I don't have a driver for it, but the only one I know of that would run it reliably is the HBFlex, which is $40... This is just for mock-up, if I do it it'll be in a nicer SRK as host, and a cool white array instead of the warm (3500k) shown, and those reflectors are beat-up leftovers, I have new ones to use once the dimensions are all figured out.
How long would it take to get hot enough to vent the cells? :evil:
That would be quite the flooder!
Probably the most interesting mod in BLF history? Go for it !
Supfire m6 host. Yes. Definitely go for it
What are the specs on that LED? (Need to know before I say yes!)
30v/3A, "100W". http://www.ebay.com/itm/290927494120
I'm sure they don't do the actual claimed lumens, but I can tell you they put out more than enough for lighting an entire room. I used one for a gooseneck work lamp and it's too bright to the point of being painful. I had to swap it out for a 50W with a dimmable driver.
With 30 watts to the LEDs an SRK will reach 60C inside the driver compartment in three minutes…
I’d say no, it just isn’t big enough for the power. It will also be pulling well over 30 amps from the batteries.
Should only take around 6 amps worst case, of course it'll have to be converted from 4P to 4S. HBFlex won't run at less than 7v input anyway.
edit: that's at startup with fresh cells, if you could manage to somehow run it long enough to drain the batteries at 3v/cell it should only draw about 8.5A.
The SupFire M6 has a thick shelf for the emitter to sit on, with pretty darn nice heat sinking. I’d go that route.
Yes
But I don't have a M6... I do have a SRK with a 1/4" thick aluminum plate pressed in and already at the right height for this setup to drop right in. :bigsmile:
Go for it, maybe put a short FL aspheric lens in front of it to try and capture and redirect some of the massive flood of light you are going to get.
f* it, why not lol
If you are going to do it, at least put a decent LED in there… a Bridgelux C9000….
Go for it. My suggestion would be to underdrive at 30 or 50W first. Gotta solve the heatsinking issues.
You can go nuts later if it works. 
Bridgelux RS is surely nice but 50.8mm square, this needs to fit in a 48mm round hole. How much of the corners can be chopped off before it's unusable? (and $55 vs. $8 is a bit ridiculous, especially for something that's basically nothing but a party trick)
Did someone say party? Bring on the party favors!
Why are you worried about heat? Like you say, it's a just because I can mod, so go for it!
Looks hilarious, I think that’s all the reason you need to do this!
I have the cool white version of that led and the same reflector on order from dx, haven’t been able to find anything to drive it yet. Thought it was jut a novelty really 
Go for it!
if it works make sure you build a second
ill sell my kidney and send you the funds
I use this to drive a 36V MT-G2 from a 4S configuration.
Might be hard to hook up with your set-up, but I had a different hardware config.
Run's a bit more than 20W. Actually more like 28-29W.
It'll save your batteries and your hand.

Since you’re running budget build here, running generic LED, use cheap driver. Here’s a $2 generic boost driver (LM2577 equivalent) - runs 30W. Huge range of voltage - so easy to configure.
Fitting it in, well, your problem :). Should be no issue if your host is SRK size or equivalent.

30W is proof of concept. Can do parallel driver + diode for extra juice later ( maybe 3x30w? Heck, that still will just be $6 ).
