I just installed a TerraLUX TLE-6EXB in my 3D Maglite, and I'm pleasantly surprised with how nicely it upgrades the old doorstop. I figured I'd go ahead and upgrade my 6D as well, but the 6EX version gets some "iffy" reviews on Amazon. Anyone know what would happen if I installed the 6EXB (intended for use with 2-3 cell units) in my 6D? Will I fry the emitter? If there are any other upgrades out there for less than $30 that would work with my 6D, I'd be interested in hearing about them. Thanks.
