    The Olight SR90 Intimidator is the first light I’ve tested with the long-awaited Luminus “Phlatlight” SST-90 LED. What makes this LED so interesting is that it currently has the greatest output (lumens/watt) and the lowest thermal resistance of any LED on the market. Of course, this kind of power comes at a price – the SR90 has a built-in rechargeable battery base that is the equivalent of six 18650 batteries, and a hefty thermal mass to handle the current.

    Is this the first LED to give HIDs a run for their money? Scroll on, gentle reader …





    The SR90 comes in a presentation carrying case with metal hinges and closing flaps. Inside, in cut-out foam, you will find the light disassembled into its main components (head and battery case/handle) along with a charging power cord and transformer, shoulder carrying strap, spare o-rings and manual.

    SR90: Length 335mm x Width 97mm (bezel)

    Ok, this is not a pocket light! The massive head and 6x18650 power pack bring a certain amount of heft. Although I don’t have a scale that can measure at this sensitivity, a little over 1.5 kg feels about right. Of course, that massive reflector should also translate into pretty decent throw …

    Fit and finish are excellent on my sample – there are no chips or marks in the anodizing. The gold-colored rings used to anchor the shoulder straps have some wobble along their length (i.e. not perfectly flat), but seem to be held in place fairly securely (you can rotate them to adjust the exact positioning). The SR90 manual says they are stainless steel, but they look more like brass to me.

    Lettering is sharp and clear, in bright white against the dark black gloss background. Labels have thoughtfully been kept to a minimum (I think we all know we shouldn’t look into this light when it is on).

    Ridge detail is fairly high on the handle, so grip is good. This is important, given the weight of the light – you wouldn’t want to be dropping it.




    The battery compartment/handle comes with a contact cover (for use when not screwed into the head). This is a good idea, as you wouldn’t want to short a six-pack of 18650s. Presumably, you could also purchase additional battery packs, as they can be charged independently (not sure if Olight is planning on making these available).



    The charger attaches at the tail-end of the light (just under that rubber protective strip – similar to what you will find on a lot of camera ports).

    Also on the tail is a battery read-out gauge. Press the bottom button, and up to 4 green LEDs light up to let you know the relative charge status of the battery. Along with the no light condition, that means five possible states - each of which is linearly distributed along charge capacity (i.e. 4 lights means 80%+ power remaining, 3 lights is 60-80%, 2 lights is 40-60%, 1 light is 20-40%, and no light means less than 20%).

    Unlike some other lights that use a built-in battery charge indicator, the SR90 seems fairly accurate – as long as you only test when not running or charging the battery. If the light has been in use recently, you will need to wait at least a few seconds after turning off/disconnecting in order to get an accurate reading.



    The tailcap is removable, which adds hope to me that separate battery packs may eventually be offered for sale. It would be great to be able to pick up a "spare" cell/handle to carry off with you ...

    The light can tailstand with the tailcap installed.




    The head is where the action is, of course. The bright blue button is used to activate the light and change modes. The switch is a reverse clicky, and doesn’t require much force to activate.

    UPDATE: As HKJ points out, it is not really a reverse clicky - it is a momentary switch that is programmed to turn the light on/off when you release it. As such, there will a small standby current drain, but it is probably insignificant.

    You can see extensive heatsink fins all along the head, which should help with heat exchange. You can also see the contact point for the battery compartment at the base of the head.




    Hard to get a good pic without reflections, but the massive smooth reflector is gorgeous. Perfectly smooth, this should provide extensive throw with a wide spillbeam.

    And of course, at the heart of this beast is the new Luminus SST-90 “Phlatlight” LED. I’m looking forward to running this emitter through its paces.

    To begin, time for the requisite white wall hunting. Obviously, the SR90 was not meant to be used up-close on a wall. But I’ve taken a few different kinds of shots to show some general principles (e.g. beam dispersion, overall output comparison, tint differences, etc.).

    UP-CLOSE BEAMSHOTS:

    Since the closest comparator for the SR90 is a HID, below is close-up show showing a comparison between the SR90 on Hi and my Titanium Innovations L35. Distance is about 0.5 meters from a white wall.





    Again, this is only to show the differing beam profiles – note for example that the L35 HID has a much wider field of illumination than the SR90 (or any other LED), and has an off-white warm color temperature (4200K).

