I did the SE (U3V) in a KL4, it gives off a HUGE flood...NO throw. I have a TWAK in my KL4 now, way better! I liked the SE, but I have other lights I use for flood. I juiced it up to 880ma thanks to Chop, he sent me some resistors and in 10 minutes I was ready to throw some photons, burn some retinas, light up the night.....you know what I'm saying /ubbthreads/images/graemlins/hahaha.gif
