Last night, after putting the kids to bed, Linda and I took a nice hour-long walk around the neighborhood at the shore (my father-in-law stayed at home with the kids). My wife took my seoul=modded Gladius, I took the Gotham. After 10 minutes my wife turned off the Gladius and we used the Gotham solely. WOW, this thing is bright, and the beam is so well balanced too. Great color. The neighborhood has no street lights, so we really got to put the Gotham through its paces. It threw for a great distance, yet when held at hip level it put out a bright, large flood that was probably 7' or 8' across when aimed 3' in front of us on the road. We played with the four light levels and found that level 2 (second lowest) was about ideal for a walk.
It did get warm on high after an running for about 30 minutes (the other 30 mins were on level 2), but only warm. It was comfortable to carry too.
