Hi,
I tested the KL3 led module driver from Surefire (old version with finned body).
i used a votage regulated DC power supply and 2 multimeters.
The load on the driver was a XP-G S2 from Cree (heatsinked)
voltage range of supplie for this test : 9V to 2V
The led turn off at 2 volts. the led Vf was between 2.94v@9v to 2.8v@3v
The regulation drop off apear to be at 3.3V (missing mesure in the graph), but notice during mesuring.
For a old driver i feel like isnt too bad, with a wide voltage range from 9v to 3.2v.
The typical current to the led in regulation is 0.46A.
Regards
