Just a quick question...
Have Surefire L4s always been 100 lumens?
thanks for info, in advance.

To my understanding yes.
When SF released the L4 they're IS was calibrated for incandecent lights,so they basically just low balled a guess at 60 lumens.
Later on they made more accurate tests and changed the packaging to 100 lumens which i think is still conservative.

Ditto...the 2005 Catalog lists them as 65 Lumens.

As I understand it, 1996alnl is correct.
SureFire has used the best LEDs it can. As LED technology improves it is possible to obtain sufficient quantities of more efficient and/or higher output LEDs so there has tended to be a base-line from which performance increases.
With regards to SureFire's LuxeonV lights such as the L2, L4, L5, L6, L7 their initial rating was a ball-park one performed quickly to get the rating into the catalogue at the time. It took SureFire some time to resource testing a sufficient quantity of production samples in order to be confident they could increase the rating.
I believe in general terms one can assume SureFire output ratings can have "at least" in front rather than the ratings be considered a maximum possible value.
