This is the multi-mode 250-lumen light. I have once measured it's run time with 4 freshly charged 2,500 mAH NiMH AA cells. On high setting (250 lumens) it ran for over 6 hours before dimming to about 50-60%, which was still plenty bright. On a low setting, which is perfect for up-close use, as a light in a small closed area, such as a boat, car or a room, its power consumption drops down from 1.1A to ca. 50 mA - the run time must be measured in days! |