    To compare to the 2x18650 multi-emitter class, I have taken some shots of the SR90 on Lo. Distance is about 0.5 meters from a white wall. Note that these were taken at different times for different reviews, so are not necessarily exactly comparable (i.e. distance to wall varies, etc). They are only to help provide a general overview.





















    As you can tell, the SR90 does not reach a focus at 0.5m. But I think you can tell that the spillbeam width is wider than just about any other high output LED light in my collection. Beam tint is also a pleasing premium cool white on my sample. And as remarkable as it seems, the SR90 on Low (i.e. ~30% output) is a pretty good comparable to many of my (previously) high power LED lights.

    OUTDOOR BEAMSHOTS:

    To better compare the throw and spill of the lights, here are some outdoor shots focused on a point ~ 10 meters from the lights. Again, these were taken at different times for different reviews, so they may look a little different (e.g. I planted a tree at the end of last summer ).

    First, the SR90 on Hi, followed by the L35 HID and my cheapo SunForce “1M candplepower” incan (the latter or equivalent you can typically pick up at any automotive store for <$20):









    Both the SR90 and L35 do an admirable job of lighting up my backyard. Again, the L35 HID has a noticeable warm tint (~4200K), and is a brighter overall. The cheapo “1M candlepower spotlight” has a warm and highly distorted beam (i.e. more tighly focused with less spill, but with a lot of artefacts and distortions).

    And now to compare the SR90 on both Hi and Lo to the 2x18650 multi-emitter LED class:





















    Again, the SR90 on Lo is pretty comparable to many of the 2x18650 multi-emitter lights on Hi.

    LONG-DISTANCE BEAMSHOTS:

    FYI, HKJ has included beamshots of the SR90 along with his other high-output LED and HID lights. I urge you to check out his excellent round-up comparison of these big guns.

    UPDATE: Finally got around to doing some additional long-distance beamshots, to show you how the light compares to others in its class.

    Please see my recent 100-yard Outdoor Beamshot review for more details (and additional lights).








    User Interface

    The SR90 has a very simple interface: press and release the blue button, the light turns on (and you get blinded if you are not careful). Press and release again to turn off (assuming you can still see what you are doing).

    While on, press and hold the button for 1 sec to switch between the Lo and Hi output states. To activate the “hidden” full-power strobe mode, do a quick double-press while on. Repeat these steps to switch back to other modes.

    The light has mode memory, and retains the last output setting for you turn it back on.



    Full-power strobe was measured at a highly distracting 9.5 Hz.

    I was unable to detect any sign of PWM with my setup. This means that either current-control is used for the Lo mode, or it uses PWM and the frequency is above my detection range. Either way, you won’t need to worry about it.

    Testing Method: All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for the extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.

    Throw values are the square-root of lux measurements taken at 5 meters from the lens, using a light meter, and then extrapolated back to estimate values for 1 meter. This is my standard way to present throw on these types of high-output lights, as the beams don't really have a chance to fully converge until typically several meters out

    Since some of the other lights take a couple of minutes to settle into their regulated output state, output and throw numbers are taken after 2 mins of continuous runtime.

    I can’t provide direct lightbox values for SR90, as it won’t fit in my milk carton lightbox (same goes for the 1M CP spotlight and L35 HID). Instead, I have estimated lightbox output based on a comparison of ceiling bounce numbers to other lights where I can measure both. For runtimes, the larger lights are positioned an inch from the opening of my lightbox, and I adjust the recorded values to the estimated levels based ceiling bounce relative results. This is NOT meant to provide hyper-accurate estimates of output, but it does give you a reasonable good idea of relative performance over the runs.

    Throw/Output Summary Chart:



    First off, there is no denying that this is BY FAR the brightest LED light that I have ever seen. In fact, the SR90 Lo mode, which is rated at ~30% max power, is pretty close to many “high output” MC-E/P7 2x18650 lights I have tested. Indeed, throw of the SR90 on Lo pretty much beats all of the other MCE-E/P7 competition on Hi.

    Of course, on Hi is where the SR90 really shines (pun intended!). Olight claims it can throw as far 1000m (i.e. 1 km!), and I believe it could at least approach close to this (note I haven't tested it myself). While it doesn’t seem to match the L35 HID in term of overall output or throw, it certainly is closer to an HID than the previous generation LEDs.

    In terms of throw, the estimated 112,500 lux at 1m on Hi is very impressive (note that I measured at 5m to allow the beam to converge, and then worked back for the 1m estimate). But I do not believe the L35 HID really throws twice as far - there are isolated "hot spots" within the irregular center of the HID's beam which the lux meter picks up at 5m. Over longer distances, I suspect you will find the throw difference is not as great as that, but I haven't tested that directly.

