Just received one of these pre-installed in an L2P host, and I love it. I went with a Nichia 219B. It's both my first Nichia and first P60 setup, so I don't have a lot to compare it to, but I'm enormously impressed with the customer service I received even before I ordered. We swapped half a dozen emails while I was trying to figure out what I wanted, and Randy at PFlexPro put in some extra labor to make sure I got exactly what I wanted. I ended up with a 411-lumen high, a 0.8-lumen moonlight, and very nicely spaced modes in between.
Along with the package I got my output graph, some extra copper wrapping, a set of spare contacts, a sample of the potting material and one of the plastic dowels he uses to remove drop-ins. The attention to detail all around is really impressive.
