Hello everyone,
Please help me decide between these two. I am stuck for a couple of reasons, mostly due to my lack of knowledge of batteries.........
The H31Fw can take a "lithium primary" (CR123A) OR a rechargeable (RCR123) "Li-ion"
The H31Fw's specs are listed here, and it has a slightly higher output than the H51Fw.
"H31Fw Floody Headlamp CR123 Neutral White"
High: H1 180 Lm (0.9 hrs) or H2 98 Lm (2 hrs) / 4Hz Strobe
Medium: M1 35 Lm (12 hrs) or M2 19.6 Lm (23 hrs)
Low: L1 4.1 Lm (3.7 days) or L2 0.4 Lm (21 days)
Light output are out the front (OTF) values. Runtime tests are done using Panasonic CR123A lithium batteries. Runtimes are usually much shorter with rechargeable RCR123 (16340) batteries, especially with protected 16340s that have higher discharge cut off voltage.
Battery: One CR123A lithium primary or RCR123 Li-ion rechargeable. Batteries are not included in the package.
The H51Fw can take 3 different kinds of AA's: 1.5V AA (NiMH, lithium or alkaline) but it has a slightly lower output than the H31Fw
(according to the specs) and it also says that "14500 Li-ion batteries are not supported" It's specs are listed here:
"H51Fw AA Floody Headlamp Neutral White"
High: H1 164 Lm (0.9 hrs) or H2 82 Lm (2.4 hrs) / 115 Lm (1.7 hrs) / 4Hz Strobe
Medium: M1 25 Lm (10.5 hrs) or M2 6.5 Lm (26 hrs)
Low: L1 2.0 Lm (3 days) or L2 0.16 Lm (16 days)
Light output are out the front (OTF) values. Runtime tests are done using Sanyo 2000mAh Eneloop AA batteries. The 164, 115, 25, 6.5 and 2.0 Lumen output levels are current regulated. The 82 and 0.16 Lumen output levels are PWM generated.
Battery: One 1.5V AA (NiMH, lithium or alkaline). 14500 Li-ion batteries are not supported. Batteries are not included in the package.

My three Questions:
1) What is better? A RCR123 Li-ion rechargeable? Or a AA rechargeable?
2) Do the specs on the H51Fw AA indicate that it does not support any kind of rechargeable battery at all?
3) Is the higher output of the H31Fw enough of a difference to choose it over the H51Fw?T
That pyramid did not come out how I wanted it to.
