Thread: Looking for 1,000+ Lumens & 3 hour burn time??? Recommend

    Default Looking for 1,000+ Lumens & 3 hour burn time??? Recommend

    What flashlight can guarantee at least 1,000+ Lumens and 3 hour burn time?

    I was looking at the 21700 format Zebralight but this review says:


    • 2,740 lumens for 20 minutes and then 900 lumens till 107 minutes (just under 2 hours total).


    So I'm skeptical it could keep 900 lumens for 3 hours.

    1000 lumens for 3 hours means 3000 lumen-hours of light. A good flashlight will convert electricity into light at 120 lumens per watt. 3000 lumen-hours therefor requires around 25 watt-hours of battery. That is more than a 21700 can provide and is at least 2x18650. Minimum.

    There is also the matter of heat. A lot of lights will thermally throttle above 1000 lumens.

    Look for lights that use 3 or more 18650 and you are likely to find the performance you want.

    Go for something like the BLF Q8. It's a 4x18650 soda-can light. Around $50, and it's a pretty-nice light, especially for that price.

    A Malkoff XM-L Hound Dog will run on three 18650s and will give you in the region of 3 hours runtime on 3400mah cells. No step downs so a susatained 1000Lm or so. You'd need an MD4 tube and a 18650 extender from Oveready.

    Unfortunately, that won't work.

    The Fenix PD36R manual includes a graph showing runtime and output at all modes. The only mode it has higher than 1,000 lumens is its 1,600 lumen turbo. From the graph turbo output steeply declines to a max of 800 lumens or so by the 20 minute mark. Then it gradually declines over the next 2 hours to approximately 650 lumens. Then output rapidly declines and terminates somewhere before the 3rd hour. If you do a Google search for "Fenix PD36r Flashlight review". The third item on the list, Zeroair's review, has photos of the manual including this chart.

    As other posters have mentioned, what you want simply doesn't exist right now in a compact single-cell light. There aren't any single-cell compact lights that can sustain 1,000 lumens for 3 hours. LED and battery technology is not quite there yet. If you really must have 1,000 lumens for 3 hours, you could get a multi-cell light, but these tend to be quite large and heavy. You're not going to be able to pocket-EDC a multi-cell soda-can sized light.

    If you really want 3-hours of runtime at 1,000 lumens in a semi-EDC'able format
    your best bet is probably to get something like the 21700 Zebralight PLUS a spare battery.

    Zebralights are known for being extremely efficient with top-notch heatsinking. You're probably not going to find a more efficient compact single-cell light that is able to sustain 1,000 lumens without overheating. Carry that around with a spare battery in a pocket battery carrier. When the cell in the light runs low, pull out your carrier and swap batteries. With a spare battery you should have no problem achieving your runtime and lumen goal and then some.

    I can say that I have personally seen many cheap flashlights which claim very high outputs that are patently untrue. I own a number of 1000+ lumen lights and know that these are VERY bright and cost much more than a few dollars. They also have good colour - warm or true whites without the horrid blue green purple tints and bad beam common in cheap lights.

    So buyer beware.

    Advice is to buy from a reputable specialist brand. Surefire, Fenix, Olight, Nitecore, Sunwayman, HDS, there are many. Absolutely look at Oveready.com 14 for the most amazing lights for people who use them often and depend on them.
    The intended use should guide your choice of batteries.

    Lithium batteries have been a benefit to flashlights because of their high capacity in a compact size. They also hold charge better than nimh or nicads. So they shouldn’t be dead just from standing for 6-12 months.

    Remember that rechargeables do need to be charged with the right type of charger and primary lithium batteries are quite expensive.
    If you use a light only occasionally or may have difficulty recharging, then think about one that uses common AA cells or CR123 lithium non rechargeables.
    No batteries that I can think of like the cold.


    Lastly. You dont always need the highest output. 60 (real) lumens will blow away most of the big old maglights. 200 lumens bounced off the ceiling was enough for a roomful of people to finish their meal during a power cut in a restaurant. 20 is more than enough for close work after your eyes have adjusted to the dark.

