OUCH !
I understand that driving LEDs on +12V with resistors will be a disaster ... OK !
Now, i have to make a choice on which current source i will use on my project ...
I found some useful things on eBay like this one (but it is used...) : http://www.ebay.com/itm/90W-LED-Driver-Power-Supply-Constant-Current-HPLED-/160654435132
In fact, i would prefer to buy it, but i need a one case at all, i just don't want to have x modules around my led panel.
Only one would be a nice thing :
