Today:
I thought I'd design a light for ..."MATCH"
It's pretty simple .
It has a huge car battery housed in a body that is in the shape of a Gas Can.
It has a flexible neck and ends with 5 xml emitters .
1 mode 5000 lumens
Comes with all appropriate warning stickers
and a sandwich ...(He's looking a little thin)
Note to self: "Make sure I swallow my Rice Krispies before clicking on a post from Boaz...Otherwise I'll be spending the foreseeable future scraping little beige breakfast blisters off my monitor!"
LMAO...that was pretty good. At 240lbs, I could probably skip the sandwich though 
With that much power he could have a toasted sandwich :-)
Or just forget the LEDs and short the battery - the arc ought to give quite a lot of light :)
Might as well skip the middle man and hook up a couple of LEDs straight to a mobile defibrillator. :D
Should be plenty bright... for a second or so. ;)
Why not the old fashion way with gunpowder? Instant blindig flash. Good luck trying to measure the lux at 1m. XD
Hehe.
Wow... You guys are the greatest! Although I'm not sure if y'all are still designing a flashlight or an I.E.D. (Granted, Charlestt just wanted me to have breakfast...).
This brings up a good point though... After receiving my first xml drop in yesterday and being thoroughly underwhelmed at it only drawing 1.8a, I did a lil' driver swap. I had an extra SB 2.8a just itching for a new home. Once the pill was back together I noticed I had a hard time screwing the drop-in back into the solarforce host...Might be due to too much tinfoil, or more likey because of the band-aids and medical gauze around my fingers (Did y'all know soldering irons aren't just hot at the "tip"?).
Time for satisfaction: Pulled an IMR off the 'ol electron pump, dropped it in the tube, and presto: Instant disappointment. Not sure what all the fuss is about really. I did notice that I got a few more lumens out of it by utilizing the "pitchers throw" grip technique and slinging photons out the end.
After sitting and thinking (and pondering the virtues of Aloe Vera...), I came to realize that Boaz and my buddies on this forum just may be onto something....but the xml's just won't do: After a couple of quick calls to a vendor at work I procured this:
Gentlemen, May I present to you....the future of lighting and the final answer to all these so called emitters (or as I'm apt to say, Wee-mitters...)
The XXXMLBFG-2000: (queue 2001 Space Odyssey intro...)
And here's one of it mocking a 1200lm 2C Mag Mod:
And one more shot of my futile attempt at containing this much LED-Awesome...
Driven at a manly 32v yet only drawing a miserly 2.5a(Who said it's not practical...) it pours out a herculean 5,000lumens. The beauty of it is it only requires 8x18650's... a pittance compared to C4 and shorted Deep Cycles... I figure 5 of these beauties modded together will produce an earthbound light of an intensity last seen over Tunguska, Russia back in 1908...and essentially make the Sun it's bitch.
I'll post some beamshots when the project is complete (pending the outcome of the skin grafts and any legal injunctions...)

What exactly is that last thing because i don't seem to follow completely here...
are they A LOT OF xml emitters? or something else?
Looks awesome though :d
yu
There are quite a lot of silly power LEDs designed for industrial lighting and the like. They tend to need huge reflectors to focus the beam. That thing is a 80+ watt device, the battery pack for an 80 watt device is huge or the runtime is measured in seconds. At XM-L efficiencies, that thing would be producing 12000 lumens, not 5000.
Haha, nice! I think I'll trade in my flying car for a nuclear-powered XXXMLBFG-2000 with a small form factor and programmable modes.
Al Gore, quit dicking around and get on it already. I know you invented the Internet and everything but, really, what have you done for us lately? :D
Don you're quite astute. It's an 80w LED in an industrial enclosure I'm using to replace 400w metal halide lamps around our mill. This is the quintessence of pure flood. Not the most efficient by todays standards, but 5k lumens is still 5k lumens...
How many lumens do the metal halides put out? I assume it is in the same ballpark as the LED so the 80% reduction in power consumption can't hurt.
And the heasinking is adequate i guess, otherwise the life of that led will be low...
When I took it apart I was mildly surprised that the led is just epoxied to the back of the enclosure. Not necessarily a bad thing, since it's a NEMA 4 cast aluminum housing. Cast into the back side of the housing are large fins...seems like it'll do the trick. I've had a couple installed now for just over a month continuously running. So far so good.
Don, I don't have a spec for the metal-halide lumen output. Eyeballing the difference between the two, I'd give a slight nod to the M-H. This may just stem from differences between tint and reflector shape though... Yes, power savings is considerable, not to mention the reduced downtime the mill incurs from not having to swap bulbs over critical equipment.

Yeah, the big saving is not having to change bulbs. I've been up on a cherry picker in a factory roof doing this. You can't get anything done while bulbs are being changed. Hope the LEDs last a lot longer than the bulbs.

Heh..you and me both, or I'll have some expaining to do on cost justification for these (@$300ea).
