(Update: images added to main product page)(Minor Update Feb 2013 @ end of review)
I work overnights, and a portion of my duties involves pavement, facility, construction and even fenceline inspections, and responding to a whole host of pretty random "stuff" that pops up out in the boonies, generally away from any lights. My lighting requirements are mostly close-in and short range, where I value a flood light with good area coverage vs. a narrow beam with great throw.
As a quick aside, it seems to me somewhat foolish to post a flashlight review on Amazon without a single beamshot. But because you're here, I'm guessing you're already probably well-informed by all the user input on the various flashlight forums such as CandlePowerForums (or similar sites), where flashlight advice and comparison beamshots abound. If not, by all means Google it to see how this rather expensive piece of equipment compares to other brands and models. At the time I'm writing this, XM-L LEDs seem like the brightest way to go, but flashlight technology advances at a steady pace and there will be something either brighter, smaller and/or cheaper coming along.
I was reading up on Fenix's 2200 lumen XM-L equipped TK70 flashlight when I stumbled upon the Olight SR92 beamshot that "spoke to me" and, well, here we are. (You can look up the same set of beam shots by searching for > taschenlampen-test tk70 sr92 x-21 < and look for the series photographed under the overpass -- it's from a German-language forum.)
And just for comparison's sake, I've been getting by with a 540 lumen "Little Friend" by Elektrolumens -- short & pudgy, lightweight and pocketable, with a good beam spread but handicapped by short run times.
The SR92, in contrast, is quite the beast. It tips my scale at a hair over 2� pounds, so I won't be putting it in my pocket or hanging it from my belt. It does come equipped with a shoulder sling strap, but if that's not your style you can remove the two eyelet rings and set them aside for use later. The head of the light is a bit bigger in diameter than your average sized coffee mug (maybe closer to a thermos?) to accommodate the three XM-L LEDs, each with its own reflector. The shaft of the light (battery + endcap) is just long enough to hold double handed, so it's not ridiculously long like a 5-D Maglite, and actually looks quite proportional and not out-of-place in my large but not exceptionally large hands.
It's unfortunate that the balance if this light is just a little bit off. The head is too heavy or the battery too light -- take your pick -- and so the balance point is far up front, about a half-inch behind the blue on/off button. So when I'm walking with it, the beam likes to hang downward. I find that I really have to choke up on my grip to keep it pointed straight ahead for casual usage such as this.
The light output of the XM-L LEDs is spectacular. I mean, when I show up to an incident and everyone else's flashlight is "what they brought," turning on this thing is embarrassing. The light's a spreader, not a thrower. My feeling is the claimed 1000 meter (3200 foot) throw is a bit of a stretch (I have some expansive areas marked off in thousand-foot increments in which to check this capability out). This light easily outshines my Tahoe's stock high & low beams at medium distances, and gives my vehicle-mounted searchlight a run for its money, especially close in.
The spill is excellent (as attested to by the beamshot photos from that German website I referred to earlier). A flashlight with a bright, focused hot spot will wash out everything around it, but with this light doesn't have that problem. No doubt, the SR92 has a hot spot -- but its spot is wider, dimmer, and the halo around it is brighter and bigger, making washout less of a problem. I can shine it out my Tahoe's window, more-or-less straight down 4 feet or so to the pavement, and really see a decent sized area -- not just the individual fixture or pavement joint / defect I'm interested in. And when I'm cruising the fenceline from a car's length away, this light easily lights the barbed wire on top, the tension wire below, and all the fence fabric in the middle, versus my spotlight which lights only one of the three and washes the rest out. And stand this light on the floor on its tailcap in a dark room, and you'll be impressed with how well it can light up an interior space during a power outage.
Take this out to an incident, though, and it really lights up the area. Fluid spills, vehicle breakdowns, medical calls -- you name it, if it's dark out, it puts a lot of light everywhere from just a few paces away. It can make a vehicle interior seem like daylight from a few paces back.
I haven't had a need to use the strobe mode in an operational context, but I've tested it by "blasting" an unsuspecting co-worker from over � mile away. Even though he was driving away from the beam, the seizure-inducing 10Hz flashing caught his attention immediately, prompting him to stop and circle back. I can see this being useful in beaconing fire/ems in to an incident, though I'd be careful to point it at the ground and not in the driver's face.
The construction of the SR92 is top notch. No battery rattle. The light is solid. The knurling isn't "sharp" for bare hands, but it's most certainly grippy. I don't see any defects in the machining or the anodizing. The black is truly black, with uniform color and no streaking. The graphics appear to be laser eteched, not decals.
I don't like the single on/off button, and would prefer more than two brightness levels. I am concerned about the durability of the blue rubber material covering the actual power switch -- it feels as if the spring resistance of the momentary switch is too strong, and will ultimately cause the blue material to fail by tearing a hole into it. But that remains to be seen -- I see Olight has been using this design on their other lights, so I'm just going to continue to use it normally and presume it'll all be fine.
Through the single button, I can power the unit on and off with quick presses, switch between the high and low modes with longer presses, change to strobe mode with a quick double press, and lock the flashlight out with a very long press. The light powers back up in the high or low state it was powered down in, and only flashes in high mode. Three quick presses bring the light back from lockout mode.
The battery minder built into the end cap tells me exactly what I need -- a press of the button lights one to four LEDs to indicate the approximate charge remaining. As much as this feature is appreciated, I have to tell you that I find it unbalanced that Olight justified this extravagance for such a minor (yet handy) feature, yet opted for just the single power button. For comparison, I have rechargeable power tools that have nearly identical 4-LED battery level indicators that illuminate for a few seconds every time the power switch is pressed. Quite frankly, I'd rather have been given a second button at the head for output mode changes.
Speaking of the battery, the run times have been excellent. I don't use the light enough in any one shift to run the battery down completely, and it's such a treat not to have to worry about conserving juice. Though for heavy users, Olight's replacement battery packs simply screw on to the head, so it's always easy to carry spare capacity. The instructions recommend recharging after every use, but obviously that's up to individual requirements.
In use, in moderate temps, I can't tell whether the active thermal management mode has kicked in. That is to say, I can run on high continuously, and when I'm done, the head of the light is just barely warmer than ambient temperature -- warm, but not hot. I have yet to observe a step down in brightness. Supposedly, the active thermal management kicks in after 3 minutes of use on High, and reduces power (if necessary) to keep temps in check to avoid any damage. What's not clear to me whether this three minute timer resets when I cycle the power, or if it's strictly temperature dependent.
The included carry case is "cute" but overkill (I'd have gladly traded it for even a $10 cut in price), and it's not really aluminum (so maybe it won't dent?). However, the case does reflect positively on the quality of the light inside.
To summarize, this is an exceptionally well rounded light, one that's moderate in size and in throw, but is bright and offers great run times. Fascinated by pure output numbers, I came so close to the long-throwing 2100-lumen TK70, and while that big light would have generated a lot of ooohs and aaahs when showing it off to the crew, I think ultimately I would have been unhappy with it in the close-in situations where I typically use my light.
(Update Feb 2013) this light has been serving me SO WELL. Just came back in from the field after using it overnight to search out some pavement discrepancies and inspect repairs and striping. The wide beam is so useful for this close-in usage -- I just wish the thing were lighter for holding it out of my truck's window for long periods. Battery life (total time) is still an unknown as I never run it continuously for long enough to even begin to estimate, but I've never managed to deplete a charged battery in the course of a work night, and charging is relatively quick. The battery maintains its charge over long weeks of non-use, too, which is greatly appreciated for those unanticipated events. Still lots of positive comments from the variety of folks I work with -- and still the brightest star on our site.
