White light colour rendering trial circuit

Thanks to Geoff for sharing this circuit with us. He decribes the circuit as "a simple way of panning between led colours, amber and cyan, to give white light with control over how warm it looks".  Will temperature control overcome colour rendering objections, he asks?

He was spurred on by a recent LED Luuminaries post - Why can LED not yet rival halogen?
