looking for a balance of spill and throw, I have a novatac 120p with a k2 emiter upgrade. I am looking for somthing like that but on a larger scale, with my surefire Z2 light as a host. I was thinking the P60 / D26 Cree XM-L U3 dropin from customlites would be cool, with the orange peel reflector, but I am open to sugestions. Why is the P60 / Luminus SST-90 dropin $30 more, it has less output what am I missing? Also, I see the max voltage for these is 6v so I could use 2 primary cells in my surefire host, but if I want to go rechargeable should I use an 18650?