    Although my ceiling bounce method is not a perfect measure by any means, I think the relative lumen estimates for the SR90 are petty good as emitter/“bulb” lumens (as opposed to actually measured out-the-front lumens). The 700 lumen estimate for the SR90 on Lo is fairly consistent with earlier generation lights that claimed comparable 700+ “bulb lumen” outputs. And the 2200 lumen estimate for the SR90 on Hi seems proportionately about right, compared to the 3500 bulb lumen estimate for the L35 HID.

    Bottom line, I think Olight’s lumen estimates are consistent with other makers who quote “bulb” lumens.

    Output/Runtime Comparison:




    I am always pleasantly surprised with when my runtimes meet or exceed manufacturer’s specs (at comparable output levels). In this case, runtime on Hi exceeded their estimate (i.e. my 93 mins vs 80 mins spec). Lo mode runtime was pretty much bang on (i.e. my 8 hours 51 mins vs their 9 hours spec).

    Potential Issues

    The SR90 is a large and heavy light – you may find it rather unwieldy to carry and use, depending on your hand size and arm strength (note the specs – it’s over 1.5 kg). I’d recommend use of the included should strap, which attaches to both ends of the light.

    There is no DC car adapter included with the light, so you will need to have a source of AC power to recharge.

    Recharge time for a depleted battery was about 4.5 hours in my testing (i.e. from the point when the protection circuit has been tripped, to when the green light comes on the charging transformer). This is not unreasonable, given the storage capacity of the cell.

    Preliminary Observations

    What can I say – the beamshots and runtime graphs speak for themselves. The SR90 fully lives up the specifications from the manufacturer.

    The SST-90 is the first LED that can truly give HIDs a run for their money. Yes, the SR90 is not as bright as even an entry-level HID, and doesn’t have as wide a beam dispersion pattern. But it still has plenty of output and throw, and brings with it all the benefits of LED light.

    Chief among those advantages are the potential ability to run at wider range of output levels (just two so far on the SR90, but they are well chosen – I don’t need a moon-mode here ). Other benefits include instant-on (without the slow ramp of HIDs over a couple of mins), excellent consistent cool white tint (without the considerable color tint-shift of HIDs during ramp-up), and a smooth and even beam (without the noticeable artifacts and distortions in output and color across a HID’s beam).

    You also get to keep the more traditional flashlight shape here - HIDs require a ballast to act as step-up transformer, adding to bulk and dimensional thickness. Note also that a ballast typically adds a noticeable hum during the operation of a HID light. How noticeable this is can vary with the manufacturer’s choice of material (and the hearing sensitivity of the flashaholic), but it is pretty hard to completely eliminate. In contrast, my SR90 is whisper silent on all modes.

    While the SR90 might look like it is easier to carry, note that the weight remains solidly in HID territory (i.e. just over 1.5 kg in this case). This is due to the heavy-duty power pack (6x18650) and massive heatsink/reflector. This is clearly not a pocket or belt pouch light - unless you enjoy having your pants fall down.

    Aside from the weight and bulk of the light, I can’t think of anything that would be a negative – build quality is extremely high on my sample. The light does get warm in usage on Hi, but not uncomfortably so. And the ergonomic placement and feel of the button switch is good, as well as the hand grippiness (if that’s a word). Price is obviously more than a traditional LED, but relatively cheap by quality HID standards.

    And I really like the fact that the Lo mode of the SR90 is comparable in output and throw to the Hi modes of earlier MC-E/P7/SST-50 lights. Thanks to efficiency gains of running the SST-90 at lower drive levels, along with triple the battery source (i.e. 6-cell 18650 instead of 2x18650), this translates into about 6-7 times the runtime of a traditional 2x18650 light on Hi!

    As for the Hi output, I look forward to the comments of those with more experience of HIDs. I suspect the SR90, and other SST-90 based lights, will drastically eat into the market of lower wattage HIDs. Please feel free to discuss …

    At the end of day, a very impressive first outing by Olight for a SST-90 Phlatlight-equipped light.

    The fact that the SR90 has flat regulation, with that level of output,
    is simply stunning!

    Selfbuilt, many thanks for your valuable reviews...

    Thanks for your very comprehensive review, selfbuilt.

