OK, I want one just for the sheer absurdity! Actually, the runtime is insane, and it should be with a battery that massive.

Edit: I have 2 x mj906s lights. Ran these recently on a group ride and the person in front of me said something like, "did someone just turn the sun on behind me?" That is with "only" a supposed 9000 lumens.

BTW, I have lots of other lights (Gloworm, Outbound, B&M, cheapo chinese, Gemini, kLite dynamo, etc). I almost always grab the Magicshines. They represent the sweet spot for me, with reasonable durability, weight, light output, and runtime. YMMV.

Beyond the ohmygosh factor, there are some pretty interesting characteristics to this light and significant differences from the rest of the Monteer family. While it has 5 emitters it isn't 2 spot + 3 flood with max output running all 5 together like all the other Monteers. Instead it looks like it has two entirely separate systems that can't be run at the same time. The first is a moderate power (2500 lumen) "floodlight" with a pretty uniform beam with sharp horizontal and vertical cutoffs that looks like it was designed for road use. The second is a "spotlight" using 4 big honking Luminus SST-70s each of which can crank out 3000 lumen. I guess I see why they don't bother with a combined mode. The carefully sculpted light field of the floodlight would just be swamped by the 12000 lumen spot and not add much other than the bragging rights of slightly higher total output. Maybe this light was designed for someone who needs to ride on the road at night to get to the trail (?)

Another interesting factor is that it appears that Magicshine is learning from its competitors. The new 12000 has app based tailoring of modes like Gloworm and passive flow-through cooling of the light head like Outbound. While I don't need anything like the kind of horsepower this thing puts out it does seem like Magicshine is putting in some real development effort here and this may be a compelling package for those looking for piles of output.
 
I'm not sure who this light would be appropriate for but from the below attached video link light performance looks excellent. Total system weight of almost 3lbs would be a deal breaker for me though. Looking forward to hearing some owner comments.

I think this is a very valid use case for a lot of lights. For example I love the cut off on my OL Road light when gravel riding on paved trails and road but it sucks when I go off road. Similarly, when I ride my mountain bike with my OL Trail EVO that light is great in the woods but it totally blinds people, even on low modes, when I am cycling on my paved trails to the woods...

I would love for @Outbound to design a light that had two modes that allowed you to run road (aka Detour) or trail (aka Trail EVO).

Don’t worry, it’s already in the pipeline. 🤗 but working with a German university for some incredibly cool optics that are beyond my optical capability. Going to take some prototyping for sure but excited to bring it to market.

We had been putting off patenting our designs and stuff since we figured we’d move fast and iterate quick, and that we were small enough Wouldn’t get noticed. Between this and them using the Evo name for another bike light…. Sounds like this got pushed up our priority list.:rolleyes:
 
I can hardly imagine who would use it. I developed our own Lucifer ULTRA 8000lm headlamp so I really know how bright such light is and at that time I swore I will never make any stronger, because that doesnt make sense. If 8000lm is not enough, 12000lm wont be either. The more powerful lamp, the larger battery you need to have some runtime. Keep in mind this is 144wh pack and you cannot travel by air with it, limit is 100wh. For a comparison, aircraft landing lights do have similar light output, although tighter beam. Do anybody on a bike really need intensity like landing airplane?

My background is I am multisport athlete (non-professional), doing mostly orienteering, 5h mountain bike orienteering and 24h multisport races, where you can perform any possible sport during the night, including biking on moderate terrains, trails and roads with any possible conditions (rain, snow, fog) and in my 12yrs racing career I never needed more than 3200lm, usually less than that.

I can see some potential customers as I know what customers buys our 8000lm lamp, but there are not cyclists. For mtb/cycling, usually best ratio of light output/weight/runtime/prize is between 1700-3200lm. In my opinion, the brightest light is not always the best, that 1.2kg of weight can quickly get annoying. I do sometimes even tell my customers not to buy so powerful light they want to as its complete overkill for their needs, despite knowing we have highest profit on them.

Im not taking it down. If you know you really need this huge light output, then its completely ok to buy it.
 
I made a quick calculation and 12000lm with 2h30 runtime is totally unreal! If its 144Wh pack, then 2h30 would results in 57,6W power - that never ever produce 12000lm OTF unless they are using secret alien technology :cool:

Our Lucifer ULTRA needs 62W to get 8000lm OTF! Be prepared that 12000lm is only a random number written on the package, I wouldnt be much suprised if our ULTRA outperforms this.
 
No such thing as too many lumens IME. There might be a practical issue, where you'd rather have the increased battery capacity to run decent brightness for longer, but being able to go max for an intersection is priceless IMO. Also, having a remote to adjust intensity based on speed is extremely nice. If you've ever used a remote, you'll find that you use it like a dropper post, the faster you go downhills, the brighter you want the lights.

To those knocking external batteries. Headlamps are a catch-22. That's where I want the most lumens, I want more of a spot than a flood (not a tight spot, just more spot) and I want it to run the longest, because if I have to run one light, that's where I want it. But the catch 22 is weight, you can't put a big battery up there and then there's the cold temps where you may be able to insulate a remote one. While you can put a bigger battery in a remote location near the handlebar...that's not where you want the most lumens or your primary light...but it's the most convenient for it. So we end up running insufficient lumens on our helmets or insufficient run-time.

So because Magicshine is advertising an efficiency 1.5 times that you measure you accuse them of false advertising? Maybe so, but there are so many variables in electronic design, emitter selection, radiometric measurement and runtime definition that it's pretty easy to imagine this kind of variance in numbers between manufacturers.

Yes, its false, I know it. I write this based on my knowledge. I design switching converters and pcbs for all our lamps over 13 years, trust me, I know a lot about it. You cant get over 100% converter efficiency and its really hard to get even over 90%. There are also optic losses, you lose at least 8% of light there, usually more.

Taking best todays LEDs, you cannot even get close to that figures, thats fact. I made yesterday quick calculation, you can calculate it more precisely knowing its SST-70 but result will be same, either lumens or runtime is overstated or there si pseudoregulation (not constant all the time). Everyone who is in LED field knows you cannot get 230lm/W from LED with this current. You would be lucky if its over 150lm/W. Chinese manufacturers do this all the time, no suprise. But that doesnt mean this lamp is bad, just be realistic with runtimes and light output.
 
Magicshine historically has over stated their output, sometimes by large amounts. Methods differ between models. Some will be close the stated output but only maintain that for 1-5 minutes before starting a steep decline to a level that can be maintained for something sorta close to the stated runtimes. Other models just start well below the stated output, then go into a gradual decline. Pretty old info now as I think the site owners no longer do tests, but wetestlights.com is a good place to verify how some manufacturers lights perform.
