I am considering buying a Surefire KL1 LED assembly for my E2e. I am unsure about what brightness level to expect, as well as the color of the beam. I have read here that there is a blueish/purplish color to the KL1. Is the KL1 more or less purplish than the Brinkmann Long Life LED 2AA, which is the only light I have to compare it too? How much brighter is the KL1 than the Brinkmann 2AA LED and the Surefire L1? Would the Surefire L1 be a better choice over the KL1? Thanks much for your help.
