eBay 98kW LED flashlight (slightly exaggerated) with schematic

- Another of the many products on eBay where the sellers try to outdo each other with very ambitious ratings. Far too ambitious in this instance.
The construction of the light is interesting because it has been optimised for fast manufacture.
The circuitry is ultra minimalist, including the USB charging circuitry that doesn't inspire a lot of confidence. Don't leave one of these on continuous charge.
Other than that, it does work, the beam focus feature works well and it doesn't have too many useless modes.
The cell capacity tests at a very ungenerous 160mAh and the charge circuit does keep trickle charging the cell after the LED has stopped flashing, and when I monitored it for a while it peaked at a slightly uncomfortable 4.27V then suddenly settled back down to 4.21V, making me wonder if it had energised the load briefly when I wasn't there as part of its charge control.

I'm not buying any flashlight less than 1MW.
Good news. If you search carefully, you will find plenty of 2MW and 5MW lasers ...
Ok. What? Video is uploaded 56 minute ago and your comment is 8 days old...??? Awesome bug. 👍

@@TheLordNemesis From TH-cam? I thought Patreon has it's on video platform. OK.
Thnx for clearing my doubt.
Brave to stick your hand straight into a 98kW beam.
Hats off to Clive for risking life and limb to make us content...
😆
Balls of steel, I tell you!!!
As brave as honking those Aliexpress 600 db horns.
Krakatoa is just a whisper in Antares in comparison
98 K W Beam, effing amazing, from such a tiny power source too? Those clever people, sure you couldn't be up to them foreigners?
I'm impressed that a 160mAh battery was able to power a 98kW beam for more than 20ms
That's a 160 Amp battery.
@@solarsynapsemaybe it’s a 160mah battery at 96kV
"It's out. [snort]" It's the snort that really sells it.
Could you not love Clive enough 😂 ...... the "snort" expecting the "shaft" to expell with some resistance and yet with unimaginable ease. Cough, cough ..... it falls apart. Seriously though, HA, isn't it enough already being sold mislabelled items on Internet.
You could truly hear Clive's amusement. 😂
I also snorted a moment before the did and when he did I died XD
If you really could get 98kW from an instrument that size, the National Ignition Facility people would like to hear from you! They could replace all those expensive lasers and initiate fusion with a bunch of pen lights.
Maybe it is just extremely pulse modulated the NIF lasers are something like 500 trillion watts so if that thing is pulsed for a nanosecond or whatever perhaps it is outputting 98kW
@@glenecollins Then the shutter mechanism would be worth repurposing!
Build an artificial sun with a million of this flashlight combined and voila, UNLIMITED POWER!
@@glenecollins I seem to remember from visiting Harwell that some of the extremely powerful lasers which they have there output in one burst the same amount of energy which you'd get from eating a Mars bar. Perhaps a similar case? Vulcan - that's the chap. Each burst lasts less than a pico-second.
@@sihamhamda47 Point it at a solar cell and you would get about 20kW back. You can certainly power more than one of these lamps on that, so all you need to do is cascade lamps and solar cells until you have satisfied the entire energy needs of humanity!
The fact that it required force to disassemble and didn't just fall apart actually puts it in the top tier of ebay torches
Technical team: It's 98mW
Marketing team: Let's do a clever "typo"
It could be from one of those countries that swaps the commas and the periods for decimal separator. 98,000 watt might be 98.000 watt. Still, marketing knew what they were doing.
@@hotlavatube 98W would also be a laughable lie
@@TheGreatAtario Well, if you remove the resistor between the LED and the battery you’d probably be able to get 98 watt… for maybe a second before the LED burns out, but hey, mission accomplished!
@@hotlavatube Which resistor?
@@M4RC90 Ah right... I double checked the video and Clive did say they didn't use any resistors to limit the current. Well then, we'll just have to swap the battery with something with a little more oomph then!
My eyes still haven’t recovered from the mind blowing power of that torch
My Tablet screen melted! ... Big Clive owes me £110! 🤣
Well, I purchased a small flash light that advertised itself at being super bright, where my eyes have likely been damaged from using it. It was only 5 Watts although used a UV diode that produces UV light that can cure UV epoxy. Really burned my eyes and had giving me headaches and had me seeing spots after using. Gotta be careful of cheap Chinese cr*p!
Was several months when accidentally I noticed it could cure UV Resin, and thus was the cause of my eyesore. Now I'm paranoid of Chinese led products.
This deserves a BFI Award. Brute Force and Ignorance.
Looses a couple of points due to the lack of blood, but still near the top
th-cam.com/video/2yw6SHlE2uo/w-d-xo.htmlsi=G5S0WOpN_eWkkqxq
Assuming the LED drops 3V, then the battery must supply 32,667A. With a capacity of 160mAh, the light produces 98kW for 4.8μs. Very impressive, I think we can all agree.
I must get one to point at my solar panels to charge my Tesla on a cloudy day.
"98 Kilowatts of disappointment". Me too. I wanted to see that irritating burnt squiggle made with the Temu gismo vaporised.
Can I suggest a plumber's pipe cutter to cut through the next thin circular casing.

