3aaa to 1x18650 doable?

[Northernflame]

Hi.

I've often noticed that the 3aaa led fl's don't have as much bettery life as a single AA (rechargable of course).

Are there any kits to do such a conversion?

Thanks.

I was able to mod a 3aaa light with an 18500, the 18650 didn't fit. Light output is very bright now with way longer runtime.

An 18500 will fit into almost any light that uses 3xAAA, just as lasercrazy stated.
