I see that the E1Ls' runtime on high is 8.5hrs with a rated output of 45 lumens. The L1s' runtime on high is a mere 1.5 hrs with a rated output of 65 lumens. I think we can agree that Surefire underrates the output of their lights. But the L1 only puts out 20 lumens more yet its runtime is roughly 1/7th that of the E1L. Why is that? Has anyone done a runtime plot for the new L1s? I wonder if they underrated the runtime too. Just doesn't seem right for the output. In my feeble mind, at 65 lumens (which is probably 85 -90 ish in reality but the point being) It should go for at least 2 SOLID hours before dropping out of regulation. Anyone else see where I'm getting at?