Or a refrigeration engineers, pipe cutter

So good that there already is one.
It's a fun song by Rory Gallagher too
I've used a 1/16 inch or 1.6mm drill bit held in a small pin vise, and I drill a small hole in the plastic. Then I screw a M3 or M2.5 by 6mm sheet metal screw into the hole I drilled. Now I have a 'handle' to grab onto with a pliers or dikes and give the plastic a strong pull. This allows getting inside to repair. 👍
Love clive's delicate little hands😊

They'd certainly make *me* weak all over... 😍🏳🌈❤🔥😇
This flashlight is so powerful you should be careful about the recoil
He really should be wearing welders' goggles for safety. One hit from that beam and you're blinded for life.
Hey China, THANKS for the flashing mode on torches - thats what was so missing in the last 100 years and thanks for the 'economic' construction so that, despite it not havinbg an incandescent filament, if you drop it once the thing stops working permanently. Thanks, just THANKS!!!
On torches with those 6-pin drivers, some of them have a dedicated pin for disabling blinking mode. Ground that pin and banish blinky mode forever. I was trying to buy some of those chips (not easy) and found that titbit in the datasheets. It was almost a life-changing moment.
Ebay watts are on a slightly different scale to regular watts.
Computer storage on AliExpress has a different scale too. I’ve seen ads posted for SSDs and flash drives ( SD & micro SD cards ) that had capacities in the petabytes (1 petabyte is 1024 terabytes, or 1000 depending on if it makes the company more money) for less than what the similar sized storage in terabytes would cost. Wish they were real as I would buy a bunch and have all of my storage space taken care of until technology makes SSDs in a RAID with hot backups unusable like a paper card reader.
@@capitalinventor4823 I once managed to „upgrade“ a fake 1GB pen drive bought on eBay to a total of 128.12GB. To do this, I cracked open the case and dropped a _genuine_ 128GB SanDisk micro SD into it... 🙃
Just like nautical miles are on a slightly different scale to regular bananas.
As a rule, I NEVER buy flashlights with non-replaceable batteries. It's just landfill-bound in short order otherwise.
A rule I also abide by, but one that is becoming increasingly difficult to uphold.
I usually follow the same rule with lights that I can’t replace the bulb. I say usually because LEDs have allowed a lot of creativity and some lamps are in shapes that could never be made with replaceable bulbs. But for any light fixture that could easily have a bulb inside and is made with an irreplaceable LED, I won’t purchase it. I know that the LEDs should last a very long time but that depends on how the company uses them for the background lighting and after approximately five years it stopped working. It was only on for a half hour after it noticed a person moving in the room, so far from five years of continuous use. After opening it up I saw that the first four or five LEDs at one end had burnt out. The company pushed the LEDs too hard and if I buy a light fixture I have no promises that the manufacturer of that won’t do the same. I’d like to replace the outside lights on my house. I’ve seen some very nice fixtures but unfortunately none of them use removable light bulbs.
Pending e-waste, just like Ear pods and every other similar product
@@_BangDroid_
I thought the business model for cordless earphones was that they would become lost way before issues concerning battery life showed up. :) It’s not uncommon to see one on the floor of public transit or on the sidewalk or platform nearby. Somebody rushes to get off or on a bus/train dropping an ear pod and they won’t stop to pick it up, if they even notice.
I apply that to ALL products. Very few cellphones have the option. There is a law suit for that right now and they are making progress. Nio is the ONLY car company making EVs correctly.
The 9 million mAh power bank would be the perfect complement for this 98 kW LED flashlight. They should start selling them as a combo.
This is just like those 300000 dB horns for sale on ebay and whatnot, enough power to completely decimate the entire universe and all of it's parallels tenfold in an instant for just 20 bucks!
I wonder if one day these incredible ebay sellers will make a flashlight powerful enough to replace the sun when it dies in a billion years 🤔
It is indeed fortunate that humanity would never abuse that kind of power!
Thank you Clive, today is a good day for a smile 😊
At 98kW that battery will last two-hundredths of a second. 😁
But the 23000 Amps will vaporize the thin cables even faster! So this has to be classified to be a bomb.
A battery with that kind of density would be much more powerful then a firecracker. 98kw is equal to about 23g of TNT... and the biggest consumer grade firework only has 50mg worth. It would go boom... and take your house with it.
The power the Chinese can squeeze from a battery is amazing! Many years ago I bought a 2KW PMPO audio amplifier. All that power was supplied through a 12V 1A power adapter!
The power of the sun in the palm of my hand
You're so good at brute force an ignorance.
And peeling metal with circuit board trimers.
Hello mister BigClive
You call it "brute force and ignorance"
I think the Danes call it "British craftsmanship".. 😂😋🤗♥️
That J3Y transistor must contain some brand new super secret chinesium technology. Switching that awesome 98kW LED and not even getting warm... wow! 🤣
MOSFETs are pretty low resistance these days, but yeah, perhaps not quite that low.
I think the cable is special one too. We have sleeped to long
How does this come out? Pull. Oh, it's out.
Not even the best that China has to offer, can match the power of a determined Scotsman! 😂
At 98,000 Watts , this should bring down enemy drones with ease ... ( ? ) ............... DAVE™🛑
