Owned one and sold it shortly after a few months. While it is a nice looking light, the beam is kind of weird. It has a tiny hot spot but with a huge spill. The hot spot is not very bright and can't really throw far. Not surprising, looking at how the reflector was designed. The beam is slightly yellowish, not really in the range of neutral white tint but close. I wonder what SF was thinking when they came up with that reflector design. Accessing the 3 outputs isn't that difficult. All I need do is tap through it quickly to get to where I want before locking the clicky switch down. Overall it isn't a bad or lousy light. Still gets the job done. But at the price that SF is charging, I expected more.
After more than a decade of being an SF fanboy and having bought about 70-ish SF products, I finally came to the conclusion that SF has been taking steps backwards in their R&D and quality assurance as of late, or maybe after Paul Kim's stepping down as the chief engineer. The Stratum was built shortly after Paul Kim had stepped down and it is one of the first to be released without the classic knurling synonymous with SF products.
I am assuming you are getting a resale piece since it is no longer in production? But my advice is to spend the money on other lights. I used to avoid Chinese made but recently decided to try one brand out after obstinately refusing to touch that brand for many years, Fenix.
I can't believe I actually bought a Fenix flashlight! I went for the PD35 TAC (Tactical Edition) and honestly it is way above the Stratum in terms of the UI, number of output selections, and also highest output. There is no doubt the Stratum has a thicker body and is definitely more robust, but then Fenix is no slouch either. They are well known for making reliable flashlights. I know that, but I avoided them purely because I always hated the name (sounds like some mythical creature), and because it is made in China. I finally got that mental block away and I can only tell you that I just love the Fenix PD35 TAC so much it is in my rear pocket everyday for when I needed the power. It outshines my P2X Fury as well.
