this coral seems odd in regards to preferred placement I have heard all extremes and everywhere in between. typically I hear the ones in lower light look more intense red/orange and in higher light it gets a salmon or pinkish hue just my experiences and things I have heard from other reef heads sorry no PAR readings
I have mine about 12" to 14" under a 250 watt halide. The color is pretty close to Nanofin's colony and about the same size. It also gets some good flow and has similar projections. It started slowly but since encrusting the growth has been pretty good.
I have mine 12-14" under 400W 14k Metal Halides. I haven't had any significant growth since acquiring my frags several months ago, though they have gotten "lumpier". The color is still a bright red/orange though.
