I had a high dome KL1 which I have been EDCing on my E2e for a month or so. Today I bought an E1e from a fellow CPFer so that I could use up all the used batteries from my M3. I was happy with it but I wanted to see how the KL4 would perform on an E1e body. Then came my friend.
My friend had a KL4 which he EDC everyday on a Vitalgear body, similar to the TW4 package. We compared the 2 lights. Both seem to output the same amount of light but my KL1 throws just a little further because of the optic. The KL4 has better flood. Now remember this, we are both using a near depleted battery with mine being slightly weaker. We swop batteries. It turns out my KL1 is still running strong and bright on his battery but my friend's KL4 is a whole lot dimmer on my battery. After that swop back our batteries again and my KL1 still output the same amount of light like as if it is using a new battery.
Why is this so? Does this mean that on a single cell light the KL1 has better efficiency than the KL4? I am confused since there are so much hype about the KL4's efficiency improvement using an E1e or Vitalgear body and no one is talking about the KL1's efficiency.