Light sabre technology right here in 2024... Clive you are a lucky man. The Force is strong within you and your torch! 🌞
(What a bright guy!)
the 'brute' Force, it is.
Love it when eBay sellers forget the µ before the W
And then make claims about it not being on most keyboards when they're pulled-up on it... 😉
So, if it gets any rain on, or in it, it'll never come out agian, great!...
Nothing to stop it getting twisted and snapping the wires to the led off the board either
160mah?still 16 times bigger than what was in my smart meter!
Exaggeration of capability surpassed absurdity many years ago, but still apparently increasing. I recall the days when it was possible to rely on the power output figures of music centre manuals, in Watts RMS. But then they changed it to peak to peak, and now it seems like they think of a number and add a few zeros.
I bought two audio amps a couple of years ago, rated vaguely at 1200W. Recently while the covers were removed I checked the output transistors - which were rated at a more realistic 100W
Same thing with solar garden lights, the packaging will always show a blindingly white light being emitted many times brighter than you will find you get from the lights!
Those were watts p.m.p.o. A pathetic "marketing" tactic which replaces industry-standard ways of correctly measuring output power with whatever stupidity gives you larger numbers, to try to trick the buyer. Still, not as bad as planned obsolescence, which is like some kind of anti-engineering to deplete non-renewable resources much faster. Just reminders of how greed can drive mankind into crazyness and stupidity.
May the force be with you,Clive...
I have a similar, yet grossly less powerful lamp and unintentionally disassembled the sliding focusing bit in in a similar forceful manner. This also detached the led wires from the board.
I was able to remove the cell via inertia(this involved the wires from it being torn off as well) and used a wooden dowel to punch the switch/charge end cap out from the inside without damage.
After all the bits were extracted and connections repaired the light was reassembled and continues to function to this day.
Only slightly? I best stick around for this one 🍿
I really likes flashlights and i love when you upload a flashlight video have a nice week Clive.
А видео только сейчас выложено😮
Wow that's really powerful !
I needed a torch last night.
Walked across the living room and stubbed my foot on a metal trident.
It was a toe sting fork.
"Prepare the Photonic Cannon!"
"It's out..." Excellent!
Very nice video, I enjoyed the humour you added.
This surely comes from the same factory that also makes the infamous 600 dB car horns :-D
The one who also makes 1 billion volt tasers
Pfft that’s nothing compared to the 900dB horns you can get now 😂
LOL and what's the theoretical maximum sound pressure possible in our atmosphere? Something like 180 or 196? Gosh not only are these sellers boneheads, but they expect their buyers to be also. Bonehead-to-bonehead marketing I guess LOL
Thank you.
I run an escape room and I want to have a system where shining a UV torch on a puzzle will give you more context to it, so rather than just explain everything to kids over a clue, they can look at a picture that is invisible to non-idiots. I wanted a way of building my own rechargable uv torches and that schematic is going to help me loads!
Ask on r/flashlight for a suggestion based on your requirements. It is a good community, and someone would be able to advise a model that matches what you are looking for. There is a lot of modding advice too, with advice of what base to use it you want to fit your own LEDs.
UV LEDs can be tricky to get right though, as many „UV“ LEDs tend to emit the wrong wavelength to make UV ink show up as desired. A backup plan - If you want one - Might be to provide red or green LED torches and paint the clues in the opposite colour (So green paint, if red torches) obscured by patterns in the same colour. 😇
You'll be familiar with this idea if you ever used 1st generation 3D glasses. 🟢👓🔴😇
I have a fairly similar one.
Got one for my gran and was impressed at the £4 price point.
Mine does have the obligatory SOS mode when you hold the button in.
Pretty bright too, was using it to find my way to a rave in the middle of a forest.
might see if I can change the battery out with one or two of my street lithium cells.
The ones with 3xAAA in the holder will almost take a street lithium 18450. They're just a tad too short and need a bit of padding to fit snugly, but that's easily solved. Twice the capacity of most NiMh as well.
That's pretty close to interest territory of Photonic Induction!
"Slightly exaggerated power rating" 🤣🤣
Wow, I can't believe you didn't put on appropriate PPE before handling that death beam. What are those power wires made of? A new superconductor material of unknown origin ?
*Chinesium* 🪨, probably... 😉
Wow! I'm going to get me one of those.
I’m holding out for the 98MW version.
I bought this exact torch but in black. It was reasonably cheap, but not cheap enough. I bought a Sofirn SC18 at the same time and I will say I the Sofirn is *amazing* value for money, while with this thing I felt was terrible value.
I, of course took mine apart too. Managed to get the end cap out by leveraging from the charge port.
The BLF A6 is my go-to flashlight, developed by budgetlightforum users, sadly discontinued so bought 3 when I last saw them on sale.
A very tough 18650 powered Cree driven waterproof torch, the single click switch which has some nice features by half-pressing the button for 0.5 seconds; 7 brightness levels, strobe, battery charge level (1 blink=25%, 2 blinks=50% etc.), and a bike flashing mode.
Of course a light designed by committee has strobe

