OK lets have a poll to see what people want for mounting options, maybe we can influance what gets made... Should be multi vote so you can choose board sytle and wiring...

How do you want to get your Cree MC-E?

1s3p to give an asymmetric hotspot.
I guess a star with 8 pads.

4S - this will mean huge possibilities when it comes to small DIY bikelights. As long as there will be made some good not-too-large optics of course..

Definitely 4S because there would be no worries of bad die matching like the P7 and it could be run off of drivers that are already out there.

Mounting isn't really my concern, but I'd prefer to do the wiring myself. Mounted on a board that give you solder pads away from the emmiter would be nice though.
For me, 4S, plus mounted in _some_ way.
This things have way to much connections to be comfortable otherwise.
(Well, perfect would be a distribution board where you can just re-set some jumpers to change between 4s,4p, 2s2p. Doesnt need any electronics for that...)

4 independant is the best way so the end user can choose the configuration best suiting their application. 4S is the next best way as there are no inherent disadvantages as with 4P or 2S2P.
+1 for 4 independent!

from the vote, it seems that some people still prefers the 4P setup :thinking: we have P7 for that right?
4 Independent is best i think
Thanks.

Are you looking at the same results as me??? 4s is up at 43% 4p is only 10%
I figure I will have to do my own if I want 2 * 2s which I have a plan for...

So we are going to redesign our star board to suit. Possible options with the current 4 pads would be to leave one set of +/- as a single pad for 4S and the other broken into 4 to address each die so they could be S/P as required
any other thoughts, suggestions ?

You should also make a third board that does 4P just as another option for those who want that. I can see your 4 independent being most popular.

My option isn't there- 1s 3s.
I'm thinking one 18650 with a linear dropper powering 1 die at 350ma regardless, with a boost circuit sending 0/350ma/700ma to the other 3 dies depending on how much light you want, with a 3mm thick copper tube containing everything- optic plugs one end, and an end cap for the other end, witht battery/drivers/emitter/switches in the middle.
Not sure if I can ever make this light a reality, but coupled with an R2 to helmet mount in a similar design with a narrower optic (6 deg?) would be pretty awesome

Im thinking like this
I don't realy see how you could make this work... You need some way of opening the 4p conections when you want to use 4s and vice versa you can not have both connected at the same time, if you do what you have is a short with no die at all...
The best you could do to be flexible with 4 pads would be 2 * 2S which would be striaght forward to use as is or as 4S or 2S2P
Sorry Jarl I could not do all the options in the poll as well as adress the board style bit. I had never even considered your 1S 3S or znomits 1S 3P but I suspect you would have trouble getting someone to do a board that style. Of course the raw led or a 4 independent board will keep you both happy which is one of the cool things about this over the P7....
Personaly I am keenly waiting to see what optics become avalible. I still have not found anything online althiugh the original press release indicated that some were on show at the show...

4 independent would allow you to wire it in any combination you want :twothumbs

IF this is going to be mounted on a star or board, it woudl be a crime to not have separate pads to allow the user to determine wiring, as soldering EIGHT separate leads on an emitter the size of an XR-E would be a major PITA.

Hear, hear!
I gave up soldering a regular XR-E emitter, so I can just imagine how it would be like soldering an MC-E emitter..
