Surefire Dual Fuel Batteries- for all 2x123 batteries lights?

[FromMyColdDeadHand]

I have a few 2x123 SF lights stretching back 15 years. I see the dual fuel ones with the rechargable 18650 or the 2x123 batteries. Why can't any flashlight, like an EDCL2-T, use the rechargable batteries?

They can, but the 18650 is larger in diameter than the 123 and would not fit in a EDCL2.

For 2 cell flashlights surefire makes rechargeable 123s, or if you need larger capacity, a 16650 will work in a lot of 2 cell bodies.

Thanks, have some ordered now

On most, I see a slight lumens hit due to the lower voltage.

Also, Oveready, and Sky Lumens offer a boring service, where they bore out the flash light body to accept 18650s. I am currently waiting for my 6p to return.
You could also order an E series body already pre bored from Lumens Factory.
