ColtRifle, I have the Terralux TL-100 conversion for the Mag Charger. It produces a very smooth, more floody, than spot beam. The overall output is quite satisfactory. I don't think I'm getting the claimed 100 lumens tho. Seems closer to about 65-75 base on comparison to some of my Fenix lights rated at 50 lumens or so.
No where near the out put of the OEM incand bulb. Its main advantage IMHO is much extended run time. I have not tested it, but the claim is, IRRC, somewhere around 6 hours on a single charge.