    It sems that the Fenix TK22 V2.0 meet what you required, under the safe setting of overheat, the lumens will change aroud 1200 lumens until the battery runs out

    Nope. TK22 won't fit the bill either. Doing a Google search for TK22 review and then checking to make sure the review is for the 2019 version, 1lumen has a review with output and runtime graph.

    On turbo, output starts at 1600 lumens. It then rapidly declines to about 750 lumens over the next 15 minutes. Then over the next 90 minutes output oscillates between 750 and 1000 lumens with average output approximately 875 lumens. After that output declines rapidly to around 500 lumens at the 2-hour mark and then drops off from there.

    Even the 2x18650 Nitecore EC4 doesn't achieve the output and runtime goals the OP is looking for. I think the best option to achieve those goals in a pocketable format is the 21700 Zebralight plus an extra battery in a carrier.

    This is an interesting demonstration of how clever marketing is.
    Even reasonably well informed people are still convinced that their lights are giving them a specified output, when it clearly isn't.
    Clever stuff.

    with intermittent use I get 3 hours or so out of the Acebeam L30. it is however apparently under 1000 lumens, maybe 800 to 950, and which model depends to. I absolutely do get 3 hours though, maybe just a ting more, intermittent. straight use, I've had about 2 hours and 20 minutes. after all, 19.5 watt hours, the xhp70.2, and overestimated lumen claim make it very efficient.

    Also keep in mind that 1000 lumens from one light/reflector will look different then others. You can get a 1000 lumen light that will throw 650 yards and another set up to just be a flood. So it depends on what you need the light for. Look to that. Not just lumens. Also keep in mind that there is really NO difference between say 750-800 and 1000 to your eyes. Way back and maybe still today guys would jump all over the newer version of a light because it went from 110 lumens to 125. Lol. Just keep that in mind and get the beam you want and lumens second.

    The review of the Acebeam L30 here on CPF has runtime graphs. When set to 1,000 lumens mode, the light produces a flat output of approximately 950 lumens for 2 hours and 22 minutes. After that the light drops out of regulation and output declines steeply over the next 10 minutes or so.

    That output fails to achieve OP's goal since it's still 50 lumens too low and 38 minutes too short. Still... 950 lumens for 2 hours and 22 minutes on a single-cell light is excellent. That puts it right up there with the 21700 Zebralight in terms of output and efficiency.

    There needs to be an approximate 20% increase in output before the difference is visually noticeable. So a 1000 lumen light will produce more light than than 800 lumen one ... but the difference is barely noticeable and doesn't matter for real-world use.

    That said, lumens do matter for some purposes. If I'm taking out the trash at night without dark adapted vision I need a light bright enough to illuminate wet bricks so I don't step on slugs. I can really tell the difference between an 1800 lumen light and my 4300 lumen D4.

    I assume OP wants something with continuous 3-hour runtime. Maybe for going on long walks at night or bike rides. So probably a general purpose beam.

    Not an easy EDC for sure (but I have) but my Olight X7 does 1,000 lumens for 6.5 hours. Of course I have never used it that way, my uses are different so I use it at 9,000 lumens if I need that much of a flood light. The other options above like carrying spare cells is a better option most likely for you.

    I agree completely - beam pattern is important to identify up front. What is the intended purpose of the light? As others have said you are not likely to notice the difference between a true 800 lumen light and a true 1000 lumen light, but if the beam pattern (flood versus spot, smoothness of transition, etc.) is not what you need that will become a problem real quick.

    then you go on to openly admit you are making an assumption. it is likely the OP simply wants the best that exists. any 70.2 is going to do it. xpg set ups like Zebra light are in my experience inferior.

    Get the most compact sodacan light you can find. Fireflies ROT66, Emisar D18, Manker MK36 come into mind.

    The Zebralight with a spare battery works too.

    The 21700 Zebralight OP mentions is the Zebralight SC700d. Its emitter IS an XHP 70.2. It does not use an XPG.

