Basically they are dual 4up XR-E R2 BFLEX cutter kits 14deg, 4deg. I've gone for puke green (actually flourescenet yellow in daylight) rather than polished aluminium and the backs are homegrown Carbon fibre. Excuse the postmans elastic bands as I havn't decieded how to mount it to the bars yet! Total head unit weights are 240g (120g each).
The main feature is on the fly Master slave select (the wires hanging out of the back of the unit with jumper connects). The slider swtich in the centre is dual gang and disconnects the push button and connects the wire link from STAT+ to SW1. This basically means it can be controlled independently or switch birghtness via one button (useful I think if you have a wide/narrow like this). Just pop the jumpers together and flip the slider to slave on one unit.
The bflex driver is recessed in the slug which makes for easy mounting (pinned down with blobs of silicon)
The MCPCB is thermal epoxy Asetec silver to slug. I spread it with a stanley blade and it gets a nice thin even spread. - barely paper thin but good contact.
Finally my dodgey scematic.
Having the Master slave select on the fly made the internal a lot more difficult than it needed to be. Also in hindsight I would not have bothered with t he addiditonal ON/OFF but it makes for extra protection.
Currently it's lashed up on 18cell AA MiMH (22v) pack sitting under the saddle (560g). I've swithced on and tested - fully working. I'll try get some beamshots soon. li-Po battery to follow.
Thanks for all the help on LED's etc here as this is my first build working with LED's. Also i'm open to bar mount suggestions. Where do you all get those large dinotte style o'rings in the UK?
Also I was thinking maybe using 2 narrow (4 deg) optics and diverging the beams slightly on a mount to give 6-8deg spread - dumb idea? Or maybe machining down the 14 deg cutter like you did Trout!!

Almost forgot ...edit... they are bright lights!!!

I had a few problems with my 1st attempt at wiring a bFlex
