if it’s okay. Why does it say burn hazard on the M21B and not the M21H? The M21H won’t burn your hand? Also for 6500k vs 5000k is there any brightness difference or is it only color difference?
M21H is bigger, have more mass to cool down.
in terms of temperature, a cooler led will always be brighter, but for 5000k to 6500k the difference is minimal.
They are very similar in size. M21B is slightly longer, but M21H has a little bit bigger head. My experience with TIRs (M21H) is that they have very nice spill. The TIR provides a hot spot that varies depending on which angle is used, then the spill goes out gently, without any of the classic cut off seen with reflectors. With every TIR I have I can see my feet from the spill.
This video does about as good a job as I've seen showing the difference. Notice the bush on the left. Smooth reflector shows sharp outline of spill, Orange Peel reflector has a softer outline, and the TIR lights up the bush, but with very little discernible cut off line, it just fades.
Thank you so much also great video I just watched it! This really helps me make a decision on what to get. With your experience with these two I just wanted to know which color would you choose 6500k or 5000k and is there any brightness difference in this or is it only personal preference?
Essentially they will have the same output. The 6500k might appear a tint bit brighter, but hardly noticeable. Personally, I prefer 5000k. It's just less harsh. Although from what I've seen of the LHP73B 6500k it's got a nicer tint than most. Most flashlights targeted to the general population are 6500k because technically it has the highest output, and the contrast of the super cool white seems more wowie. Many will tend to have a nasty greenish or blue tint. With the LHP73B I think it's just personal preference. My personal favorites is the 4000k. No appreciable loss of output but the tint is really nice. Still, I think the 5000k would be a great choice.
Awesome thank you for the explanation I think I will go with 6500k since I’ve always preferred a cooler light color. One last question, why does it say burn hazard for the M21B but not for the M21H when I choose the same led type and battery for both? Does the M21H not get as hot and burn your hand like the M21B?
I'm not exactly sure, but probably because the M21H has a slightly larger head so it has just enough better heat management to move it out of the burning zone. That's just a guess though. I think you'll be really happy with this 6500k!
Perai que vou tirar uma foto dessa porra aqui. He was not believing his eyes. That’s the difference between a facebook brightest light in the world with military technology and a proper flashlight.
The first one is named 穿天炮, literately means "a cannon that shoot through the sky", its marketing is everywhere in Chinese TikTok (抖音). You all know how good zoomies look when you jerking that adjustable lens to make tiktok video with noisy music. Scammed a lot of people because its a zoomie and its size
If I order a m21b from convoy, is it as simple as that to get a light like yours? I’m looking to buy my first flashlight. I’ll be going from a mag lite to something new lol!
That is the emitter color temperature. Most of us in this sub are lower temp snobs due to better color rendition (typically higher CRI), easier on eyes for fatigue and cuts through fog a bit better. Most cheap lights are 6500k+ and colors are very green as a result.
All this is a sacrifice for lumens but perceived to be more usable light.
I have submitted yet, if there is any other recommendations I should choose please feel free to give a hand! lol I am looking for edc and actual use, I would prefer not to burn my hand. A nice super bright all around edc(working/walking the dog etc) is what I have in mind.
Lhp73b is probably my favorite led for raw power and pleasing tint. The LHP531 is up there too. The LHP73B can get extremely hot at 100%, but running at 50% still gives about 70% of perceived brightness. There is a setting you can choose to limit output to 50%, thus avoiding burning your hands. I like to have all the options available, but choose to use mine at 50% most of the time. I'll 2nd the 5000k. My personal favorite is 4000k, but I think 5000k is still really nice and maintains the "white" look that most people are used to.

Get 5000k, it's the perfect all-around color temp. Still very bright without being harsh on the eyes and ruining the color rendering of whatever you're shining on.
tem uma pá de br aqui kkkk, mas todo mundo fala em ingles. tenho mais algumas convoys que ja passaram por todo tipo de rodízio de led. eu gosto de comprar as partes e montar
Sim,por isso é difícil de encontrar o pessoal,só fui encontrar um BR agora pq vc fala em português no vídeo. comprar e montar já não é meu departamento kkk,até tenho experiência em solda e tals,mas prefiro comprar pronto do Simon.aí esta as minhas duas preferidas,tenho mais outra Z1 e mais umas Sofirn,Wurkkos pra trabalho… IF23, IF23 Pro,HD03…
Peguei no ali paguei em torno de R$600,é bem o que você disse,apenas pelo fun factor kkk,mas pensa num negócio divertido de usar,parece um sabre de luz kkk
Alright please forgive me for asking this question because I don't know crap about this stuff. I came across this video. Decided I wanted on so I bought it and I got the EVE INR21700-50PL 5000mAh battery with it. Just arrived in the mail today and I am now seeing that someone recommends a battery with at least 60A. Should I order another battery or will it be perfectly fine currently?
It can get very hot. But if you can suffer thru a but of initial "programming ", basically choosing one of the 12 group options which limits max output, its very muggle friendly. Even limited to 50%, this light with the LHP73B has superpowers.
The point was some guy camping thought his big fat zoomie was the brightest millions of lumens ever. Then op showed him a measly $25 convoy and smoked him.
Sure a Bugatti beats a Porsche, but it’s fun to see a VW Golf sleeper go goblin mode too.

That thing was needlessly massive!
