Well, since you asked, I bought a Microstream solely to use the body on my LOD but I found the stock MS to be so good that I left it as-is and carried it instead of my LOD. I never used low mode on LOD, it was usually med unless I needed some distance and then it was high. What I found was that my MS was brighter than my LOD on medium (sorry Marduke

) with similar runtimes and had as much throw as my LOD (Q4 BTW) on high. I'm a sucker for throw and didn't much like the floody LOD beam but the MS still has plenty of spill and is one of my favorite beams of all my lights. For $15 I don't think you can go wrong with the MS and I, personally, wouldn't pay $45+ anymore for an LOD.......................YMMV