    Its always a bit of a gamble when buying a light upfront before feedback and reviews have arrived, but having done so in the case of the Olight SR90,
    I feel that I hit the jackpot and your review reinforces that feeling.

    My only surprise is that your measurements have the L35 throwing nearly twice as far.
    From looking at the long-distance beamshots in HKJ's comparison pictures, this didn't appear to me to be the case.
    Change is inevitable, except from a vending machine

    I don't think the L35 really throws twice as far - there are isolated "hot spots" within the irregular center of the HID's beam which the lux meter picks up, even at 5m. Basically, I suspect you are looking at an artifact of only measuring at 5m. Over longer distances, you will likely find the throw difference is not as great as that. I'll update the review text to make that point.

    Unfortunately, I haven't had a chance to take them both out to an unpopulated area to test (don't think my neighbors would appreciate shots up against their houses ). HKJ does an excellent job on long-distance beamshots, so I would tend to trust his views.

    Nice review, and thanks for the link to my comparison.

    I have a few comments:
    You write that the SR90 has a reverse switch, that is not really correct, it has a momentary switch and it is programmed to turn the light on/off when you release it. The momentary switch is required due to the way the UI works. This type of switch will have a small standby drain (It is the same for the battery meter), but the drain is probably insignificant.

    You guess about the weight is very good, my scale says 1585 gram.

    I concur with you about pwm, it is current regulated.

    The ceiling bounce test of L35 and SR90 does match my ceiling bounce test very closely.
    My website with flashlight, battery and charger information: lygte-info.
    More than 200 battery reviews and 80 charger reviews.
    Compare 18650 LiIon batteries or smaller (RCR123, 16340, 14500, 10450) LiIon batteries.

    Great review selfbuilt!!! I love my SR90, I'm a police officer so I take her to work with me. It's safe to say everyone is amazed by this light. This light is described as a "search and rescue" light so I decided to stop on a bridge the other night over the White River to see the results. This is a pretty dark area, the river is probably 75 yards wide with a steady current. We have a good amount of people that end up in the river for one reason or another. I took the Sr90 out and started to sweep the banks from the bridge and I was amazed!!!! You can see objects along the banks for a very long distance and the spill gives plenty of light in the water. I think it will be very easy to spot someone in the water with this light!!! I am very happy with it, I just need a pelican case to protect her!!!!!!!
    You can never have enough light!!!!!

    Good info about the switch - I've added an update to that section with your comments. It doesn't feel like a traditional reverse clicky - nice feel, easy to operate.

    And glad to see your ceiling bounce numbers match.

    Thanks for sharing - always appreciate the real-life perspective.

    And good point about the pelican case - although the included case looks fairly showy, it isn't really that solid. I doubt it would hold up to much real world use/abuse.

    Great review! This is a high-quality and very impressive item from Olight, with plenty of thoughtful features - for example, the battery SOC indicator, the battery safety/dust cover, and the lugs for attaching the shoulder-strap (at >3 lbs, the shoulder strap will be useful.)

    I would love to see comparison beamshots at a longer distance vs. some HIDs. As you say, it's the first production LED light to pose some competition to them, and I'm sure there will be keen interest in how it performs at long distances.

    1 question: can the battery pack be user-disassembled for replacing cells, or is it a sealed unit?
    Resistance is futile...

    From your lips to HKJ's ears ... He has some great shots compared to a number of HIDs here:

    As near as I can tell, it is a sealed unit. So, you would need an entirely new handle if you wanted a "spare" battery cell. I'll ask Matt if he knows anything more ...

    UPDATE: Actually, the tailcap is removable from the battery pack:

    Great review selfbuilt. The photos of the SR90 in your hand are almost comical...that thing is HUGE!!!

    2200 lumens with a runtime of 80+ minutes on high...WOW! That is just crazy.

    It's big, but then so are HIDs. The SST-90 is a hungry beast, and needs a lot of power. It's also a big LED, so it needs a large reflector.

    The great advantage LED has over HID is the instant-on, compared to the sometimes pretty slow warm-up of HID (Polarion excepted).
    Resistance is futile...

    This light is incredible I can't imagine another word to describe it. It has lived up to everything Olight said it would and IMO because of the incredible regulation exceeds my exceptions. Great review should put many minds at ease and many more minds in chaos trying to figure out just how to afford one.

    excellent review as always!

    i, too, was surprised by the near-perfect flat regulation. olight did a damn great job on this light

    i want one now more than ever

    Can you use the SR90 while charging?

    and

    Great review Thanks SB

    Yeah, this is where hand shots are a necessity - from the overall shape, you would never know how large it was!

