Below is a table showing INITIAL output in estimated lumens from my lightbox, on various battery sources:Written by MichaelW on 02-21-2011 08:17 PM GMT
I would love to see how it handles the 3 volt primary cell, 14505.
As you might expect, the TI 3V 14505 primary lithium cells perform intermediate to the other approved battery sources.
As an aside, these new AA-shaped primary lithium cells are designed for lights where the same circuit is used in the 1xAA and 1xCR123A models. That way, you can predict their output by looking at how the CR123A runs.
In AA-sized lights where there is no 1xCR123A data to compare to - yet 3.7V Li-ion is officially supported - you would expect intermediate output levels, as shown here. But you are also taking a calculated risk in using a battery source that has not been officially approved by the light manufacturer.