I have several 1600 lumen BLF A6's. I LIKE em also

The way you open some of these items reminds me of those old fashioned tin cans that have a "wingnut" that you twist to peel away a metal strip to open the can.
Thank you for showing a way to open this lamp!
Now I know how to open my lamp without damage ... hopefully.
The charging is medium smart. Over the 100 Ohm Resistor there is a current flow and this activates the transistor. With one pin it measures the voltage and if this is ~4.2V the pin which is going to the base of the transistor is switching to GND, so the current flow stops.
Stupid is, that there is no current limitation, only the limitation of the power-supply and the wiring. With 160mAh there is very easy a overcurrent and very fast charging. Not good. It is worth to open this device.
How can you possibly know the safe charging/discharging rate of this battery with just its capacity?
In fact, there is a correlation between the two that suggests this quite large battery with an unusually low capacity is made for relatively high current like 5 or 10C. That's how a standard 18650 sized Li-ion like a Sony VTC6 can safely output 40A.

1. This is a China LiIon-Cell. Mostly there is a old laptop cell in this lamps.
2. For this price you do not get a high quality LiIon-cell. If you know china and chinese products, you would not believe that they put a very good cell into this lamp.
3. A very good LiIon-Cel for high current has only 1600mAh, the cells with a higher internal resistance have 2000 or 2500mAh.
Even if they use more copper to reduce the resistance, then the electrodes are not better. With a high charging current you create always Lithium-dendrites. The cell can handle the current, but it get damaged too.
The discharging with a high current is not a problem. There the more copper make sense.
But this device do not have a current limitation, only the resistance of the cable. This is not safe.
I was looking forward to a maximum power test on the LED. Just to see what the max sustained power it could handle was.
I suspect the controller PWM limits the current.
to be fair: i got two of them on ali just for the good focus....

