A couple months ago I purchased a mini mag LED. I was immediately impressed by it's output, being brighter than the single cell Nite Ize retrofit, but the slightly additional length made it get in the way when I sat down or drove my car. A few weeks ago I was just playing around, and found out that the mini mag LED fits perfectly in the sheath for the original mini mag. Upon discovering this, the mini mag LED has become my everyday light, brighter than the original and with none of the inconvenience of the longer sheath.
