Well.... so far, I like the Thunder a bit better than the Storm, only because it appears that it will run with 4xCR123 batteries as well as 2x18650 rechargeables, and the Storm appears to run only on the 3x18650 rechargeables (please correct if I'm wrong). I just think it is important for a light to be able to run with primaries for those times when it's needed, even though the extra runtime afforded by the 3x18650 platform is very attractive.
And, while I'm very happy that they are offering these lights with a lower level, they would be darn near perfect with the addition of a good solid 100-200 lumen middle level.
I mean, that 100 lumen range is what I find myself using quite a bit for walking about, doing things at night... and having a light that would do that easily, with the added bonus of being able to kick in the 510 lumens for the odd times that you wanted it, but also having the 30 lumen low for close-up stuff (or super long run times)..... well.... that would make for a darn near perfect light.
Anyway, these look to be excellent additions to the Wolf-Eyes line up, and I'll look forward to hearing how folks like them.