    ... and that Zebralight still falls well short of OP's goal.

    This is incorrect information.

    The D4v2 can easily get 4300 lumens out of the box without any programming or calibration. To get 4300 lumens just make sure you bought the XPL HI version, have a good cell inside like a Sony VTC6, then double-click when the light is on. And don't be in muggle mode. Oh and make sure the contacts on the battery tube, driver and tailcap have no debris.

    Programming doesn't affect the D4v2's ability to deliver the light's max possible turbo output in any way. All programming does is calibrate the temp sensor which controls thermal rampdown. That governs how quickly the light ramps down when it gets hot. But it doesn't affect at all what it turns on initially at.

    You can program the max ramp. But again this does not affect max turbo mode, which is not programmable and can always be accessed with a double-click from on no matter what you set the ramp to.

    Note: when you refer to "programming" I assume you mean configuring the light with the flashlight's button using Anduril's settings, and not actually going to your PC and making custom changes to Anduril's source code, and then recompiling and reflashing it. Even if you went and played with the code it's still not possible to code Anduril for any higher output, since turbo mode already delivers max possible output in stock configuration. However, if you recode it you could choose to lower the max turbo output.


    I love the D4v2. It's my current favorite EDC. I have multiple copies and have modded them and reflashed them. However, the D4 and its derivatives is not a good choice for OP. The heatsinking isn't nearly good enough to sustain 1000+ lumens. I think it settles around 400 to 500 lumens if you just let it run.

    You have not announced the budget and the required coverage range - close or long distance?

    Exists Lupine Betty TL2. According to the manufacturer, it can burn for 1400 lm for 4 hours and 1850 lm for 3 hours, but here the standard FL1 is indicated, he considers the time before lowering to 10%

    There is a company - Lucifer, they have more stringent methods of measuring the operating time, they indicate the operating time at a level until it drops to 70% of the initial value. Their model L with 4 diodes, if use a battery with 4 batteries, it works 4 hours with 1600 lm, it 1100 lm after 4 hours of work, it fits your requirements.

    If that's what he requires, then his only option is to wait a couple of years until battery tech has caught up to his demands. He's not asking for something totally unreachable, but we're not quite there yet in a pocketable size. Unless he considers a multi-cell light pocketable.

    Zebralight + spare cell is probably the most efficient option.

    A cool white low cri XHP70.2 with a high capacity 21700 or 26650 can probably do pretty close to 900-1000 lumens sustained for 3 hours. Trouble is I don't know of any lights like that that specifically have an output level around 1000 lumens. Imalent DM70 comes to mind.

    Manker U23 XHP50.2 cool white version is advertised to do 980 lumens for 2.8 hours. Manker lights are usually regulated.

    Looking at the XHP70.2 datasheet, the highest bin seems to put out 2164 lumens at 1050mA. Eye-balling the voltage curve at that level, and it seems to require 11.2v.

    So, that's an efficiency of 184 lumens/watt.

    You'd need 5.435 W for 1000 lumens, or a 16.3 Wh cell for 3 hours of use. That's a 4400 mAh cell, which is currently available in a 21700 format.

    However, that all assumes 100% efficiency of the boost-driver and optics. Realistically, you should probably drop that by 20% or more.

    Maybe we're closer than I thought. You'd still have to find the perfect light to output 1000 lumens exactly.

    What's it for? 1,000 lumens for three hours feels like a pretty arbitrary request.

    My Malkoff M91B will go two hours at full, regulated output on a pair of 18650s. Having another set of cells on my person is IMO far more preferable to holding a soda can for three hours. Two sets of extra 18650 cells will keep a Hound Dog Super (1,600 lumens/75,000 lux) running for the three hour target as well.

    Carrying extra cells is far easier than carrying a light large enough to hold them all at one time.

    nope. it gets it for 10 seconds or so then begins to turn down in output or is uncomfortable to hold because it is too hot. if yours comes at 50 degrees that's not safe nor OP. relevant.
