Have any of you compared these two lights side-by-side? How would the beams on these two compare? Would there be any appreciable difference between 200 lumens from the E2DL and 170 lumens from HDS (I do a lot of morning search warrants in dark apartments and I want as bright/disorienting light as possible)? Any pros or cons between the two? Any other pocket carry units I should look at?
I don't have an E2DL, but I have an LX2, which is quite similar, and also an HDS 170T
The LX2 (and I'm sure the E2DL) is noticeably brighter, and I can certainly spot things in the woods at the edge of my property slightly better with the LX2. (This isn't a huge difference - you can see it, no doubt about that, but it is NOT huge.) This is over a ~100-150 yard range, and I'm in the country where it's *dark* - there is no light whatsoever around me. (No streetlights, nothing, I'm fully dark adapted when I do this - sitting outside in my observatory with no lights at all for 3-4 hours.) This is likely in marked contrast to what you'll deal with (coming in from a lit street to a dark apartment with very poor dark adaptation).
In your situation, the E2DL might have a light edge - your eyes aren't likely to be very dark adapted, so the extra bit of light might help. However, the difference is NOT large, and I'm totally comfortable walking around my property with the HDS 170T - skunks, coyotes, etc aren't going to be sneaking up on me. (I'm sure you'll deal with less pleasant critters sometimes.)
The HDS is a very versatile light, much more so than the SF. The SF light is good at what it does, and that's it. You can likely get as much or more useful runtime from the HDS as the surfire, but it won't be nearly as bright. (You can throttle the HDS down, and it throttles itself down from the 170 lumen mode after 10 seconds.) If you NEED full brightness all the time with max runtime, I guess SF probably wins here. That said, the way HDS throttles down is *really* smart, and you probably don't need 200 lumens all the time. Even after the light steps down, I can easily see to the edge of my property.
The user interface difference between the lights is something to consider too. I really like the HDS, but it is somewhat "fiddly". You can make it do all kinds of stuff, and using it is pretty natural, but I'm not so sure that would be a feature under extremely stressful situations. (Although you could program it to just have 2 modes, just like the SF I believe.) It depends on you and how you use the light I guess. I'm not a LEO, so I just can't really judge the types of stressful situations you're in, and I have no experience with them, for which I'm quite grateful.
They are both excellent lights. I find I use the HDS more, but again, my application is way less critical than yours, and hey, it's newer.
