I'm finding more uses for Energizer L91 AA Lithiums. They cost $20 for 12 at Sam's ($1.67 each), so they are not inexpensive. But given the way I use my lights for amusing myself, i.e. short bursts followed by many nights using different lights or not playing with them at all, the primary lithiums make sense. They also make sense for car and emergency flashlights, given that they last a long time and can withstand cold and heat. NiMH's need constant upkeep (recharging). You also have to factor in the cost of the NiMH chargers, the electricity for the chargers, and the time and hassel involved.
I have a modified 3D Mag in my car with 9 L91 AA's in a fivemega 9AA-3D holder, WA 01166 potted bulb, litho123 .377" aluminum reflector, and Borofloat lens. I also have a back-up PT Surge with 6 L91's and 2 dummy AA's (bulb will instaflash on more than 6 lithiums). For play time at home, I put my 9AA Tesla-6 head on a 2D Mag body with 8 L91's in a modamag 8AA-2D holder. Same brightness as with 9 NiMH's.
The bunny's seem to work fine up to a 2 amp draw (e.g. WA 01166). They get VERY HOT when used to drive a WA 01185 (>3 amps). Battery Station AA lithiums don't seem to have the same output and runtime that the bunny's have. They are cheaper, but shipping needs to be factored in.
Just some observations.
EDIT: DO NOT use the bunnys in the PT Surge. After less than a week, I opened the light and the bunnys had swelled, partially peeling back the wrappers! Don't know why
. The bunnys in the Mags are still happy and functioning. The PT Surge is air tight. Could it be that the bunnys need to breathe?
