There have been about three posts that explain the increase of claimed lumens. And to a large part these have been ignored while the incorrect ones have been taken as fact.
The increse in the spec is due to the recent CONSISTANT availability of higher bin LEDs. SF was likely still getting a mix of a few Q2's and maybe even P4's in the initial production of the E2DL - it HAS been out for a while! I had one myself (not 200L!) a long time ago. Lately they have confirmed (to themselves) that they are RELIABLY getting higher bins through
testing that they all now meet 200L. The one tested by MrGman in his IS was over 200L, but even he later said it was brighter than others he saw, and other people tested E2DLs at 160-ish lumens. Lately they are testing higher on AVERAGE, and it is due to better bins in ALL of them, not just a few anamalous ones.
It is more likely than not that a new E2DL will be brighter than an old (more than several months old) E2DL.
You CAN NOT rely on what a random SF customer service person tells you. If they were always right, the new KX3 has a P60 module and SF would release product as promised instead of 9 months to 2 years later.
Has anyone confirmed that Surefire actually increased the output or just remeasured and relabeled the E2DL? What changed? Marketing ploy or physical change of LED?
