I should point you to the fact that using the same led I do should give you an extra-ordinary light power:
CF7DS can drive 4 channel, Luminara drove me on the new XPE2 that should be VERY efficient + the fact you can choose your colors (on Quadpod PCB) leads you to a BBBW configuration: 3 blue dice working permanently and a white one for the FOC
this is what I'm about to achieve, I just had to make Daren at JQSabers lathe specific heatsinks (thank you you saved my project Daren!) but as I asked it very late I will, I'm afraid, got them to late before making a 3week trip to Quebec, the following test will be made mid-july.
For my part I will use one PCB per color (RRRW, GGGW, BBBW and a RGBW for the fun) I just have to disconect the PCB and replace it.
