Questions about emitters...

Sorry if this is a repost, I tried the search tool and couldn't find my answers...

I'm building my own P60 module using DX parts, I want it to be a thrower primarily. I will be using 2xRCR123 cells.

Will this 17mm driver...

Fit in either of these P60 modules? They don't list the critical to function dimensions at all

Can someone recommend a driver that truly pumps out 1000mAh, and is compatible with 2xRCR123? I will be using this in a stock 6P (all aluminum).

Will a Q5 emitter perform better (brighter & farther throw) than a P4?

Thanks!!

Yes, should be brighter. No, not more throw (with the same reflector), at least not this much more than our limited view would notice.

But a very good reflector would make WAY more difference!
the best reflectors for Crees are the ones from the Sandwich Shoppe, but they are also expensive.
The parts You coose are very cheap and thats how they work

Throw means not neccesarily a wide, but a deep reflector with small beam degree.

Except for the machining and the driver, this DX offering is, what You should do to the 6P: http://www.dealextreme.com/details.dx/sku.9634
a hell of a small thrower, good sinked, running on the better battery (in the 2 pc. CR123 size class)

PS: I dont like those inserts, because they can not give the heat away in sufficient amount. With an emitter running at 1 A --> even worse.
In a mod (better and intended for longer lifetime than just an insert) the led has to be placed onto a thick aluminium sheet, which itself is press fitted into the flashlight body.
in case of the 6P: there is the part inside the head where the diameter gets smaller to the battery tube. This forms some kind of "seat" for the press-fit sinking plate.
