Great Review as always!
But the P-bin is just a gimic. It's same flux as the old SST-90 N-bin.
Which means P-bin SR-95 has the same flux as the old N-bin in SR-90 2 yrs ago, improvement would have to come from difference in driving current, as the SR-95 reflector is smaller.
Looks like Luminus couldn't produce the real P-bin, so they cheated. At the moment, I can't even find a place that has the P-bin for sale, Only N bin available which is the old M bin 850-1000 range, this really sucks!
2009 Binning: 1000-1200 Lumen = N Bin
2012 Binning: 1000-1200 Lumen = P Bin
