I did it! The royal blue is beautiful. And the diffusion with the 18 degree lense almost seems to work better; at least the blue seems to have less contrast between emitter end amd the tip. The only issue I have with the Tri-Star is that 700 mA isn't enough for more than one LED to be in saturation. I forget who mentioned the current-behaviour in a parallel circuit, probably a tired me, but we had it backwards. So tonight I'll be upping the current draw for the LEDs and experimenting. When I can get purple, yellow, and cyan (or whatever the third.color mix is), pics will be coming.
