That Mini-Mag run time graph is great.
But I wonder what happened to the SMJLED's?
Seems the consensus around here was that the Sandwich Shoppe version was better than the "other one". 30 hour run time on alkalines was a standard often quoted run time expectation. My Sandwiche Shoppe SMJLED modules draw around 120ma of current from 2AA (3000ma) alkaline cells.
This is in keeping with a run time estimate of close to 30 hours.
I don't see how they could fade out at 8 1/4 hours while drawing such a low current. Low batteries in the test Mag?
Or maybe the Sandwiche Shoppe and Lighthound SMJLED's got mixed up?
Getting a multimeter with DC current measuring capability was the best thing I ever did.
It clears up many a strange situation by giving concrete current draw numbers from which one can extrapolate a good rune time estimate.
