A little help for my newbie info

[KRS1]

Hi

I was just browsing on KD and found some info such:

Power consumption & Runtime:
High: 12.6v @ 810mA 2.5 hours +
Med: 12.6V @ 360mA 6 hours+
Low: 12.6V @ 30mA 73 hours+

does 810 mA tell me know much this LED give lumens?

ITs Q2 LED btw.

Care to share?

Thanks

810mA is the current being fed to the LED. The more current the LED gets the brighter it will be. Per the Cree XR-E Data Sheet, the output at 810mA would be about 190% of the output at the "normal" current of 350mA. This other data sheet lists the Q2 "normal" output as 87.4-93.9 lumens, so the output at 810mA should be about 166-178 lumens.
