Some updates on the throw of these lights: I went out on my front porch again last night and lit up the field adjacent to my house. I'm going to be honest and I hope I don't get anyone's hopes up. The SST-90's throw @2100 lumens is better than the cool white tri-XML @3000 lumens, but here's something to think about: it's very difficult to focus a really huge LED like the SST-90 to throw in such a tiny optic. That said, I'm extremely surprised by the performance of the Ledil Iris optic Wayne installed. It does an excellent job of focusing it into an actual "beam" pattern, instead of the stadium light effect as mentioned by Viper715. The SST-90 does have a narrower more focused beam, but the sheer output of the cool white XML's does compensate for its lack of throw.
With that said, let's face it. Every attempt to date to make a pocketable or semi-pocketable SST-90 flashlight hasn't come remotely close to anything that resembles a hotspot. Heck even XM-L flashlights of the same size (think Zebra SC600) are floody. So it's an extremely impressive and innovative feat by Wayne Johnson to make the SST-90 do something that others couldn't.
Personally I'm hooked with the SST-90 and will be using it as my EDC. In fact I already am!
Just got my warm white SST-90 this morning and I'm going to say this is my new favorite. It's the least brightest of the bunch @1700 lumens, but I absolutely favor the color temperature over my other hi-CRI flashlights. Red/orange/Yellow colors pop out a lot more evenly, whereas the warm-white tri-XML tends to wash out the other colors. Luminus did a great job designing this LED. I'll be taking my nightly walk tonight and see how it performs in the real world. This weekend I'll walk by some dark railroad tracks next to my old high school, will see how it performs in the throw category.
When I have the time I'll do a review of all the different flavors.