I always wondered if a good quality cell would kill the LED as it packs a "little bit" more punch into the circuit when powered on. I have several cheap USB rechargeable lights, just like that, for emergency. They do their job well, even after a few years, but I wonder if the LED current limit is done by the usage of 800mAh 18650 cells 😊
It's a typo. It was supposed to be a "m" not a "k" 😂
98kW -> 98mW
Hi Clive, Great video as always. I must admit to liking these little torches and have quite a few.
I was wondering if you could help me find some good quality solder wire leaded at a decent price. Most of the cheap solder on eBay is crap (sludgey and dull with a high melting temperature), but the quality solder wire seems outrageously expensive at over £50.00 or more for a 500 Grams Reel. Do you know a source of decent priced quality Solder Wire?
Many thanks Clive.
Keep well and stay safe,
Joe
It's 10 times the power of my electric shower 🤣🤣🤣🤣
Does it come with its own inverter Clive ?😱😱😱😱😱😱
Our local Heritage Railway at Christmas time runs the Pola Express theme and the company who runs it gave away flash lights almost the same as your flash light and I have one. It has a main light and a side LED light. So press button once it's main beam with a siding bit to focus the light. Press twice and it strobe light. Press three and it's the side light. It only has about 50 minutes of light before I have to recharge it. But it was a free
I recently bought one of those radio transmitter kits, it was advertised as having a 50 milliwatt output but when it turned up it stated 50MW in the specs on the construction sheet that came with it. It's a real feat of engineering how much it's little output transistor is capable of, I will have offcom kicking my front door in with fifty million watts and an eye watering electric bill.
Maybe it's 98kW EIRP (Equivalent isotropic radiated power), incandescent equivalent, using whatever method they use to rate shop vac motors at 6.5 horsepower?
In other words, what is the power of an incandescent bulb that shines in all directions with the same brightness as the focused beam of the flashlight, but at initial power on when the filament is cold and draws more power?
As a European, 98,000 Watt is, well, just shy of 100 watt. Keep in mind that we use the comma as the decimal separatator instead of the US customary thousand separator.
And while that is _wildly_ off the mark for this form factor, getting 100 watt-ish output from a high quality 18650 cell is not that unrealistic.
These lumen specs are like the range in a Tesla. But, I just purchased a Lumintop® GT4695 flashlight recently and remembered your video. If you get your hands on one, you might enjoy the advancements in their circuitry and design.
It's actually quite clever industrial design.
Nice.
I have pretty much the same flashlight but it is black... and also UV.
Mine has a problem with the micro USB port where it gets pushed in when I try to plug a charger to it so it has no contact. Now I know...
I don't prefer the use of foam as a way to stop PCB from moving back and forward. But it is a cheap way to make a cheap flashlight so I get it.
So the only problem is that I cannot charge it... and that is an issue.
THAT CASING STARTED TO FAINT WHEN IT SAW YOU COMING!!!
Serviceable, I am up for that
Apart from the underspec battery it's actually quite a nice product
I bought a copule of those in Aliexpress. The model with an extral pretty decent cob led on the side (that might explain the very little battery chosen), which used sideways are good headlamps with a 3d printend strap.
Sadly, the battery is so tiny they run out of juice in a couple minutes. Pretty bad. I have them demoted as emercency units gathering dust in "that flashlaight drawer" in case lights go out (to use to hopefully run long enough to just find the proper 18650 based flashlights that I literally carry around every day.
Of those 1860 ones, I have a also Chinese Convoy S2+ that I love, last years in a sensible power mode, and gives proper uumph when set high. Sadly it has a "programmable" driver that can be set to roll through several blinking modes that I hate. Is there a way to hack those MCUs into different modes? That might be an interesting video there (interesting only to me, I mean).
"...by brute force and ignorance" finally a name for tecnique and set of skills I was born with!
Educative and brilliant, as always. Thanks!
I feel your level of sarcasm has risen to another level. 😂 i like it.
I'd bought three copies of a single-AA-cell flashlight from a local store, a few years ago, and had to modify ALL of them because they didn't have a wide enough beam. Fortunately, all metal, so I just needed to unscrew the ring holding the front lenses on, slide a ring made of aluminum wire in behind the LED's backplate, and close everything back up again.
Now my only complaint is how dim it gets when the battery gets halfway used...
These small flashlights are all the same. I bought a couple of these a few years ago. They look different but the insides are identical. They don´t last very long but they are a great help.
torque test channel Need to test this!!!
If I'm not mistaken the most powerful commercially-available "flashlight" is something like 1kW, is much larger, and has cooling fans. 98kW is an order of magnitude than even styropyro would do.

