I want to use a pair of them in a LF D26 HO-9 bulb (9v)!
I've never tried the LiFePO4, are they worth compared to the rcr123a?
I'm asking because HERE I get SHIPPED a pair of AW's rcr123a by 18$ or the Lifepo4 for $16...
Think the LiFePO4 are also lower voltage - typically 3.2v instead of 3.7v - so that might be something to consider.
Yeah, a 9V lamp won't be too bright using a pair of LiFePO4's...I'd stick with the 3.7V RCR123's.
