*k!!!
Oh, and as they say…
“No pressure.”
We used to go drink beer under the landing lights off Bachman. And do other stuff there… I think that they frown on that now.
I tried lighting up a cheerleader… she vaporized.
I really want to test it at a school playing field. But it looks like most of them are kept under lock and key these days… can’t be having the kids having fun, you know.
Added some pics to posts 2 and 4…
20,000 lumen random strobe took care of those pansies… anybody know how to get barf out of a flack jacket? J)
Look forward to see the beam shot of this monster.
So does this driver have a strobe or not? (I really hope so...)
It has MANY different strobe and blinky modes. The firmware is basically the same as my SRK driver. The three main strobe modes are a slow 10Hz mode, a fast 16 Hz mode, and the random strobe that varies the timing and intensity of the pulses. There are also a couple of bike strobes that don’t blink full off, several beacon modes, and the programmable Morse code mode. You can program the driver to select the modes/order that you want to use.
Added a wall shot to the 4th post…
Cool, roughtly equivalent to the 4 T5 fluorescent 4 footers I put in an 8’ fixture. 17,000+ lumens. A very nice room light! Orrrrr, a great bug attractor for going fishing! 
Very nice wall beam shot! Now get that thing outside and take some “let’s light up everything” beamshots 
Great job on the finish work. If you water proof the array it looks like it would make a dandy hot water birdbath. Or maybe even deep fry the turkey. That is some insane amount of power.
Thanks for the latest update. Is there other members sitting and reading about this light with a smirk on their face and every few seconds a guttural noise emanates from the bottom off their throat out through half opened smirking lips?
Funny you should mention that… I had it sitting up outside (turned off) for a while. When I came back, a cockroachy thing was in the bowl. Let there be light! And He saw the light! And it was good! Smokin’ good. J)
+20,000
Edited post 2 with some actual voltage vs current numbers for the assembled light. At 7A drive level, looks like it does 21,000 lumens. I can’t get it in my sphere for a real test. To get 7A, I fully charge the battery pack then use the “storage charge” function on the charger to drain the pack to 3.94 volts/cell. I have run the array at 10 amps (briefly) and it survived… doesn’t seem like a wise thing to do for long.
Good mod! I miss the golden and silver eras of rock when I heard this LED Zeppelin track.
I did a little more testing at 7 amps/220 watts. It heats up rather fast. The fan is going full blast after a minute or so. It starts going into thermal stepdown after a couple of minutes. Seems to level off at around 6 amps/180 watts.
Looks like a an lamp lol. Outdoor shots PLEASE!
I'm sorry if this has been covered before, and I must admit I am being lazy, but how does this compare to say - the amount of MT-G2's (or XM-L2 etc) that you would need to have an equivalent output?
I mean - are discreet emitters like that more efficient than these arrays, and if so would it be a better bet to use multiple emitters rather than one large array? I'm thinking here of the drop LED efficiency as the input power increases. More LEDs at lower power > less LEDs at higher power.
MASSIVE generalization of course, but I think you can understand what I'm rambling on about...maybe 
The MTG2 is a multi-emitter array. Arrays are more efficient than single emitters because each LED is driven less hard than an equivalent single emitter. The C9000 has 81 (?) LEDs in its array. When driven at its published drive level, each LED is around 1 watt.