Bro used bruteforce Attack
And all guys were like, yeess, me too
Was there a way to cross-reference the main led to a clone or a Cree type, I understand that there are many types, but did it look familiar?
Cannot say i am surprised, i got ripped off buying one of these supposedly (light up the side of a building or the whole street type mag light). Seemed like a good idea, as i use a rudementry version as my pushbike headlight. Can only be better? or so i thought. What turned up is in fact a mini light, suitable for a handbag maybe to help you see your keyhole, but also no return address, well only in Chinese, nothing in image to show scale, the advertised one at £17:00 looked great for what i wanted, but shown as being larger than the user's hand, whereas mine is about 2 inches long, no adjustment other than, on flash, S.O.S. so relegated to bedside table in case of power cut.
Varying the scale of item photos is now a common trick, and is why I stopped buying things from Amazoff. There's a widely known meme of a „Desk organiser“ which shows an iPhone 6 on one of the lower shelves. Just see what happens when you try to put a *real* iPhone 6 (Not a dolls house miniature) in the same place... 🙃
I was doing time at Riker's for 3 years and have missed a ton of episodes. What caused the wormy/wiggly burn mark on BC's workbench?
It's a shame it didn't come in your trademark fetching pink.
I like em single mode, dim and warm white
It's a shame we didn't get a measurement of the current through the LED, because I suspect it's not even 98mW!
Current? He'd be lucky to find a whole Rasin! 🙃
Perhaps the space for the extra LED near the charging indicator is to hold an LED to indicate the power is on. If the company may use the board for more than product then the need for such an indicator may be required. An LED to tell tell the user that a flashlight is turned on would seem to be rather redundant. (Unless the flashlight was emitting non visible light, such as infrared.)
You need to get a c-clamp style tubing cutter, like what's used for copper pipe. That would make short, clean work of things like this.
14500 li-io battery. Same size as AA. I use them in my fancy homemade garden lights.
Is there any way to disable the strobe/sos function? Every flashlight has that function, and I really hate having to click repeatedly just to get a constant light.
Almost like 1.21 jigga-watts :)
Amazon has a huge number of misrepresented flashlights of varying degrees of quality. Sometimes you'll get lucky and get a decent flashlight, but the odds are stacked against you. Generally their components are very similar to the one you took apart in this video. A "high power" grid LED connected to a minimalist circuit and a poor quality lithium battery all stuffed in a cylindrical case. Some of the flashlight cases are quite decent quality in order to give a better feel and appearance to the flashlight. The brightness is generally on the order of 1000 lumens. The postings, however, will claim 100k to 1 million lumens. The posting will also almost always over-estimate the battery capacity to sometimes absurd levels.
This problem also applies to lasers listed on Amazon. However, in the case of lasers, this is very dangerous. Also, unlike the flashlights, the misrepresentation can often be an under-representation rather than over. This means that a green LED laser will claim a Class 2 "safe" < 1mW rating, while actually being dangerously high. This is because, like the flashlight circuit you disassembled, there is no current regulation going to the LED. I have a class 3 25mW green laser off Amazon that, at full charge, is close to 500mW and _will_ injure eyes across a gymnasium.
Amazing 98kW didn’t vaporize your work bench!
It was on ultra low. 😉 Clive is safe.
Bench is made of Unobtanium.
Clive, you missed the mode that completely discharges the batteries in one attosecond to produce the 98kW pulse . . . do not use unless you want to be near an explosion and/or receive massive!!!!! radiation burns.
I had a great laugh at the power of that amazing flashlight. Given that 100kW laser systems are used to cut metal, etc., and are the size of a large pick up truck. I’m just impressed by the micro miniaturization that they obviously managed to accomplish. 😂
Wow you could see that beam from the moon!
I kind of wonder how they get these crazy numbers. Maybe its the LED watt output times the cell mAh times the estimated charge/discharge cycles?
That would've been my Blue Peter drawing of future tech, lipstick sized, pocket torch with an output of 98kW (lasting several hours) that would illuminate an entire field. Useful for the police ....
