I'm experimenting with P60 drop-ins now, looking for throw. I'm getting around 6800-6900 lux with SST-50's and about 6900 with an M60. I'll have a Dereelight 1.2A pill in a few days, and hopefully my R2 emitters will arrive to go into a 1.4A pill already built and waiting. I'll post the results soon.....
I have the Solarforce MP Pro 1 with a UCL and I'm getting 54,000 lux. It is awesome. Will be building a 1.4A pill for it too. Based on preliminary testing of the 1A vs 1.4A drivers I hope to be getting over 65,000 lux with it. It is odd looking on a 6P host, but looks great on a Z2 and fits the hand really fine. It is a bit heavy (10 oz loaded), but it would make a great "hammer" for anything you choose to crack open. I consider it my Number one Tactical light. Can't imagine a better light as a defensive tool with it's blinding hot-spot, heft, and extremely sharp bezel.
