Most Flo's are spectrum specific instruments and fail to provide the warmth of tungsten or HMI. If comfort is the issue, Flo's would be my choice. If acquiring the best color saturation is the issue, then tungsten or HMI.
I'm new at this, and looking at the cool-lux light. does this work as good as any other light?

The cool-lux light is a pretty good light. What exactly are you using it for? "as good as any other light" really depends on the job you need it to do.
