help with DIY LED grow lights

I'm planning to build a very small light for a small veg table/cloning station.  I've bought 3 Cree xml2 10watt 6500k cobs and some blue 3watt cobs to encourage more leaf and less stretching. Has anyone ever done anything like this and if so are there any videos of wiring these cobs in series with the blues on their own channel to switch off and on. Thanks

Hmmm. Not many into the LED's....  Well I've started building it and when I can figure out how to post photos I'll post pics and specs as it comes together

Looks pretty solid. How are you going to drive them? Presumably not at full pelt. And what space you looking to cover? 6500k has plenty of blue in it any way (cool white) i doubt you'll get much stretch. I've been trying 5000k in veg and seen some squat growth! Nice chunky heatsink too.

I am going to drive them with a little 12 volt .8 amp plug in transformer.  I have it up and running.  It's not that bright so I'm going to just use it for clones. If I find another 12 volt 1.5 amp transformer I'll update it.  I'll post some pics.

Here is the finished light.  Sorry for the delay, didn't think anyone was interested.  It will only be used for a space that is 3 feet by 20 inches.
