I understand Richard from Cool Lights is considering building his "HMI alternative" light using the Blue Line fresnels. I apologize for not knowing exactly what Richard's plans for this light are, but my limited light knowledge forces me to simply call them HMI-alternatives... ask him for details 
Apparently the Blue Line 650W have a flicker problem which seems to be attributable to the wiring... I guess Richards lights will have his own wiring so this problem will not carry over. Right Richard?
Also, can you explain again, possibly in simpler terms, what type of lights these will be? Also their tungsten-equivalent outputs and anything else you can share to give us an idea of what the specs you are considering?
