Nailbender kindly agreed to sell me a "linger special" basically two Cree XPGs mounted on one PCB (in Parallel)

He advised I purchase the 8x7135 driver to power these fully (1400ma to each)

However I would like at least Hi/Low or Hi/medium/low NO STROBE or SOS.

I did some research myself and ended up with these Candidates:

http://kaidomain.com/ProductDetails.aspx?ProductId=5595
Hightlights:

- Designed to run a parallel wired MC-E LED
- Modes: High/Middle/Low
- Buck current regulated circuit
- Output Voltage: LED voltage
- Current output: 2.8A
- Output level: 100%/30%/10%
- With a mode memory
- Dimension: 19mm

or
http://kaidomain.com/ProductDetails.aspx?ProductId=9534
Output Voltage:
2.8A(High)~ 1.38A(Middle)~0.25A(Low) --at any voltage level from 5.5V to 13.2V---Current regulated
Caution: No more than 3 D-size Li-ion Batteries (4.0V~12.0V) for protection this LED board

I'm planning on running this off of 2x18650.
Would either one of those be better then the other? or is there something else I should be using?

1st off dont believe the specs.
3 hours off 2 18650's? No way. Maybe half that!
I wouldnt even be so sure they are different drivers.
Anyway I have used that driver ( or one that looks just like it) with MC-E's P7's and even 4 XR-E's either 4P 700ma each or 2P2S 1400ma each ( although this setup needs higher voltage than 2 18650's)

Anyway it is a good cheap driver but YOU NEED TO HEAT SINK IT.
I simply drill a hole in the heatsink the slightly bigger than the inductor and thermal glue the board down.

Great glad to know i'm on the right track. I've searched thru the forums but I can't locate a place to obtain p60 style heatsinks.

Any ideas?
