I am intrigued by the Nitecore SRT5 and SRT7 for its ability to adjust output light from about 1 lumen all the way to about 750 lumens. I now have a Fenix E12, which has 8 lumens, 50 lumens and 130 lumens output. I used the E12 mainly at around 8 lumens, but sometimes I find 8 lumens too bright. In that case, I wrapped my hand round the flashlight to lower the output level. Right now, I am looking at the Nitecore P12, SRT5 and SRT7. How often do you find a need to use the continuous variable output as opposed to the fixed steps ones?
