"Fat Star" Octa 8x SST-90 Colossus Led Flashlight @ 18.000 lumens -more beamshots-

Hello,

instead of doing something serious with my money like going to Ibiza, I put some parts together,
in the beginning there was this lathe and a piece of aluminium:

...later it looked like this, thanks to Piet from Frankfurt:

...and here are all the parts for the whole light together:

...the SST-90 emitters, connected together in series and glued to the
massive heatsink for the modamag 4" Turbo Head:

...the modamag configurable battery adapter with 8x IMR18650 cells, I will use
a stock Mag switch to power this light- not sure, what will happen in use...

"Fat Star" Octa 8x SST-90 Colossus Led Flashlight at about 18.000 Lumens, the whole light:

This current I measured with 8x AW IMR18650 cells fresh from the charger, I wanted to get
nothing more but 9amps for 8x 2250 lumens = 18.000 lumens, but I got this, my camera had
some problems to take the photo, down left is the heatsink with the working SST-90 emitters.
I hope some resistance will be added when the flashlight host and the switch will come
in between and current will be reduced...

...please excuse blurish quality, I could only take one beamshot, then some security from the hotel showed up and asked me "friendly" to leave...

13A through that I'm guessing 18 gauge wire in the head?
Loord...something will be red, just not the heatsink of the batteries [they are red to begin with :nana:]

I can't wait to get home to see the pics you have posted. Internet at work does not allow me to look at pics. :confused:

At 12 minutes of runtime it won't heat up much I guess.

What is its mass?

... Also waiting for beamshots.

wow. you can scorch and burn a whole football stadium with that thing.

Fixed that for you.

Holy nice build! I am curious, though, stock mag switch? 18G wires? Will they handle this?
Is there a low beam, like 6000 lumens or something?

Oh, and BEAMSHOTS!!!!

Doesn't it feel good to be there, on top of that hill?:twothumbs

This thing is begging for a photo like the publicity shot of the SR-90 being compared to a car's headlamps.
