...how long can we expect the KL5 to run? Will it be brighter and if so, wouldn't we expect it to run for a shorter period of time on maximum illumination? Just curious.
It's interesting to read about your ideas.
Sweep stake?
But seriously, the size of the L4 limits it's output and reach. I suspect that the larger 5W bezels from SureFire will have higher output and longer reach.
