Bruiser-12000. Has four Big Bruiser circuits, powered from four 26650 (or four 26700A). Draws 10 amps, 168 watts. 12000+ lumens. Heh heh…………
Been a while since I posted anything here on BLF. Just been busy. Anyway, thought I’d chime in with what I’ve been doing lately.
I don’t really have a web page for Bruiser-12000 as of yet. Just been making ’em and selling ’em. It’s listed on my shopping cart. Have both the shorter version with twisty on/off/momentary type switch, and also a much longer version with two switches up from for high/low power selection.
Very nice looking light, and it will impress twice: first when people see you carrying it around, then at switch on when there is the wall of light that they still could not have imagined coming out of something so small
I read this too, but you never get 168W at 10A from a 26650 so I asked again. Doesn’t make sense to use just four batteries. sorry I forgot where I am here
This beast needs a 4S3P 18650 tube or more…
I’m not sure if you are understanding, so I’ll comment about it. Four 26650 in series is about 16.8 volts. Some 26650 can easily discharge 10 amps, and the 26700A Moli battery can discharge far more than that, and 10 amps is easy. Nominally speaking, wattage is 168 watts (volts * amperage = watts) (16.8v * 10 amps = 168 watts). Especially the 26700 can maintain 10 amps for the duration of discharge, but good LIMN 26650 can also do the same.
The Bruiser-12000 is massive both in size and in shear mass of metal, and very easily keeps the LEDs at a very safe temperature, and the entire flashlight never gets more than warm. Weight is around 4 pounds. This is similar to Kong-12, but a bit smaller diameter head, and uses 4 Big Bruiser circuits instead of 12 individual stars, and only 4 26650 batteries instead 11 or 12 18650 batteries. I was able to reduce the overall size because of improved battery technology and my triple LED circuit boards. I also am able to get the price way down from $1500 of Kong-12. I still offer Kong-21, but have been considering a Bruiser-21, which would be 21000 lumens, and around 290+ watts .
I read a post somewhere, someone questioning why flashlights are getting so bright, and suggesting things are getting out of hand? Well, yeah, things might be getting out of hand, maybe?
Why would someone want a 12000 lumens or more flashlight? Well, uh……… Why do some people need a BMW or Mercedes or Lamborgini, or ………………
These decade old moly cells seem to be the holy grail, no voltage sag and constant voltage of 4.2V. I only know the 3.7V IMR cells but the Canadian are well known for their high tech batteries….
Maybe the old M5 is the correct comparison, superb car but way to small gas tank.
Every 200km I have to go to the gas station…
The 27600A Moli cells I get were purchased have been stored in cold storage as specified by the manufacturer, to keep power loss to a minimal, so their performance is at or close to being new. However, a good LIMN 26650 will work just fine in Bruiser-12000, Bruiser-9000, Big Bruiser. (Brutus Maximus only pulls around 3 amps as the LEDs are in series, but it also uses 26650 batteries.) A 26650 with protection circuitry like 4sevens or some others, will not work as the batteries protection circuitry cuts off the power way below the level these flashlights require.
Run time of Bruiser-12000 is short, around 20 - 25 minutes on high. Run time on low is about 6-10 hours, depending on the low power setting.
It was always my understanding that LiFePO4 batteries were the only Li-Ion batteries capable of a very constant discharge voltage. Do old Moli cells REALLY hold a pretty constant 4.2V on discharge the way LiFePO4 holds a constant 3.2V? And if so, why would they stop making such a battery in favor of those with a more typical (for Li-Ion) dropping voltage curve?
Hi Wayne, first of all I must say this is an insane torch!
But I just wonder why wouldn’t you make this light to use 5*26650 so that it can undergo buck regulation, which can maintain the high output until the batteries almost depleted?
