I have a pretty new Solarforce L2P with an R5 drop in. Been using it fine with two 123 batteries. I tried a 18650 today. The light works, but sometimes the brightness drops and then goes back up to full. It's not that bad but noticable.



The new 18650 battery works perfectly in a Solarforce L2 light with the same model R5 drop in, however...



I even tried a 17670 in the Solarforce L2P just for kicks (since it's similiar to two 123's, but just for flashlights not bored for 18650s) - but it flickers.



So, I'm back to using the two 123 primaries in this particular L2P. Any ideas why it doesn't work - yet the same brand new 18650 works in an L2 Solarforce with the exact same model R5 drop in?



I was actually going to get 1 more 18650 for both of these Solarforce lights, but apparently that plan won't work.
