Bear with me fellas. I'm new to the CPF. I recently heard from Dan at Tactical Warehouse that Surefire has plans to offer colored LED head options for the L1 & L2. Does anyone have any info on this or a time table? I'm trying to come up with a viable option for night navigation. The F05 Red filter on the L4 is just barely adequate and will eat you alive on batteries if you are out all night. It also filters out so much light that it is working at cross-purposes. I think that I might need an UN-filtered red LED for lumen output with good side spill, but have not yet had the chance to get my hands on the L1-HA-RD. /ubbthreads/images/graemlins/help.gif