    Incidentally, while I have tried to emphasize the weight here, it may not be as bad as some expect. My daughter picked it up last night, and her first comments were that it wasn't as heavy as she thought it would be.

    Good points - although I suspect they went with such a large reflector because they needed a large thermal mass in the head to act as a heatsink, given the current flow. Probably a bit of a chicken-vs-the-egg issue, I suppose - I'm just glad they went with both in the end (i.e. big heatsink and big reflector).

    Oh, and I just double-checked my light - the tailcap does indeed unscrew, leaving you with just the handle portion with the battery inside. Also note the retaining ring holding the battery inside the handle (a similar ring was present at the other end of the battery pile). It is thus possible that you can get it out from the handle (but I don't plan to try this unless Olight give me the go-ahead). It would be great if Olight made "spares" available for purchase, one way or the other.

    I agree - great job on both regulation and runtime, at both output levels.

    I also like the Lo mode output level, given how comparable it is to the previous generation lights. And I'm particularly impressed that they could get more than 6 times the runtime on low, with only 3 times the battery capacity.

    Now I'm just waiting for someone to complain about the lack of a moonlight mode ...

    I don't know if you are supposed to, but you certainly can. I accidentally left it plugged in for half an hour during a Hi mode runtime , and it added about 14 mins to the total length of the run. A bit surprising that it added so much, given that it takes ~4.5 hours to fully charge the light.

    In any case, I don't recommend you do this without confirmation and more info from the manufacturer - I will check with Matt to see what Olight thinks.

    Ho hum, another day, another amazing SelfBuilt review…

    If these dang lights get any brighter, you're gonna have to invest in some welding goggles to do your testing. I bet you spent much of last week with spots burned into your retinas!

    While the M90's performance is stunning, what impresses me most is the power system: by using a laptop-like "smart" battery pack instead of loose cells, we get all the advantages of lithium ion cells, in a manner that's safe enough for the wider consumer market.

    I wonder how long until some enterprising electronics manufacturers start putting their laptop power controller chipsets on round PCBs? The downside, I suppose, is that such smart battery packs wold be model specific, or at least manufacturer specific. Loose cells are certainly cheaper and more flexible, even if they require a bit more care to use.

    Holy bat, cowman! What a review. What a light.

    I can't think of a use for this light cannon yet, but I am working on some kind of rationale for buying it.

    We hope. Laptop packs have hardly been free of failures.

    Ideally, I'd rather see lithium cells bundled in packs with proper electronics to monitor them, and the light manufacturer's label (and reputation) attached to it. So in that sense, this is a positive development. But, the pack is only going to be as good as its worst cell, and the failure of a single cell will mean a very expensive replacement.

    I got to see an SR90 in the wild last night. It was impressive.

    Astonished, amazed, almost surprised, but most grateful for this detailed and long-awaited review.

    Today there is a before and an after in my flashaholic life, now i know that a SR90 certainly will be mine, it's time to order one.

    If Olight decide someday make an aspherical head for this flashlight in 100mm diameter (better than THIS) my happiness will reach the climax. Please, please, please Olight read this

    Thank you so much for this great work Selfbuilt!!!

    Staggeringly comprehensive Selfbuilt. Once again and to no surprise, you've outdone yourself.

    Thanks so much for enlightening guys like me who have neither the time, resources nor skills to assemble such a monument of excellent information.



    Selfbuilt
    As for the Hi output, I look forward to the comments of those with more experience of HIDs. I suspect the SR90, and other SST-90 based lights, will drastically eat into the market of lower wattage HIDs. Please feel free to discuss …
    The SST-90 in collaboration with Olight have pretty much rendered the 24-26W HID light class obsolete. The only slight advantage that this range of HID's can maintain is in their smaller size since it's not feasible for the SST-90 to run at 10A in a light the size of the Boxer24W. It could be done with IMR cells but the run-time on high would have to be actively regulated to prevent damage. I'm sure the next large format single die LEDs will run cooler and more efficiently allowing LED to overcome this final HID size advantage. 35W HID lights may very well be next on the obsolete list in a couple of years if diode surface brightness keeps increasing.

    The spare batteries will be available next week. We actually HAVE them but our webmaster's wife had a baby last week so we're a little behind on these things. They should be available this week.
