simple way converting ultrafire C8 throw to flood (pic)

1.09 is really low. That's more like a "medium" output level if the measurement is accurate. Are you sure you're using a decent quality meter and good thick leads? See my test with my two meters and different leads on my KD C8. I now only use my Elenco meter with homemade test leads made from 12ga wire and banana plugs from Radio Shack. I get results consistent with other users now.
