My L4 was one of my first lights and long one of my favorites, although it has gotten much dimmer over the years.
Prime posted some great photos. The differences between 30 and 45 lumens or 45 and 60 or 60 and 80, etc., are large and easy to see. I thought lumens had to double before the eye would pick up the difference. What's up with that?
That's what some people here on CPF say. I have been hearing it for years, but when I had my first KL4 and compared it to the newer KL4's the difference was quite pronounced. I think that our eyes, tied in with our computer like brain, do well discerning light.
