Looking for cheap 18650 extension

I want to try AA cells in place of 2×18650.

Ebay has them for $4.89 shipped (LINK).

Anyone know if this C8 body can be used instead? It’s only $6.68 shipped (LINK).

I understand that whether 4AA will actually work electronically depends on the driver, but in terms of length, is 4xAA close enough to 3×18650 to fit in most lights?

There are extensions made for C8, here or here  These should fit C8 body well.

The option for a longer C8 that runs on 4 AA cells is very intriguing. I sold my C8 and may have to get another one so I can have it as an emergency light if things go south again.  Let us know how it works out for you.  I don't see why it wouldn't. Wink
