Thanks for the info. The combination of rainy weather and underemployment leaves Richard Cranium with far too much time on his hands to investigate these matters.

The purpose of my investigations was to engineer a cheap "ball cap" led light with a custom remote battery pack that would run it at near "full gate" all night.

In this other case, I substituted 4xAA @1.2V NiMH for 3xAAA 1.5V Alkiline to see what would happen. The Energizer light is supposed to be 1 watt led and appears to produce something near 40-60 lumens. I base this on the fact that it has a bright spot near the intensity of my Stella 120.

However, as one of you notes, this light is all jazzed up with a PC board and extra options for other lights on its body. The main led draws over 30 mA the flood and night modes a little less. Anyway, I figured if I sub in "AA"s I would get better run time. I'll check out the CP forums.
